[求助]GWD-8-Q6

       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-Q6 :

The passage is primarily concerned with

A.      identifying two practices in medical research that may affect the accuracy of clinical trials

B.       describing aspects of medical research that tend to drive up costs

C.      evaluating an analysis of certain shortcomings of current medical research practices

D.      describing proposed changes to the ways in which clinical trials are conducted

E.       explaining how medical researchers have traditionally conducted clinical trials and how such trials are likely to change

答案是D, C为什么不对啊？原文说thereby escalating costs of data collection, storage, and analysis难道不是指出shortcomings么， 请牛牛指教啊~~

Frazier and Mosteller propose not only that researchers limit data collection on individual patients but also that researchers enroll more patients in clinical trial...说明了F和M有两项建议。从not only和but also看，上一段应该是一种建议，第二段应该是另一种建议。因此，整篇文章都在说两种建议分别是什么。escalating costs of data collection, storage, and analysis只是形成第一种建议的原因之一。

请支持把字号调大的建议。这么长文字，这么小的字号，头晕阿！谢谢啦！

支持楼上的～

第一句话就可看出：“Frazier and Mosteller assert that medical research could
be improved by a move
toward larger, simpler
clinical trials of medical treatments.”

意在"propose changes"然后第一段分讲simpler，第二段分讲larger。

第一段中讲出flaw只是想强调simplification的重要性
