Final answer:
The excerpt shows Waverly's comfort with both Chinese and American cultures, indicating that she navigates both with ease. Therefore correct option is B
Step-by-step explanation:
The excerpt from "Rules of the Game" reveals that Waverly, the protagonist, is adept at navigating both Chinese and American cultures. The moment showing her awareness of the different age calculations in her dual cultural backgrounds suggests an understanding and acceptance of her bicultural identity rather than conflict or rejection.
Therefore, the most appropriate answer reflecting Waverly's attitude towards Chinese and American cultures would be option B: Unlike her mother, Waverly is comfortable navigating both Chinese and American cultures. This acknowledges her ability to harmonize elements of both cultures in her sense of self.
