Denny asked: Premise: "Two men sit together with their mouths open for an unknown reason."
Hypothesis: "Two men want to say something to one another but they don't know what."
Do we know that the hypothesis entailed by the premise?.
Le: OK, so how can I answer with some explanation?
Mouths open does not mean want to say something but don't know what.
The answer: it is not possible to tell.
