premise: A man dressed in a brown shirt and tan shorts is down on one knee looking at some type of machinery.
hypothesis: The man is a repairman.
explanation_1: The man might not be repairing the machinery and therefore, he isn't necessarily a repairman.
explanation_2: Not every man looking at machinery is repairman
explanation_3: Just because a man looks at a type of machinery does not mean that he is a repairman.
