Answer:
Genevieve can best be described as
humble, meaning not overly proud or arrogant.
Explanation:
In the passage, the narrator realizes that Genevieve won the race. However, the narrator only discovers this fact after a man chases after her to give her the gold medal she won. If Genevieve were overly proud or arrogant, she would have informed the narrator of her win and not forgotten her prize. However, she did just the opposite. She downplayed her success. Therefore, choice (D) is correct.
