109．Springfield Fire Commissioner: The vast majority offalse fire alarms are prank calls made anonymouslyfrom fire alarm boxes on street corners. Since virtuallyeveryone has access to a private telephone, thesealarm boxes have outlived their usefulness. Therefore,we propose to remove the boxes. Removing the boxeswill reduce the number of prank calls withouthampering 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.

(0A 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..没有问题·
只是不知道为什么OG说E选项是weakens support for (2):doing so will not hamper people's ability to report fires
自己觉得public telephones在这儿是无关选项吖··又不懂OG了···

谁能解释一下D为啥错了呢？

顶~~问题同LZ

我是这么想的

D也可以算是一种weaken；一种弱得weaken， On any given day, a significant percentage of the public telephones in Springfield are out of service.


能够打报警电话的：1， alarm box, 2. private telephone, 3. public telephones(stimulus中没有提到）

如果public telephones电话好的话也就没有问题了，但是如果经常坏，会对报火警不利，因为有可能会有人没有私人电话

通常这个选项我也会认为是无关，直接排掉

D这种选项我认为是对background information的描述，和conclusion内的关系无关

为什么这个是背景信息呢？
这么看吧

conclusion: Removing the boxeswill reduce the number of prank calls without hampering people's ability to report a fire
why we must reduce the number of prank calls ?

because; The vast majority offalse fire alarms are prank calls made anonymously from fire alarm boxes on street corners

why we can't have false alarms

because : Responding to false alarms significantly reduces the fire department's capacity for responding

所以D是介绍描述premise成立的原因，操作的原因和conclusion没有影响关系

既然每家都有phone了，当然不会妨碍人们报警。但是有A的存在的确能防止错打或者恶意报警的可能性。问题关键是防止恶意报警。

谢谢3楼的回复·但做CR时就是要把自己当白痴，不要用任何的背景知识·
既然文中根本就没有提供public telephone, 还是当无关的好·
OG有时候有点自相矛盾的感觉··

C discusses the ability to give specific information about a fire. The ability to provide SPECIFICS is not the same as the ability to REPORT a fire -- the only issue at hand here. The ability to REPORT a fire could still be hampered if private phones are not able to reach the fire department as readily as alarm boxes.
Even more troubling, C says only that a telephone call CAN provide more information; it does not say that telephone calls actually DO provide more information.

看了半天想通了：

原文中的结论是“移除报警器降低...不会影响...”，并非“提议移除报警器”，（问题也明确说是针对前者结论的问的）

D选项支持了“应该移除报警器”，而没有直接支持结论。OG针对D的解释并不好

D项解释了题目背景，即警局为什么要制止prank call ，而不是加强结论（减少公共boxes从而在不影响人们报警的情况下有效减少prank call）；A项确实起到了补充结论GAP的作用，防止人们利用个人电话也打prank call（og解释中言外之意是A支持了（1）），补充即是加强，A正解
