premise: A group of young people with instruments are on stage.
hypothesis: People are playing music.
explanation_1: The young people could just be displaying the instruments, having an instrument and playing music are different things.
explanation_2: The group has instruments and are on a stage, but nothing shows that they are playing the instruments.
explanation_3: Just because a group of young people with instruments are on stage doesn't mean they are playing music.
