premise: Two children are sleeping while someone is fingering through a book of music.
hypothesis: The music is quiet.
explanation_1: Just because someone was fingering through a book of music. There's is no way that you could hear how quiet the music was.
explanation_2: As looking through a book of music does not make noise, the music could be of any intended volume and it would not affect the children's ability to sleep.
explanation_3: We do not know music is quiet. We only know that someone is looking through a book of it.
