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?

AMany of the patients who receive coronary bypass surgery are less than 55 years old.
BPossible benefits of coronary bypass surgery include both relief from troubling symptoms and prolongation of life.
CMost 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.
DThe 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.
EThe 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.

正确答案: E

That needs to fcous on what's the question talking about and what's the intention of the question asked by ETS.

In this question,you have to find what is the conclusion and then find an answer that weaken the conclusion,Something has nothing related to the conclusion should be elminated by yourself when you finish reading the choices at one time.
