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.

答案为C

即使new therapeutic program因为没有将医药费算入而有可能划算，但是这个选项也不能正面解释它的花费一定比old program划算啊？？

正好做到这道题，说点看法：d错在overmedication ，这是文中并未提到的信息

顶上，同问

老年人摔跤治疗要花费$11,000，有一个项目可以减少摔跤机会，但是要花费$12,500，所以这个项目并不好

文章推理：因为项目成本高，所以不好

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.

比较参加项目时间长短，和推理无关，属于搭错车，无关比较

(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.

把不同地方的老年人对比，和成本无关，属于无关比较

(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.

正确说到了关键点cost，之前的$11,000中并不包含治疗疼痛的医疗费，如果加上可能成本会更高超过参加项目。他因反对结论

(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.

只是说过度的medication可以导致不协调造成更多的摔跤，并且这个项目关注medication以外的东西。属于模凌两可，因为不知道medication以外的东西是不是就是好的。这个选项具有迷惑性

 (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.

只是说明了新项目费用高的来源，没有进行比较，说东道西

解释得真详细！！！
