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.

请教各位的是：

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.

答案是E，但是我认为significant有夸大之嫌，毕竟原文描述是：

Frazier and Mosteller contend that such risk, never entirely eliminable from research, would still be small in most studies.

相对来说，我觉得B更贴近一些。

请牛牛们指教

我选了C。。。

同问，觉得E选项significant variables文中并没有提到，请牛牛出来讲讲吧？

C)对应的是这句话：Only in research on entirely new treatments are new and unexpected variables likely to arise.
E)对应的是这句话：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.
我也倾向于C)，毕竟如VivienZheng所说文中并没有提到significant的variables会被overlook。对C)唯一的疑问就是routinely reveals和arise看起来并不是同一个意思。

不是NN

我一开始也选c 后来仔细看知道c的问题是原文中是讲unexpected varibales 所以c 中的routinely reveals肯定就错了

至于楼上关于significant的异议原文中是说risk是small 但e中的significant是指variable　可能这两个有差吧

请继续讨论。。。

我也有这个问题，先选C，后来仔细比对后，发现，C/E肯定错。坚持认为该选B，请NN来解答一下

作者: xiaoxiangxixi 时间: 2010-6-30 22:06

我开始选C

后来routinely和significant比较，还是E比较好一点。

肯定不是B。B是虚拟的

原文中：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.

B. It tends to benefit certain subgroups of patients disproportionately

所以我觉得B不对
