premise: A young man is playing a blue guitar.
hypothesis: A musician practices on his guitar briefly before a concert.
explanation_1: this young man could play the guitar without being a concert musician
explanation_2: It is not necessary for man to be a musician to play guitar. Playing guitar doesn't necessarily mean doing practice on guitar. A young man is playing a blue guitar doesn't imply that he is practicing on his guitar briefly before a concert.
explanation_3: Just because the man is playing a guitar does not mean that he is a musician.
