Springfield Fire Commissioner: The vast majority of false fier alarms are prank calls made anonymously from fire alarm boxes on street corners. Since virtually every one has access to a private telephone, these alarm boxes have outlived their usefulness. Therefore, we propose to remove the boxes. Removing the boxes will reduce the number of prank calls without hampering people's ability to report a fire.
Which of the following, if true, most strongly supports the claims that the proposal, if carried out, will have the announced effect?
A. The fire department traces all alarm calls made from private telephones and records where they came from.
B. Maintaining the fire alarm boxes costs Springfield approcimately $5 million annually.
C. A telephone call can provide the fire department with more information about the nature and size of a fire than can an alarm placed from an alarm box.
D. Responding to false alarms significantly reduces the fire department's capacity for responding to fires.
E. On any given day, a significant percentage of the public telephones in Springfield are out of service.
求助，谁可以把这道题分析一下，求解释。作者: maylovemay 时间: 2012-6-1 22:03
OG上的答案是A，OG的分析如下：
根据原文内容，proposal是“移走大街上的公共火警箱”，这样做的作用是：在不影响人们正常报火警能力的情况下，尽可能减少那些恶作剧的火警。再来逐个看五个选项，哪个对该结论起到了加强的作用：
A 消防部门能够追查出所有火警都是从哪里报出来的——加强结论。因为，如果能查出火警来源，那么，人们就不敢随便恶作剧地报火警，同时，由于人人都有私人电话，因此，移走箱子，并不妨碍人们正常报火警。
B 对火警箱的维护，需要花费50万刀——无关选项
C 与公共火警箱比起来，私人电话能够提供更多的火灾信息——无关选项。因此，提供信息的多少，跟减少恶作剧没有关系。
D 应对假火警，削弱了消防部门的灭火能力——这个跟“减少恶作剧”与“不妨碍人们正常报火警的能力”没有关系，属于无关选项。
E 在假定的任何一天，总有很大比例的公共火警箱不好用——明显的无关选项。作者: wanghongl 时间: 2012-6-2 05:59
