Final answer:
Amaya's difficulty with balance and coordination suggests that her cerebellum was likely damaged in the car accident.
Step-by-step explanation:
If Amaya has difficulty with balance and coordination after sustaining a head injury, the part of her brain that was likely damaged is the cerebellum. T
he cerebellum is a hindbrain structure that controls our balance, coordination, movement, and motor skills and is also thought to be important in processing some types of memory.
Damage to the cerebellum can result in a loss of motor control and can affect balance, leading to problems with activities that require fine motor skills, such as walking or picking up objects.
