Teacher's response: Let's think. A man swimming with goggles is different than a boy feeding pigeons. The answer is no.

Student asked: Test for natural language inference.
Premise: "A woman in shorts and knee-high socks is walking down the sidewalk."
Hypothesis: "A man wearing a beanie cap is walking in front of the store."
Is the hypothesis entailed by the premise?
Options:
- yes
- no
- it is not possible to tell
Teacher's response: Let's think. A woman is the opposite of a man. Shorts and knee-high socks is different clothing than a beanie cap. One walking down the sidewalk does not necessarily have to be in front of the store. The answer is no.

Student asked: Premise: "A woman peeks outside a set of archaic wooden doors."
Based on this premise, can we conclude that the hypothesis "A woman checks to see if the mail man is outside her window." is true?
Options:
- yes
- it is not possible to tell
- no
Teacher's response: Let's think. Peeks does not necessarily imply that she checks for mail man. The answer is it is not possible to tell.

Student asked: Can we conclude from "An older dark-haired woman is taking a picture." that "A man is taking his wife's picture."?
Options:
- yes
- no
- it is not possible to tell
Teacher's response:
Let's think. An older dark-haired woman is not necessarily the man's wife so the man is not necessarily taking his wife's picture. The answer is it is not possible to tell.
