premise: A man wearing a snorkel and goggles gives a thumbs up as he and another person speed through the water.
hypothesis: There are two guys above the water.
explanation_1: The other person means there are not necessarily two guys and it could be a guy and a girl.
explanation_2: We cannot tell if both of the people snorkeling are guys.
explanation_3: Because there are two men above water does not imply that they are snorkeling
