Long-distance runners use two different kinds of cognitive strategies: "associative" and "dissociative." Associative...

Hi LSATMAX, I am struggling with this question and need help figuring out how I would select A if a similar question were to be on the test. It seems as though the LSAC board is very specific with language, and throughout the LSATMAX course, the tutors continuously touch on the importance of language. In this case, the stimulus is specific to point out that associative strategies could leave the runner mentally exhausted for a day OR LONGER. The correct answer is specific to talk about the DAY before the race. It seems as though this language overlaps. If one strategy has the potential to leave the runner exhausted the day of the race, why would we select that answer? I originally selected E, and I understand the passage does not discuss which one is more 'effective', but how is it not the better answer? If this were to be on a test and I was between A and E, how would I know to select A? "Since it's important to for runners to enter the race mentally refreshed"... implies that its asking which strategy would be most effective before a race. While associative strategies may have other benefits, can we not properly conclude that any strategy that could disrupt the runner a day before the race is not a good conclusion?
