Treatment for hypertension forestalls certain medical expenses by preventing strokes and heart disease. Yet any money so saved amounts to only one-fourth of the expenditures required to treat the hypertensive population. Therefore, there is no economic justification for preventive treatment for hypertension. Which of the following, if true, is most damaging to the conclusion above? (A) The many fatal strokes and heart attacks resulting from untreated hypertension cause insignificant medical expenditures but large economic losses of other sorts. (B) The cost, per patient, of preventive treatment for hypertension would remain constant even if such treatment were instituted on a large scale. (C) In matters of health care, economic considerations should ideally not be dominant. (D) Effective prevention presupposes early diagnosis, and programs to ensure early diagnosis are costly. (E) The net savings in medical resources achieved by some preventive health measures are smaller than the net losses attributable to certain other measures of this kind.
e是否可以解释为,saving比loss少,所以是无关的。请问如果有选项是说saving比loss多,那这个选项就是正确的,可以这样理解吗?
不是这样的。E讲的是不同的预防措施之间的比较;有的措施省有的措施费,但文中说整体上预防措施是省钱的;至于各个措施是什么关系,并不重要,也不是本文所涉及的。所以无关。 |
