Student asked: Test for natural language inference.
Premise: "A man smithing in a shop."
Hypothesis: "A man is writing a letter at his desk."
Is the hypothesis entailed by the premise?
Options:
- yes
- no
- it is not possible to tell
Teacher's response: Let's think. A man who is smithing cannot also be writing a letter. One cannot be in a blacksmith shop and at a desk simultaneously. The answer is no.


Student asked: Given the sentence "Man holds the hand of two children." is it true that "The man is cooking a meal."?
Teacher's response: Let's think. He can't hold hands and cook a meal at the same time. The answer is no.


Student asked: Can we conclude from "A man fishing while standing on a small boat holding a net." that "The boat is made out of steel."?
Options:
- yes
- no
- it is not possible to tell
Teacher's response: Let's think. A small boat does not imply it is made out of steel. The answer is it is not possible to tell.


Student asked: If "A boy jumps into a pool while lifeguards watch." does that mean that "A boy sunbathes at the pool."?
Options:
- yes
- it is not possible to tell
- no
Teacher's response:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
