22. GWD25-Q22.

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
  five million dollars 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C

题目说大多少恶作剧电话是用街边的alarm boxes打的，但是现在既然大家都有了私人电话，这些alarm boxes就可以搬走了。

如果题目没有最后一句话"Removing the boxes will reduce the
   number of prank calls without hampering people’s ability to report a fire."，选C毫无疑问。

但是有了这句话后，题目的意思就是去掉alarm boxes可以减少恶作剧电话，同时不妨碍真实的报灾电话。

这样的话,我觉得A选项：救火中心对私人电话都能记录来源，意思就是私人电话无法匿名搞恶作剧，从而加强。

请指正！

注意细读，

1大部分错误的火警都是来自于alarm boxes的匿名恶作剧电话，2因为每个人都有私人电

话，alarm boxes 是没有必要的，3所以移除alarm boxes会在降低恶作剧电话的同时没有

阻碍报警的能力（without hampering people’s ability to report a fire）

首先，因为恶作剧电话大多数来自alarm boxes，显然Removing the boxes will reduce

the  number of prank calls是成立的 ，文章结论的重点在于没有阻碍报警能力，那么D

选项说明了这点，补充了Removing the boxes -not hamper people’s ability to

report a fire中间的gap，所以是答案。

如果硬是强调要去支持Removing the boxes -reduce the  number of prank calls这条

逻辑链，这里会出现一个gap，即那些打恶作剧电话的人不会“全部”（如果有一部分人

转一样会是reduce）转用私人电话上打，A似乎为填补这个gap创造了条件，有支持的作用

。但是support一般都是直接填补gap，只是创造了一个需要去发挥个人想象的条件，显然

支持作用不如D
