Consider the question. Premise: "A robust man with his mouth open in a white shirt and glasses holding a drink near other people."
Hypothesis: "A robust man is drinking a beer."
Is the hypothesis entailed by the premise?
Options:
- yes
- it is not possible to tell
- no
 If the answer is 'it is not possible to tell'; explain the reasoning:
A robust man with his mouth open in a white shirt and glasses holding a drink near other people does not mean that he is drinking a beer.
