(30658-!-item-!-188;#058&005491) (GWD 7-Q17) Ofpatients over 65 years old who survived coronary bypass surgery—a procedurewidely prescribed for people with heart disease—only 75 percent benefited fromthe surgery. Thus it appears that forone in four such patients, the doctors who advised them to undergo thissurgery, with its attendant risks and expense, were more interested in anopportunity to practice their skills and in their fee than in helping thepatient.Whichof the following, if true, most seriously undermines the argument? A. Manyof the patients who receive coronary bypass surgery are less than 55 years old. B.Possible benefits of coronary bypass surgery include both relief from troublingsymptoms and prolongation of life. C.Most of the patients in the survey decided to undergo coronary bypass surgerybecause they were advised that the surgery would reduce their risk of futureheart attacks. D.The patients over 65 years old who did not benefit from the coronary bypasssurgery were as fully informed as those who did benefit from the surgery as tothe risks of the surgery prior to undergoing it. E. The patients who underwent coronarybypass surgery but who did not benefit from it were medicallyindistinguishable, prior to their surgery, from the patients who did benefit. 应该选E,我选的是A,不明白呀!!! |
