LSAT PREP TEST QUESTIONS Flashcards
LSAT Logical Reasoning Prep Test 52 Question #1 Certain companies require their managers to rank
workers in the groups they supervise from best to
worst, giving each worker a unique ranking based on
job performance. The top 10 percent of the workers
in each group are rewarded and the bottom 10
percent are penalized or fired. But this system is
unfair to workers. Good workers could receive low
rankings merely because they belong to groups of
exceptionally good workers. Furthermore, managers
often give the highest rankings to workers who share
the manager’s interests outside of work.
Which one of the following most accurately expresses
the conclusion drawn in the argument?
(A) Some companies require their managers to give
unique rankings to the workers they supervise.
(B) Under the ranking system, the top 10 percent of
the workers in each group are rewarded and the
bottom 10 percent are penalized or fired.
(C) The ranking system is not a fair way to determine
penalties or rewards for workers.
(D) Workers in exceptionally strong work groups are
unfairly penalized under the ranking system.
(E) Managers often give the highest rankings to
workers who share the manager’s outside
interests.
Correct Answer: C
C Main Point
This argument disagrees with the compensation system companies use requiring managers to first rank their workers from best to worst, and then reward the top 10 percent in each group and penalize or fire the workers in the bottom 10 percent. The argument concludes that this system is unfair to workers. The premises are that the rankings depend too much on the quality of the workers with whom each worker is grouped. Also, managers often rank workers for the wrong reasons, such as affinity.
A. No. This is a premise.
B. No. This is a premise.
C. Yes. This is a good restatement of the disagreement.
D. No. This is a premise.
E. No. This is a premise.
LSAT Logical Reasoning Prep Test 52 Question #2 Psychologist: A study of 436 university students
found that those who took short naps
throughout the day suffered from insomnia
more frequently than those who did not.
Moreover, people who work on commercial
fishing vessels often have irregular sleep
patterns that include frequent napping, and
they also suffer from insomnia. So it is very
likely that napping tends to cause insomnia.
The reasoning in the psychologist’s argument is most
vulnerable to criticism on the grounds that the
argument
(A) presumes, without providing justification, that
university students suffer from insomnia
more frequently than do members of the
general population
(B) presumes that all instances of insomnia have
the same cause
(C) fails to provide a scientifically respectable
definition for the term “napping”
(D) fails to consider the possibility that frequent
daytime napping is an effect rather than a
cause of insomnia
(E) presumes, without providing justification, that
there is such a thing as a regular sleep pattern
for someone working on a commercial fishing
vessel
Correct Answer: D
D Flaw
The argument presents a causal interpretation of evidence. The psychologist concludes that napping is likely to cause insomnia because two groups of people who nap more suffer more from insomnia.
A. No. The argument does not compare university students to the general population, but rather university students who nap to those who do not.
B. No. The argument does not assume that napping is the only cause of insomnia, just that it tends to cause insomnia.
C. No. The argument uses the term “napping” consistently and does not need to define it.
D. Yes. The argument fails to rule out the possibility that the causal direction might be reversed.
E. No. This is not essential to the argument.
LSAT Logical Reasoning Prep Test 52 Question #3 Whenever Joe’s car is vacuumed, the employees of
K & L Auto vacuum it; they are the only people who
ever vacuum Joe’s car. If the employees of K & L Auto
vacuumed Joe’s car, then Joe took his car to K & L
Auto to be fixed. Joe’s car was recently vacuumed.
Therefore, Joe took his car to K & L Auto to be fixed.
The pattern of reasoning exhibited by the argument
above is most similar to that exhibited by which one
of the following?
(A) Emily’s water glass is wet and it would be wet
only if she drank water from it this morning.
Since the only time she drinks water in the
morning is when she takes her medication,
Emily took her medication this morning.
(B) Lisa went to the hair salon today since either
she went to the hair salon today or she went
to the bank this morning, but Lisa did not go
to the bank this morning.
(C) There are no bills on John’s kitchen table. Since
John gets at least one bill per day and he
always puts his bills on his kitchen table,
someone else must have checked John’s mail
today.
(D) Linda is grumpy only if she does not have her
coffee in the morning, and Linda does not
have her coffee in the morning only if she
runs out of coffee. Therefore, Linda runs out
of coffee only on days that she is grumpy.
(E) Jeff had to choose either a grapefruit or cereal
for breakfast this morning. Given that Jeff is
allergic to grapefruit, Jeff must have had
cereal for breakfast this morning.
Correct Answer: A
A Parallel
Diagram the argument. Joe’s car is vacuumed → K & L vacuumed it. K & L vacuumed it → Joe took it to K & L to be fixed. The argument demonstrates that the sufficient factor (Joe’s car is vacuumed) is valid. Therefore, the result (Joe took his car to K & L to be fixed) must also be true.
A. Yes. Emily’s glass is wet → she drank water from it this morning → she took her medication. Emily’s glass is wet, so she must have taken her medication.
B. No. There is no either/or option in the original argument.
C. No. This answer choice does not match the structure of the original argument.
D. No. This answer choice demonstrates flawed reasoning and the original argument does not.
E. No. There is no either/or option in the original argument.
LSAT Logical Reasoning Prep Test 52 Question #4 Editorialist: In a large corporation, one of the
functions of the corporation’s president is to
promote the key interests of the shareholders.
Therefore, the president has a duty to keep the
corporation’s profits high.
Which one of the following, if true, would most
strengthen the editorialist’s argument?
(A) Shareholders sometimes will be satisfied even
if dividends paid to them from company
profits are not high.
(B) The president and the board of directors of a
corporation are jointly responsible for
advancing the key interests of the
shareholders.
(C) Keeping a corporation’s profits high is likely to
advance the important interests of the
corporation’s shareholders.
(D) In considering where to invest, most potential
shareholders are interested in more than just
the profitability of a corporation.
(E) The president of a corporation has many
functions besides advancing the important
interests of the corporation’s shareholders.
Correct Answer: C
C Strengthen
The editorialist concludes that the president has a duty to keep the corporation’s profits high. The premise is that one of the functions of the president is to promote the key interests of the stockholders. The argument would benefit from a connection between the key interests of the stockholders and high profits.
A. No. This answer choice would, if anything, weaken the argument.
B. No. The argument is concerned with the president and what he/she should do, not the board of directors.
C. Yes. This answer choice provides a strong connection between the key interests of the shareholders and keeping the profits high.
D. No. The argument does not imply that profitability is the only interest of the shareholders.
E. No. Like (D), the argument does not imply that advancing the important interests of shareholders is the president’s only responsibility.
LSAT Logical Reasoning Prep Test 52 Question #5 Everyone in Biba’s neighborhood is permitted to
swim at Barton Pool at some time during each day
that it is open. No children under the age of 6 are
permitted to swim at Barton Pool between noon and
5 P.M. From 5 P.M. until closing, Barton Pool is
reserved for adults only.
If all the sentences above are true, then which one of
the following must be true?
(A) Few children under the age of 6 live in Biba’s
neighborhood.
(B) If Biba’s next-door neighbor has a child under
the age of 6, then Barton Pool is open before
noon.
(C) If most children who swim in Barton Pool
swim in the afternoon, then the pool is
generally less crowded after 5 P.M.
(D) On days when Barton Pool is open, at least
some children swim there in the afternoon.
(E) Any child swimming in Barton Pool before
5 P.M. must be breaking Barton Pool rules.
Correct Answer: B
B Inference
This is a connect-the-facts inference with conditionals. Live in Biba’s neighborhood → permitted to swim at some time each day. Under 6 → can’t swim between noon and 5 P.M. Child → can’t swim from 5 P.M. until closing.
A. No. You can’t prove how many, if any, children live in Biba’s neighborhood.
B. Yes. Children under 6 can’t swim in the pool from noon until closing. Yet, as the passage says, everyone that lives in the neighborhood must be able to swim at some time during the day. This child would have to be able to swim before noon.
C. No. The argument does not provide any information to determine how crowded the pool will be.
D. No. The argument does not explain who lives in Biba’s neighborhood. It could be a neighborhood with no children.
E. No. The pool could be open before noon. Also, it’s only children under 6 that are not allowed to swim between noon and 5 P.M.
LSAT Logical Reasoning Prep Test 52 Question #6 Beck: Our computer program estimates municipal
automotive use based on weekly data. Some
staff question the accuracy of the program’s
estimates. But because the figures it provides
are remarkably consistent from week to week,
we can be confident of its accuracy.
The reasoning in Beck’s argument is flawed in that it
(A) fails to establish that consistency is a more
important consideration than accuracy
(B) fails to consider the program’s accuracy in
other tasks that it may perform
(C) takes for granted that the program’s output
would be consistent even if its estimates were
inaccurate
(D) regards accuracy as the sole criterion for
judging the program’s value
(E) fails to consider that the program could
produce consistent but inaccurate output
Correct Answer: E
E Flaw
The purpose of this argument is to disagree with a claim. Beck concludes that, despite what some of the staff says, they can be confident of their computer program’s accuracy because the figures that the program provides are consistent from week to week. Beck equates consistency with accuracy.
A. No. The argument doesn’t claim that consistency is more important than accuracy. It equates the two.
B. No. The argument is concerned with only one task: estimating the municipal automotive use.
C. No. The argument takes for granted that, because the output is consistent, the program must be accurate.
D. No. The argument is concerned with only the accuracy of the program. It doesn’t make any claims about the program’s value in general.
E. Yes. The argument assumes that, because the output is consistent, the program must be accurate.
LSAT Logical Reasoning Prep Test 52 Question #7 Inertia affects the flow of water pumped through a
closed system of pipes. When the pump is first
switched on, the water, which has mass, takes time to
reach full speed. When the pump is switched off,
inertia causes the decrease in the water flow to be
gradual. The effects of inductance in electrical
circuits are similar to the effects of inertia in water
pipes.
The information above provides the most support
for which one of the following?
(A) The rate at which electrical current flows is
affected by inductance.
(B) The flow of electrical current in a circuit
requires inertia.
(C) Inertia in the flow of water pumped by an
electrically powered pump is caused by
inductance in the pump’s circuits.
(D) Electrical engineers try to minimize the effects
of inductance in electrical circuits.
(E) When a water pump is switched off it
continues to pump water for a second or two
Correct Answer: A
A Inference
The argument describes how inertia affects the flow of water pumped through a closed system of pipes. It then equates the effects of inductance in electrical circuits with the effects of inertia in water pipes.
A. Yes. If the effects of inductance are similar to the effects of inertia, and inertia affects the flow of water, then inductance will affect the flow of electrical current.
B. No. Inertia refers to water and pipes, not the flow of electrical current.
C. No. You cannot prove how inductance affects inertia from the information provided.
D. No. You cannot prove anything about electrical engineers from the information provided.
E. No. This choice is too strong. All you can prove is that the inertia causes the decrease in the water flow to be gradual. You cannot prove how long this takes.
LSAT Logical Reasoning Prep Test 52 Question #8 Journalist: To reconcile the need for profits sufficient
to support new drug research with the moral
imperative to provide medicines to those who
most need them but cannot afford them, some
pharmaceutical companies feel justified in
selling a drug in rich nations at one price and
in poor nations at a much lower price. But this
practice is unjustified. A nation with a low
average income may still have a substantial
middle class better able to pay for new drugs
than are many of the poorer citizens of an
overall wealthier nation.
Which one of the following principles, if valid, most
helps to justify the journalist’s reasoning?
(A) People who are ill deserve more consideration
than do healthy people, regardless of their
relative socioeconomic positions.
(B) Wealthy institutions have an obligation to
expend at least some of their resources to
assist those incapable of assisting themselves.
(C) Whether one deserves special consideration
depends on one’s needs rather than on
characteristics of the society to which one
belongs.
(D) The people in wealthy nations should not have
better access to health care than do the people
in poorer nations.
(E) Unequal access to health care is more unfair
than an unequal distribution of wealth.
Correct Answer: C
C Principle Strengthen
The purpose of this argument is to disagree with a claim. The journalist thinks that the pharmaceutical companies are not justified in selling a drug in rich nations at one price and in poor nations at another price. The journalist’s premise is that many individuals in poorer nations might be better able to pay for new drugs than poorer individuals in nations with higher overall wealth.
A. No. The argument doesn’t compare ill people to healthy people.
B. No. This answer choice supports the position that the argument is designed to disagree with.
C. Yes. This answer choice points out that special consideration should be provided to individuals when individuals within a society might not have the same amount of resources as the society does, on average.
D. No. This answer choice is not relevant to the argument.
E. No. The argument does not discuss the fairness of unequal distribution of wealth.
LSAT Logical Reasoning Prep Test 52 Question #9 9. Robert: The school board is considering adopting a
year-round academic schedule that eliminates
the traditional three-month summer vacation.
This schedule should be adopted, since
teachers need to cover more new material
during the school year than they do now.
Samantha: The proposed schedule will not permit
teachers to cover more new material. Even
though the schedule eliminates summer
vacation, it adds six new two-week breaks, so
the total number of school days will be about
the same as before.
Which one of the following, if true, is a response
Robert could make that would counter Samantha’s
argument?
(A) Teachers would be willing to accept
elimination of the traditional three-month
summer vacation as long as the total vacation
time they are entitled to each year is not
reduced.
(B) Most parents who work outside the home find
it difficult to arrange adequate supervision
for their school-age children over the
traditional three-month summer vacation.
(C) In school districts that have adopted a yearround schedule that increases the number of
school days per year, students show a deeper
understanding and better retention of new
material.
(D) Teachers spend no more than a day of class
time reviewing old material when students
have been away from school for only a few
weeks, but have to spend up to a month of
class time reviewing after a three-month
summer vacation.
(E) Students prefer taking a long vacation from
school during the summer to taking more
frequent but shorter vacations spread
throughout the year.
Correct Answer: D
D Weaken
Robert is trying to solve a problem and Samantha claims that he hasn’t solved it. Robert concludes that the school board should adopt a year-round academic schedule because teachers need to cover more new material during the school year than they do now. Samantha claims that the new school schedule won’t permit the teachers to cover any more new material because the amount of vacation will be the same as before, just in a different configuration. The students will have six two-week breaks, instead of one three-month break.
A. No. This doesn’t address the problem of needing to cover more new material.
B. No. This answer choice does not address the problem of needing to cover more new material.
C. No. It’s nice that students show a deeper understanding of the material in year-round schools, but the answer choice does not address the issue at hand: needing to cover more new material.
D. Yes. If the teachers have to spend significantly less class time reviewing material after the short breaks in the year-round schedule than after the long break in the traditional schedule, then teachers will have more class days to cover new material.
E. No. Student preference is not relevant. The disagreement is about the amount of new material that could be covered.
LSAT Logical Reasoning Prep Test 52 Question #10 In order to reduce traffic congestion and raise
revenue for the city, the mayor plans to implement a
charge of $10 per day for driving in the downtown
area. Payment of this charge will be enforced using a
highly sophisticated system that employs digital
cameras and computerized automobile registration.
This system will not be ready until the end of next
year. Without this system, however, mass evasion of
the charge will result. Therefore, when the mayor’s
plan is first implemented, payment of the charge will
not be effectively enforced.
Which one of the following is an assumption on
which the argument depends for its conclusion to be
properly drawn?
(A) The mayor’s plan to charge for driving
downtown will be implemented before the
end of next year.
(B) The city will incur a budget deficit if it does
not receive the revenue it expects to raise
from the charge for driving downtown.
(C) The plan to charge for driving downtown
should be implemented as soon as payment of
the charge can be effectively enforced.
(D) Raising revenue is a more important
consideration for the city than is reducing
traffic congestion.
(E) A daily charge for driving downtown is the
most effective way to reduce traffic
congestion.
Correct Answer: A
A Necessary Assumption
The argument concludes that the mayor’s plan to reduce congestion and raise revenue by charging $10 per day for driving in the downtown area will not be effectively enforced when it is first implemented. The premises are that payment will be enforced by a highly sophisticated system that will not be ready until the end of next year, and that many people will avoid paying the charge without this system in place.
A. Yes. It is essential to the argument that the plan be in place before the system is ready at the end of next year.
B. No. The argument does not discuss the possibility of a budget deficit.
C. No. The argument is concerned with whether the plan will be effectively enforced when it is first implemented, not when it should be implemented.
D. No. The argument does not compare the importance of raising revenue versus reducing traffic congestion.
E. No. Too strong. The argument doesn’t need to say that a daily charge is the most effective way to reduce traffic congestion.
LSAT Logical Reasoning Prep Test 52 Question #11 A recent study revealed that the percentage of people
treated at large, urban hospitals who recover from
their illnesses is lower than the percentage for people
treated at smaller, rural hospitals.
Each of the following, if true, contributes to an
explanation of the difference in recovery rates
EXCEPT:
(A) Because there are fewer patients to feed,
nutritionists at small hospitals are better able
to tailor meals to the dietary needs of each
patient.
(B) The less friendly, more impersonal atmosphere
of large hospitals can be a source of stress for
patients at those hospitals.
(C) Although large hospitals tend to draw doctors
trained at the more prestigious schools, no
correlation has been found between the
prestige of a doctor’s school and patients’
recovery rate.
(D) Because space is relatively scarce in large
hospitals, doctors are encouraged to minimize
the length of time that patients are held for
observation following a medical procedure.
(E) Doctors at large hospitals tend to have a
greater number of patients and consequently
less time to explain to staff and to patients
how medications are to be administered.
Correct Answer: C
C Resolve/Explain
There is a discrepancy in recovery rates between people treated at large, urban hospitals and people treated at smaller, rural hospitals. People treated at smaller, rural hospitals have a higher rate of recovery. Eliminate any answer choices that help resolve the discrepancy.
A. No. If the patients at smaller hospitals are more likely to get fed according to their dietary needs, they might be more likely to recover from their illnesses.
B. No. If patients at larger hospitals are more stressed than patients at smaller hospitals, that might adversely affect their recovery rate.
C. Yes. This answer choice states that there has been no correlation found between the prestige of a doctor’s school and patients’ recovery rates. In no way is this relevant to explaining the differing recovery rates of patients treated at larger or smaller hospitals.
D. No. If patients are not observed for as long, there is a greater chance that an unobserved complication might occur, thus adversely affecting the recovery rate for patients treated at larger hospitals.
E. No. If the staff and patients do not get explanations about the administration of their medications, improper administration of these medications is more likely to occur. This would adversely affect the recovery rates of patients treated at larger hospitals.
LSAT Logical Reasoning Prep Test 52 Question #12 12. Perry: Worker-owned businesses require workers to
spend time on management decision-making
and investment strategy, tasks that are not
directly productive. Also, such businesses have
less extensive divisions of labor than do
investor-owned businesses. Such inefficiencies
can lead to low profitability, and thus increase
the risk for lenders. Therefore, lenders seeking
to reduce their risk should not make loans to
worker-owned businesses.
Which one of the following, if true, most seriously
weakens Perry’s argument?
(A) Businesses with the most extensive divisions of
labor sometimes fail to make the fullest use of
their most versatile employees’ potential.
(B) Lenders who specialize in high-risk loans are
the largest source of loans for worker-owned
businesses.
(C) Investor-owned businesses are more likely
than worker-owned businesses are to receive
start-up loans.
(D) Worker-owned businesses have traditionally
obtained loans from cooperative lending
institutions established by coalitions of
worker-owned businesses.
(E) In most worker-owned businesses, workers
compensate for inefficiencies by working
longer hours than do workers in investorowned businesses.
Correct Answer: E
E Weaken
Perry concludes that lenders who are seeking to reduce their risk should not make loans to worker-owned businesses. This is because worker-owned businesses require workers to spend time on management and investment, which are not directly productive. Worker-owned businesses also have less extensive divisions of labor than do investor-owned businesses. These inefficiencies can lead to low profitability, which would increase risk for lenders. An issue with Perry’s argument is that, just because inefficiencies can lead to low profitability, it doesn’t mean that they will. Maybe there is something unique about worker-owned businesses that will overcome this problem.
A. No. Businesses with the most extensive divisions of labor can sometimes fail to make the fullest use of their most versatile employees’ potential and still be more efficient, on average, than the worker-owned businesses and still be, on average, the safer investment.
B. No. This answer choice is a description of the lenders who do make loans to worker-owned businesses. It does not address the warning against lending to worker-owned businesses.
C. No. The argument is not concerned with start-up loans, nor is it concerned with who actually gets loans.
D. No. This answer choice does not give a reason as to why worker-owned businesses might be a less risky investment than the argument claims.
E. Yes. If the workers work longer hours, the inefficiencies might be compensated for, which means that the inefficiencies won’t necessarily lead to low profitability. If they don’t lead to low profitability, then the risk will not necessarily increase for lenders.
LSAT Logical Reasoning Prep Test 52 Question #13 13. Some paleontologists believe that certain species of
dinosaurs guarded their young in protective nests
long after the young hatched. As evidence, they cite
the discovery of fossilized hadrosaur babies and
adolescents in carefully designed nests. But similar
nests for hatchlings and adolescents are constructed
by modern crocodiles, even though crocodiles guard
their young only for a very brief time after they
hatch. Hence, .
Which one of the following most logically completes
the argument?
(A) paleontologists who believe that hadrosaurs
guarded their young long after the young
hatched have no evidence to support this
belief
(B) we will never be able to know the extent to
which hadrosaurs guarded their young
(C) hadrosaurs guarded their young for at most
very brief periods after hatching
(D) it is unclear whether what we learn about
hadrosaurs from their fossilized remains tells
us anything about other dinosaurs
(E) the construction of nests for hatchlings and
adolescents is not strong evidence for the
paleontologists’ belief
Correct Answer: E
E Main Point
This argument is designed to disagree with a claim. The argument disagrees with some paleontologists, who believe that certain dinosaurs guarded their young in protective nests long after the young hatched. The evidence cited for the paleontologists’ claim is the discovery of fossilized hadrosaur babies and adolescents in carefully designed nests. In disagreeing with these paleontologists, the argument notes that modern crocodiles construct similar nests, even though these crocodiles don’t guard their young for long. The argument seems to be leading to the conclusion that the evidence of fossilized nests is not enough to claim that the dinosaurs guarded their young long after the young hatched.
A. No. This answer choice is too strong. The paleontologists do have some evidence, just not enough to fully support their conclusion.
B. No. This answer choice is too strong. The evidence cited is not strong enough for the paleontologists’ conclusion. That’s not to say that we will never know the extent to which hadrosaurs guarded their young.
C. No. This answer choice is too strong. There is not enough evidence to know that they guarded their young for large periods of time. That’s not to say that hadrosaurs couldn’t have actually guarded their young for large periods of time.
D. No. This is not the disagreement. The paleontologists are making a claim about a certain species of dinosaurs, not all dinosaurs.
E. Yes. The argument disagrees with the paleontologists as to the strength of the evidence that supports their belief.
LSAT Logical Reasoning Prep Test 52 Question #14 14. For one academic year all the students at a high
school were observed. The aim was to test the
hypothesis that studying more increased a student’s
chances of earning a higher grade. It turned out that
the students who spent the most time studying did
not earn grades as high as did many students who
studied less. Nonetheless, the researchers concluded
that the results of the observation supported the
initial hypothesis.
Which one of the following, if true, most helps to
explain why the researchers drew the conclusion
described above?
(A) The students who spent the most time
studying earned higher grades than did some
students who studied for less time than the
average.
(B) The students tended to get slightly lower
grades as the academic year progressed.
(C) In each course, the more a student studied, the
better his or her grade was in that course.
(D) The students who spent the least time studying
tended to be students with no more than
average involvement in extracurricular
activities.
(E) Students who spent more time studying
understood the course material better than
other students did.
Correct Answer: C
C Resolve/Explain
The apparent paradox is that when researchers tested the hypothesis that studying more increased a student’s chances of earning a higher grade, the students who spent the most time studying did not earn grades as high as did many students who studied less. Yet, the researchers concluded that the results supported their hypothesis.
A. No. This doesn’t resolve the apparent paradox. The passage says that many students who studied less earned higher grades. This still leaves room for some students who studied less to get lower grades, while still maintaining the seeming paradox.
B. No. If all the students tended to get slightly lower grades as the year progressed, the problem still remains that many students who studied less will have higher grades than the students who spent the most time studying.
