premise: Two men look over a hole in the ground with pipes and hoses coming out.
hypothesis: The workers are fixing the sewer.
explanation_1: Just because two men are looking over a hole in the ground with pipes and hoses coming out doesn't mean they are workers who are fixing the sewer. They could be strangers who happen upon a hole in the grounds and look into it out of curiosity.
