For the first question the best quote emphasising the power of his music would be “His songs were so sad that no human could bear to listen to them”. As in they moved people to the point it hurt them to listen, because his music was that powerful. The first and second answer choice are just saying he’s skilled but not necessarily that it’s powerful and then the last answer choice isn’t saying anything about the music just that he was singing.
The other one I’m not as sure of but I believe it would be showing the strength of his love for his wife, it could be the second one but I would say it wasn’t. The last answer choice is to literal and it can’t be comparing his life to a life without his wife’s love because it isn’t a simile or a metaphor which are for comparisons.
