I'm confused. If the question stem doesn't say to find the "pattern" and be like "the reasoning is most similar to", then the AC could be ordered in a different way than the stimulus did?

I choose D for 7 because I've mistaken the question as NA (or SA) question. If it was, would D then be the answer? Because if we negate the D to "some people in the control group experienced a rise in body temperature just before bedtime", this would hurt the researcher's argument that working out in the afternoon helps deep sleeping by pointing out that even if you don't workout in the afternoon, you can get deep sleep.
