Answer:
Cerebellum
Explanation:
According to my research on studies conducted by various neurologists, I can say that based on the information provided within the question the doctors will likely find Christy's problem in the Cerebellum which is located in the Hindbrain. The Cerebellum is responsible for coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity. A problem with the Cerebellum can impair movements similar to what Christy is experiencing.

The development of adaptive traits is a result of natural selection, one of the main mechanisms underlying evolutionary change.
Understanding natural selection is also becoming more and more important in real-world settings, such as resource management, agriculture, and medicine. Even among people with postsecondary physical education, studies show that natural selection is generally very poorly understood.
