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.

从文中信息可知,Patients’ ages may also affect a treatment’s efficacy,证明前面谈到了影响临床试验效力的一个因素,而这是另外一个因素。这属于F和M提出的扩大病人样本的进一步说明。正确答案要与此相关
A错误,most原文并没有提及
B错误,与“质疑执行F和M建议的执行力”无关
C错误,Patients’ ages...与progressive disease所在的句子是并列关系
D正确,谈及了作者在第二段的主要观点
E错误,文中未谈及“招募大量的病人参与临床试验本身的问题”

    目的题,C选项是细节例子小目的,而D是段落大目的。细节例子是为段落主旨服务的,所以选D
