谢谢lawyer的解释，非常的清楚，真是牛。

对于A项，做题时，自己觉得既然大多数病人做手术都是在55岁下，所以能活到65岁，这就说明了病人都受益了。但该题削弱的重点是医生的出发点是不道德的，和客观病人受益情况是无关的，因此A是无关。

65岁以上的人接受心脏搭桥手术，其中只有75%的人能够得到改善；剩下的1/4 人，都是医生昧着良心送入手术室的。

错选的A明显无关；D说病人不知道对自己有没有害；E指医生不知道对病人有没有好处，也就是assumption医生知道对病人没好处，却知而为之。

还是想不明白这T啊！5555

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.   Possible 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.

结论是医生看practise skills 和FEE ，E 怎么WEAKEN啊！E说手术前，觉得无关啊！当时选的时候排除就觉得DE 是答案，然后就选了D

For one in four such patients,说明，Conculsion是针对“医生可以分得清哪些是1/4，哪些是3/4的”所以削弱的话，就是说这些人根本没法区分。

这个是我的理解。

D是说了都被告示手术的危险性，但是这个是无关的，如果被告之不会受益，这才是weaken。就算告知有危险，医生还是有可能是为了practice，如果他能在手术之前就看出来某个病人不会受益的话。

大家觉得这个but 有没有问题啊,我觉得应该是and 吧, 原文是but 搞得我看不懂是什么意思, 如果换成了and 的话意思就明白了,答案就好选了

同意。D说医生告诉病人手术的危险性，但并没有告诉病人：“老兄，你的病治不好的，我给你动手术的目的是为了practice，顺便赚点fee。”
