A person outside the gravitational field of Earth experiences disruption of normal functions of the inner ear. The region of the brain processing the disruption and the ability affected by this disruption are, respectively the A. cerebellum and the ability to walk a straight line B. cerebrum and the ability to write legibly C. cerebellum and the ability to hear D. cerebrum and the ability to speak

The inner ear plays a crucial role in maintaining balance and spatial orientation. When a person is outside the gravitational field of Earth, such as in space, the lack of gravity can disrupt the normal functions of the inner ear, leading to issues with balance and coordination.<br /><br />The region of the brain that processes information related to balance and coordination is the cerebellum. Therefore, the disruption of normal functions of the inner ear would primarily affect the cerebellum.<br /><br />The ability affected by this disruption would be related to balance and coordination, such as the ability to walk a straight line.<br /><br />Therefore, the correct answer is:<br />A. cerebellum and the ability to walk a straight line
