LSAT Logic Games: Sequencing and Ordering Games 5 — Questions and Answers
Question 1: A sequencing game has seven slots. Variables include J, K, L, M, N. Constraint: K is in an earlier slot than both J and L. If K is in slot 4, which of the following must be true?
- J and L are both in slots 5, 6, or 7. (Correct answer)
- J is immediately after K.
- L is in slot 7.
- J is in a later slot than L.
Correct answer: J and L are both in slots 5, 6, or 7.
K in slot 4 means both J and L must come after position 4, so they must each be in slot 5, 6, or 7.
Question 2: In a sequencing game, 'P is somewhere between Q and R' (not necessarily adjacent) means:
- Either Q<P<R or R<P<Q in the ordering. (Correct answer)
- P is immediately between Q and R.
- Q is before P and P is before R.
- P is before both Q and R.
Correct answer: Either Q<P<R or R<P<Q in the ordering.
'Between Q and R' means P is after one and before the other, in either direction: Q…P…R or R…P…Q.
Question 3: Five city inspections are scheduled Monday through Friday. Rules: City A is inspected before City B; City C is inspected on Wednesday; City D is inspected on the day immediately before City E. If City B is inspected on Friday, which day is City A inspected?
- Monday, Tuesday, Wednesday, or Thursday
- Monday or Tuesday only
- Thursday only
- Monday, Tuesday, or Thursday (Correct answer)
Correct answer: Monday, Tuesday, or Thursday
A must be before B (Friday), so A can be Mon–Thu; but C is fixed on Wednesday, so if A is Wednesday then A=C which is impossible, leaving Mon, Tue, or Thu for A.
Question 4: In a sequencing game with nine positions, two variables X and Y have the constraint 'X and Y are separated by exactly one position.' Which of the following slot pairs for (X, Y) satisfies this constraint?
- (3, 5) (Correct answer)
- (4, 6)
- (2, 4)
- (5, 7)
Correct answer: (3, 5)
Separated by exactly one position means |X − Y| = 2 (one position between them), so (3, 5) has positions 3 and 5 with exactly one slot — position 4 — between them.
Question 5: In a LSAT ordering game, when a question asks 'Which of the following, if true, would most restrict the ordering?' you should:
- Select the answer that, combined with existing constraints, leaves the fewest valid orderings. (Correct answer)
- Select the answer that adds the most variables to the game.
- Select the answer that creates the longest chain of ordered variables.
- Select the answer that fixes the most variables to specific positions.
Correct answer: Select the answer that, combined with existing constraints, leaves the fewest valid orderings.
The most restrictive additional constraint is the one that, when combined with existing rules, minimizes the number of remaining valid complete orderings.
Question 6: A sequencing game places six employees — P, Q, R, S, T, U — in positions 1–6. R is before S. T is before U. Q is last. If S is immediately after R, and U is immediately after T, which of the following is a valid first-position occupant?
- P or R or T (Correct answer)
- Q only
- S or U
- R only
Correct answer: P or R or T
Q is fixed in position 6; R-S and T-U are consecutive pairs; the first position can be R (with S in 2), T (with U in 2), or P — any of these three.
Question 7: In an LSAT sequencing game, a 'floater' variable is best described as:
- A variable with no constraints linking it to other variables. (Correct answer)
- A variable that can only occupy the first or last position.
- A variable that must be placed in the middle of the sequence.
- A variable involved in the most constraint relationships.
Correct answer: A variable with no constraints linking it to other variables.
A floater is a variable not mentioned in any constraint, giving it maximum positional flexibility.
