premise: A girl with a purple sweater and a green headband is doing classwork in a classroom.
hypothesis: A boy is scratching his name into his desk.
explanation_1: The girl is not a boy, so is a her and not a him. She's doing classwork, and therefore isn't scratching her name into her desk.
explanation_2: His refers to a boy. The same subject can't be a boy and a girl at the same time.
explanation_3: A girl doing classwork can't also be a boy scratching his name into a desk.
