premise: two men are seen talking, one man wears pink and another is sporting a t-shirt for summer school 60th anniversary.
hypothesis: Two old men talk at a family reunion.
explanation_1: A summer school's 60th anniversary does not indicate that the men were at a family reunion.
explanation_2: Not all men are old. A t-shirt for a specific event can be worn at other events, such as at a family reunion.
explanation_3: Because two men are talking does not mean they're at a family reunion.
