Passage:

At thirteen, Imani kept a small notebook of promises. The first pages were crowded with vows she made to herself: to speak up, to refuse unfairness, to never apologise for other people's impatience. Years later, the notebook lay in a drawer beneath unpaid bills. When her manager raised his voice, Imani laughed softly and said, "Of course. I understand." That night, she opened the drawer, saw the notebook, and slid it back without reading a line.

Which choice best describes how the passage develops Imani's character?
