Denny asked: Premise: "A man in a dark jacket sits at a table with a blue tablecloth smiling at a woman in a green shirt with a black zipper vest."
Hypothesis: "A man is smiling at his son."
Do we know that the hypothesis entailed by the premise?.
Le: OK, so how can I answer with some explanation?
The man cannot be smiling at a woman at the same time he is smiling at his son.
The answer: no.
