premise: A very large man in a jacket and woolen cap is talking on his cellphone while other pedestrians walk by him. hypothesis: The overweight man has lost his car keys and is calling his wife to help him.
neutral: Just because a man is very large it doesn't mean he is overweight just that he is very large. You also have no evidence he lost his car keys and is calling his wife to help him. He may not even have a car.
