标题: 逻辑求解··
Economist: On average, the emergency treatment for an elderly person for injuries resulting from a fall costs $11,000. A new therapeutic program can significantly reduce an elderly person's chances of falling. Though obviously desirable for many reasons, this treatment program will cost $12,500 and thus cannot be justified.

Which of the following, if true, most seriously undermines the conclusion of the argument?

(A) Among elderly people who had followed the program for only a few months, the number of serious falls reported was higher than it was for people who had followed the program for its recommended minimum length of one year.
(B) Falls resulting in serious injuries are less common among elderly people living in nursing homes than they are among elderly people who live alone at home.
(C) A frequent result of injuries sustained in falls is long-term pain, medication for which is not counted among the average per-person costs of emergency treatment for elderly people's injuries from such falls.
(D) The new therapeutic program focuses on therapies other than medication, since overmedication can cause disorientation and hence increase the likelihood that an elderly person will have a serious fall.
(E) A significant portion of the cost of the new therapeutic program is represented by regular visits by health care professionals, the costs of which tend to increase more rapidly than do those of other elements of the program.

我个人理解的argument应该是the new therapeutic program can significantly reduce an elderly person's chances of falling，所以我选了A，但是为什么答案会选C啊？求教··

注意thus，这里的结论应该是this treatment program cannot be justified.
假设是因为新的这个program会cost $12500，成本比原来的emergency treatment还高。
A只是说明了这个新program的效果，但不能说明这个新program不好，A有点support了，而不是weaken。
C说了之前的旧program的成本之所以低是因为它没有包括medication的费用，这样就weaken了假设。

想问版主，D为什么错呢？D提出了他因;新项目有另一个好处。

D的意思是过量治疗会带来更多的危害，但是并不是所有的治疗都是过量治疗，引入的新观点其实并没有解释清楚
