Read this passage from “Two Kinds.” Here, the narrator explains how she began reacting to her mother’s quizzes.
"I had new thoughts, willful thoughts, or rather thoughts filled with lots of won’ts. I won’t let her change me, I promised myself. I won’t be what I’m not.
So now on nights when my mother presented her tests, I performed listlessly, my head propped on one arm. I pretended to be bored. And I was."
Which sentence best explains what drives, or motivates, the narrator to act bored?
