Hypothesis: "A man plays chess with his son."

Student asked: Premise: "A man in a black vest standing in the middle of a crowd with his hands on his hips."
Based on this premise, can we conclude that the hypothesis "A man hurt his hip while standing in a crowd trying to find help." is true?
Options:
- yes
- it is not possible to tell
- no
Teacher's response:
Let's think. Placing his hands on his hip does not imply that the man's hip hurts. A man can have his hands on his hips if they are healthy or if they hurt. The answer is it is not possible to tell.
