premise: A man sits beside parked cars on a city street.
hypothesis: A man is sitting on a bench.
explanation_1: Just because someone is sitting outside doesn't mean they're on a bench.
explanation_2: There is no way to know the man is sitting on a bench because he can be sitting on anything.
explanation_3: The man might regularly sit beside the parked cars, but might not necessarily be sitting there currently. Also, sentence one does not say he is sitting on a bench. He could be sitting on the ground, or elsewhere.