C. Yes. This resolves the apparent paradox. If each individual student does better in a given class if he or she studies, then it looks like studying more will increase a student’s change of getting a higher grade, even if the students who study the most get lower grades than many who don’t study as much. The hypothesis was about an individual’s grades, while the statistics were about the students considered in groups.
D. No. This does not resolve the apparent paradox.
E. No. This does not resolve the apparent paradox as well as (C) because it doesn’t directly connect studying with an individual’s chances of getting a better grade in a given class.
LSAT Logical Reasoning Prep Test 52 Question #15 15. Researchers had three groups of professional cyclists
cycle for one hour at different levels of intensity.
Members of groups A, B, and C cycled at rates that
sustained, for an hour, pulses of about 60 percent, 70
percent, and 85 percent, respectively, of the
recommended maximum pulse rate for recreational
cyclists. Most members of Group A reported being
less depressed and angry afterward. Most members of
Group B did not report these benefits. Most
members of Group C reported feeling worse in these
respects than before the exercise.
Which one of the following is most strongly
supported by the information above?
(A) The higher the pulse rate attained in sustained
exercise, the less psychological benefit the
exercise tends to produce.
(B) The effect that a period of cycling has on the
mood of professional cyclists tends to depend
at least in part on how intense the cycling is.
(C) For professional cyclists, the best exercise from
the point of view of improving mood is
cycling that pushes the pulse no higher than
60 percent of the maximum pulse rate.
(D) Physical factors, including pulse rate,
contribute as much to depression as do
psychological factors.
(E) Moderate cycling tends to benefit professional
cyclists physically as much or more than
intense cycling
Correct Answer: B
B Inference
Find the answer choice supported by the passage.
A. No. This answer choice is too strong. The argument talks only about cycling, not about exercise in general. In addition, you can’t prove that in every instance the higher the pulse rate, the less psychological benefit produced. What if having a pulse rate of 60 percent of the recommended maximum pulse rate leads to greater benefits than having a pulse rate of 40 percent of the maximum?
B. Yes. The argument demonstrates a correlation between the mood of professional cyclists and how intense the cycling is. When the cycling is at 60 percent of the recommended maximum pulse rate for recreational bikers, the professional cyclists reported being less depressed and angry. Those cycling at 85 percent, on the other hand, reported feeling more depressed and angry.
C. No. This answer choice is too strong. You can’t prove anything about pulse rates higher than 85 percent so it is possible that something higher could also improve mood.
D. No. This answer choice is too strong. You can’t prove that physical factors contribute as much as psychological factors contribute. The passage does not include information about any psychological factors that may have been at play so you can’t make that comparison.
E. No. You can’t prove whether moderate cycling benefits professional cyclists physically as much or more than intense cycling.
LSAT Logical Reasoning Prep Test 52 Question #16 16. Anyone who believes in extraterrestrials believes in
UFOs. But the existence of UFOs has been
conclusively refuted. Therefore a belief in
extraterrestrials is false as well.
Which one of the following arguments contains
flawed reasoning most similar to that in the
argument above?
(A) Anyone who believes in unicorns believes in
centaurs. But it has been demonstrated that
there are no centaurs, so there are no
unicorns either.
(B) Anyone who believes in unicorns believes in
centaurs. But you do not believe in centaurs,
so you do not believe in unicorns either.
(C) Anyone who believes in unicorns believes in
centaurs. But you do not believe in unicorns,
so you do not believe in centaurs either.
(D) Anyone who believes in unicorns believes in
centaurs. But there is no good reason to
believe in centaurs, so a belief in unicorns is
unjustified as well.
(E) Anyone who believes in unicorns believes in
centaurs. But it has been conclusively proven
that there is no such thing as a unicorn, so a
belief in centaurs is mistaken as well.
Correct Answer: A
A Parallel Flaw
This argument is diagrammable: Believe in existence of ETs → believe in existence of UFOs. UFOs don’t exist → ETs don’t exist. The argument does not support the assumption that the existence of ETs depends on the existence of UFOs.
A. Yes. Believe in existence of unicorns → believe in existence of centaurs. Centaurs don’t exist → unicorns can’t exist. This is the same argument structure and the same flaw.
B. No. This argument is not flawed. Believe in unicorns → believe in centaurs. Don’t believe in centaurs → don’t believe in unicorns. The second conditional is the contrapositive of the first.
C. No. This answer choice does not make the switch from belief to actual existence.
D. No. This answer choice does not make the switch from belief to actual existence.
E. No. This answer choice does make the switch from belief to actual existence but its second premise starts with the non-existence of unicorns, which were, in fact, the sufficient condition in the first premise. This does not match the structure of the original argument.
LSAT Logical Reasoning Prep Test 52 Question #17 17. People want to be instantly and intuitively liked.
Those persons who are perceived as forming
opinions of others only after cautiously gathering
and weighing the evidence are generally resented.
Thus, it is imprudent to appear prudent.
Which one of the following, if assumed, enables the
argument’s conclusion to be properly drawn?
(A) People who act spontaneously are well liked.
(B) Imprudent people act instantly and intuitively.
(C) People resent those less prudent than
themselves.
(D) People who are intuitive know instantly when
they like someone.
(E) It is imprudent to cause people to resent you.
Correct Answer: E
E Suffiicient Assumption
The conclusion of the argument is that it is imprudent to appear prudent. The first premise is that people want to be instantly and intuitively liked. The second premise is that people who are perceived to form opinions about others non-spontaneously are generally resented. The argument shifts language from the premise, which discusses behavior that causes resentment, to the conclusion, which discusses prudence. You need an answer that proves the conclusion by tying it to resentment.
A. No. The conclusion isn’t about how people need to act in order to be well liked. It is a judgment about appearing prudent, not about spontaneity.
B. No. You need to know why it is imprudent to appear prudent, not how imprudent people generally act.
C. No. If anything, this argument seems to claim that people resent those more prudent than themselves.
D. No. The conclusion is concerned with prudence and imprudence, not about intuitive people.
E. Yes. This gives the argument the connection it needs between imprudence and resentment.
LSAT Logical Reasoning Prep Test 52 Question #18 18. Journalist: Recent studies have demonstrated that a
regular smoker who has just smoked a
cigarette will typically display significantly
better short-term memory skills than a
nonsmoker, whether or not the nonsmoker has
also just smoked a cigarette for the purposes of
the study. Moreover, the majority of those
smokers who exhibit this superiority in shortterm memory skills will do so for at least eight
hours after having last smoked.
If the journalist’s statements are true, then each of
the following could be true EXCEPT:
(A) The short-term memory skills exhibited by a
nonsmoker who has just smoked a cigarette
are usually substantially worse than the shortterm memory skills exhibited by a nonsmoker
who has not recently smoked a cigarette.
(B) The short-term memory skills exhibited by a
nonsmoker who has just smoked a cigarette
are typically superior to those exhibited by a
regular smoker who has just smoked a
cigarette.
(C) The short-term memory skills exhibited by a
nonsmoker who has just smoked a cigarette
are typically superior to those exhibited by a
regular smoker who has not smoked for more
than eight hours.
(D) A regular smoker who, immediately after
smoking a cigarette, exhibits short-term
memory skills no better than those typically
exhibited by a nonsmoker is nevertheless
likely to exhibit superior short-term memory
skills in the hours following a period of heavy
smoking.
(E) The short-term memory skills exhibited by a
regular smoker who last smoked a cigarette
five hours ago are typically superior to those
exhibited by a regular smoker who has just
smoked a cigarette.
Correct Answer: B
B Inference
Find the answer choice that contradicts evidence in the argument.
A. No. This answer choice could be true. The argument doesn’t compare the difference in memory between nonsmokers who have just smoked a cigarette and nonsmokers who haven’t recently smoked a cigarette.
B. Yes. The argument states that the short-term memory skills of a nonsmoker who has just smoked are typically significantly worse than those of a smoker who has just smoked. So, this answer choice directly contradicts the argument.
C. No. The argument doesn’t compare the memory skills of nonsmokers who have just smoked and smokers who haven’t smoked in over eight hours. This answer choice could be true.
D. No. This answer choice could be true. The argument doesn’t say anything about periods of heavy smoking. The answer choice is also comparing two individuals, not the typical results.
E. No. The argument doesn’t compare the memory skills of smokers who last smoked five hours ago and smokers who have just smoked. This answer choice could be true.
LSAT Logical Reasoning Prep Test 52 Question #19 19. Educator: It has been argued that our professional
organization should make decisions about
important issues—such as raising dues and
taking political stands—by a direct vote of all
members rather than by having members vote
for officers who in turn make the decisions.
This would not, however, be the right way to
decide these matters, for the vote of any given
individual is much more likely to determine
organizational policy by influencing the
election of an officer than by influencing the
result of a direct vote on a single issue.
Which one of the following principles would, if valid,
most help to justify the educator’s reasoning?
(A) No procedure for making organizational
decisions should allow one individual’s vote
to weigh more than that of another.
(B) Outcomes of organizational elections should
be evaluated according to their benefit to the
organization as a whole, not according to the
fairness of the methods by which they are
produced.
(C) Important issues facing organizations should
be decided by people who can devote their
full time to mastering the information
relevant to the issues.
(D) An officer of an organization should not make
a particular decision on an issue unless a
majority of the organization’s members
would approve of that decision.
(E) An organization’s procedures for making
organizational decisions should maximize the
power of each member of the org
Correct Answer: E
E Principle Strengthen
This argument is designed to disagree with a claim. The educator is against deciding matters in his professional organization by a direct vote instead of having matter decided by officers who are elected by direct vote. The premise is that organizational policy will be more influenced by individuals voting for officers rather than individuals directly voting on issues. A principle that would strengthen it would connect procedures for making organizational decisions with the amount of influence each member has on these decisions.
A. No. This principle would weaken the argument, if anything.
B. No. This principle does not connect the procedures for making decisions with the amount of influence of each member on these decisions.
C. No. This answer choice does not tell us that it would be the officers that would have this time, so it doesn’t help the argument.
D. No. This might be true but it does not strengthen the educator’s claim that voting to elect officers will give each individual more influence in organizational policy.
E. Yes. This principle strengthens the argument by relating procedures for making decisions and the maximization of the power of each individual to influence the decisions.
LSAT Logical Reasoning Prep Test 52 Question #20 20. Neural connections carrying signals from the cortex
(the brain region responsible for thought) down to
the amygdala (a brain region crucial for emotions)
are less well developed than connections carrying
signals from the amygdala up to the cortex. Thus, the
amygdala exerts a greater influence on the cortex
than vice versa.
The argument’s conclusion follows logically if which
one of the following is assumed?
(A) The influence that the amygdala exerts on the
rest of the brain is dependent on the influence
that the cortex exerts on the rest of the brain.
(B) No other brain region exerts more influence
on the cortex than does the amygdala.
(C) The region of the brain that has the most
influence on the cortex is the one that has the
most highly developed neural connections to
the cortex.
(D) The amygdala is not itself controlled by one or
more other regions of the brain.
(E) The degree of development of a set of neural
connections is directly proportional to the
influence transmitted across those
connections.
Correct Answer: E
E Sufficient Assumption
The conclusion of the argument is that the amygdala exerts a greater influence on the cortex than vice versa. The premise for this conclusion is that the neural connections that carry signals from the cortex to the amygdala are less well developed than the connections carrying signals the other way around. The argument equates how developed the connections carrying signals from one part of the brain to the other are to the amount of influence one part of the brain has on the other.
A. No. The argument is concerned only with the influence the amygdala exerts on the cortex, not the rest of the brain.
B. No. Other brain regions are not relevant and the assumption needs to equate how developed the connections are to the amount of influence.
C. No. This answer choice is too general. The region of the brain that has the most highly developed neural connections to the cortex might be something other than the amygdala.
D. No. The argument is concerned with the influence that the amygdala has on the cortex. It doesn’t matter whether some other region controls it.
E. Yes. This connects the degree of development of neural connections with the degree of influence one part of the brain has on another.
LSAT Logical Reasoning Prep Test 52 Question #21 21. The Iliad and the Odyssey were both attributed to
Homer in ancient times. But these two poems differ
greatly in tone and vocabulary and in certain details
of the fictional world they depict. So they are almost
certainly not the work of the same poet.
Which one of the following statements, if true, most
weakens the reasoning above?
(A) Several hymns that were also attributed to
Homer in ancient times differ more from the
Iliad in the respects mentioned than does the
Odyssey.
(B) Both the Iliad and the Odyssey have come
down to us in manuscripts that have suffered
from minor copying errors and other textual
corruptions.
(C) Works known to have been written by the
same modern writer are as different from
each other in the respects mentioned as are
the Iliad and the Odyssey.
(D) Neither the Iliad nor the Odyssey taken by
itself is completely consistent in all of the
respects mentioned.
(E) Both the Iliad and the Odyssey were the result
of an extended process of oral composition in
which many poets were involved.
Correct Answer: C
C Weaken
This argument disagrees with the claim that the difference in vocabulary, tone, and details of the fictional world depicted in the Iliad and the Odyssey imply that they could almost certainly not be the work of the same poet. A good answer choice will demonstrate how even if two works are different in many ways, the same person may have written both of them.
A. No. Homer might not have actually written the hymns either.
B. No. This doesn’t go far enough. If the manuscripts have suffered only minor copying errors and other textual corruptions, the corruptions won’t explain away all of the stylistic differences between the two.
C. Yes. You know that the modern writer actually wrote the works described. This counterexample lends plausibility to the possibility that Homer wrote both the Iliad and the Odyssey despite their many differences.
D. No. The argument rests on comparing the Iliad with the Odyssey, not looking at each by itself.
E. No. This would support the claim that Homer didn’t write both.
LSAT Logical Reasoning Prep Test 52 Question #22 22. Moralist: A statement is wholly truthful only if it is
true and made without intended deception. A
statement is a lie if it is intended to deceive or
if its speaker, upon learning that the statement
was misinterpreted, refrains from clarifying it.
Which one of the following judgments most closely
conforms to the principles stated by the moralist?
(A) Ted’s statement to the investigator that he had
been abducted by extraterrestrial beings was
wholly truthful even though no one has ever
been abducted by extraterrestrial beings.
After all, Ted was not trying to deceive the
investigator.
(B) Tony was not lying when he told his
granddaughter that he did not wear dentures,
for even though Tony meant to deceive his
granddaughter, she made it clear to Tony that
she did not believe him.
(C) Siobhan did not tell a lie when she told her
supervisor that she was ill and hence would
not be able to come to work for an important
presentation. However, even though her
statement was true, it was not wholly truthful.
(D) Walter’s claim to a potential employer that he
had done volunteer work was a lie. Even
though Walter had worked without pay in his
father’s factory, he used the phrase “volunteer
work” in an attempt to deceive the interviewer
into thinking he had worked for a socially
beneficial cause.
(E) The tour guide intended to deceive the tourists
when he told them that the cabin they were
looking at was centuries old. Still, his
statement about the cabin’s age was not a lie,
for if he thought that this statement had been
misinterpreted, he would have tried to
clarify it.
Correct Answer: D
D Principle Match
Diagram the moralist’s two principles. 1. Statement wholly truthful → it’s true and made without intended deception. Contrapositive: ~true or made with intended deception → ~not wholly truthful. 2. Intended to deceive or doesn’t clarify misinterpretation → lie. Contrapositive: ~lie → ~intended to deceive and clarifies misinterpretation. The best answer choice will provide an example in which at least one of the two principles is fulfilled.
A. No. Neither principle gives criteria to determine that a statement is wholly truthful.
B. No. Neither principle gives criteria to determine that a statement is not a lie, only when it is a lie.
C. No. You don’t know whether Siobhan intended to deceive, nor do you know whether she is actually sick. This doesn’t fit either principle.
D. Yes. If a statement is intended to deceive, it is a lie. Walter intended to deceive, so he lied.
E. No. If the statement is intended to deceive OR the person doesn’t clarify a misinterpretation, the statement is a lie. So the tour guide DID lie, according to the second principle.
LSAT Logical Reasoning Prep Test 52 Question #23 23. Principle: It is healthy for children to engage in an
activity that promotes their intellectual
development only if engaging in that activity
does not detract from their social
development.
Application: Although Megan’s frequent reading
stimulates her intellectually, it reduces the
amount of time she spends interacting with
other people. Therefore, it is not healthy for
her to read as much as she does.
The application of the principle is most vulnerable to
criticism on which one of the following grounds?
(A) It misinterprets the principle as a universal
claim intended to hold in all cases without
exception, rather than as a mere
generalization.
(B) It overlooks the possibility that the benefits of
a given activity may sometimes be important
enough to outweigh the adverse health effects.
(C) It misinterprets the principle to be, at least in
part, a claim about what is unhealthy, rather
than solely a claim about what is healthy.
(D) It takes for granted that any decrease in the
amount of time a child spends interacting
with others detracts from that child’s social
development.
(E) It takes a necessary condition for an activity’s
being healthy as a sufficient condition for its
being so.
Correct Answer: D
D Principle Match
This argument contains a principle that states the following: healthy to engage in intellectual development → engaging in that activity does not detract from social development. The argument then presents an application in the evidence about Megan. It draws the conclusion that Megan’s amount of reading is not healthy because it reduces the amount of time she spends interacting with other people. The flaw is that the argument equates interacting with others with social development.
A. No. The principle is a universal claim.
B. No. The argument does not discuss health effects.
C. No. As the principle is a conditional statement, it has a contrapositive. The contrapositive does make a claim about what is unhealthy.
D. Yes. The argument equates interacting with other people and social development. It might well be that the plot lines in the books that she reads help with her social development.
E. No. This argument does not contain a necessary/sufficient flaw.
LSAT Logical Reasoning Prep Test 52 Question #24 In response to several bacterial infections traced to
its apple juice, McElligott now flash pasteurizes its
apple juice by quickly heating and immediately
rechilling it. Intensive pasteurization, in which juice
is heated for an hour, eliminates bacteria more
effectively than does any other method, but is likely
to destroy the original flavor. However, because
McElligott’s citrus juices have not been linked to any
bacterial infections, they remain unpasteurized.
The statements above, if true, provide the most
support for which one of the following claims?
(A) McElligott’s citrus juices contain fewer
infectious bacteria than do citrus juices
produced by other companies.
(B) McElligott’s apple juice is less likely to contain
infectious bacteria than are McElligott’s citrus
juices.
(C) McElligott’s citrus juices retain more of the
juices’ original flavor than do any pasteurized
citrus juices.
(D) The most effective method for eliminating
bacteria from juice is also the method most
likely to destroy flavor.
(E) Apple juice that undergoes intensive
pasteurization is less likely than McElligott’s
apple juice is to contain bacteria.
Correct Answer: E
E Inference
Find the answer choice supported by the passage.
A. No. The passage does not provide information about the amount of bacteria in other companies’ juices.
B. No. The passage doesn’t have any comparison between the amounts of bacteria in the apple juice versus the citrus juices. You can’t prove which juice is less likely to contain infectious bacteria.
C. No. Intensive pasteurization is likely to destroy the original flavor, but whether other types of pasteurization do this is not discussed in the passage. So there is not enough information to determine whether McElligott’s unpasteurized citrus juices retain more of the original flavor than do any pasteurized citrus juices.
D. No. This answer choice sounds good but is too strong. Intensive pasteurization is the most effective method for eliminating bacteria from juice. Intensive pasteurization is also likely to destroy the original flavor of the juice. The passage does not support, however, that intensive pasteurization is the method most likely to destroy flavor. Another method of eliminating bacteria might be even more likely to destroy the flavor.
E. Yes. McElligott’s juice did not undergo intensive pasteurization because it was flash pasteurized. It is also stated that intensive pasteurization is the most effective way to eliminate bacteria from the juice, so a juice that undergoes intensive pasteurization is less likely to contain bacteria than McElligott’s apple juice.
LSAT Logical Reasoning Prep Test 52 Question #25 25. Sociologist: Widespread acceptance of the idea that
individuals are incapable of looking after their
own welfare is injurious to a democracy. So
legislators who value democracy should not
propose any law prohibiting behavior that is
not harmful to anyone besides the person
engaging in it. After all, the assumptions that
appear to guide legislators will often become
widely accepted.
The sociologist’s argument requires the assumption
that
(A) democratically elected legislators invariably
have favorable attitudes toward the
preservation of democracy
(B) people tend to believe what is believed by
those who are prominent and powerful
(C) legislators often seem to be guided by the
assumption that individuals are incapable of
looking after their own welfare, even though
these legislators also seem to value democracy
(D) in most cases, behavior that is harmful to the
person who engages in it is harmful to no one
else
(E) a legislator proposing a law prohibiting an act
that can harm only the person performing the
act will seem to be assuming that individuals
are incapable of looking after their own
welfare
Correct Answer: E
E Necessary Assumption
The sociologist is solving a problem. The problem is that widespread acceptance of the idea that individuals are incapable of looking after their own welfare is injurious to a democracy. The sociologist concludes that legislators who value democracy should not propose any law that prohibits behavior harmful only to the person engaging in that behavior. The premise is that the assumptions that appear to guide legislators will often become widely accepted. There is a gap between discouraging the proposal of laws prohibiting actions harmful only to the person engaging in them and the assumptions that appear to guide these legislators. For the argument to work, the assumptions that appear to guide the legislators must involve the idea that individuals are incapable of looking after themselves.
A. No. The argument explicitly discusses legislators who value democracy, not all democratically elected legislators.
B. No. The sociologist doesn’t care about what the legislators actually believe about whether people are capable of looking after themselves. He/she is concerned with what the legislators appear to believe about this subject.
C. No. This is a description of how legislators often seem to be guided. The argument is a prescription for how legislators who value democracy often seem to be guided.
D. No. This might be true. However, it doesn’t give you the connection you need between what laws legislators should propose and what their underlying assumptions appear to be.
E. Yes. This connects the sociologist’s prescription for proposing laws and the perceived assumptions of the legislators.
LSAT PrepTest 52 Section #3 Question #1. Any museum that owns the rare stamp that features
an airplane printed upside down should not display
it. Ultraviolet light causes red ink to fade, and a
substantial portion of the stamp is red. If the stamp
is displayed, it will be damaged. It should be kept
safely locked away, even though this will deny the
public the chance to see it.
The reasoning above most closely conforms to which
one of the following principles?
(A) The public should judge the quality of a
museum by the rarity of the objects in its
collection.
(B) Museum display cases should protect their
contents from damage caused by ultraviolet
light.
(C) Red ink should not be used on items that will
not be exposed to ultraviolet light.
(D) A museum piece that would be damaged by
display should not be displayed.
(E) The primary purpose of a museum is to
educate the public.
Correct Answer: D
D Principle Match
The passage claims that any museum that owns the rare stamp that features an airplane printed upside down should not display it. This is because a substantial portion of the stamp is red, and ultraviolet light causes red ink to fade. The most important criterion for the conclusion seems to be that if the stamp is displayed, it will be damaged. The author acknowledges that the public will be denied the chance to see the stamp but maintains that the stamp ought to be kept safely locked away.
A. No. The passage does not mention whether the rare objects that a museum possesses should be displayed or not.
B. No. The passage states that if the stamp is displayed, it will be damaged. So, the stamp shouldn’t be displayed. It doesn’t address what features the museum display cases should have.
C. No. Red ink WAS used on this stamp and the stamp WILL be exposed to ultraviolet light if displayed. This principle doesn’t apply.
D. Yes. According to the passage, the stamp would be damaged by display and, therefore, should not be displayed.
E. No. If the primary purpose of a museum is to educate the public, it might be thought that the stamp should be displayed. Yet the passage states that it shouldn’t be, as it would be damaged.
LSAT PrepTest 52 Section #3 Question #2 Dietitian: Many diet-conscious consumers are excited
about new “fake fat” products designed to give
food the flavor and consistency of fatty foods,
yet without fat’s harmful effects. Consumers
who expect the new fat substitute to help them
lose weight arc likely to be disappointed,
however. Research has shown that when people
knowingly or unknowingly eat foods
containing “fake fat,” they tend to take in at
least as many additional calories as are saved
by eating “fake fat.”
Which one of the following most accurately expresses
the conclusion of the dietitian’s argument?
(A) People tend to take in a certain number of
