premise: A balding man with glasses stands in front of a colorful display.
hypothesis: A person is standing upright.
explanation_1: A man is a person; that a man stands establishes that a person is standing; standing is 'upright' by default; if it weren't upright there would be a verb more appropriate than 'standing'.
explanation_2: Balding man is a person, and stands is a paraphrase of standing upright.
explanation_3: The man is a person.
