Student: Test for natural language inference.
Premise: "A man wears glasses and pants as shadows are cast in the sun."
Hypothesis: "A man is at the park."
Is the hypothesis entailed by the premise?
Options:
- yes
- no
- it is not possible to tell.
Teacher: Let's think:

Just because shadows are cast in the sun does not mean the man is in the park. He may be at the beach. So the final answer is it is not possible to tell.
