The correct answer is A. She doesn't want to fail her mother
again. According to her mom, she doesn't work hard at all and will never
be the best pianist if she doesn't practice more. She is quite
disappointed with her daughter and would like her to be more successful
than she is at the moment. Jing-mei, on the other hand, feels bad about
the way her mother thinks about her, and doesn't want to disappoint her
again.
