Answer to Question 1

ANS: A
The medulla oblongata, not the pons, controls reflex activities, such as heart rate, respiration, blood pressure, coughing, sneezing, swallowing, and vomiting. The midbrain is primarily a relay center for motor and sensory tracts, as well as a center for auditory and visual reflexes. The cere-brum plays a role in the transfer of information.

Answer to Question 2

ANS: A
Blockage of the cerebral aqueduct leads to hydrocephalus. Hydrocephalus is not a result of dys-function of the inferior colliculi, red nucleus, or tegmentum.

Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
