premise: A man in a black hat, standing on the street while playing an electric guitar and singing.
hypothesis: The man has a great singing voice.
explanation_1: It is not necessarily true that he has a great voice.
explanation_2: Just because a man is playing a guitar and singing it does not mean the man has a great voice.
explanation_3: We do not know if the man has a great singing voice just that he has the ability to play the guitar and sing.
