premise: A man waterskies with a life jacket.
hypothesis: A lifeguard races across the water.
explanation_1: Just because a man has a life jacket doesn't mean he is a lifeguard
explanation_2: Not everyone wearing a life jacket on water is a lifeguard. A person can water ski without racing across the water.
explanation_3: Just because a man waterskies with a life jacket it does not mean he is a lifeguard or that he races across the water.
