premise: A boy in a blue shirt, a girl in a white shirt, a man in a black shirt and black cap, and a goateed man in a white shirt stand next to an inflatable slide while a boy in a white shirt and jeans bounces downwards. hypothesis: The four people screamed in horror as the young boy was hurled off the inflatable slide, flying through the air.
neutral: It is not implied that the people are screaming. Just because the boy is bouncing downwards, does not mean he is going down a slide, about to be hurled off into the air.
