premise: A group of men are searching for something.
hypothesis: A group of men are using flashlights to find something.
explanation_1: We have no idea if they are using flashlights or not, they could just be looking.
explanation_2: Just because men are searching for something does not mean they are using flashlights.
explanation_3: When trying to find something, one does not always search in the dark and so there will be no need to be using flashlights.
