标题: 问一道逻辑小题~ [打印本页] 作者: yaoxiayi 时间: 2010-4-21 16:31 标题: 问一道逻辑小题~ Of patients over 65 years old who survived coronary bypass surgery—a procedure widely prescribed for people with heart disease—only 75 percent benefited from the surgery. Thus it appears that for one in four such patients, the doctors who advised them to undergo this surgery, with its attendant risks and expense, were more interested in an opportunity to practice their skills and in their fee than in helping the patient.
Which of the following, if true, most seriously undermines the argument?
A. Many of the patients who receive coronary bypass surgery are less than 55 years old. B. ossible benefits of coronary bypass surgery include both relief from troubling symptoms and prolongation of life. C. Most of the patients in the survey decided to undergo coronary bypass surgery because they were advised that the surgery would reduce their risk of future heart attacks. D. The patients over 65 years old who did not benefit from the coronary bypass surgery were as fully informed as those who did benefit from the surgery as to the risks of the surgery prior to undergoing it. E. The patients who underwent coronary bypass surgery but who did not benefit from it were medically indistinguishable, prior to their surgery, from the patients who did benefit.
答案是E，可是我觉得D还有A都可以嘛~~作者: ruimiss 时间: 2010-4-21 19:39
在进手术室之前，受益于该手术的病人与结果失败的病人没有差别。就是说医生分辨不出哪个会手术失败，那么就不能说医生对手术失败的病人是不负责任或者说是more interested in an opportunity to practice their skills and in their fee than in helping the patient，毕竟医生也分辨不出谁会失败。所以不存在对谁更不公平，其实都是公平的 。
