What does Emmie enjoy doing in her free time?

Emmie's enjoyment of tricks and racing on her wheelchair highlights her sense of adventure and physical engagement in activities despite any challenges she may face. This choice emphasizes her resilience and ability to find joy in activities that require skill, coordination, and perhaps even a community aspect if she participates with others in racing or performing tricks. Engaging in such exhilarating pursuits can also foster a strong sense of identity and empowerment, showcasing how individuals can embrace their passions regardless of their circumstances.

The other options, while potentially enjoyable activities, do not specifically emphasize Emmie's character traits and interests in the same way that wheelchair racing does. Thus, the correct answer demonstrates her unique hobbies and personal strengths.
