Question

the cerebellum adjusts motor activity in response to all of the following except
input from proprioceptors.
touch sensations.
equilibrium - related sensations.
input from the motor cortex.
visual information.

Explanation:

The cerebellum receives input from proprioceptors (which provide information about body position), equilibrium - related sensations (from the inner ear), input from the motor cortex (to coordinate movement), and visual information (to adjust movements based on what is seen). Touch sensations are mainly processed in other areas of the brain (like the somatosensory cortex) and are not a direct input for the cerebellum's motor - activity adjustment.

Answer:

touch sensations.
