Student: Premise: "The man in the red jacket is taking a nap outside on a raised concrete wall."
Based on this premise, can we conclude that the hypothesis "A man is leaning on  a wall." is true?
Options:
- yes
- it is not possible to tell
- no.
Teacher: Let's think:
A man is leaning on a wall is not necessary to be in red jacket. So the final answer is it is not possible to tell.