daily calories, no matter what types of food
they eat
(B) Most consumers who think that foods with
“fake fat” are more nutritious than fatty foods
are destined to be disappointed.
(C) “Fake fat” products are likely to contribute to
obesity more than do other foods.
(D) “Fake fat” in foods is probably not going to
help consumers meet weight loss goals.
(E) “Fake fat” in foods is indistinguishable from
genuine fat by most consumers on the basis of
taste alone.
Correct Answer: D
D Main Point
The dietician warns that consumers who see a solution to their weight-loss problems in “fake fat” products are likely to be disappointed. This is because the people who either knowingly or unknowingly eat foods containing “fake fat” tend to take in at least as many additional calories as are saved by eating “fake fat” by eating more of the food.
A. No. This is too general. The dietician does not talk about the number of calories people consume, no matter what type of food they eat. The dietician is concerned primarily with fatty foods and their “fake fat” alternatives.
B. No. The dietician addresses only the number of calories consumed, not overall nutrition.
C. No. This is too strong. The dietician claims only that “fake fat” products are unlikely to help in weight loss, not that they will be more likely to contribute to obesity.
D. Yes. Since consumers of “fake fat” products tend to take in at least as many additional calories as are saved when eating these foods, it is unlikely that these foods will help them lose weight.
E. No. The dietician explains that “fake fat” products are designed to give food the flavor and consistency of fatty foods, but the dietician doesn’t explain whether or not they are successful in doing so.
LSAT PrepTest 52 Section #3 Question #3 Banking analyst: Banks often offer various services to
new customers at no charge. But this is not an
ideal business practice, since regular, long-term
customers, who make up the bulk of the
business for most banks, are excluded from
these special offers.
Which one of the following, if true, most strengthens
the banking analyst’s argument’?
(A) Most banks have similar charges for most
services and pay similar interest rates on
deposits.
(B) Banks do best when offering special privileges
only to their most loyal customers.
(C) Offering services at no charge to all of its
current customers would be prohibitively
expensive for a bank.
(D) Once they have chosen a bank, people tend to
remain loyal to that bank.
(E) Some banks that offer services at no charge to
new customers are very successful.
Correct Answer: B
B Strengthen
The banking analyst concludes that offering no-charge services to new customers is not an ideal business practice. The premise is that regular, long-term customers are excluded from these special offers and it is these customers who make up the bulk of business for most banks.
A. No. This argument is claiming that a no-fee service for new customers is not an ideal business practice. It does not discuss how much the banks charge for the services, normally.
B. Yes. If this is true, banks would do better to give their best offers and services to their long-term customers instead of focusing on new customers.
C. No. The banking analyst discourages offering no-fee services to new customers but does not discuss what banks should do instead.
D. No. If this were true, it would weaken the conclusion.
E. No. If this were true, it would weaken the conclusion.
LSAT PrepTest 52 Section #3 Question #4 Panelist: Medical research articles cited in popular
newspapers or magazines are more likely than
other medical research articles to be cited in
subsequent medical research. Thus, it appears
that medical researchers’ judgments of the
importance of prior research are strongly
influenced by the publicity received by that
research and do not strongly correspond to the
research’s true importance.
The panelist’s argument is most vulnerable to
criticism on the grounds that it
(A) presents counterarguments to a view that is
not actually held by any medical researcher
(B) fails to consider the possibility that popular
newspapers and magazines do a good job of
identifying the most important medical
research articles
(C) takes for granted that coverage of medical
research in the popular press is more
concerned with the eminence of the scientists
involved than with the content of their
research
(D) fails to consider the possibility that popular
newspapers and magazines are able to review
only a minuscule percentage of medical
research articles
(E) draws a conclusion that is logically equivalent
to its premise
Correct Answer: B
B Flaw
The panelist concludes that medical researchers’ judgments of the importance of prior research are strongly influenced by the research appearing in popular magazines and newspapers, and, therefore, the judgments do not strongly correspond to the research’s true importance. The premise is that medical research that is cited in popular magazines or newspapers is more likely to be cited in later medical research. The panelist fails to consider that there might be a good reason, common to both the citations in popular media and to later medical research, that these medical research articles are cited. Maybe it’s the most cutting edge and important medical research that gets cited in popular media, for example.
A. No. There is no view cited in the premises.
B. Yes. This would demonstrate that both the later medical research and the popular media have a good reason to cite this research.
C. No. The argument doesn’t talk about how esteemed or well-known the scientists are who completed the medical research that was cited in popular media.
D. No. The problem isn’t the percentage of medical research articles that the popular media are able to review; it is that the panelist doesn’t see that there might be a good reason that both the popular media and the later medical research are likely to cite the same research.
E. No. This is not a circular argument.
LSAT PrepTest 52 Section #3 Question #5 Lahar: We must now settle on a procedure for
deciding on meeting agendas. Our club’s
constitution allows three options: unanimous
consent, majority vote, or assigning the task to
a committee. Unanimous consent is unlikely.
Forming a committee has usually led to
factionalism and secret deals. Clearly, we
should subject meeting agendas to majority
vote.
Lahar’s argument does which one of the following?
(A) rejects suggested procedures on constitutional
grounds
(B) claims that one procedure is the appropriate
method for reaching every decision in the
club
(C) suggests a change to a constitution on the basis
of practical considerations
(D) recommends a choice based on the elimination
of alternative options
(E) supports one preference by arguing against
those who have advocated alternatives
Correct Answer: D
D Reasoning
Lahar concludes that his club should subject meeting agendas to majority vote. He does this through process of elimination. The club’s constitution allows three ways to decide on meeting agendas. Lahar claims that unanimous consent is unlikely and that forming a committee to decide this has usually led to groups of people pitted against each other and secret deals. The best option, then, is the one that remains: majority vote.
A. No. Lahar considers only the options that are allowed under the club’s constitution.
B. No. This is almost right. However, it’s not the credited response because the answer choice is too strong. He claims that one procedure is the appropriate method for reaching decisions on meeting agendas, not for reaching every decision.
C. No. Lahar does acknowledge practical considerations. However, he does not suggest a change to the constitution.
D. Yes. Lahar eliminates the other two options, leaving only the one that he recommends.
E. No. Lahar argues against alternatives but he does not argue against the people who have advocated alternatives.
LSAT PrepTest 52 Section #3 Question #6 Mayor: Local antitobacco activists are calling for
expanded antismoking education programs
paid for by revenue from heavily increased
taxes on cigarettes sold in the city. Although
the effectiveness of such education programs is
debatable, there is strong evidence that the
taxes themselves would produce the soughtafter reduction in smoking. Surveys show that
cigarette sales drop substantially in cities that
impose stiff tax increases on cigarettes.
Which one of the following, if true, most undermines
the reasoning in the argument above?
(A) A city-imposed tax on cigarettes will
substantially reduce the amount of smoking
in the city if the tax is burdensome to the
average cigarette consumer.
(B) Consumers are more likely to continue buying
a product if its price increases due to higher
taxes than if its price increases for some other
reason.
(C) Usually, cigarette sales will increase
substantially in the areas surrounding a city
after that city imposes stiff taxes on cigarettes.
(D) People who are well informed about the effects
of long-term tobacco use are significantly less
likely to smoke than are people who are not
informed.
(E) Antismoking education programs that are
funded by taxes on cigarettes will tend to lose
their funding if they are successful.
Correct Answer: C
C Weaken
This argument is designed to disagree with a position. The mayor disagrees with local activists calling for expanded antismoking educations programs, which would be paid for by revenue from greatly increased taxes on cigarettes sold in the city. The mayor thinks that these programs are unnecessary, as there is strong evidence that the taxes by themselves would produce the reduction in smoking that the antitobacco activists are seeking. He bases his conclusion on surveys showing that cigarette sales drop substantially in cities that impose these high tax increases on cigarettes.
A. No. This strengthens the argument because it makes a link between high taxes and substantially reduced smoking.
B. No. Consumers might be more likely to continue buying cigarettes if the price increase is due to higher taxes, but as long as less people actually buy and smoke the cigarettes, the mayor’s argument might still be valid.
C. Yes. If people are buying a lot more cigarettes outside of the city, the rate of smoking in that city might not decrease substantially. This answer choice exploits the language shift from cigarette sales to smoking rates.
D. No. This does not address the tax increase issue that is the crux of the mayor’s argument.
E. No. This does not address the mayor’s argument.
LSAT PrepTest 52 Section #3 Question #8 Caldwell: The government recently demolished a
former naval base. Among the complex’s
facilities were a gymnasium, a swimming pool,
office buildings, gardens, and housing for
hundreds of people. Of course the government
was legally permitted to use these facilities as it
wished. But clearly, using them for the good of
the community would have benefited
everyone, and thus the government’s actions
were not only inefficient but immoral.
Caldwell’s argument is most vulnerable to criticism
on the grounds that it
(A) fails to consider that an action may be morally
permissible even if an alternative course of
action is to everyone’s advantage
(B) presumes, without providing justification, that
the actual consequences of an action are
irrelevant to the action’s moral permissibility
(C) presumes, without providing justification, that
the government never acts in the most
efficient manner
(D) presumes, without providing justification, that
any action that is efficient is also moral
(E) inappropriately treats two possible courses of
action as if they were the only options
Correct Answer: A
A Flaw
Caldwell concludes that the government’s actions in tearing down a former naval base were not only inefficient but also immoral. Caldwell concludes this because the former naval base had a large number of facilities, such as a swimming pool, housing, etc., that might have been used for the good of the community, benefitting everyone. Thus, Caldwell equates what is moral with benefiting everyone.
A. Yes. Caldwell doesn’t allow for the possibility that the action of tearing down the base might still be morally permissible even if it doesn’t benefit everyone.
B. No. In fact, Caldwell thinks that the actual consequences are incredibly important to the action’s moral permissibility.
C. No. This is too strong. Caldwell is talking about the demolition of a single base, not the actions of the government in general.
D. No. This one is close. However, Caldwell says that the action was not only inefficient but also immoral. Caldwell isn’t equating being inefficient with being immoral. So Caldwell is also not presuming that any efficient action is also moral.
E. No. This one is tempting, as well. However, Caldwell doesn’t ever claim that tearing down the base or using it for the community are the only options. Other courses of action don’t happen to be relevant to Caldwell’s point.
LSAT PrepTest 52 Section #3 Question #7 Gotera: Infants lack the motor ability required to
voluntarily produce particular sounds, but
produce various babbling sounds randomly.
Most children are several years old before they
can voluntarily produce most of the vowel and
consonant sounds of their language. We can
conclude that speech acquisition is entirely a
motor control process rather than a process
that is abstract or mental.
Which one of the following is an assumption
required by Gotera’s argument?
(A) Speech acquisition is a function only of one’s
ability to produce the sounds of spoken
language.
(B) During the entire initial babbling stage, infants
cannot intentionally move their tongues while
they are babbling.
(C) The initial babbling stage is completed during
infancy.
(D) The initial babbling stage is the first stage of
the speech acquisition process.
(E) Control of tongue and mouth movements
requires a sophisticated level of mental
development.
Correct Answer: A
A Necessary Assumption
Gotera concludes that speech acquisition is entirely a motor control process, not one that is abstract or mental. Gotera bases this conclusion on two facts about infants and children. Infants don’t have the motor control required to voluntarily produce particular sounds. Instead, they produce random babbling sounds. Most children cannot voluntarily produce most of the vowel and consonant sounds of their language until they are several years old. Therefore, if children can’t voluntarily produce the sounds of their language, they can’t really talk. However, that doesn’t mean that motor control is the only process involved in speech acquisition. The conclusion is too strong for the evidence that supports it, so it requires an assumption to fill in the gap.
A. Yes. This eliminates the possibility that there might be some additional process that affects speech acquisition that does not involve motor control. This closes the gap.
B. No. It wouldn’t matter if infants could intentionally move their tongues, as long as they lack the motor ability to intentionally produce particular sounds. The evidence states that they do lack this ability.
C. No. It wouldn’t matter if children babbled until they were 7, as long as they also developed the motor abilities discussed in the argument.
D. No. This might be true. However, it doesn’t address the gap between the evidence and the claim that speech acquisition is entirely a motor control process.
E. No. This would weaken the argument. If this were true, then mental development would factor in to speech acquisition, against Gotera’s argument.
LSAT PrepTest 52 Section #3 Question #9 Reducing stress lessens a person’s sensitivity to pain.
This is the conclusion reached by researchers who
played extended audiotapes to patients before they
underwent surgery and afterward while they were
recovering. One tape consisted of conversation; the
other consisted of music. Those who listened only to
the latter tape required less anesthesia during surgery
and fewer painkillers afterward than those who
listened only to the former tape.
Which one of the following is an assumption on
which the researchers’ reasoning depends?
(A) All of the patients in the study listened to the
same tape before surgery as they listened to
after surgery.
(B) Anticipating surgery is no less stressful than
recovering from surgery.
(C) Listening to music reduces stress.
(D) The psychological effects of music are not
changed by anesthesia or painkillers.
(E) Both anesthesia and painkillers tend to reduce
stress.
Correct Answer: C
C Necessary Assumption
The researchers concluded that reducing stress lessens a person’s sensitivity to pain, based on an experiment where they played audiotapes to patients before and after surgery. The patients who listened only to music required less anesthesia and fewer painkillers as compared to the patients who listened only to conversation. The gap is between reducing stress and music. The music might have caused the patients to require less anesthesia and fewer painkillers for some other reason than because the music reduced stress.
A. No. It is not essential that the patients listened to the same tape before and after surgery, as long as one group listened to conversation and the other group listened to music.
B. No. This is not essential to the argument.
C. Yes. This makes the connection between music and stress reduction. It eliminates other possible reasons as to why the patients listening to music might have required less anesthesia and fewer painkillers.
D. No. This is not essential to the argument.
E. No. This might be true, but it doesn’t give us the connection between music and reducing stress that the argument requires.
LSAT PrepTest 52 Section #3 Question #10 Samuel: Because communication via computer is
usually conducted privately and anonymously
between people who would otherwise interact in
person, it contributes to the dissolution, not the
creation, of lasting communal bonds.
Tova: You assume that communication via computer
replaces more intimate forms of communication
and interaction, when more often it replaces
asocial or even antisocial behavior.
On the basis of their statements, Samuel and Tova
are committed to disagreeing about which one of the
following?
(A) A general trend of modern life is to dissolve
the social bonds that formerly connected
people.
(B) All purely private behavior contributes to the
dissolution of social bonds.
(C) Face-to-face communication is more likely to
contribute to the creation of social bonds
than is anonymous communication.
(D) It is desirable that new social bonds be created
to replace the ones that have dissolved.
(E) If people were not communicating via
computer, they would most likely be engaged
in activities that create stronger social bonds.
Correct Answer: E
E Point at Issue
Samuel concludes that communication via computer contributes to the dissolution of lasting communal bonds. His premise is that communication via computer is usually conducted privately and anonymously between people who would otherwise have conducted the communication in person. Tova disagrees with Samuel’s conclusion because she disagrees with his claim that communication via computer replaces other forms of interaction and communication. She claims, instead, that it replaces asocial or antisocial behavior.
A. No. Neither discusses the dissolution of social bonds as a general trend of modern life.
B. No. This is too strong. Neither talks about all purely private behavior. They are talking about a specific private behavior: communication via computer.
C. No. Tova doesn’t discuss whether face-to-face communication is more likely to contribute to the creation of social bonds.
D. No. Tova doesn’t discuss whether it is desirable to replace social bonds that have dissolved with new ones.
E. Yes. Samuel thinks that communicating via computer replaces social behavior, whereas Tova thinks that communicating via computer doesn’t because it replaces asocial/antisocial behavior.
LSAT PrepTest 52 Section #3 Question #11 Spreading iron particles over the surface of the
earth’s oceans would lead to an increase in
phytoplankton, decreasing the amount of carbon
dioxide in the atmosphere and thereby counteracting
the greenhouse effect. But while counteracting the
greenhouse effect is important, the side effects of an
iron-seeding strategy have yet to be studied. Since the
oceans represent such an important resource, this
response to the greenhouse effect should not be
implemented immediately.
The reasoning above most closely conforms to which
one of the following principles?
(A) A problem-solving strategy should be
implemented if the side effects of the strategy
are known.
(B) Implementing a problem-solving strategy that
alters an important resource is impermissible
if the consequences are not adequately
understood.
(C) We should not implement a problem-solving
strategy if the consequences of doing so are
more serious than the problem itself.
(D) We should not implement a problem-solving
strategy if that strategy requires altering an
important resource.
(E) As long as there is a possibility that a strategy
for solving a problem may instead exacerbate
that problem, such a solution should not be
adopted.
Correct Answer: B
B Principle Match
The passage concludes that we should not immediately spread iron particles over the surface of the ocean in response to the greenhouse effect. Spreading the iron particles would counteract the greenhouse effect by increasing the number of phytoplankton, which would, in turn, decrease the amount of carbon dioxide in the atmosphere. However, the side effects of this strategy haven’t been studied yet, so the author of the argument thinks we should hold off on messing with such an important resource as the ocean.
A. No. The passage doesn’t address strategies with known side effects.
B. Yes. According to the passage, the iron-seeding strategy should not be used yet because the consequences to the ocean, an important resource, are unknown.
C. No. The passage states that the consequences of the iron-seeding strategy are not known, so there is no way to know if those consequences are more serious than the problem of the greenhouse effect.
D. No. This is close, but it states that we should not implement a strategy if it requires altering an important resource. The passage doesn’t go that far. It just says that research into the side effects should be done before implementing the strategy.
E. No. The passage doesn’t concern itself with whether the iron-seeding strategy has a possibility of exacerbating the greenhouse effect. The worry is in how this strategy might alter the oceans.
LSAT PrepTest 52 Section #3 Question #12 No matter how conscientious they are, historians
always have biases that affect their work. Hence,
rather than trying to interpret historical events,
historians should instead interpret what the people
who participated in historical events thought about
those events.
The reasoning in the argument is most vulnerable to
criticism on the grounds that the argument fails to
consider the possibility that
(A) historians who have different biases often
agree about many aspects of some historical
events
(B) scholars in disciplines other than history also
risk having their biases affect their work
(C) many of the ways in which historians’ biases
affect their work have been identified
(D) not all historians are aware of the effect that
their particular biases have on their work
(E) the proposed shift in focus is unlikely to
eliminate the effect that historians’ biases
have on their work
Correct Answer: E
E Flaw
The problem that this argument tries to solve is that historians always have biases that affect their work, which is the interpretation of historical events. The solution that is proposed is that historians should instead interpret what the people who participated in historical events thought about those events. The flaw is that the solution still requires an interpretation that is susceptible to bias.
A. No. This might be true. However, the important point is that historians have biases that affect their work, which is what the proposal claims to avoid.
B. No. Scholars in other disciplines are not relevant to the flaw of this argument.
C. No. The argument is trying to eliminate the biases. It doesn’t matter whether or not these biases have been identified.
D. No. It doesn’t matter, for the purposes of this argument, whether the historians are aware of the effect of their biases. The argument proposes a solution to eliminate the biases whether the historians are aware of them or not.
E. Yes. If historians still have to interpret what the participants thought about the events, there is still the possibility of biased interpretations.
LSAT PrepTest 52 Section #3 Question #13 Humanitarian considerations aside, sheer economics
dictates that country X should institute, as country Y
has done, a nationwide system of air and ground
transportation for conveying seriously injured
persons to specialized trauma centers. Timely access
to the kind of medical care that only specialized
centers can provide could save the lives of many
people. The earnings of these people would result in
a substantial increase in country X’s gross national
product, and the taxes paid on those earnings would
substantially augment government revenues.
The argument depends on the assumption that
(A) lifetime per-capita income is roughly the same
in country X as it is in country Y
(B) there are no specialized trauma centers in
country X at present
(C) the treatment of seriously injured persons in
trauma centers is not more costly than
treatment elsewhere
(D) there would be a net increase in employment
in country X if more persons survived serious
injury
(E) most people seriously injured in automobile
accidents in country X do not now receive
treatment in specialized trauma centers
Correct Answer: D
D Necessary Assumption
The argument concludes that economic considerations dictate that country X should institute a nationwide system of air and ground transportation for conveying the seriously injured to specialized trauma centers. The evidence presented for this conclusion is that timely access to the medical care that can be provided only at trauma centers will save many people’s lives. These people, who are alive as a result of timely access to trauma centers, would be earning money. That these people are earning money is a twofold benefit to country X: The earnings would result in a large increase in X’s GNP, and taxes paid on the earnings would greatly augment government revenues. The argument shifts language from people’s lives being saved to the total increase in X’s GNP and tax revenues. An increase in X’s GNP and tax revenues would require that, as a result of saving these people’s lives, there would be more people working in country X than there are right now. If not, the added cost of instituting the nationwide system might not be economically beneficial.
A. No. Country Y is irrelevant. The argument concentrates on country X.
B. No. The argument is concerned with making sure that people have timely access to specialized trauma centers, wherever they may be located.
C. No. It could be more costly, and yet the people would be alive and working, which would increase country X’s GNP.
D. Yes. The argument assumes that if more people survived serious injury, they would be adding to the workforce, thereby boosting country X’s GNP. If the survivors weren’t able to work, or if they replaced other people when they went back to work, the GNP wouldn’t increase and neither would tax revenue.
E. No. The issue is whether country X should enable people to get timely treatment in specialized trauma centers, not whether more people should go to specialized trauma centers.
LSAT PrepTest 52 Section #3 Question #14 Early urban societies could not have been
maintained without large-scale farming nearby. This
is because other methods of food acquisition, such as
foraging, cannot support populations as dense as
urban ones. Large-scale farming requires irrigation,
which remained unfeasible in areas far from rivers or
lakes until more recent times.
Which one of the following is most strongly
supported by the information above?
(A) Most peoples who lived in early times lived in
areas near rivers or lakes.
(B) Only if farming is possible in the absence of
irrigation can societies be maintained in areas
far from rivers or lakes.
(C) In early times it was not possible to maintain
urban societies in areas far from rivers or
lakes.
(D) Urban societies with farms near rivers or lakes
do not have to rely upon irrigation to meet
their farming needs.
(E) Early rural societies relied more on foraging
than on agriculture for food.
Correct Answer: C
C Inference
Early urban societies → large-scale farming nearby → irrigation → rivers or lakes. The contrapositive is as follows: ~rivers and ~lakes → ~irrigation → ~large-scale farming → ~early urban society.
A. No. The passage talks about early urban societies, but does not say how many peoples lived in them.
B. No. This answer choice can be diagrammed as follows: societies far from rivers or lakes → farming possible in the absence of irrigation. The passage talks only about early urban societies. Also, it doesn’t talk about the possibility of farming without irrigation.
C. Yes. See the contrapositive in the explanation above.
D. No. Even though the passage does not say that urban societies with farms near rivers or lakes necessarily rely upon irrigation, it doesn’t say that they don’t.
E. No. The passage doesn’t mention early rural societies.
LSAT PrepTest 52 Section #3 Question #15 Economist: A country’s rapid emergence from an
economic recession requires substantial new
investment in that country’s economy. Since
people’s confidence in the economic policies of
their country is a precondition for any new
investment, countries that put collective goals
before individuals’ goals cannot emerge
quickly from an economic recession.
Which one of the following, if assumed, enables the
economist’s conclusion to be properly drawn?
(A) No new investment occurs in any country that
does not emerge quickly from an economic
recession.
(B) Recessions in countries that put collective
goals before individuals’ goals tend not to
affect the country’s people’s support for their
government’s policies.
(C) If the people in a country that puts
