Question ID:PT61 S2 Q20 Passage:When people show signs of having a heart attack an electrocardiograph (EKG) is often used to diagnose their condition. In a study, a computer program for EKG diagnosis of heart attacks was pitted against a very experienced, highly skilled cardiologist. The program correctly diagnosed a significantly higher proportion of the cases that were later confirmed to be heart attacks than did the cardiologist. Interpreting EKG data, therefore, should be left to computer programs. Stem:Which one of the following, if true, most weakens the argument? Correct Answer Choice:CChoice A:Experts agreed that the cardiologist made few obvious mistakes in reading and interpreting the EKG data. Choice B:The practice of medicine is as much an art as a science, and computer programs are not easily adapted to making subjective judgments. Choice C:The cardiologist correctly diagnosed a significantly higher proportion of the cases in which no heart attack occurred than did the computer program. Choice D:In a considerable percentage of cases, EKG data alone are insufficient to enable either computer programs or cardiologists to make accurate diagnoses. Choice E:The cardiologist in the study was unrepresentative of cardiologists in general with respect to skill and experience.
