premise: A man on stage holds a hello kitty guitar and looks to the right of the picture.
hypothesis: The man is performing in a concert.
explanation_1: A man with guitar on a stage does not necessarily mean that he is performing in a concert.
explanation_2: The hello kitty guitar is likely a kids toy, therefore wouldn't be used for performing in a concert.
explanation_3: The man could be simply holding the guitar without performing. Also, just because he is on a stage doesn't mean he is in a concert, for example he could be in a stage play.
