Premise: "A person wearing dark clothes is standing on one leg in snow while a small dog is jumping in front of her."
Hypothesis: "A person stands on one leg because her foot hurts."
Do we know that the hypothesis entailed by the premise? Now, let's be accurate as possible. Some thinking first:
A person might be standing on one leg for a reason other than that his or her foot hurts. Not every person is a woman. So, the answer is it is not possible to tell.
