GWD-8-Q4一道阅读题~~求帮忙

Frazier and Mosteller assert that medical research could be improved by a move toward larger, simpler clinical trials of medical treatments. 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. Only in research on entirely new treatments are new and unexpected variables likely to arise.

Frazier and Mosteller propose not only that researchers limit data collection on individual patients but also that researchers enroll more patients in clinical trials, thereby obtaining a more representative sample of the total population with the disease under study. Often researchers restrict study participation to patients who have no ailments besides those being studied. A treatment judged successful under these ideal conditions can then be evaluated under normal conditions. Broadening the range of trial participants, Frazier and Mosteller suggest, would enable researchers to evaluate a treatment’s efficacy for diverse patients under various conditions and to evaluate its effectiveness for different patient subgroups. For example, the value of a treatment for a progressive disease may vary according to a patient’s stage of disease. Patients’ ages may also affect a treatment’s efficacy.

GWD-8-Q4 :

According to the passage, Frazier and Mosteller believe which of the following about medical research?

A.      It is seriously flawed as presently conducted because researchers overlook facts that are relevant to the subject of their research.

B.      It tends to benefit certain subgroups of patients disproportionately.

C.      It routinely reveals new variables in research on entirely new treatments.

D.      It can be made more accurate by limiting the amount of information researchers collect.

E.       It cannot be freed of the risk that significant variables may be overlooked.

我的问题是：文中标红的地方确实说了一些risk是不可能被eliminated的，但是没有说是significant variables呀。。 后面也有一句说，only in new treatment research才会有new和unexpected的variables，也没有说过significant variables会被忽视也不可避免。。。。

恳请各位帮帮忙，谢谢~~

啊,我今天才看见,最近刚好也看到这篇阅读.首先吧 ,其他几个选项都不对.再接下来,看文中,Frazier and Mosteller contend that such risk 不可能在研究中完全被消除,而这个risk,指的是前面 the risk that researchers will overlook facts relevant to a study,既然是relevant to a study的facts,那当然是重要的. 我是这么理解的.

我和lz的问题一样，楼上层主的解释感觉不太能说服我：
1.文中说F and M contend that such risk wold still be small in most studies.不是E选项中的significant呀。
2.我觉得C选项和第一段最后一句Only in research on entirely new treatments are new and unexpected variables likely to arise意思差不多，所以选了C。是我理解有问题吗

C考了一对反义词，routinely(regularly) 和 unexpected，所以C不对。
加上C选项出处考了一个only开头倒装句。另一类倒装是否定词开头。
