LSAT Logic Games: Sequencing and Ordering Games 3 — Questions and Answers
Question 1: In a sequencing game, five events — J, K, L, M, N — occur on successive days. K occurs after J. M occurs after L. N occurs before J. Which of the following is an acceptable ordering of all five events?
- N, J, K, L, M (Correct answer)
- J, N, K, M, L
- N, L, J, M, K
- L, J, N, K, M
Correct answer: N, J, K, L, M
N, J, K, L, M satisfies N before J, J before K, and L before M with no conflicts.
Question 2: A LSAT logic game has six variables placed in order. The constraint states: 'Q is placed exactly two positions after P.' If P is placed in position 3, where must Q be placed?
- Position 4
- Position 5 (Correct answer)
- Position 1
- Position 6
Correct answer: Position 5
'Exactly two positions after P' means Q's position = P's position + 2, so 3 + 2 = 5.
Question 3: In an ordering game, seven items are ranked 1–7. Item X is ranked higher than item Y (lower number = higher rank). Item Z is ranked lower than item Y. Item W is ranked higher than item X. If W is ranked 2nd, which of the following must be false?
- X is ranked 3rd.
- Y is ranked 4th.
- Z is ranked 5th.
- X is ranked 1st. (Correct answer)
Correct answer: X is ranked 1st.
W is ranked 2nd and W>X (W has a smaller rank number than X), so X must be ranked 3rd or lower, making X ranked 1st impossible.
Question 4: In a sequencing game with conditions P→Q (P immediately before Q) and R→S (R somewhere before S), if Q is placed in position 4, which of the following CANNOT be true?
- R is in position 1 and S is in position 6.
- P is in position 3 and R is in position 5. (Correct answer)
- S is in position 5 and R is in position 2.
- R is in position 3 and S is in position 6.
Correct answer: P is in position 3 and R is in position 5.
P must be immediately before Q (position 4), so P must be in position 3; if R is also in position 3, then both P and R occupy the same position, which is impossible.
Question 5: A sequencing game places six variables in a single row. Variable A must be placed before variable B. Variable C must be placed after variable D. Variable E must be placed immediately after variable F. If F is placed in position 2, which of the following must be true?
- E is placed in position 3. (Correct answer)
- A is placed in position 1.
- D is placed before position 2.
- B is placed after position 3.
Correct answer: E is placed in position 3.
Since E must be placed immediately after F, and F is in position 2, E must be in position 3.
Question 6: In a strict ordering game, the constraint 'M is not placed adjacent to N' means:
- M and N cannot be in consecutive positions. (Correct answer)
- M must be placed before N.
- N must be placed before M.
- M and N must be separated by at least two positions.
Correct answer: M and N cannot be in consecutive positions.
'Adjacent' in LSAT sequencing games means immediately next to each other (consecutive positions), so M and N cannot occupy positions that differ by exactly 1.
Question 7: Seven variables — A through G — are ordered 1–7. The following constraints apply: C is before E; E is before G; B is before D; F is first. If G is fifth, which of the following must be true?
- C is second or third.
- E is third or fourth. (Correct answer)
- B is second.
- D is sixth or seventh.
Correct answer: E is third or fourth.
F is first, G is fifth, and C<E<G with G=5 means E can be at most 4th and at least 3rd (since C must precede E and F occupies position 1); so E is third or fourth.
