premise: A man in a blue shirt, blue jeans, and a red apron standing at a grill.
hypothesis: A man in blue jeans cooks hot dogs on the grill.
explanation_1: We do not know he is cooking hot dogs because the food item is never described in sentence 1.
explanation_2: Not everyone cooks hot dogs every time they use the grill.
explanation_3: Standing at a grill does not necessarily mean a person cooks. There are a number of other items that could be on a grill besides hot dogs.
