118. According to a review of 61 studies of patients suffering from severely debilitating depression, a large majority of the patients reported that missing a night’s sleep immediately lifted their depression. Yet sleep-deprivation is not used to treat depression even though the conventional treatments, which use drugs and electric shocks, often have serious side effects.

Which of the following, if true, best explains the fact that sleep-deprivation is not used as a treatment for depression?

(A) For a small percentage of depressed patients, missing a night’s sleep induces a temporary sense of euphoria.

(B) Keeping depressed patients awake is more difficult than keeping awake people who are not depressed.

(C) Prolonged loss of sleep can lead to temporary impairment of judgment comparable to that induced by consuming several ounces of alcohol.

(D) The dramatic shifts in mood connected with sleep and wakefulness have not been traced to particular changes in brain chemistry.

(E) Depression returns in full force as soon as the patient sleeps for even a few minutes.

og中对E的解释可以理解，但是已经有进行了二次推论的感觉，即在sleep-deprivation与sleeps for even a few minutes之间架桥进行推理。依此类推的话，很多CR的选项都可算是正确了。比如，本体中可否将Keeping depressed patients awake理解为sleep deprivation，keeping awake people who are not depressed理解为other treatments to the debilitating depression，这样一来，因为实现前者难于实现后者，所以不采用前者。不知这样算否牵强？

总之，就是想请教一下：本题中选E的这种推理是否还是采用了“并非完全正确，而求最佳选项“的解题思路？

看看这里能不能有点启发。如果还是不行，再问。

不过逻辑区提问的基本原则是要先看旧贴讨论的。大部分问题旧贴讨论很详细了。省去朋友们等待回复的时间。
