Final answer:
Olivia is impressed with Megan's performance in field hockey, yet she chooses not to follow in her footsteps to find her own path to success. The correct option regarding Olivia's feelings is A) Impressed.
Step-by-step explanation:
Olivia's feelings towards her sister Megan's performance on the hockey field can be understood through the narrative provided. It is clear that Olivia is impressed with her sister's abilities to dominate in the sport, as indicated by the text. The fact that Olivia 'stood among the cluster of students watching her older sister' suggests that she observes Megan's games and has a certain level of admiration for how Megan plays.
Despite her enthusiasm for the sport, Olivia is reluctant to pursue field hockey herself due to her concerns about being in her sister's shadow. This detail is important because it shows that Olivia's feelings are positive towards her sister's prowess in hockey but mixed when considering her own participation in the sport. She is seeking her own area to excel in, separate from her sister's achievements.
Therefore, the correct option that reflects Olivia's feelings about Megan's performance is A) Impressed. Olivia's admiration for her sister's skills on the field is evident, even as she reflects on her personal decision not to pursue the same sport in order to avoid a direct comparison with Megan's success.
