premise: A man wearing an apron is smiling at a plate of food.
hypothesis: The man is happy by the sight of the food before him.
explanation_1: Since the man is smiling at a plate of food, that food must be before (in front of) him; smiling is typical of a happy mood; food is usually more significant than the plate it is on, so the smiling is probably regarding the food specifically; the sight of food can make a man happy.
explanation_2: When someone is happy they tend to smile to show that they are happy. The plate is a plate of food, therefore the man has the sight of food before him.
explanation_3: Being happy is a consequence associated by the action of smiling. Man and food are the same in both sentences.
