7sage LSAT Flashcards
Neither nor means?
Neither nor=not 1 AND not the other
only has 1 meaning! yay
What do you do if one sentence has group 3 AND group 4 indicators?
As it happens, you can just blindly apply Group 3 translation or Group 4 translation and get to the same results. You just have to remember to use the other “logical indicator” as a negation.
REMEMBER whichever word you chose as the logical indicator, the other word acts as a negation (a /)
Word you are using to identify group number is NOT a negation
Group 4 logical indicators? Rule?
Group 4 logical indicators: no, none, not both, never, cannot
Group 4 rule: You pick either idea, then negate that idea, then make that idea the necessary condition.
Group 3 logical indicators? Rule?
Group 3 logical indicators: unless, until, or, without
Group 3 rule: You pick either idea, then negate that idea, then make that idea the sufficient condition.
Group 2 logical indicators? Rule?
Group 2 logical indicators: only, only if, only when, only where, always, requires, must, will
Group 2 rule: the idea immediately following the logical indicator is the necessary condition.
Group 1 logical indicators? Rule?
Group 1 logical indicators: if, when, where, all, the only, every, any
Group 1 rule: the idea immediately following the logical indicator is the sufficient condition (sufficient is on left of arrow)
What are the components of Lawgic?
[Sufficient Condition] → [Necessary Condition]
two ways to express this, called contrapositives: J–> F AND /F –> /J
–> = implies
/ = not
Differences and similarities between MSS and MP question?
MP and MSS questions are similar bc both ask you to identify the conclusion
MP questions-conclusion is in the stimulus
MSS questions-conclusion is in the answer choices
answer choices only includes one answer with any support at all; all others are totally usnupported–> the one with support is your answer
These questions can either use the whole stimulus as support for conclusion OR one or two parts of stimulus as support for support conclusion (for latter, you will have to ignore parts of stimulis that are not relevant to conclusion)
Words or phrases that are usually followed by premise(s) but contain the conclusion?
For, Since, Because ALWAYS introduces premises
BUT that same sentence will have the conclusion present as well
Conclusion will be either before or after ‘for, since, because’
Why is “Or” So Confusing?
“Or” and “either or” are confusing. They have three different meanings.
The “inclusive or” meaning “and/or”-GROUP 3!
The “exclusive or” meaning “or, but not both”
Simply “and”
The “inclusive or” is the version of “or” we include in the Group 3 translations because it is the one used most commonly on the LSAT.
Examples:
(1) Jon enrolls in either Economics 101 or Political Science 101 this semester.
and/or – John enrolls in E or PS
and meaning is very rare in LSAT; it is typically or
(2) You may sit either at one end of the table or the other end.
or, but not both! – sit @ one end OR other end (not both)
(3) Jane is a faster eater than either Mary or Jon.
And! – faster than mary AND John
can identify if it follows the format of ‘faster than x or y’
