premise: A man with a gray beard and an apron smiles.
hypothesis: A grandfather smiling while baking
explanation_1: The man does not have to be a grandfather and just because he has on an apron does not mean he is baking.
explanation_2: Just because the man had a gray beard doesn't mean that he was a grandfather as well as an apron doesn't necessarily mean that he was baking.
explanation_3: Just because the man has a gray beard does not mean he's necessarily a grandfather. Just because he's wearing an apron does not mean that he's necessarily baking.
