问题 Heart specialists at Pap-worth Hospital, Cambridge, have urged that the heart trans plant program be stopped.
The hospital’s three consultant cardiologists(心血管专家)have written to Mr. Terence, the surgeon in charge of the transplant team, for the purpose of disconnecting themselves from his work and have sent a copy to Department of Health and Social Security. No cardiologist now takes part in the program, which is run by the hospital’s surgeons(外科医生).
Dr. David Wainwright Evans, one of the three specialists, hopes that when the charity(慈善)money for the program runs out in January, the Government will not take over the funding.
So far the program has cost ￡ 1. 5 million and has saved the lives of only 40 out of the 78 transplant patients. Pap-worth and Hare-field Hospital, West London, have each transplanted 39 patients;22 have survived at Pap worth and 18 at Hare-field. The longest-surviving Pap-worth patient, Mr. Keith Castle, recently celebrated the third anniversary of his transplant operation.
Mr. Christopher Robbins, director of the Coronary(冠心病)Prevention Croup battling to reduce the 150,000 deaths a year from coronary heart disease, said that heart transplants would never benefit more than a tiny minority of heart patients, yet thousands could be saved by preventive measures.
In the United States the number of premature deaths(英年早逝)from heart disease has been reduced by a quarter since 1963 through changes in life-style. Evidence suggests that similar results could be obtained in Britain. [br] According to the passage, the success rate for heart transplants is about______.

选项 A、45%
B、50%
C、0.55
D、0.6

答案 B
