Consider the question. Can we conclude from "Two pairs of legs walk past the end of an alley between two brick buildings." that "A person walks past two brick buildings."?
Options:
- yes
- no
- it is not possible to tell
 If the answer is 'it is not possible to tell'; explain the reasoning:
Sentence 1: Two pairs of legs walk past the end of an alley between two brick buildings. Sentence 2: A person walks past two brick buildings.
