premise: A little boy with a shirt, shorts and socks on, standing on the beach.
hypothesis: A boy is watching a boat float by.
explanation_1: Standing on the beach doesn't imply wathing a boat flot by.
explanation_2: Just because a boy is on the beach does not mean he is looking at the water where a boat could be floating by.   Not all beaches have boats the boy can be watching.
explanation_3: Just because on the beach does not mean watching a boat.
