premise: A woman with short blond-hair smiling and singing into a microphone while a man in a striped shirt, further back, plays an acoustic guitar.
hypothesis: A woman is singing a Britney Spears song with her brother
explanation_1: A woman singing with a man does not imply it is her brother or that they are playing a Britney Spears song.
explanation_2: Just because a woman with short blond-hair smiling and singing into a microphone while a man in a striped shirt, further back, plays an acoustic guitar does not mean she is singing a Britney Spears song.
explanation_3: Not all songs are a Britney Spears song.
