Part A
The correct inference about Liesl's feelings regarding her neighbor's violin playing is:
She enjoys the distraction that the music provides.
Part B
The quotation that best supports the answer in Part A is:
"We play games and read and sleep to pass the time—sometimes there’s violin music that drifts into our room at night."
This quotation suggests that the violin music is a part of their experience on the ship, indicating that it serves as a distraction, rather than being purely annoying or a source of jealousy.
