premise: A man dances with a woman in a white egyptian costume.
hypothesis: A couple dances in a competition.
explanation_1: Just because a couple dances in costume doesn't mean they are in a competition
explanation_2: the man and woman may not be a couple
explanation_3: A man can be in close proximity to a woman and they may be a couple or they may not be a couple, so it is not certain that they are a couple; people may dance while they are in a competition or people may dance when they are not in a competition, so one cannot be certain if they are dancing in a competition or not.
