以下是引用michaellu97在2006-12-29 10:12:00的发言：
此题背后还有一个意思，这些 alarm box 是可以被追踪的，如果不能被追踪的话，fire dept 就不知道到哪里去灭火了。

要支持 “without hampering people's ability to report a fire”，就要说明用 private phone 可以达到 alarm box 一样的效果，这就说明 A 是正确的。

C 和 D 都是说明用 private phone 带来的好处，而不是解释 "without hampering people's ability to report a fire"

总结一下，原文有两个目的

1。reduce the number of prank calls

2。without hampering people’s ability to report a fire.

争论是，support应该加强第一个目的还是第二个目的

答案A和C：

A  made from private telephones and records where they came from.
（alarm box本身是可以被追踪location的，这算是个背景知识吧，同意michaellu说的）私人电话可以被追踪，达到和alarm box定位一样的作用（哪里发生了火灾）（然而私人电话不会有prank call）
这个答案满足了原文结论的两个目的，减少prank call，也达到alarm box一样的定位位效果（如果没有定位功能就会hamper people's ability to report a fire)

C  是说这样可以提供more information about the nature and size of a fire。 提供火灾的大小和性质信息其实和本题所说的目的：prank call和hamper people's ability to report a fire无关。因为原文需要support的是私人电话没有牵制人们的能力，而不是增强了其他什么能力，比如报告火灾的大小和性质

希望nn出来指正

Friskies

选C

A是无关选项。理由：题干说the vast majority of false fire alarms
        are prank calls made anonymously from fire alarm boxes on street
        corners.是说假警报绝大部分都是从fire alarm box出来的，注意：人家可没说私人电话有可能报假警哦。所以，蓝色部分就不在我们考虑范围了Removing the boxes will reduce the
                number of prank calls
                without hampering people’s ability to report a fire

C说电话比火警箱的好处则可以加强绿色部分

guozili

此题选D

题目的论点是：Removing the boxes will reduce the number of prank calls without hampering people’s ability to report a fire.

A，C那个跟report a fire的ability有关系？A,C说的都是消防系统的ability强，跟老百姓打电话报警的ability没关系

D说明取消boxes 可以增加老百姓report a fire的ability（因为box产生的乱打电话导致接待火警的人忙于应付，反而正常的报警电话打不进来，阻碍了老百姓report a fire的ability），刚好加强。

我觉得A无关吧。可以trace又如何呢？trace的结果在题目里根本没有表示，不能推测的。常识以为trace了就会有威慑，但实际是否有威慑，有多大威慑，题目没说，所以不能推测。我觉得C好一些，既然phone可以更清楚的描述火情，那么就是说phone是更好的手段，加强了“取代alarm”这个结论。

选择A应该是go too far了。

23楼讲的很清楚了。GWD也告诫我们，不要用常识去推理，就算能知道 traces all alarm calls made from private telephones and records where they came from这些信息又如何，文章没有说因此可以减少prank call,更何况大多数prank call是由于fire box而来，A更加是无关信息。

C

大家仔细读一下加强的部分:

 Removing the boxes will reduce the
        number of prank calls without hampering people’s ability to report a fire.

再注意一下黄色区域里people’s ability to report a fire.

只有C加强的是people’s ability to report

这样看来A.D都是无关

I believe that you have to understand how the alarm box works to answer this question. Below is from Wikipedia:

A fire alarm box is an outdoor device used for notifying a fire department of a fire. Early boxes used the telegraph system and were the main method of calling the fire department to a neighborhood in the days before people had telephones. When the box is triggered, a spring-loaded wheel spins and taps out a signal onto the telegraph wire, indicating the box number. The receiver at a fire station then can match the number to the neighborhood. The boxes are still in service in many places, though many towns and cities are now questioning whether they are worth the cost to maintain. 

The claim is "Removing the boxes will reduce the number of prank calls
   without hampering people’s ability to report a fire." 

Without hampering people's ability to report a fire is a given condition since "virtually everyone has access to a private telephone". The argument didn't mention anything about improving or enhancing the ability to report just "not hampering". 

The answer has to support "reduce the number of prank calls". The problem with the alarm boxes on street corners is that the fire department can not identify the caller as it's anonymous. Making prank calls to fire department is an unlawful act. When people know that the fire department can trace a prank call, obviously, fewer people will risk it. Hence, fire department can expect fewer prank calls.

A is correct.
