Denny asked: Premise: "An elderly man wearing a hat is reading a newspaper on a street in a city."
Hypothesis: "An old man reads a newspaper outside a diner on a city street."
Do we know that the hypothesis entailed by the premise?.
Le: OK, so how can I answer with some explanation?
The fact that the elderly man is on a street in a city doesn't imply he is outside a diner.
The answer: it is not possible to tell.
