premise: There is a woman here in a children's room, wearing a red vest, with her hand in a fake sharks mouth.
hypothesis: The woman is demonstrating a shark bite.
explanation_1: You can not infer she is demonstrating a shark bite.
explanation_2: Just because there is a woman here in a children's room, wearing a red vest, with her hand in a fake sharks mouth does not mean she is demonstrating a shark bite.
explanation_3: There is no indication that sentence one is a demonstration. The woman could be telling a story to the children. Putting your hand in a fake sharks mouth does not necessarily demonstrate a shark bite.
