求教 OG12 109

109. Springfield Fire Commissioner: The vast majority of false fire alarms are prank calls made anonymously from fire alarm boxes on street corners. Since virtually everyone 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 claim 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 approximately $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.


答案是A，我选的是E。
OG的E选项解释：This actually weakens support for(2)[doing so will not hamper people's ability to report fires], by enhancing the possibility that the only person aware that a fire has started is near an alarm box but lacks access to a working telephone.
我不懂的是：很多公共电话不能用，那么即使有火警人们也不能用公共电话报警啊，那么取消公共电话对人们报警的能力没有影响啊，为什么不选E？

楼主，我觉得你没有很好的理解题干，题干说的是谎报火警大多数是fire

alarm boxes造成的，就是街角那种按一下就响的手动报火警的装置。题目然

后说因为几乎每个人都可以用电话报警（可能通过手机，座机或公用电话）。

我们假设一个人没有手机，在街上，需要报火警，但是他可能无法使用公用电

话，因为大多数公用电话不能用，那么这时他可以按box，如果box被移除以后，

他就无法报警了，这难道不是hamper了报警的能力吗？

噢，我把公共电话和报警盒子当成同一种报警装置了。谢谢你！
