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.

邏輯鏈：老人摔倒治療要花11000，防止老人摔倒的治療要花12500—》這個防止治療不可行

問削弱

A?談的是防止治療持續(xù)的時間和治療效果的關(guān)系

B?談的是獨居群居和摔倒發(fā)生率的關(guān)系

C?摔倒后長期后續(xù)治療的費用沒算在這11000里

D?談的是防止治療的好處擎浴，可以避免過度用藥

E?談的是防止治療里面不同治療手段和各自發(fā)生的費用的關(guān)系

邏輯鏈聚焦是費用差異導(dǎo)致治療不可行查蓉，要削弱的話，也要聚焦在費用上副签，這樣就只剩C?E在談費用了，C談的是11000這個費用有可能更高基矮，更高的話就會高于12500淆储，那么就逆轉(zhuǎn)了原文推理依據(jù)里面的費用差異了，可以削弱結(jié)論家浇。E選項談的是12500內(nèi)部費用分配的問題本砰，和總額無關(guān)，無法削弱原文推理钢悲。

答案：C
