Denny asked: Premise: "A man on a very tall unicycle entertains the crowd."
Hypothesis: "A man rides the unicycle at the fair."
Do we know that the hypothesis entailed by the premise?.
Le: OK, so how can I answer with some explanation?
A man riding a unicycle to entertain a crowd is not necessarily at the fair. He could be out on the street or at some other event.
The answer: it is not possible to tell.
