LSAT Practice Test

Which statement contradicts the incorrect diagram AB --> -B-C-?

1. A sits next to B, then B sits next to C

2. A does not sit next to B

3. B sits next to A, then C is not next to B

4. B sits next to C

The correct answer is: A sits next to B, then B sits next to C

In the diagram AB --> -B-C-, the arrow pointing towards -B- indicates that B cannot sit in those seats. Therefore, statement A, "A sits next to B, then B sits next to C," contradicts the diagram because it suggests that A and B are sitting next to each other, which is not possible based on the restriction in the initial diagram. Therefore, statement A is the correct answer. Statement B is consistent with the diagram since it says "A does not sit next to B," which aligns with the restriction in the diagram. Statement C is also consistent with the diagram as it says "B sits next to A, then C is not next to B," which follows the given constraints. Statement D contradicts the diagram because it states "B sits next to C," but the diagram shows that B cannot sit in the -B- seats.
