Researcher: We studied two groups of subjects over a period of six months. Over this period, one of the groups had a daily routine of afternoon exercise. The other group, the control group, engaged in little or no exercise during the study. It was found that those in the exercise group got 33 percent more deep-sleep at night than did the control group. Exercising in the afternoon tends to raise body temperature slightly until after bedtime, and this extra heat induces deeper sleep.

Summary

Over six months, two groups were studied. One group exercised in the afternoon every day. The other group had little or no exercise. The people in the group that exercised were found to have 33 percent more deep-sleep compared to the group that had little or no exercise. Researchers hypothesize this is because afternoon exercise raises the body temperature slightly until after bedtime, which induces deeper sleep.

Strongly Supported Conclusions

Other activities that raise a person’s body temperature slightly before bedtime may cause that person to have increased levels of deep-sleep.

A
Regular afternoon exercise is one of the things required for adequate deep-sleep.

This answer is unsupported. Saying that regular afternoon exercise is “required” for adequate deep-sleep is too strong. We only know from the stimulus that afternoon exercise can increase deep-sleep.

B
Exercise in the morning is almost as likely to have as many beneficial effects on sleep as is exercise in the afternoon.

This answer is unsupported. The Researcher’s study is limited to exercise performed in the afternoon. We don’t know from these results what effects morning exercise could cause, if any.

C
The best way to get increased deep-sleep is to induce a slight increase in body temperature just before bedtime.

This answer is unsupported. We don’t know from the stimulus whether a slight increase in a person’s body temperature is the “best way” to get increased deep-sleep. There could exist many other methods for this same effect.

D
No one in the control group experienced a rise in body temperature just before bedtime.

This answer is unsupported. It could be true that one or two people in the control group experienced a rise in body temperature, but that doesn’t change the 33 percent increase in deep sleep for the group that exercised.

E
Raising body temperature slightly by taking a warm bath just before bedtime will likely result in increased deep-sleep.

This answer is strongly supported. The Researcher hypothesizes that the rise in body temperature is the cause of increased deep-sleep for the people in the study. Exercise is one method for achieving this effect, but there are likely to be others.
