Leo: Premise: "A man holding a screwdriver and wearing a t-shirt and baseball cap sits on the ground with a young boy looking at a outdoor grill."
Hypothesis: "The man is trying to fix the grill."
Do we know that the hypothesis entailed by the premise?
Mei: OK, So, let's think first...
Me:
A person can be looking at a grill but not be trying to fix the grill.
Thus, the answer is it is not possible to tell.
