premise: A man wearing red ski pants, a black jacket, and a white helmet is skiing down a mountain.
hypothesis: The man is near another person.
explanation_1: The first sentence does not mention any other people, you do not know he is near another person until sentence 2.
explanation_2: Just because the man is skiing down a mountain doesn't mean he is near another person
explanation_3: Someone can ski without being near another person.