individuals’ goals first are willing to make
new investments in their country’s economy,
their country will emerge quickly from an
economic recession.
(D) People in countries that put collective goals
before individuals’ goals lack confidence in
the economic policies of their countries.
(E) A country’s economic policies are the most
significant factor determining whether that
country’s economy will experience a
recession.
Correct Answer: D
D Sufficient Assumption
The economist concludes that countries that put collective goals before individual goals cannot emerge quickly from an economic recession because people’s confidence in the economic policies of their country is a precondition for any new investment. This new investment is important because substantial new investment in that country’s economy is required for a country’s rapid emergence from an economic recession. The gap in the argument is between people’s confidence in a country’s economic policies and whether the country puts collective goals before individuals’ goals.
A. No. This is too strong. There might be some new investment, yet a country might still not emerge quickly from a recession. Emerging quickly from an economic recession requires substantial new investment.
B. No. The economist doesn’t discuss whether the recessions themselves affect people’s support for their government’s policies. Also, this answer choice is talking about the government’s policies in general, while the argument focuses on economic policies.
C. No. The economist never claims what would be sufficient for a country to emerge quickly from an economic recession. The economist, instead, tells us that substantial new investments are necessary for a country to emerge from an economic recession and that countries that put collective goals first will fail this necessary condition.
D. Yes. This connects people’s confidence, or lack thereof, in their country’s economic policies and whether the country puts collective goals before individuals’ goals.
E. No. The economist is concerned only with countries that have experienced a recession, not whether they are more likely to experience a recession.
LSAT PrepTest 52 Section #3 Question #16 The average length of stay for patients at Edgewater
Hospital is four days, compared to six days at
University Hospital. Since studies show that recovery
rates at the two hospitals are similar for patients with
similar illnesses, University Hospital could decrease
its average length of stay without affecting quality of
care.
The reasoning in the argument is most vulnerable to
criticism on the grounds that the argument
(A) equates the quality of care at a hospital with
patients’ average length of stay
(B) treats a condition that will ensure the
preservation of quality of care as a condition
that is required to preserve quality of care
(C) fails to take into account the possibility that
patients at Edgewater Hospital tend to be
treated for different illnesses than patients at
University Hospital
(D) presumes, without providing justification, that
the length of time patients stay in the hospital
is never relevant to the recovery rates of these
patients
(E) fails to take into account the possibility that
patients at University Hospital generally
prefer longer hospital stays
Correct Answer: C
C Flaw
The argument concludes that University Hospital could decrease its average length of stay without affecting quality of care. This conclusion is based on a comparison between the average length of stay for patients at Edgewater Hospital and at University Hospital. Studies show that recovery rates for both are similar for patients with similar illnesses. The argument is problematic because similar recovery rates for patients with similar illnesses at these hospitals does not mean that most patients at both hospitals have similar illnesses. University Hospital might specialize in heart attack patients, while Edgewater might specialize in minor injuries and ailments, for example.
A. No. The argument does not say that quality of care and length of stay are the same thing. Based on the evidence concerning recovery rates at both hospitals, it claims that length of stay can be reduced without affecting the quality of care.
B. No. Wrong flaw. This argument does not confuse something sufficient with something necessary.
C. Yes. If the patients at Edgewater tend to be treated for different illnesses, then the recovery rate information does not support the claim that the average length of stay could be reduced.
D. No. The argument allows for the idea that length of stay might be relevant to recovery rates.
E. No. The connection is between average length of stay, recovery rates, and quality of care. Patients’ preferences are irrelevant.
LSAT PrepTest 52 Section #3 Question #17 Philosopher: Graham argues that since a person is
truly happy only when doing something, the
best life is a life that is full of activity. But we
should not be persuaded by Graham’s
argument. People sleep, and at least sometimes
when sleeping, they are truly happy, even
though they are not doing anything.
Which one of the following most accurately describes
the role played in the philosopher’s argument by the
claim that at least sometimes when sleeping, people
are truly happy, even though they are not doing
anything?
(A) It is a premise of Graham’s argument.
(B) It is an example intended to show that a
premise of Graham’s argument is false.
(C) It is an analogy appealed to by Graham but
that the philosopher rejects.
(D) It is an example intended to disprove the
conclusion of Graham’s argument.
(E) It is the main conclusion of the philosopher’s
argument.
Correct Answer: B
B Reasoning
The philosopher disagrees with Graham’s position that the best life is a life that is full of activity because a person is truly happy only when doing something. The philosopher gives the example of people sleeping, during which they are not doing anything but are sometimes truly happy. The role of the example is to speak against Graham’s reason for his conclusion by undermining the claim that a person is truly happy only when doing something.
A. No. It is a premise of the philosopher’s argument.
B. Yes. If the statement is true, Graham cannot claim, as support for his conclusion, that a person is truly happy only when doing something.
C. No. It is not part of Graham’s argument.
D. No. This is close, but the claim is an example intended to disprove a premise of Graham’s argument, not its conclusion. The best life might still be a life that is full of activity; the philosopher just wants to show that Graham’s premise doesn’t actually support his conclusion.
E. No. It is a premise of the philosopher’s argument, not the conclusion.
LSAT PrepTest 52 Section #3 Question #18 Historian: In rebuttal of my claim that West
influenced Stuart, some people point out that
West’s work is mentioned only once in Stuart’s
diaries. But Stuart’s diaries mention several
meetings with West, and Stuart’s close friend,
Abella, studied under West. Furthermore,
Stuart’s work often uses West’s terminology
which, though now commonplace, none of
Stuart’s contemporaries used.
Which one of the following propositions is most
supported by the historian’s statements, if those
statements are true?
(A) Stuart’s discussions with Abella were one of
the means by which West influenced Stuart.
(B) It is more likely that Stuart influenced West
than that West influenced Stuart.
(C) Stuart’s contemporaries were not influenced
by West.
(D) Stuart’s work was not entirely free from West’s
influence
(E) Because of Stuart’s influence on other people,
West’s terminology is now commonplace.
Correct Answer: D
D Principle Match
Find the answer choice supported by the passage.
A. No. The passage does not provide proof whether Stuart had discussions with Abella about West, only that he was friends with Abella, who studied under West.
B. No. The historian is concerned with defending his claim that West influenced Stuart, not the other way around.
C. No. Stuart’s contemporaries didn’t use West’s terminology but there is no proof in the passage that West did or did not otherwise influence them.
D. Yes. Stuart used West’s terminology, which he couldn’t have gotten from his own contemporaries since they did not use the same terminology.
E. No. The passage does not provide any information on why West’s terminology is now commonplace, just that it is.
LSAT PrepTest 52 Section #3 Question #19 One theory to explain the sudden extinction of all
dinosaurs points to “drug overdoses” as the cause.
Angiosperms, a certain class of plants, first appeared
at the time that dinosaurs became extinct. These
plants produce amino-acid-based alkaloids that are
psychoactive agents. Most plant-eating mammals
avoid these potentially lethal poisons because they
taste bitter. Moreover, mammals have livers that help
detoxify such drugs. However, dinosaurs could
neither taste the bitterness nor detoxify the substance
once it was ingested. This theory receives its strongest
support from the fact that it helps explain why so
many dinosaur fossils are found in unusual and
contorted positions.
Which one of the following, if true, would most
undermine the theory presented above?
(A) Many fossils of large mammals are found in
contorted positions.
(B) Angiosperms provide a great deal of nutrition.
(C) Carnivorous dinosaurs mostly ate other,
vegetarian, dinosaurs that fed on
angiosperms.
(D) Some poisonous plants do not produce aminoacid-based alkaloids.
(E) Mammals sometimes die of drug overdoses
from eating angiosperms.
Correct Answer: A
A Weaken
The theory claims that “drug overdoses” were the cause of the sudden extinction of the dinosaurs. This helps explain why so many dinosaur fossils are found in unusual and contorted positions. The evidence is that angiosperms, which contain psychoactive agents, first appeared at the same time that the dinosaurs became extinct. Most plant-eating mammals avoid eating these agents, which are potentially lethal, because they taste bitter. Also, mammals have livers that help detoxify these agents. Dinosaurs couldn’t taste the bitterness, nor could they detoxify the substance. The argument claims that the theory’s strongest support comes from the fact that it helps explain the positions of dinosaur fossils. How does it explain the positions of dinosaur fossils? Might there be other reasons as to why the dinosaur fossils were in these positions?
A. Yes. This widens the gap. If fossils of large mammals are also found in these positions, and mammals were less likely to be poisoned by the psychoactive agents, then a key premise is compromised.
B. No. The argument is about whether dinosaurs were poisoned by angiosperms, not how nutritious angiosperms are.
C. No. This would strengthen the argument. If vegetarian dinosaurs fed on angiosperms and then other dinosaurs ate their angiosperm-polluted bodies, then a lot of dinosaurs would have been in contact with the potentially lethal psychoactive agents in the angiosperms.
D. No. The argument is about whether angiosperms poisoned the dinosaurs, not about other poisonous plants.
E. No. The argument allowed for this possibility. It just implied that it was less likely for them to die from eating angiosperms.
LSAT PrepTest 52 Section #3 Question #20 There are two ways to manage an existing
transportation infrastructure: continuous
maintenance at adequate levels, and periodic radical
reconstruction. Continuous maintenance dispenses
with the need for radical reconstruction, and radical
reconstruction is necessitated by failing to perform
continuous maintenance. Over the long run,
continuous maintenance is far less expensive;
nevertheless, it almost never happens.
Which one of the following, if true, most contributes
to an explanation of why the first alternative
mentioned is almost never adopted?
(A) Since different parts of the transportation
infrastructure are the responsibility of
different levels of government, radical
reconstruction projects are very difficult to
coordinate efficiently.
(B) When funds for transportation infrastructure
maintenance are scarce, they are typically
distributed in proportion to the amount of
traffic that is borne by different elements of
the infrastructure.
(C) If continuous maintenance is performed at
less-than-adequate levels, the need for radical
reconstruction will often arise later than if
maintenance had been restricted to
responding to emergencies.
(D) Radical reconstruction projects are, in general,
too costly to be paid for from current
revenue.
(E) For long periods, the task of regular
maintenance lacks urgency, since the
consequences of neglecting it are very slow to
manifest themselves.
Correct Answer: E
E Resolve/Explain
The discrepancy is that continuous maintenance, which dispenses with the need for radical reconstruction, is far less expensive a way to manage an existing transportation infrastructure in the long run. However, continuous maintenance almost never happens; rather, radical reconstruction, which is necessitated by failing to perform continuous maintenance, is usually the way that an existing transportation infrastructure is managed.
A. No. This would make it more, not less, likely that continuous maintenance would be performed.
B. No. This doesn’t address why continuous maintenance isn’t usually performed, even though it is less expensive in the long run.
C. No. This doesn’t address why continuous adequate maintenance isn’t usually performed.
D. No. This would make it more, not less, likely that continuous maintenance would be performed.
E. Yes. People feel that they can skip maintenance because the problems don’t show up immediately. When they do show up, they are more serious and necessitate radical reconstruction.
LSAT PrepTest 52 Section #3 Question #21 A good way to get over one’s fear of an activity one
finds terrifying is to do it repeatedly. For instance,
over half of people who have parachuted only once
report being extremely frightened by the experience,
while less than 1 percent of those who have
parachuted ten times or more report being
frightened by it.
The reasoning in the argument is most vulnerable to
criticism on the grounds that the argument
(A) takes for granted that the greater the number
of dangerous activities one engages in the less
one is frightened by any one of them
(B) neglects to consider those people who have
parachuted more than once but fewer than
ten times
(C) takes for granted that people do not know how
frightening something is unless they have
tried it
(D) fails to take into account the possibility that
people would be better off if they did not do
things that terrify them
(E) overlooks the possibility that most people who
have parachuted many times did not find it
frightening initially
Correct Answer: E
E Flaw
This argument is designed to solve a problem. The solution proposed for getting over one’s fear of an activity is to do it repeatedly. This is supported by the fact that over 50 percent of the people who have parachuted only once reported being extremely frightened by the experience, while less than 1 percent of people who have parachuted 10 times or more reported being frightened by it. This argument has a sampling problem. Who willingly throws themselves out of an airplane 10 times or more? It could be a higher percentage of people who never found it frightening in the first place.
A. No. The argument addresses overcoming the fear of some particular activity by repeating that same activity, not overcoming the fear of many activities by engaging in lots of frightening activities.
B. No. It’s true that the argument does not address this sample but this is not a flaw of the argument.
C. No. The argument addresses how to get over fears that people already have, no matter how they have acquired this fear.
D. No. What does it mean to be better off? If it means to be less frightened, then the argument does take this into account by saying that, in fact, repeating the activity will make them less frightened of it.
E. Yes. The sample might not be representative because it might include a higher percentage of people who never found it frightening to jump out of a plane in the first place.
LSAT PrepTest 52 Section #3 Question #22 Most economists believe that reducing the price of
any product generally stimulates demand for it.
However, most wine merchants have found that
reducing the price of domestic wines to make them
more competitive with imported wines with which
they were previously comparably priced is frequently
followed by an increase in sales of those imported
wines.
Which one of the following, if true, most helps to
reconcile the belief of most economists with the
consequences observed by most wine merchants?
(A) Economists’ studies of the prices of grocery
items and their rates of sales rarely cover
alcoholic beverages.
(B) Few merchants of any kind have detailed
knowledge of economic theories about the
relationship between item prices and sales
rates.
(C) Consumers are generally willing to forgo
purchasing other items they desire in order to
purchase a superior wine.
(D) Imported wines in all price ranges are
comparable in quality to domestic wines that
cost less.
(E) An increase in the demand for a consumer
product is compatible with an increase in
demand for a competing product.
Correct Answer: E
E Resolve/Explain
The seeming paradox is that although most economists believe that reducing the price of any product generally stimulates demand for it, when most wine merchants reduce the price of domestic wines to make them more competitive with imported wines with which they were previously comparably priced, the sales of the imported wines will increase.
A. No. This still doesn’t explain why, when the general rule is that reducing price stimulates demand, the competing wines sales increased when the prices on the domestic wine were reduced.
B. No. The merchants aren’t the ones making the economic predictions. They are the observers of what actually happened.
C. No. There is no information about which wine is superior. It doesn’t explain why the sales of imported wines increased when domestic wine prices were reduced.
D. No. This does not explain why, if the domestic wines’ prices were reduced, the sales of the imported wines increased.
E. Yes. The argument didn’t say whether the domestic wines’ sales also increased. This allows for the sales of both types of wines to increase, which reconciles the observations with the economists’ beliefs.
LSAT PrepTest 52 Section #3 Question #23 Certain bacteria that produce hydrogen sulfide as a
waste product would die if directly exposed to
oxygen. The hydrogen sulfide reacts with oxygen,
removing it and so preventing it from harming the
bacteria. Furthermore, the hydrogen sulfide tends to
kill other organisms in the area, thereby providing
the bacteria with a source of food. As a result, a dense
colony of these bacteria produces for itself an
environment in which it can continue to thrive
indefinitely.
Which one of the following is most strongly
supported by the information above?
(A) A dense colony of the bacteria can indefinitely
continue to produce enough hydrogen sulfide
to kill other organisms in the area and to
prevent oxygen from harming the bacteria.
(B) The hydrogen sulfide produced by the bacteria
kills other organisms in the area by reacting
with and removing oxygen.
(C) Most organisms, if killed by the hydrogen
sulfide produced by the bacteria, can provide
a source of food for the bacteria.
(D) The bacteria can continue to thrive indefinitely
only in an environment in which the
hydrogen sulfide they produce has removed
all oxygen and killed other organisms in the
area.
(E) If any colony of bacteria produces hydrogen
sulfide as a waste product, it thereby ensures
that it is both provided with a source of food
and protected from harm by oxygen.
Correct Answer: A
A Inference
Find the answer choice supported by the passage.
A. Yes. From the last sentence, a dense colony of these bacteria produces for itself an environment in which it can continue to thrive indefinitely. From the second and third sentence, the hydrogen sulfide produced by these bacteria reacts with oxygen, preventing it from harming the bacteria. It provides the bacteria with a source of food because it tends to kill other organisms in the area.
B. No. The passage states that the hydrogen sulfide reacts with and removes oxygen and that it tends to kill other organisms in the area. There is no proof that these two facts are related.
C. No. There is no proof in the passage that most organisms, if killed, can provide a source of food for the bacteria. All you know is that, with a dense colony, enough will be killed to sustain the colony. They could be light eaters.
D. No. There is no proof that, if they have this environment, the bacteria can thrive indefinitely or that it’s the only way that they can thrive indefinitely.
E. No. There is no information provided about all colonies of bacteria that might produce hydrogen sulfide as a waste product, just about these particular bacteria.
LSAT PrepTest 52 Section #3 Question #24 Books that present a utopian future in which the
inequities and sufferings of the present are replaced
by more harmonious and rational social
arrangements will always find enthusiastic buyers.
Since gloomy books predicting that even more
terrifying times await us are clearly not of this genre,
they are unlikely to be very popular.
The questionable pattern of reasoning in which one
of the following arguments is most similar to that in
the argument above?
(A) Art that portrays people as happy and
contented has a tranquilizing effect on the
viewer, an effect that is appealing to those
who are tense or anxious. Thus, people who
dislike such art are neither tense nor anxious.
(B) People who enjoy participating in activities
such as fishing or hiking may nevertheless
enjoy watching such spectator sports as
boxing or football. Thus, one cannot infer
from someone’s participating in vigorous
contact sports that he or she is not also fond
of less violent forms of recreation.
(C) Action movies that involve complicated and
dangerous special-effects scenes are
enormously expensive to produce. Hence,
since traditional dramatic or comedic films
contain no such scenes, it is probable that
they are relatively inexpensive to produce.
(D) Adults usually feel a pleasant nostalgia when
hearing the music they listened to as
adolescents, but since adolescents often like
music specifically because they think it
annoys their parents, adults rarely appreciate
the music that their children will later listen
to with nostalgia.
(E) All self-employed businesspeople have salaries
that fluctuate with the fortunes of the general
economy, but government bureaucrats are not
self-employed. Therefore, not everyone with
an income that fluctuates with the fortunes of
the general economy is a government
bureaucrat.
Correct Answer: C
C Parallel
The argument concludes that gloomy books are unlikely to be very popular. This is because they are not a genre that presents a utopian future, and books of the utopian future genre will always find enthusiastic buyers. Utopian future → popular; contrapositive: ~popular → ~Utopian future. Conclusion: ~Utopian future → ~(likely) popular. This argument has a necessary/sufficient problem. Being of the utopian future genre is sufficient for being popular but we don’t know that it is necessary. There might well be a group of angst-filled people that like nothing better than to curl up with a gloomy book.
A. No. This argument does not contain the necessary/sufficient switch.
B. No. This argument shifts from people who participate in less violent forms of recreation and enjoy watching more violent sports to people who participate in more violent sports. This is not the same as a necessary/sufficient flaw.
C. Yes. Complicated and dangerous special effects → enormously expensive; ~enormously expensive → ~complicated and dangerous special effects. Conclusion: ~complicated and dangerous special effects → (probably) ~enormously expensive.
D. No. This argument is not flawed.
E. No. This argument is not flawed.
LSAT PrepTest 52 Section #3 Question #25 Some people mistakenly believe that since we do not
have direct access to the distant past we cannot learn
much about it. Contemporary historians and
archaeologists find current geography, geology, and
climate to be rich in clues about a given region’s
distant history. However, the more distant the period
we are studying is, the less useful the study of the
present becomes.
Of the following, which one most closely conforms to
the principle that the passage illustrates?
(A) Astronomers often draw inferences about the
earlier years of our solar system on the basis
of recently collected data. Unfortunately, they
have been able to infer comparatively little
about the origin of our solar system.
(B) Much can be learned about the perpetrator of
a crime by applying scientific methods of
investigation to the crime scene. But the more
the crime scene has been studied the less
likely anything will be learned from further
study.
(C) To understand a literary text one needs to
understand the author’s world view. However,
the farther that world view gets from one’s
own the less one will be able to appreciate the
text.
(D) We often extrapolate from ordinary sensory
experience to things beyond such experience
and form a rash judgment, such as the claim
that the earth is the center of the universe
because it appears that way to us.
(E) One crucial clue to the extent of the ancient
Egyptians’ mathematical knowledge came
from studying the pyramids. The more we
studied such structures, the more impressed
we were by how much the Egyptians knew.
Correct Answer: A
A Parallel
The passage claims that we can learn about the past, even though we do not have direct access to it. We can do this by looking at current geology, geography, etc., to find clues about a region’s distant history. However, the study of the present becomes less useful the more distant the period we are studying is.
A. Yes. The astronomers are able to use present data about the solar system to find out about the earlier years of the solar system. However, because the origin of the solar system is much more distant, the present data is not very useful in learning about this origin.
B. No. The passage tells us that less will be learned from the present the more distant the period is that we are studying. The oft-studied crime scene is not from a much more distant period.
C. No. This doesn’t talk about time relations.
D. No. This doesn’t talk about time relations.
E. No. This doesn’t relate the pyramids to a much more distant time than the ancient Egyptians.
LSAT PrepTest 52 Section #4 Question #1 Many critics agree that the primary characteristic
of Senegalese filmmaker Ousmane Sembène’s work is
its sociopolitical commitment. Sembène was trained
in Moscow in the cinematic methods of socialist
realism, and he asserts that his films are not meant to
entertain his compatriots, but rather to raise their
awareness of the past and present realities of their
society. But his originality as a filmmaker lies most
strikingly in his having successfully adapted film,
originally a Western cultural medium, to the needs,
pace, and structures of West African culture. In
particular, Sembène has found within African oral
culture techniques and strategies that enable him to
express his views and to reach both literate and
nonliterate Senegalese viewers.
A number of Sembène’s characters and motifs can
be traced to those found in traditional West African
storytelling. The tree, for instance, which in countless
West African tales symbolizes knowledge, life, death,
and rebirth, is a salient motif in Emitaï. The trickster,
usually a dishonest individual who personifies
antisocial traits, appears in Borom Sarret, Mandabi,
and Xala as a thief, a corrupted civil servant, and a
member of the elite, respectively. In fact, most of
Sembène’s characters, like those of many oral West
African narratives, are types embodying collective
ideas or attitudes. And in the oral tradition, these
types face archetypal predicaments, as is true, for
example, of the protagonist of Borom Sarret, who has
no name and is recognizable instead by his trade—he
is a street merchant—and by the difficulties he
encounters but is unable to overcome.
Moreover, many of Sembène’s films derive their
structure from West African dilemma tales, the
outcomes of which are debated and decided by their
audiences. The open-endedness of most of his plots
reveals that Sembène similarly leaves it to his
viewers to complete his narratives: in such films as
Borom Sarret, Mandabi, and Ceddo, for example, he
provides his spectators with several alternatives as the
films end. The openness of his narratives is also
evidenced by his frequent use of freeze-frames, which
carry the suggestion of continued action.
Finally, like many West African oral tales,
Sembène’s narratives take the form of initiatory
journeys that bring about a basic change in the
worldview of the protagonist and ultimately, Sembène
hopes, in that of the viewer. His films denounce
social and political injustice. and his protagonists’
social consciousness emerges from an acute selfconsciousness brought about by the juxtaposition of
opposites within the films’ social context: good versus
evil, powerlessness versus power, or poverty versus
wealth. Such binary oppositions are used analogously
in West African tales, and it seems likely that these
dialectical elements are related to African oral
storytelling more than, as many critics have supposed,
to the Marxist components of his ideology.
- Which one of the following most accurately states the
main point of the passage?
(A) Sembène’s originality as a filmmaker lies in his
adaptation of traditional archetypal
predicaments and open-ended plots, both of
which are derived from West African oral
tales.
(B) Many of the characters in Sembène’s films are
variations on character types common to
traditional West African storytelling.
(C) Sembène’s films derive their distinctive
characteristics from oral narrative traditions
that had not previously been considered
suitable subject matter for films.
(D) Sembène’s films give vivid expression to the
social and political beliefs held by most of the
Senegalese people.

