Great discussion!
Peg_city, I think your response gets to an issue that hoffman36 raises: "the connection between waking from sleep and feeling fatigued is unwarranted." Boom! Exactly! There is no information here that suggests that the harder it is to wake from sleeping, the less fatigued you are. You're adding in a whole extra assumption to justify this choice.
As you guys have said, we're trying to figure out why doctors don't advise the patient to sleep more, even though his lack of sleep contributes to his fatigue. My first thought was, they must be afraid of some negative consequence of this advice.
(E) explains this surprising advice. If worrying about sleep can actually make sleeping harder, then advising the patient to sleep more could be counterproductive. (By the way, I can vouch for the truth of answer E!)
As for the others:
(B) is out because, okay, the first two hours do the most, but we know the lack of sleep is contributing to the fatigue, so why not sleep more?
(C) is wrong for basically the same reason: some people might need less, but we know this guy needs more.
(D) is way out of scope: we have nothing to connect nightmares to the patient's fatigue, and also, your last hour of sleep is your last hour no matter how many hours you get.
Thanks for posting, guys! I hope we're all clear now.
