(obsolete) LSAT GAMES translating prompt language to symbols and rules

Question 1

Symbolizing Not Both, Either

Symbolizing Both, Neither

Answer 1

See attached. Also note that while Both and Neither make simple intuitive sense, remember that Not Both and Either can be less intuitive.

Memorize: Not Both = AT LEAST ONE IS NOT

Memorize: Either = AT LEAST ONE IS

Question 2

ALL people who attend Jeff’s party will attend Kathryn’s party EACH person who attends Jeff’s party will attend Kathryn’s party

Answer 2

J –> K All and Each refer to TRIGGER

Question 3

Brennan will attend EVERY session that Kendall will attend ANY session that Kendall will attend, Brennan will attend

Answer 3

K –> B Every and Any refer to TRIGGER

Question 4

Johnny will drink beer ONLY IF Sally will also

Answer 4

J –> S Yes, counter-intuitive. ONLY IF is like a “then”. Refers to RESULT. Adding “only” to “if” to create “only if” is very impactful and changes everything. So don’t confuse them.

Question 5

ONLY students who attend the boat party will attend the dance

Answer 5

D–>B Yes, kind of weird. ONLY is like a “then”. Refers to RESULT.

Question 6

Lauren must prepare lunch UNLESS Amy does.

Answer 6

~A –> L Unless simply means “if not” and refers to TRIGGER

note that “without” means “unless” aka if not

note that “except” means “unless” aka if not

Question 7

Bill will bring his wife to the party IF AND ONLY IF his daughter will attend (same as IF BUT ONLY IF)

Answer 7

D –> W –> D, which is same as W–>D–>W It’s like two rules in one. Remember how “only if” is basically like a “then”? So whatever is being referred to in sentence (Daughter in this case) becomes a TRIGGER and a RESULT. But also notice the other reference (Wife in this case) is also becoming TRIGGER and RESULT. So everything becomes everything.

Question 8

Answer 8

Question 9

Sequencing Fiona bungees before Gunther or after Happy, BUT NOT BOTH

Answer 9

Gangsta Rule w/ F on Points

Question 10

What do each, any, every, and all mean?

Answer 10

If – very impt – see PT 45 photographs game

Question 11

How do you write in a selection game language like “if the P is included, P is yellow?”

Answer 11

Try to incorporate rules directly into diagram, do not write as if-then w/ subscripts. Do not write P–>P_G. Too complicated.

Instead just write ~P on diagram for the other colors.

Question 12

Answer 12

LU –> ~L_M/~U_M

Note: “at least one” when referring to two entities is the same as EITHER OR

Answer 13
