premise: A man wearing a hat sitting on the side of a hill looking towards the water.
hypothesis: The man is watching boats pass by while sitting on the hill.
explanation_1: The man could be looking at anything in the water, not necessarily watching boats.
explanation_2: Watching water does not mean there are boats in the water.
explanation_3: The man is near water but that doesn't mean he is watching boats and he might be sitting on a bench not the hill itself.
