Question

the ability to dream is provided by the ______ system.
nervous
d. the injury is the size of a dime
b. braille
feedback

Explanation:

Dreaming is a neurological process, and the nervous system (which includes the brain and associated neural structures) is responsible for cognitive functions like dreaming. The other options (braille is a tactile writing system, the "injury size" option is irrelevant, and "feedback" is a general concept not related to dreaming's physiological basis) do not fit. So the correct term is "nervous".

Answer:

nervous
