文章：
| Line | 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 | |
| (5) | 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 | |
| (10) | 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. | |
| (15) | 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 | |
| (20) | 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 | |
| (25) | 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 | |
| (30) | 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. |
题目：
Which of the following can be inferred from the passage about a study of the category of patients referred to in lines 20–22 ?
选项:
A、Its findings might have limited applicability.
B、It would be prohibitively expensive in its attempt to create ideal conditions.
C、It would be the best way to sample the total population of potential patients.
D、It would allow researchers to limit information collection without increasing the risk that important variables could be overlooked.
E、Its findings would be more accurate if it concerned treatments for a progressive disease than if it concerned treatments for a nonprogressive disease.
答案:
A

提问：
这道题我在A和D之间犹豫，最后选的D。读了一遍原文，好像隐约记得里面提到information和risk的事情，是D选项本身不对，还是说不能回答问题？
