GWD8-Q4

viviansecret

 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.

答案：E。这个E我是明白的。但是不明白为什么B选项不正确。因为在全文的最后部分有这样的一段话：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.这个难道没有暗示B是正确的吗？请nn多多指教哦：）

这道题我还觉得C)对呢，E)里面的significant并没有在文章中有提到过。

C不对吧，routinely是说例行公事的，应该可以理解成有new treatments就会有new virables吧，但文中只是说

Only in research on entirely new treatments are new and unexpected variables likely to arise.可能

弱问：D为什么不对呀~~~

Although limiting information collection BLABLA
FM 提倡的简化收集，这样会overlook facts. 不是accurate

这道题虽然C中的routine用得不好，但是E怎么会是答案呢？
原文：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.
说的是虽然减少采集的信息会增加忽略一些参数的风险，但是FM认为这些不可避免的风险是很小的
E说的是一定会有重要的参数被忽略，显然和原文相悖啊！
求大神指导

原文：Although limiting information collection ...

要看到 such risk, never entirely eliminable from research 意味着这种风险是不可避免的。 那个will still be small 指的是risk 本身， 不是risk不可避免的程度。
E选项里说 cannot freed 也指的是不可避免 与原文意思相符。
