premise: A man and a woman are holding hands on the shore of a lake.
hypothesis: A couple on vacation.
explanation_1: A man and woman are not assumed to be a couple.  Being on the shore of a lake does not necessarily mean they are on vacation.
explanation_2: We have no idea if they are on vacation, they might be at home.
explanation_3: Just because a man and a woman are holding hands does not mean they are a couple.
