Denny asked: Premise: "A young male practicing tricks with his skateboard on a cement curb."
Hypothesis: "A young man is skateboarding in a skate park."
Do we know that the hypothesis entailed by the premise?.
Le: OK, so how can I answer with some explanation?

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

A man can skateboard and not be in a skate park.
The answer: it is not possible to tell.
