LSAT (Law School Admission Test)Analytical ReasoningEasy
An art exhibition features six paintings—F, G, H, I, J, K—arranged in a single row of six display slots, numbered 1 through 6 from left to right. Each slot must contain exactly one painting. The arrangement is subject to the following conditions: Painting F must be in an earlier slot than Painting I. Painting H must be in a slot immediately adjacent to Painting K. Painting G cannot be in Slot 1. Painting J must be in Slot 3. If Painting K is in Slot 4, which of the following must be true?
- APainting I is in Slot 6.
- BPainting G is in Slot 6.
- CPainting F is in Slot 2.
- DPainting H is in Slot 5.
Show answer & explanationAnswer & explanation
Correct answer: D. Painting H is in Slot 5.
If J is in Slot 3 and K is in Slot 4, then H must be in Slot 5 to be immediately adjacent to K, as it cannot be in Slot 3 (occupied by J). This directly places H.
Why the other options are wrong
- A. I must be after F. I could be in Slot 2 (if F is in Slot 1 and G, H, K, J are arranged appropriately, which isn't the case here, but I could be in P6 or P2, P5). If F is in Slot 1, I could be in Slot 2. If F is in Slot 2, I could be in Slot 5. So I is not necessarily in Slot 6.
- B. G cannot be in Slot 1. G could be in Slot 2 (e.g., F-G-J-K-H-I).
- C. F could be in Slot 1 (e.g., F-G-J-K-H-I).
Deduction from Fixed Positions
Inferring necessary truths or impossible scenarios based on established positions of elements and their rule interactions.
- Start with the most constrained elements.
- Apply rules sequentially to derive new certainties.
- Check all remaining spots for consistency.
