premise: A group of men with cowboy hats are watching a rodeo.
hypothesis: A group of women are watching a horse race
explanation_1: A group of men can not also be a group of women while a rodeo involves a variety of animals and events as opposed to a horse race which is just horses running.
explanation_2: A group of men are not women.  Watching a rodeo is not the same as watching a horse race.
explanation_3: The men are different from the women.
