Answer to Question 1

B
Sleep requirements are most accurately determined by going to bed at the usual time and waking up without an alarm for several nights, ideally on vacation. The average of these findings indicates the estimated requirements. Two distracters relate to dream content and daytime alertness. Some adults are long sleepers or short sleepers with different requirements for sleep from the general population.

Answer to Question 2

A
The master biological clock in the suprachiasmatic nucleus (SCN) of the hypothalamus regulates sleep as well as other physiological processes. Darkness cues the clock for sleep. Light cues it for wakefulness. Light stimulates retinal messages. Histamine release is associated with wakefulness. Stimulation of the sympathetic nervous system promotes alertness.