elements derived from traditional West
African storytelling to comment critically on
contemporary social and political issues.

Which one of the following would, if true, most
strengthen the claim made by the author in the last

(A) Several African novelists who draw upon the
oral traditions of West Africa use binary
oppositions as fundamental structures in
their narratives, even though they have not
read Marxist theory.
(B) Folklorists who have analyzed oral storytelling
traditions from across the world have found
that the use of binary oppositions to
structure narratives is common to many of
these traditions.
(C) When he trained in Moscow, Sembène read
extensively in Marxist political theory and
worked to devise ways of synthesizing
Marxist theory and the collective ideas
expressed in West African storytelling.
(D) Very few filmmakers in Europe or North
America make use of binary oppositions to

Correct Answer: A
Passage Analysis
A RC Reasoning
The answer choice should support the author’s reading of the dialectical elements as being related to African oral storytelling rather than to the Marxist components of Sembène’s ideology.
A. Yes. This choice demonstrates that other people who draw upon the oral traditions of West Africa do use these dialectical elements, and these people haven’t read Marxist theory. It lends credence to the author’s claim.
B. No. This is too general. The author claims that the binary oppositions are more likely to have come from African oral storytelling, not just some tradition from around the world.
C. No. This weakens the argument. If this were true, then the binary elements would be likely to come equally from his Marxist ideology.
D. No. This is not strong enough. There are other continents besides Europe, North America, and Africa. Also, he still could have gotten the binary oppositions from his Marxist ideology, even if few North American and European filmmakers use binary opposition.
E. No. This is not strong enough. It just says that some films produced by Marxist-principled filmmakers don’t essentially use binary opposition. They could still produce a lot of films that do.

