Hey there. Sounds like an interesting story..
I would probably chose B as the best choice since it summarizes the main points of the story. A is the second best choice, but it only mentions the guitar. C and D both miss major parts of the story, only mentioning the clothes and shopping. Hope this helps you out. :D
Answer: Nothing but their children’s deaths could stop the parents’ anger.
What these lines state is that the parents' feud was continuous, and that, besides the children dying, nothing could stop it. In other words, nothing but the children's deaths could stop the parents' anger. This is true as we reach the end. It is only after the tragic death of Romeo and Juliet that the Capulet and the Montague are able to end their feud and leave their hate behind.
The answer would be the fourth one. She is upset.
