Must Be True. The correct answer choice is (E)

Here we have another fact set followed, somewhat predictably, by a Must Be True question. The researcher tells us that exercise slightly raises body temperature, that extra heat induces deeper sleep, and that those who engaged in afternoon exercise within the study got more nighttime deep sleep than did those in the control group. Answer choice (E) is supported by the researcher’s point that “extra heat induces deeper sleep.”

Answer choice (A): This answer is unsupported by the researcher, who provides that afternoon exercise is conducive to deep sleep—not necessarily required.

Answer choice (B): This answer is incorrect because the researcher does not reference morning exercise at all; there is no basis for comparison of the effects of morning versus afternoon exercise.

Answer choice (C): This answer is taken out of contention with the word “best.” Afternoon exercise appears to be one way to increase deep sleep, but there is no evidence that it is the best.

Answer choice (D): This answer concerns the control group, and all we know of this group is that they engaged in little or no exercise during the study. The stimulus provides no information about participants respective pre-bedtime body temperatures, so this answer choice is unsupported.

Answer choice (E): As explained above, this is the correct answer choice.
