请问你是看不懂呢，还是不知道如何排除其他选项？我大概按照我的理解来给你解释一下
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.
关注结论，题目问削弱，就是找一个选项指出有economic justification
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. 中风和心脏病源于不治疗的hypertension，虽然医疗花费不高，但是有其他巨大的经济损失。【重点把握：insignificant expenditure/ large economic losses】
(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.
105.
If the results of untreated hypertension cause large economic losses, as choice A claims, then the treatment of hypertension may well be economically justifiable. Therefore choice A is most damaging to the conclusion and is the best answer.
Choices B and D tend to support the conclusion; choice B says that making preventive treatment widespread would not introduce economies of scale, and choice D identifies one aspect of prevention that is both costly and essential. Choice C undermines a different conclusion-that society should not support treatment for hypertension-but does not damage the conclusion actually drawn. The fact that different preventive health measures have different economic consequences (choice D) gives no specific information about treatment for hypertension, and so cannot affect the conclusion drawn.
