Randall's thoughts and actions change significantly from the beginning to the end of the story. The two answers that correctly reflect this transformation are:
A) He goes from envying Starks to feeling sympathy for him.
B) He learns that wealth does not always equal happiness.
At the beginning of the story, Randall feels intense envy toward Starks due to his wealth and popularity. However, as he gets to know Starks better during the birthday party, he starts to see that Starks is not as fortunate as he seems—he feels lonely and does not have many friends. This realization leads Randall to feel sympathy for Starks, recognizing that wealth does not guarantee happiness. By the end of the story, Randall's perspective shifts, and he feels like the lucky one for having made a new friend.