and Xala as a thief, a corrupted civil servant, and a
member of the elite, respectively. In fact, most of
Sembène’s characters, like those of many oral West
African narratives, are types embodying collective
ideas or attitudes. And in the oral tradition, these
types face archetypal predicaments, as is true, for
example, of the protagonist of Borom Sarret, who has
no name and is recognizable instead by his trade—he
is a street merchant—and by the difficulties he
encounters but is unable to overcome.
Moreover, many of Sembène’s films derive their
structure from West African dilemma tales, the
outcomes of which are debated and decided by their
audiences. The open-endedness of most of his plots
reveals that Sembène similarly leaves it to his
viewers to complete his narratives: in such films as
Borom Sarret, Mandabi, and Ceddo, for example, he
provides his spectators with several alternatives as the
films end. The openness of his narratives is also
evidenced by his frequent use of freeze-frames, which
carry the suggestion of continued action.
Finally, like many West African oral tales,
Sembène’s narratives take the form of initiatory
journeys that bring about a basic change in the
worldview of the protagonist and ultimately, Sembène
hopes, in that of the viewer. His films denounce
social and political injustice. and his protagonists’
social consciousness emerges from an acute selfconsciousness brought about by the juxtaposition of
opposites within the films’ social context: good versus
evil, powerlessness versus power, or poverty versus
wealth. Such binary oppositions are used analogously
in West African tales, and it seems likely that these
dialectical elements are related to African oral
storytelling more than, as many critics have supposed,
to the Marxist components of his ideology.
The passage does NOT provide evidence that
Sembène exhibits which one of the following
attitudes in one or more of his films?
(A) disenchantment with attempts to reform
Senegalese government
(B) confidence in the aptness of using traditional
motifs to comment on contemporary issues
(C) concern with social justice
(D) interest in the vicissitudes of ordinary people’s
lives
(E) desire to educate his audience
Correct Answer: A
Passage Analysis
A Extract Fact
A. Yes. The passage never says that one of his films exhibits disenchantment with attempts to reform Senegalese government.
B. No. Paragraph two says that he does this a lot, which provides evidence that Sembène exhibits confidence in the aptness of it.
C. No. Paragraph four discusses this.
D. No. The example of the street merchant in the second paragraph shows this.
E. No. The first paragraph talks about his desire to raise awareness.

Passage B
Writing is at the heart of the lawyer’s craft, and so,
like it or not, we who teach the law inevitably teach
aspiring lawyers how lawyers write. We do this in a few
stand-alone courses and, to a greater extent, through the
constraints that we impose on their writing throughout
the curriculum. Legal writing, because of the purposes
it serves, is necessarily ruled by linear logic, creating a
path without diversions, surprises, or reversals.
Conformity is a virtue, creativity suspect, humor
forbidden, and voice mute.
Lawyers write as they see other lawyers write, and,
influenced by education, profession, economic
constraints, and perceived self-interest, they too often
write badly. Perhaps the currently fashionable call for
attention to narrative in legal education could have an
effect on this. It is not yet exactly clear what role
narrative should play in the law, but it is nonetheless
true that every case has at its heart a story—of real
events and people, of concerns, misfortunes, conflicts,
feelings. But because legal analysis strips the human
narrative content from the abstract, canonical legal
form of the case, law students learn to act as if there is
no such story.
It may well turn out that some of the terminology
and public rhetoric of this potentially subversive
movement toward attention to narrative will find its
way into the law curriculum, but without producing
corresponding changes in how legal writing is actually
taught or in how our future colleagues will write. Still,
even mere awareness of the value of narrative could
perhaps serve as an important corrective.

LSAT PrepTest 52 Section #4 Question #13 Traditional theories of animal behavior assert that
animal conflict within a species is highly ritualized
and does not vary from contest to contest. This
species-specific model assumes that repetitive use of
the same visual and vocal displays and an absence of
escalated fighting evolved to prevent injury. The
contestant that exhibits the “best” display wins the
contested resource. Galápagos tortoises, for instance,
settle contests on the basis of height: the ritualized
display consists of two tortoises facing one another
and stretching their necks skyward; the tortoise
perceived as being “taller” wins.
In populations of the spider Agelenopsis aperta,
however, fighting behavior varies greatly from contest
to contest. In addition, fighting is not limited to
displays: biting and shoving are common. Susan
Riechert argues that a recently developed model,
evolutionary game theory, provides a closer fit to
A. aperta territorial disputes than does the speciesspecific model, because it explains variations in
conflict behavior that may result from varying
conditions, such as differences in size, age, and
experience of combatants. Evolutionary game theory
was adapted from the classical game theory that was
developed by von Neumann and Morganstern to
explain human behavior in conflict situations. In both
classical and evolutionary game theory, strategies are
weighed in terms of maximizing the average payoff
against contestants employing both the same and
different strategies. For example, a spider may engage
in escalated fighting during a dispute only if the
disputed resource is valuable enough to warrant the
risk of physical injury. There are, however, two major
differences between the classical and evolutionary
theories. First, whereas in classical game theory it is
assumed that rational thought is used to determine
which action to take, evolutionary game theory
assumes that instinct and long-term species advantage
ultimately determine the strategies that are exhibited.
The other difference is in the payoffs: in classical
game theory, the payoffs are determined by an
individual’s personal judgment of what constitutes
winning; in evolutionary game theory, the payoffs are
defined in terms of reproductive success.
In studying populations of A. aperta in a
grassland habitat and a riparian habitat, Riechert
predicts that such factors as the size of the opponents,
the potential rate of predation in a habitat, and the
probability of winning a subsequent site if the dispute
is lost will all affect the behavior of spiders in
territorial disputes. In addition, she predicts that the
markedly different levels of competition for web sites
in the two habitats will affect the spiders’ willingness
to engage in escalated fighting. In the grassland,
where 12 percent of the habitat is available for
occupation by A. aperta, Riechert predicts that
spiders will be more willing to engage in escalated
fighting than in the riparian habitat, where 90 percent
of the habitat is suitable for occupation.
Which one of the following best states the main idea
of the passage?
(A) Evolutionary game theory and classical game
theory can be used to analyze the process of
decision-making used by humans and
animals in settling disputes.
(B) A. aperta in grassland habitats and riparian
habitats exhibit an unusually wide variety of
fighting behaviors in territorial disputes.
(C) Evolutionary game theory may be useful in
explaining the behavior of certain spiders
during territorial disputes.
(D) The traditional theory of animal behavior in
conflict situations cannot be used to explain
the fighting behavior of most species.
(E) Evolutionary game theory, adapted from
classical game theory, is currently used by
scientists to predict the behavior of spiders in
site selection.
Correct Answer: C
Passage Analysis
C Big Picture
A. No. This is too general. The passage discusses only evolutionary game theory in terms of its success in analyzing the process of decision making, and only in regards to Agelenopsis apertas.
B. No. This was discussed only in the third paragraph. Also, we don’t know that they exhibit an unusually wide variety of behaviors.
C. Yes. This mentions evolutionary game theory and how it might be used to explain the behavior of Agelenopsis apertas in intra-species disputes.
D. No. This is too strong. The author suggests that the traditional theory might not be as good as evolutionary game theory to explain the fighting behavior of Agelenopsis apertas, but doesn’t address most species.
E. No. This is too general. We don’t know that scientists in general use evolutionary game theory to predict the behavior of spiders in site selection.

disputed resource is valuable enough to warrant the
risk of physical injury. There are, however, two major
differences between the classical and evolutionary
theories. First, whereas in classical game theory it is
assumed that rational thought is used to determine
which action to take, evolutionary game theory
assumes that instinct and long-term species advantage
ultimately determine the strategies that are exhibited.
The other difference is in the payoffs: in classical
game theory, the payoffs are determined by an
individual’s personal judgment of what constitutes
winning; in evolutionary game theory, the payoffs are
defined in terms of reproductive success.
In studying populations of A. aperta in a
grassland habitat and a riparian habitat, Riechert
predicts that such factors as the size of the opponents,
the potential rate of predation in a habitat, and the
probability of winning a subsequent site if the dispute
is lost will all affect the behavior of spiders in
territorial disputes. In addition, she predicts that the
markedly different levels of competition for web sites
in the two habitats will affect the spiders’ willingness
to engage in escalated fighting. In the grassland,
where 12 percent of the habitat is available for
occupation by A. aperta, Riechert predicts that
spiders will be more willing to engage in escalated
fighting than in the riparian habitat, where 90 percent
of the habitat is suitable for occupation.

The author mentions Galapagos tortoises as an example of the traditional theory, which claims that intra-species conflict is highly ritualized. This supports (E).
LSAT PrepTest 52 Section #4 Question #15 Traditional theories of animal behavior assert that
animal conflict within a species is highly ritualized
and does not vary from contest to contest. This
species-specific model assumes that repetitive use of
the same visual and vocal displays and an absence of
escalated fighting evolved to prevent injury. The
contestant that exhibits the “best” display wins the
contested resource. Galápagos tortoises, for instance,
settle contests on the basis of height: the ritualized
display consists of two tortoises facing one another
and stretching their necks skyward; the tortoise
perceived as being “taller” wins.
In populations of the spider Agelenopsis aperta,
however, fighting behavior varies greatly from contest
to contest. In addition, fighting is not limited to
displays: biting and shoving are common. Susan
Riechert argues that a recently developed model,
evolutionary game theory, provides a closer fit to
A. aperta territorial disputes than does the speciesspecific model, because it explains variations in
conflict behavior that may result from varying
conditions, such as differences in size, age, and
experience of combatants. Evolutionary game theory
was adapted from the classical game theory that was
developed by von Neumann and Morganstern to
explain human behavior in conflict situations. In both
classical and evolutionary game theory, strategies are
weighed in terms of maximizing the average payoff
against contestants employing both the same and
different strategies. For example, a spider may engage
in escalated fighting during a dispute only if the
disputed resource is valuable enough to warrant the

LSAT PrepTest 52 Section #4 Question #20 Most people acknowledge that not all
governments have a moral right to govern and that
there are sometimes morally legitimate reasons for
disobeying the law, as when a particular law
prescribes behavior that is clearly immoral. It is also
commonly supposed that such cases are special
exceptions and that, in general, the fact that
something is against the law counts as a moral, as
well as legal, ground for not doing it; i.e., we
generally have a moral duty to obey a law simply
because it is the law. But the theory known as
philosophical anarchism denies this view, arguing
instead that people who live under the jurisdiction of
governments have no moral duty to those
governments to obey their laws. Some commentators
have rejected this position because of what they take
to be its highly counterintuitive implications: (1) that
no existing government is morally better than any
other (since all are, in a sense, equally illegitimate),
and (2) that, lacking any moral obligation to obey any
laws, people may do as they please without scruple.
In fact, however, philosophical anarchism does not
entail these claims.
First, the conclusion that no government is
morally better than any other does not follow from
the claim that nobody owes moral obedience to any
government. Even if one denies that there is a moral
obligation to follow the laws of any government, one
can still evaluate the morality of the policies and
actions of various governments. Some governments
do more good than harm, and others more harm than
good, to their subjects. Some violate the moral rights
of individuals more regularly, systematically, and
seriously than others. In short, it is perfectly
consistent with philosophical anarchism to hold that
governments vary widely in their moral stature.
Second, philosophical anarchists maintain that all
individuals have basic, nonlegal moral duties to one
another—duties not to harm others in their lives,
liberty, health, or goods. Even if governmental laws
have no moral force, individuals still have duties to
refrain from those actions that constitute crimes in the
majority of legal systems (such as murder, assault,
theft, and fraud). Moreover, philosophical anarchists
hold that people have a positive moral obligation to
care for one another, a moral obligation that they
might even choose to discharge by supporting
cooperative efforts by governments to help those in
need. And where others are abiding by established
laws, even those laws derived from mere conventions,
individuals are morally bound not to violate those
laws when doing so would endanger others. Thus, if
others obey the law and drive their vehicles on the
right, one must not endanger them by driving on the
left, for, even though driving on the left is not
inherently immoral, it is morally wrong to deliberately
harm the innocent.
Which one of the following most accurately expresses
the main point of the passage?
(A) Some views that certain commentators
consider to be implications of philosophical
anarchism are highly counterintuitive.
(B) Contrary to what philosophical anarchists
claim, some governments are morally
superior to others, and citizens under
legitimate governments have moral
obligations to one another.
(C) It does not follow logically from philosophical
anarchism that no government is morally
better than any other or that people have no
moral duties toward one another.
(D) Even if, as certain philosophical anarchists
claim, governmental laws lack moral force,
people still have a moral obligation to refrain
from harming one another.
(E) Contrary to what some of its opponents have
claimed, philosophical anarchism does not
conflict with the ordinary view that one
should obey the law because it is the law.

to be its highly counterintuitive implications: (1) that
no existing government is morally better than any
other (since all are, in a sense, equally illegitimate),
and (2) that, lacking any moral obligation to obey any
laws, people may do as they please without scruple.
In fact, however, philosophical anarchism does not
entail these claims.
First, the conclusion that no government is
morally better than any other does not follow from
the claim that nobody owes moral obedience to any
government. Even if one denies that there is a moral
obligation to follow the laws of any government, one
can still evaluate the morality of the policies and
actions of various governments. Some governments
do more good than harm, and others more harm than
good, to their subjects. Some violate the moral rights
of individuals more regularly, systematically, and
seriously than others. In short, it is perfectly
consistent with philosophical anarchism to hold that
governments vary widely in their moral stature.
Second, philosophical anarchists maintain that all
individuals have basic, nonlegal moral duties to one
another—duties not to harm others in their lives,
liberty, health, or goods. Even if governmental laws
have no moral force, individuals still have duties to
refrain from those actions that constitute crimes in the
majority of legal systems (such as murder, assault,
theft, and fraud). Moreover, philosophical anarchists
hold that people have a positive moral obligation to
care for one another, a moral obligation that they
might even choose to discharge by supporting
cooperative efforts by governments to help those in
need. And where others are abiding by established
laws, even those laws derived from mere conventions,
individuals are morally bound not to violate those
laws when doing so would endanger others. Thus, if
others obey the law and drive their vehicles on the
right, one must not endanger them by driving on the
left, for, even though driving on the left is not
inherently immoral, it is morally wrong to deliberately
harm the innocent.
- Which one of the following scenarios most
completely conforms to the views attributed to
philosophical anarchists in lines 37–44?
(A) A member of a political party that is illegal in
a particular country divulges the names of
other members because he fears legal
penalties.
(B) A corporate executive chooses to discontinue
her company’s practice of dumping chemicals
illegally when she learns that the chemicals
are contaminating the water supply.
(C) A person who knows that a coworker has
stolen funds from their employer decides to
do nothing because the coworker is widely
admired.
(D) A person neglects to pay her taxes, even
though it is likely that she will suffer severe
legal penalties as a consequence, because she
wants to use the money to finance a new
business.
(E) A driver determines that it is safe to exceed the
posted speed limit, in spite of poor visibility,
because there are apparently no other vehicles
on the road
Correct Answer: B
Passage Analysis
B Extract Infer
A. No. The last part of the analogy discusses legal penalties, which the anarchists don’t recognize as being pertinent to morality.
B. Yes. The corporate executive refrains from a practice because she finds out it might be hurting others.
C. No. The coworker has hurt someone else but the person does nothing.
D. No. This doesn’t discuss the possibility of hurting others.
E. No. This action does not discuss the reasons for refraining from an action.
LSAT PrepTest 52 Section #4 Question #23 Most people acknowledge that not all

something is against the law counts as a moral, as

- By attributing to commentators the view that
philosophical anarchism has implications that are
“counterintuitive” (line 17), the author most likely
means that the commentators believe that
(A) the implications conflict with some commonly
held beliefs
(B) there is little empirical evidence that the
implications are actually true
(C) common sense indicates that philosophical
anarchism does not have such implications
(D) the implications appear to be incompatible
with each other
(E) each of the implications contains an internal
logical inconsistency

