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,我选D,不否认C也是可以undermine的,可是我觉得D更好。

The prairie vole, a small North American grassland rodent, breeds year-round, and a group of voles living together consists primarily of an extended family, often including two or more litters. Voles commonly live in large groups from late autumn through winter; from spring through early autumn, however, most voles live in far smaller groups. The seasonal variation in group size can probably be explained by a seasonal variation in mortality among young voles.
Which of the following, if true, provides the strongest support for the explanation offered?
(A) It is in the spring and early summer that prairie vole communities generally contain the highest proportion of young voles. (B) Prairie vole populations vary dramatically in size from year to year. (C) The prairie vole subsists primarily on broad-leaved plants that are abundant only in spring. (D) Winters in the prairie voles' habitat are often harsh, with temperatures that drop well below freezing. (E) Snakes, a major predator of young prairie voles, are active only from spring through early autumn. 答案为E,我选D,而且百思不得其解,E怎么就support了? |
