premise: A curly-haired man and a woman in a black tank top both play guitars and sing at a festival.
hypothesis: A brother and sister are playing in their band at a festival.
explanation_1: A man and woman can play instruments and sing at a festival without being brother and sister.
explanation_2: A man and a woman are not necessarily brother and sister. Just because the man and woman both play guitars and sing at a festival does not mean they're in a band together.
explanation_3: Not all men and women are brother and sister.