D. Yes. The author tries to show that the critics are wrong in thinking that philosophical anarchism has, as its implications, two counterintuitive claims.
E. No. The author argues that the supposedly counterintuitive implications are not actual implications of philosophical anarchism and, therefore, are not defects of philosophical anarchism.
- Consumer advocate: Businesses are typically
motivated primarily by the desire to make as
great a profit as possible, and advertising helps
businesses to achieve this goal. But it is clear
that the motive of maximizing profits does not
impel businesses to present accurate
information in their advertisements. It follows
that consumers should be skeptical of the
claims made in advertisements.
Each of the following, if true, would strengthen the
consumer advocate’s argument EXCEPT:
(A) Businesses know that they can usually
maximize their profits by using inaccurate
information in their advertisements.
(B) Businesses have often included inaccurate
information in their advertisements.
(C) Many consumers have a cynical attitude
toward advertising.
(D) Those who create advertisements are less
concerned with the accuracy than with the
creativity of advertisements.
(E) The laws regulating truth in advertising are
not applicable to many of the most common
forms of inaccurate advertising
Correct Answer: C
C Strengthen
The consumer advocate concludes that consumers ought to be skeptical of the claims made in advertisements. The evidence is that, typically, businesses are chiefly motivated by profits, and this motive does not make businesses think that they should present accurate information in their advertisements. The consumer advocate is neglecting to consider other reasons that businesses might not make misleading claims in advertisements, despite their interests in making a profit.
A. No. This strengthens the connection between maximizing profits and using inaccurate information.
B. No. This indicates a past history of businesses making inaccurate statements, thus strengthening the conclusion.
C. Yes. The conclusion claims that consumers OUGHT to be skeptical. It doesn’t address whether they actually ARE skeptical or not.
D. No. This strengthens the claim that advertisements are likely to contain inaccurate information.
E. No. This eliminates another reason as to why businesses might give accurate information, even though they want to increase profits.
Elaine: The purpose of art museums is to preserve
artworks and make them available to the
public. Museums, therefore, should seek to
acquire and display the best examples of
artworks from each artistic period and genre,
even if some of these works are not recognized
by experts as masterpieces.
Frederick: Art museums ought to devote their limited
resources to acquiring the works of recognized
masters in order to ensure the preservation of
the greatest artworks.
Elaine’s and Frederick’s statements provide the most
support for the claim that they would disagree about
whether
(A) many artistic masterpieces are not recognized
as such by art experts
(B) museums should seek to represent all genres of
art in their collections
(C) art museums should seek to preserve works of art
(D) an art museum ought to acquire an unusual
example of a period or genre if more
characteristic examples are prohibitively
expensive
(E) all of the artworks that experts identify as
masterpieces are actually masterpieces
Correct Answer: B
B Point at Issue
Elaine concludes that museums ought to seek to acquire the best examples of artworks from each period and genre, even if some of the works are not recognized as masterpieces. Her premise is that the purpose of museums is to preserve artworks and make them available to all. Frederick disagrees, claiming that art museums ought to acquire the works of recognized masters, as museums have limited resources and a museum’s purpose is to ensure the preservation of the greatest artworks.
A. No. Frederick does not make any connection between greatest artworks and who deems them as such.
B. Yes. Elaine claims that they should, while Frederick thinks that museums have a different purpose.
C. No. Both Elaine and Frederick agree on this.
D. No. Neither is concerned with the expense of a single piece of art.
E. No. Neither questions the status of artwork identified as masterpieces.
- Science columnist: It is clear why humans have so
many diseases in common with cats. Many
human diseases are genetically based, and cats
are genetically closer to humans than are any
other mammals except nonhuman primates.
Each of the genes identified so far in cats has
an exact counterpart in humans.
Which one of the following, if true, most weakens the
science columnist’s explanation for the claim that
humans have so many diseases in common with cats?
(A) Cats have built up resistance to many of the
diseases they have in common with humans.
(B) Most diseases that humans have in common
with cats have no genetic basis.
(C) Cats have more diseases in common with
nonhuman primates than with humans.
(D) Many of the diseases humans have in common
with cats are mild and are rarely diagnosed.
(E) Humans have more genes in common with
nonhuman primates than with cats.
Correct Answer: B
B Weaken
The science columnist presents the following evidence: Many human diseases are genetically based, and cats are genetically closer to humans than are any other mammals save nonhuman primates. The columnist claims that this evidence makes is clear why humans and cats have so many diseases in common.
A. No. The argument doesn’t make claims about how many cats (as opposed to humans) actually get the diseases.
B. Yes. The argument claims only that many human diseases are genetically based, not all. And it doesn’t tell us whether the diseases we share with cats are among those. If they are not, the fact that cats are genetically close to humans still doesn’t explain why cats and humans share a lot of diseases.
C. No. The argument doesn’t address the diseases cats and nonhuman primates have in common.
D. No. The argument doesn’t address the severity of the diseases shared by humans and cats.
E. No. The argument already states this.
This region must find new ways to help business
grow. After all, shoe manufacturing used to be a
major local industry, but recently has experienced
severe setbacks due to overseas competition, so there
is a need for expansion into new manufacturing
areas. Moreover, our outdated public policy generally
inhibits business growth.
Which one of the following most accurately expresses
the main conclusion drawn in the argument?
(A) The region needs to find new ways to enhance
business growth.
(B) Shoe manufacturing is no longer a major
source of income in the region.
(C) Shoe manufacturing in the region has
dramatically declined due to overseas
competition.
(D) Business in the region must expand into new
areas of manufacturing.
(E) Outdated public policy inhibits business
growth in the region.
Correct Answer: A
A Main Point
Because shoe manufacturing, which used to be a major local industry, has experienced severe setbacks and because outdated public policy generally prevents business growth, the argument concludes that this region must find new ways to help business grow.
A. Yes. This is a restatement of the conclusion.
B. No. We don’t know whether it is still a major source of income or not.
C. No. This is a premise.
D. No. This is a premise.
E. No. This is a premise.
As a result of modern medicine, more people have
been able to enjoy long and pain-free lives. But the
resulting increase in life expectancy has contributed
to a steady increase in the proportion of the
population that is of advanced age. This population
shift is creating potentially devastating financial
problems for some social welfare programs.
Which one of the following propositions is most
precisely exemplified by the situation presented above?
(A) Technical or scientific innovation cannot be
the solution to all problems.
(B) Implementing technological innovations
should be delayed until the resulting social
changes can be managed.
(C) Every enhancement of the quality of life has
unavoidable negative consequences.
(D) All social institutions are affected by a
preoccupation with prolonging life.
(E) Solving one set of problems can create a
different set of problems.
Correct Answer: E
E Principle Match
Modern medicine has enabled more people to live longer and pain-free lives. However, the benefits created by modern medicine have resulted in more and more of the population being older, which gives rise to financial problems for some social welfare programs.
A. No. This is too strong. The passage doesn’t discuss all problems.
B. No. The passage does not make a recommendation as to what should be done. It describes a situation.
C. No. This is too strong. The passage doesn’t discuss every enhancement of the quality of life.
D. No. This is too strong. The passage doesn’t discuss all social institutions, just some.
E. Yes. Modern medicine solved the short and painful life-span problem, but in the process it created a financial problem.
Since Jackie is such a big fan of Moral Vacuum’s
music, she will probably like The Cruel Herd’s new
album. Like Moral Vacuum, The Cruel Herd on this
album plays complex rock music that employs the
acoustic instrumentation and harmonic
sophistication of early sixties jazz. The Cruel Herd
also has very witty lyrics, full of puns and sardonic
humor, like some of Moral Vacuum’s best lyrics.
Which one of the following, if true, most strengthens
the argument?
(A) Jackie has not previously cared for The Cruel
Herd, but on the new album The Cruel Herd’s
previous musical arranger has been replaced
by Moral Vacuum’s musical arranger.
(B) Though The Cruel Herd’s previous albums’
production quality was not great, the new
album is produced by one of the most widely
employed producers in the music industry.
(C) Like Moral Vacuum, The Cruel Herd regularly
performs in clubs popular with many
students at the university that Jackie attends.
(D) All of the music that Jackie prefers to listen to
on a regular basis is rock music.
(E) Jackie’s favorite Moral Vacuum songs have
lyrics that are somber and marked by a strong
political awareness.
Correct Answer: A
A Strengthen
The argument concludes that Jackie will probably like The Cruel Herd’s new album. Jackie is a fan of Moral Vacuum’s music and, on this album, The Cruel Herd plays a type of music similar to Moral Vacuum’s. Also, the witty lyrics are similar to those of some of Moral Vacuum’s best. This is an analogy and the answer choice should make the two bands’ music even more similar.
A. Yes. If The Cruel Herd’s new musical arranger is Moral Vacuum’s musical arranger, the two bands’ music should be even more similar.
B. No. This doesn’t make The Cruel Herd sound more like Moral Vacuum.
C. No. This is too general. We don’t know that these clubs are popular with Jackie.
D. No. This doesn’t make The Cruel Herd sound more like Moral Vacuum.
E. No. This weakens the argument. If Jackie likes the somber and political Moral Vacuum lyrics, then she might not like the witty lyrics of The Cruel Herd
Doctor: In three separate studies, researchers
compared children who had slept with nightlights in their rooms as infants to children who
had not. In the first study, the children who
had slept with night-lights proved more likely
to be nearsighted, but the later studies found
no correlation between night-lights and
nearsightedness. However, the children in the
first study were younger than those in the later
studies. This suggests that if night-lights cause
nearsightedness, the effect disappears with age.
Which one of the following, if true, would most
weaken the doctor’s argument?
(A) A fourth study comparing infants who were
currently sleeping with night-lights to infants
who were not did not find any correlation
between night-lights and nearsightedness.
(B) On average, young children who are already
very nearsighted are no more likely to sleep
with night-lights than young children who are
not already nearsighted.
(C) In a study involving children who had not
slept with night-lights as infants but had slept
with night-lights when they were older, most
of the children studied were not nearsighted.
(D) The two studies in which no correlation was
found did not examine enough children to
provide significant support for any
conclusion regarding a causal relationship
between night-lights and nearsightedness.
(E) In a fourth study involving 100 children who
were older than those in any of the first three
studies, several of the children who had slept
with night-lights as infants were nearsighted.
Correct Answer: D
D Weaken
The doctor concludes that the evidence suggests that, if it’s true that night-lights cause nearsightedness, the effect disappears with age. He cites as evidence the results of three separate studies concerning children who had or had not slept with night-lights as infants. The first study involved children who were younger than those in the other studies, and it was only in the first study that a correlation between sleeping with a night-light and nearsightedness was observed. The doctor’s language is very tentative, even in his conclusion, so the weakness of the argument must lie in the studies themselves.
A. No. The doctor doesn’t claim that sleeping with a night-light definitely causes nearsightedness.
B. No. The doctor doesn’t claim that sleeping with a night-light definitely causes nearsightedness, so this is irrelevant.
C. No. The evidence and conclusion concern the possible correlation between infants sleeping with night-lights and nearsightedness, not older children.
D. Yes. This answer choice attacks the studies themselves. If the sample size is not large enough, the studies can’t give enough support to the doctor’s claim that, if there is a causal relationship, the effect disappears with time.
E. No. There needs to be more than a few children who are still nearsighted to show anything definitively. These few might be nearsighted for other reasons.
- Superconductors are substances that conduct electricity
without resistance at low temperatures.Their use,
however,will never be economically feasible, unless there
is a substance that superconducts at a temperature above
minus 148 degrees Celsius.If there is such a substance,
that substance must be an alloy of niobium and
germanium. Unfortunately,such alloys superconduct at
temperatures no higher than minus 160 degrees Celsius.
If the statements above are true, which one of the
following must also be true?
(A) The use of superconductors will never be
economically feasible.
(B) If the alloys of niobium and germanium do
not superconduct at temperatures above

other substances that will do so.
(C) The use of superconductors could be

that superconducts at temperatures below
minus 148 degrees Celsius.
(D) Alloys of niobium and germanium do not
superconduct at temperatures below minus

