Student: Premise: "People are walking past a young man in a red shirt and khaki shorts."
Hypothesis: "A man sitting on the sidewalk with people walking by."
Is the hypothesis entailed by the premise?
Options:
- yes
- it is not possible to tell
- no.
Teacher: Let's think:

The young man may not necessarily be sitting on the sidewalk as people walk past him. So the final answer is it is not possible to tell.
