Leo: Premise: "A mother and son walk along a dirt path."
Hypothesis: "There are several people on a hike."
Do we know that the hypothesis entailed by the premise?
Mei: OK, So, let's think first...
Me:
A mother and son are not several people. The mother and may be walking along a dirt path to get from one place to another and are not necessarily on a hike.
Thus, the answer is it is not possible to tell.
