premise: Outdoors in front of a crowd, a man plays an instrument by blowing into pipes he holds up to his face.
hypothesis: An old man playing an instrument for a bunch of boyscouts at an outdoor concert.
explanation_1: The man could be any age. Also, just because he is playing an instrument, does not mean he is doing so for a bunch of boyscouts at an outdoor concert. He could be playing for anyone, anywhere.
explanation_2: The first sentence doesn't specify to whom or what venue the man is playing his instrument. We cannot assume that he is performing for boyscouts at an outdoor concert.
explanation_3: Just because outdoors in front of a crowd, a man plays an instrument by blowing into pipes he holds up to his face, doesn't mean he is old.
