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.

从文中第26-30行的句子可知:F和M的方法需要研究多个病人在不同条件下的状况,以及还要考虑病人的不同分类。由此可知,其对立面,即文章第21行到第23行的研究者不用考虑如此多的变量。选择一个与此相关的选项即可
A错误,与more data无关
B错误,与cost和long term无关
C正确,与解题思路接近
D错误,文章第二段的后半部分提及了subgroup,但是与此问题无关
E错误,文中未涉及average patient

    FM新方法的优点是various conditions= various variables而旧方法study与其相反,自然就是limit variables

    原文高亮部分和后面的 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.这个地方有一个转折,但是不明显,F和M的策略和大多数科学家的策略是不一样的

    这题高亮错了啊 应该高亮第一段的这句话: Only in research on entirely new treatments are new and unexpected variables likely to arise.