(E) No use of alloys of niobium and germanium
will ever be economically feasible.
Correct Answer: A
A Inference
Connect the facts. Economically feasible → superconducts above –148°C; ~superconduct above –148°C → ~economically feasible. Superconducts above –148°C → alloy of niobium and germanium; ~ alloy of niobium and germanium → ~superconduct above –148°C. Alloys of niobium and germanium superconduct at –160°C or lower. Therefore, ~superconduct above –148°C → ~economically feasible.
A. Yes. Given the information above, this must be true.
B. No. According to the passage, if anything will superconduct above –148°C, it would have to be an alloy of niobium and germanium.
C. No. We know that, if they are going to be economically feasible at all, they must superconduct above –148°C.
D. No. We don’t know this.
E. No. This is too strong. Their use might be economically feasible in other areas besides superconducting.
Public health experts have waged a long-standing
educational campaign to get people to eat more
vegetables, which are known to help prevent cancer.
Unfortunately, the campaign has had little impact on
people’s diets. The reason is probably that many
people simply dislike the taste of most vegetables.
Thus, the campaign would probably be more
effective if it included information on ways to make
vegetables more appetizing.
Which one of the following, if true, most strengthens
the argument?
(A) The campaign to get people to eat more
vegetables has had little impact on the diets of
most people who love the taste of vegetables.
(B) Some ways of making vegetables more
appetizing diminish vegetables’ ability to help
prevent cancer.
(C) People who find a few vegetables appetizing
typically do not eat substantially more
vegetables than do people who dislike the
taste of most vegetables.
(D) People who dislike the taste of most vegetables
would eat many more vegetables if they knew
how to make them more appetizing.
(E) The only way to make the campaign to get
people to eat more vegetables more effective
would be to ensure that anyone who at
present dislikes the taste of certain vegetables
learns to find those vegetables appetizing
Correct Answer: D
D Strengthen
There has been a long-standing campaign to get people to eat more vegetables. However, this campaign has had little impact on what people eat. The offered solution to make the campaign more effective is to include information on ways to make vegetables more appetizing, as the argument claims that the probable reason for the campaign’s ineffectiveness is that many people dislike the taste of most vegetables. The answer will strengthen the connection between the campaign’s ineffectiveness and people’s dislike of most vegetables as they now prepare them.
A. No. This weakens the argument. If it doesn’t make people who love vegetables eat more of them, then giving people information about how to make veggies tastier won’t make people eat more of them.
B. No. This weakens the argument. The campaign urges people to eat more vegetables in order to help prevent cancer. If eating the vegetables once they have been made more appetizing is less likely to prevent cancer, then the campaign will fail in its ultimate goal.
C. No. This weakens the argument.
D. Yes. If knowing how to make the vegetables more appetizing will cause people to eat more vegetables, then the campaign would likely be more effective if it gave out that information.
E. No. The campaign wants people to eat vegetables in general, not specific kinds of vegetables. If the people who disliked broccoli started to eat more Brussels sprouts and green beans, the campaign would still be more effective than it is now, even if these people never learned to like broccoli.
. Global surveys estimate the earth’s population of
nesting female leatherback turtles has fallen by more
than two-thirds in the past 15 years. Any species
whose population declines by more than two-thirds
in 15 years is in grave danger of extinction, so the
leatherback turtle is clearly in danger of extinction.
Which one of the following is an assumption that the
argument requires?
(A) The decline in the population of nesting
female leatherback turtles is proportional to
the decline in the leatherback turtle
population as a whole.
(B) If the global population of leatherback turtles
falls by more than two-thirds over the next 15
years, the species will eventually become
extinct.
(C) The global population of leatherback turtles
consists in roughly equal numbers of females
and males.
(D) Very few leatherback turtles exist in captivity.
(E) The only way to ensure the continued survival
of leatherback turtles in the wild is to breed
them in captivity
Correct Answer: A
A Necessary Assumption
The argument concludes that the leatherback turtle is in danger of extinction, based on evidence about nesting female leatherback turtles. This population of turtles has fallen by more than two-thirds in the past 15 years. Any species whose population declines by that amount in that amount of time is in grave danger of extinction. There needs to be a connection between the statistics for nesting female leatherback turtles and the leatherback turtle population as a whole.
A. Yes. This connects the decline of nesting female leatherback turtles to a similar decline in the leatherback turtle population as a whole.
B. No. This is too strong. The argument never claims that the turtles will actually become extinct.
C. No. This is too general. The argument needs a connection between the numbers of nesting female leatherbacks and the leatherback population as a whole. This compares the numbers of females in general with the number of males.
D. No. The argument doesn’t address turtles in captivity.
E. No. The argument doesn’t attempt to solve the problem; it just points out the problem.
Pure science—research with no immediate
commercial or technological application—is a public
good. Such research requires a great amount of
financial support and does not yield profits in the
short term. Since private corporations will not
undertake to support activities that do not yield
short-term profits, a society that wants to reap the
benefits of pure science ought to use public funds to
support such research.
The claim about private corporations serves which
one of the following functions in the argument?
(A) It expresses the conclusion of the argument.
(B) It explains what is meant by the expression
“pure research” in the context of the
argument.
(C) It distracts attention from the point at issue by
introducing a different but related goal.
(D) It supports the conclusion by ruling out an
alternative way of achieving the benefits
mentioned.
(E) It illustrates a case where unfortunate
consequences result from a failure to accept
the recommendation offered.
Correct Answer: D
D Reasoning
The argument concludes that a society that wants to reap the benefits of pure science ought to use public funds to support such research. The argument defines pure science as research with no immediate commercial or technological application and claims that it is a public good. Because of its nature, pure science needs a lot of monetary support and doesn’t make profits in the short term. The argument then eliminates another possible funding avenue for pure science by claiming that private corporations will not fund activities that do not yield short-term profits.
A. No. The claim about private corporations is not the conclusion.
B. No. The claim about private corporations does not help define “pure research.”
C. No. The claim about private corporations does not address a different goal.
D. Yes. This claim eliminates another possible funding source for pure science, which benefits the public.
E. No. This claim is not an example, so it doesn’t illustrate a case.
- Some doctors believe that a certain drug reduces the
duration of episodes of vertigo, claiming that the
average duration of vertigo for people who suffer
from it has decreased since the drug was introduced.
However, during a recent three-month shortage of
the drug, there was no significant change in the
average duration of vertigo. Thus, we can conclude
that the drug has no effect on the duration of vertigo.
Which one of the following is an assumption
required by the argument?
(A) If a drug made a difference in the duration of
vertigo, a three-month shortage of that drug
would have caused a significant change in the
average duration of vertigo.
(B) If there were any change in the average
duration of vertigo since the introduction of
the drug, it would have demonstrated that the
drug has an effect on the duration of vertigo.
(C) A period of time greater than three months
would not have been better to use in judging
whether the drug has an effect on the
duration of vertigo.
(D) Changes in diet and smoking habits are not
responsible for any change in the average
duration of vertigo since the introduction of
the drug.
(E) There are various significant factors other than
drugs that decrease the duration of vertigo
for many people who suffer from it.
Correct Answer: A
A Necessary Assumption
The author disagrees with the doctors who believe that a specific drug reduces the duration of episodes of vertigo, concluding that the drug has no effect on the duration of vertigo. The author cites the three-month shortage of the drug, during which there was no significant change in the average duration of vertigo, as evidence. The answer choice will indicate the drug’s effects would have worn off within three months.
A. Yes. This states that the reduction of duration of vertigo supposedly brought about by the drug would have been at least somewhat reversed in three month’s time.
B. No. Some doctors claim that there has been a reduction in the duration of vertigo. This weakens the argument.
C. No. This is close but it doesn’t go far enough. If no amount of time would have been good to use in judging whether the drug has an effect on the duration of vertigo, then three months would have been just as ineffective as five years to use in judging this.
D. No. This doesn’t address the time period wherein some people had to stop taking the drug.
E. No. This weakens the argument, if anything. If there were other significant factors that decrease the duration of vertigo, then stopping the drug for three months wouldn’t necessarily cause an increase in the duration of one’s vertigo.
Melinda: Hazard insurance decreases an individual’s
risk by judiciously spreading the risk among
many policyholders.
Jack: I disagree. It makes sense for me to buy fire
insurance for my house, but I don’t see how
doing so lessens the chances that my house will
burn down.
Jack’s response most clearly trades on an ambiguity
in which one of the following expressions used by
Melinda?
(A) judiciously spreading
(B) many policyholders
(C) risk
(D) decreases
(E) hazard insurance
Correct Answer: C
C Flaw
Melinda concludes that hazard insurance decreases an individual’s risk. Her evidence is that the risk is judiciously spread among many policyholders. Jack disagrees with Melinda’s conclusion. Jack concludes that hazard insurance makes sense but that having, say, fire insurance doesn’t seem to decrease the risk of his house burning down. Melinda and Jack are talking about different kinds of risk. Melinda is referring to monetary risk and Jack is referring to the risk of some specific event occurring.
A. No. Jack doesn’t address this part of Melinda’s argument.
B. No. Jack doesn’t address other policyholders. He’s just interested in one policyholder: himself.
C. Yes. Jack claims that the risk of his own house burning down won’t decrease if he has insurance, while Melinda speaks of the monetary risk that such events tend to bring about.
D. No. Both use this term in the same way.
E. No. Both use this expression in the same way.
- It has been suggested that a television set should be
thought of as nothing more than “a toaster with
pictures” and that since we let market forces
determine the design of kitchen appliances we can let
them determine what is seen on television. But that
approach is too simple. Some governmental control
is needed, since television is so important politically
and culturally. It is a major source of commercial
entertainment. It plays an important political role
because it is the primary medium through which
many voters obtain information about current
affairs. It is a significant cultural force in that in the
average home it is on for more than five hours a day.
Which one of the following most accurately expresses
the role played in the argument by the claim that
television is so important politically and culturally?
(A) It states a view that the argument as a whole is
designed to discredit.
(B) It is an intermediate conclusion that is offered
in support of the claim that a television set
should be thought of as nothing more than “a
toaster with pictures” and for which the claim
that we can let market forces determine what
is seen on television is offered as support.
(C) It is a premise that is offered in support of the
claim that we let market forces determine the
design of kitchen appliances.
(D) It is an intermediate conclusion that is offered
in support of the claim that some
governmental control of television is needed
and for which the claim that the television is
on for more than five hours a day in the
average home is offered as partial support.
(E) It is a premise that is offered in support of the
claim that television is the primary medium
through which many voters obtain
information about current affairs.
Correct Answer: D
D Reasoning
Some people make an analogy between a television and other kitchen appliances. These people suggest that, since we let market forces determine the design of kitchen appliances, we can let market forces determine what appears on television. The argument disagrees with this conclusion, claiming that this view is too simple, and that some government control is needed. It is too simple because television is a major source of political information and it is also a significant cultural force, as it is on for more than five hours a day in most households.
A. No. This claim supports the argument’s conclusion.
B. No. This claim is meant to discredit the claim that a television should be thought of as a “toaster with pictures.”
C. No. It does not support the claim about kitchen appliances.
D. Yes. This claim helps support the argument’s conclusion against those who think there shouldn’t be any governmental control. The claim that the television is on for more than five hours a day in the average home is meant to show that the television is so culturally important.
E. No. The claim that television is the primary medium through which many voters obtain information about current affairs partially supports the claim that television is so politically and culturally important, not the other way around.
. Earthworms, vital to the health of soil, prefer soil that
is approximately neutral on the acid-to-alkaline scale.
Since decomposition of dead plants makes the top layer
of soil highly acidic, application of crushed limestone,
which is highly alkaline, to the soil’s surface should
make the soil more attractive to earthworms.
Which one of the following is an assumption on
which the argument depends?
(A) As far as soil health is concerned, aiding the
decomposition of dead plants is the most
important function performed by earthworms.
(B) After its application to the soil’s surface,
crushed limestone stays in the soil’s top layer
long enough to neutralize some of the top
layer’s acidity.
(C) Crushed limestone contains available calcium
and magnesium, both of which are just as
vital as earthworms to healthy soil.
(D) By itself, acidity of soil does nothing to hasten
decomposition of dead plants.
(E) Alkaline soil is significantly more likely to
benefit from an increased earthworm
population than is highly acidic soil.
Correct Answer: B
B Necessary Assumption
The argument concludes that application of highly alkaline crushed limestone to the soil’s surface should make the soil more attractive to earthworms. Decomposition of dead plants makes the top layer of soil highly acidic and earthworms, which are vital to soil’s heath, prefer soil that is approximately neutral on the acid-to-alkaline scale.
A. No. This is too strong. Aiding the decomposition of dead plants doesn’t have to be the most important function performed by earthworms in order for the conclusion to follow.
B. Yes. If the limestone immediately washed off, it wouldn’t have a chance to neutralize the top layer’s acidity and so limestone application wouldn’t make the soil’s surface more attractive to earthworms.
C. No. The argument is focused on the interaction between earthworms and the soil.
D. No. The argument is focused on the interaction between earthworms and the soil.
E. No. The argument is focused on a method to make the soil more neutral, in order to make it more attractive to earthworms. It doesn’t discuss which type of non-neutral soil is more likely to benefit from earthworms.
Salesperson: When a salesperson is successful, it is
certain that that person has been in sales for at
least three years. This is because to succeed as
a salesperson, one must first establish a strong
client base, and studies have shown that
anyone who spends at least three years
developing a client base can eventually make a
comfortable living in sales.
The reasoning in the salesperson’s argument is
vulnerable to criticism on the grounds that it fails to
consider the possibility that
(A) salespeople who have spent three years
developing a client base might not yet be
successful in sales
(B) some salespeople require fewer than three
years in which to develop a strong client base
(C) a salesperson who has not spent three years
developing a client base may not succeed in
sales
(D) it takes longer than three years for a
salesperson to develop a strong client base
(E) few salespeople can afford to spend three years
building a client base
Correct Answer: B
B Flaw
This is diagrammable. Conclusion: successful salesperson → been in sales for at least three years. Evidence: successful salesperson → establish a strong client base; at least three years developing a client base → eventually make a comfortable living in sales. The argument is confusing something that is sufficient for being a successful salesperson with something that is necessary for being a successful salesperson.
A. No. The evidence states that they will eventually be successful in sales.
B. Yes. The argument claims that successful salespeople must have spent at least three years in sales, while the evidence states that, if salespeople spend at least three years in sales, they will eventually make a comfortable living in sales. It is confusing something that is sufficient for being successful in sales with something that is necessary for being successful in sales.
C. No. This is the contrapositive of the conclusion.
D. No. The argument claims that salespeople need to spend at least three years in sales, so it allows for the fact that it might take longer than three years to develop a strong client base.
E. No. The argument doesn’t make any claims as to how many salespeople are able to do this.
Jurist: A nation’s laws must be viewed as expressions
of a moral code that transcends those laws and
serves as a measure of their adequacy.
Otherwise, a society can have no sound basis
for preferring any given set of laws to all
others. Thus, any moral prohibition against
the violation of statutes must leave room for
exceptions.
Which one of the following can be properly inferred
from the jurist’s statements?
(A) Those who formulate statutes are not primarily
concerned with morality when they do so.
(B) Sometimes criteria other than the criteria
derived from a moral code should be used in
choosing one set of laws over another.
(C) Unless it is legally forbidden ever to violate
some moral rules, moral behavior and
compliance with laws are indistinguishable.
(D) There is no statute that a nation’s citizens have
a moral obligation to obey.
(E) A nation’s laws can sometimes come into
conflict with the moral code they express.
Correct Answer: E
E Inference
Pick the answer best supported by the passage.
A. No. The passage doesn’t mention the motivations of the statute-makers.
B. No. The passage claims that, in order to have a sound basis for preferring a given set of laws to any others, laws must be viewed as expressions of a transcendental moral code.
C. No. The passage suggests that the moral rules have the preferred status, not the laws. Also, the last sentence suggests that moral behavior and compliance with laws are at least sometimes distinguishable.
D. No. This is too strong. The passage doesn’t say that there is no stature that the citizens have a moral obligation to obey.
E. Yes. If the laws are to be seen as expression of a moral code that has precedence over these laws, and that measures the adequacy of these laws, then there shouldn’t be an absolute moral prohibition against the violation of statutes. What if, for example, there was a statute that wasn’t in accord with the moral code?
- An association between two types of conditions does
not establish that conditions of one type cause
conditions of the other type. Even persistent and
inviolable association is inconclusive; such
association is often due to conditions of both types
being effects of the same kind of cause.
Which one of the following judgments most closely
conforms to the principle stated above?
(A) Some people claim that rapid growth of the
money supply is what causes inflation. But
this is a naive view. What these people do
not realize is that growth in the money supply
and inflation are actually one and the same
phenomenon.
(B) People who have high blood pressure tend to
be overweight. But before we draw any
inferences, we should consider that an
unhealthy lifestyle can cause high blood
pressure, and weight gain can result from
living unhealthily.
(C) In some areas, there is a high correlation
between ice cream consumption and the
crime rate. Some researchers have proposed
related third factors, but we cannot rule out
that the correlation is purely coincidental.
(D) People’s moods seem to vary with the color of
the clothes they wear. Dark colors are
associated with gloomy moods, and bright
colors are associated with cheerful moods.
This correlation resolves nothing, however.
We cannot say whether it is the colors that
cause the moods or the converse.
(E) Linguists propose that the similarities between
Greek and Latin are due to their common
descent from an earlier language. But how are
we to know that the similarities are not
actually due to the two languages having
borrowed structures from one another, as
with the languages Marathi and Telegu?
Correct Answer: B
B Principle Match
The principle concerns correlation versus causation: that is, that persistent correlation does not conclusively prove a causal relationship because this correlation is often due to a common cause. The answer choice will be an example of this.
A. No. Supply and inflation are the same phenomenon, which is different from them having a common cause.
B. Yes. The unhealthy lifestyle is likely the common cause for both high blood pressure and being overweight, so we shouldn’t necessarily think that being overweight causes high blood pressure. This is an example of the principle in the passage.
C. No. This doesn’t propose a common cause for ice cream consumption and high crime rates.
D. No. This doesn’t propose a common cause for mood and colors worn.
E. No. This questions a proposed common cause, claiming that the two languages borrowed from each other instead.
- People who have habitually slept less than six hours a
night and then begin sleeping eight or more hours a
night typically begin to feel much less anxious.
Therefore, most people who sleep less than six hours
a night can probably cause their anxiety levels to fall
by beginning to sleep at least eight hours a night.
The reasoning in which one of the following arguments
is most similar to that in the argument above?
(A) When a small company first begins to
advertise on the Internet, its financial
situation generally improves. This shows that
most small companies that have never
advertised on the Internet can probably
improve their financial situation by doing so.
(B) Certain small companies that had never
previously advertised on the Internet have
found that their financial situations began to
improve after they started to do so. So most
small companies can probably improve their
financial situations by starting to advertise on
the Internet.
(C) It must be true that any small company that
increases its Internet advertising will improve
its financial situation, since most small
companies that advertise on the Internet
improved their financial situations soon after
they first began to do so.
(D) Usually, the financial situation of a small
company that has never advertised on the
Internet will improve only if that company
starts to advertise on the Internet. Therefore,
a typical small company that has never
advertised on the Internet can probably
improve its financial situation by doing so.
(E) A small company’s financial situation usually
improves soon after that company first
begins to advertise on the Internet. Thus,
most small companies that have never
advertised on the Internet could probably
become financially strong.
Correct Answer: A
A Parallel
The argument concludes that most people who sleep less than six hours a night can probably cause their anxiety levels to fall by beginning to sleep at least eight hours a night. The evidence is a correlation between a drop in anxiety levels of people who have habitually slept less than six hours a night but who start sleeping eight or more hours a night.
A. Yes. This concludes that most small companies that have never advertised on the Internet can probably improve their financial situation by advertising on it. The evidence is a correlation between an improvement in finances and small companies who haven’t previously advertised on the Internet starting to do so.
B. No. This is too strong. This concludes that most small companies can probably improve their financial situations by advertising on the Internet, on the basis of evidence that certain small companies improved their financial situations by doing so.
C. No. This is too strong. This concludes that it must be true that any small company that increases Internet advertising will improve its financial situation. The above argument doesn’t claim that all people will decrease their anxiety.
D. No. This claims that it is necessary for a small company to start to advertise on the Internet in order to improve their financial situation. The above argument claims that starting to sleep more than eight hours a night is sufficient for a reduction in anxiety.
E. No. This is too strong. This concludes that most small companies that have never advertised on the Internet but start doing so could probably become financially strong. The above argument claims that people’s anxiety levels might drop, not that they will become anxiety-free.
Biologist: Lions and tigers are so similar to each
other anatomically that their skeletons are
virtually indistinguishable. But their behaviors
are known to be quite different: tigers hunt
only as solitary individuals, whereas lions hunt
in packs. Thus, paleontologists cannot
reasonably infer solely on the basis of skeletal
anatomy that extinct predatory animals, such
as certain dinosaurs, hunted in packs.
The conclusion is properly drawn if which one of the
following is assumed?
(A) The skeletons of lions and tigers are at least
somewhat similar in structure in certain key
respects to the skeletons of at least some
extinct predatory animals.
(B) There have existed at least two species of
extinct predatory dinosaurs that were so
similar to each other that their skeletal
anatomy is virtually indistinguishable.
(C) If skeletal anatomy alone is ever an inadequate
basis for inferring a particular species’
hunting behavior, then it is never reasonable
to infer, based on skeletal anatomy alone, that
a species of animals hunted in packs.
(D) If any two animal species with virtually
indistinguishable skeletal anatomy exhibit
quite different hunting behaviors, then it is
never reasonable to infer, based solely on the
hunting behavior of those species, that the
two species have the same skeletal anatomy.
(E) If it is unreasonable to infer, solely on the basis
of differences in skeletal anatomy, that extinct
animals of two distinct species differed in
their hunting behavior, then the skeletal
remains of those two species are virtually
indistinguishable.
Correct Answer: C
C Assumption Sufficient
The biologist concludes that paleontologists cannot reasonably infer that extinct predatory animals hunted in packs, solely on the basis of skeletal anatomy. The biologist cites the differences between the hunting patterns of lions and tigers, whose skeletons are virtually indistinguishable. Tigers hunt alone, while lions hunt in packs. The credited response will strengthen the analogy between tigers and lions, on the one hand, and the skeletons of extinct predatory animals, on the other.
A. No. The skeletons themselves don’t need to be similar. The important part of the analogy is the similarity in the skeletons of creatures and their difference in hunting habits.
B. No. This doesn’t address the difference in hunting habits.
C. Yes. The biologist claims that skeletal anatomy alone is an inadequate basis for inferring the hunting behavior of tigers and lions. So, given this answer choice, it is not reasonable to infer that extinct predatory animals hunted in packs, based on skeletal anatomy alone.
D. No. According to the argument, lions and tigers have virtually indistinguishable anatomy. Plus, the argument makes a claim about hunting behaviors based on skeletal anatomy, not the other way around.
E. No. Lions and tigers are not extinct. Also, the argument makes a claim about hunting behaviors based on skeletal anatomy, not the other way around.
- Doctor: Being overweight has long been linked with a
variety of health problems, such as high blood
pressure and heart disease. But recent research
conclusively shows that people who are slightly
overweight are healthier than those who are
considerably underweight. Therefore, to be
healthy, it suffices to be slightly overweight.
The argument’s reasoning is flawed because the
argument
(A) ignores medical opinions that tend to lead to a
conclusion contrary to the one drawn
(B) never adequately defines what is meant by
“healthy”
(C) does not take into account the fact that
appropriate weight varies greatly from person
to person
(D) holds that if a person lacks a property that
would suffice to make the person unhealthy,
then that person must be healthy
(E) mistakes a merely relative property for one
that is absolute
Correct Answer: E
E Flaw
The doctor concludes that being slightly overweight is sufficient to be healthy. The doctor cites recent research that conclusively shows that people who are slightly overweight are healthier than those who are considerably underweight. He bases an absolute—being healthy—on a comparison: which of two groups of people is healthier.
A. No. The doctor acknowledges the previous medical opinions to the contrary but thinks that the new evidence supports his own conclusion.
B. No. This is never the credited response.
C. No. The doctor never discusses absolute numbers in terms of people’s weights.
D. No. The doctor never discusses a property that would be sufficient to make people unhealthy.
E. Yes. Being healthier is a merely relative property, while being healthy is an absolute property.
