107. According to the passage, which of the following describes a result of the way in which researchers generally conduct clinical trials?
(A) They expend resources on the storage of information likely to be irrelevant to the study they are conducting.
(B) They sometimes compromise the accuracy of their findings by collecting and analyzing more information than is strictly required for their trials.
(C) They avoid the risk of overlooking variables that might affect their fi ndings, even though doing so raises their research costs.
(D) Because they attempt to analyze too much information, they overlook facts that could emerge as relevant to their studies.
(E) In order to approximate the conditions typical of medical treatment, they base their methods of information collection on those used by hospitals.
这道题所对应的原文是：Currently, researchers collect far more background information on patients than is strictly required for
their trials—substantially more than hospitals collect—thereby escalating costs of data collection, storage, and analysis. Although limiting
information collection could increase the risk that researchers will overlook facts relevant to a study, Frazier and Mosteller contend that such risk, never entirely eliminable from research, would still be small in most studies.

我觉得正确答案A是有问题的，因为原文根本就没有说多余的information是irrelevant. 而且从某种角度上来说多余的information应该是relevant,因为limiting information collection could increase the risk

求指点

说下我的想法~~ 首先声明哈，我下面说的方法只能证明A正确，不适合在考试时用。。

首先(A)选项说的是，他们为了储存一些【有可能】与他们所进行的研究不相关的info而耗费资源

文章说的是：尽管limitting info可能会导致researchers overlook relevant info，但是F和M认为"such risk, never entirely eliminable from research"（也就是说，即使不limit info，researchers也会忽略relevant info）, would still be small in most studies（也就是说，并且忽略relevant info 的几率很小）

根据以上条件我们可以假设：
在limitting info的情况下，收集的info为100，忽略了2个relevant info
而在general情况下，收集的info为500，忽略了1个relevant info
那么，是不是会有至少399个info是irrelevant的？
这种情况应该符合选项中的【可能】吧~~

似乎是把题目复杂化了，但希望能给你点灵感~~
