ANSWER

ANS: 1
Stage 1 NREM includes the lightest level of sleep. Sensory stimuli such as noise easily arouses the person. The stage lasts a few minutes. Decreased physiological activity begins with gradual fall in vital signs and metabolism. Awakened, person feels as though daydreaming has occurred. Stage 2 NREM is a period of sound sleep. Stage 3 NREM involves initial stages of deep sleep. Stage 4 NREM is the deepest stage of sleep. It is very difficult to arouse the sleeper.
