Study the following information carefully and answer the given question. Following are the observations of an experiment on ‘sleep and weight-gain’ conducted on 18 healthy adults (Ages 35 to 45) and 18 healthy adolescents (ages 7 to 17).
(A) Recurrent sleep deprivation in men increased the preferences for high-calorie foods and their overall calorie intake.
(B) Women who sleep less than 6 hours a night or more than 10 hours were more likely to gain 11 pounds (5 kilograms) compared with women who slept 7-9 hours a night.
(C) Less than 8 hours sleep in adolescents results in fatigue and less physical activity and hence leading to weight-gain. Which of the following cannot be concluded from the given findings of the research?
I. Hyperactivity in adolescents is a result of more than 7-8 hours’ sleep a night.
II. The hormone that increases the desire for high-calorie food is more active in men who don’t get adequate sleep.
