标题: OG17 CR656题~跪求解答啊
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.

OA是A，我当时觉得A、C都对，但是OG对于C的解释是：不能排除以下可能，如果一个人被困在了一个没有人也没有手机的地方，这时发生了火灾就没办法了
我觉得把这种情况应用到A也没办法啊，所以为什么A对呢，这里附上OG的解答
Situation ：It is proposed that fire alarm boxes on street corners be removed. Doing so will
reduce the number of prank calls without hampering people’s ability to report fires. Most
false alarms are prank calls made from these boxes. They have outlived their usefulness,
as most people now have private telephones.
Reasoning ：Which option most strongly supports the claim that removing the alarm
boxes will reduce the number of prank calls without hampering people’s ability to report
a fire? The argument already provides some evidence that (1) removing the boxes will
reduce prank calls—because that is where most such call are now made from—and that (2)
doing so will not hamper people’s ability to report fires—virtually everyone already has a
private telephone from which they could report a fire. So for an option to be correct it
must support either (1) or (2) or both, and provide more such support than the other
options. If prank calls from private telephones are traced back to their origin, that should
deter people from making such calls.
A. Correct. This option provides the most support for the claim.
B. This may provide a reason for supporting the proposal, but it provides no support for
either (1) or (2).
C. This indicates that it is better to receive fire calls from telephones than from alarm
boxes—other things being equal—but that supports neither (1) nor (2). There is still
the possibility that the only person aware that a fire has started is near an alarm box
but lacks access to a telephone.
D. This merely indicates that it would be good if the proposal had the intended effects.
E. This actually weakens support for (2), 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.
The correct answer is A.

c选项说的是用手机报火警的好处但是它没说出为什么撤掉所有固定电话是不会影响报警数的 oa举得例子的意思是说有可能有些人在box周围但手机坏了那么box报火警是有用的撤掉box就让这种情况下的人无法报警了
虽然在a选项里这种情况也可能存在但你可以这样想 a表明了手机可以胜任box的角色换句话说就是可以替代box 但c只是对比了手机的好处没有表明它可以代替box 有好处不代表可替代因为box可能也有好处

非常感谢解答~ 在下比较愚钝，还是有个问题想继续请教
我可以看出C是在阐述手机的好处，但是没办法看出A是在讲手机可以替代box，我认为A也在讲手机的好处？

我又仔细思考了一下，A是说手机可以定位，box之前在固定的地方所以也有定位的优点，所以这样看来手机是可以替代box定位的功能的？这样理解对嘛，还是您有更好的见解？

对的我就是这个意思可以理解为原本box的好处有可以定位这一点现在a说了手机也可以定位那么就符合题目所说即使撤了box也不会影响报警了

结论是个双重目的，题干中premise在解释第一个目的与手段的关联，题目在于填补第二个目的与手段的gap

A）正是填补了这个gap
C）是否more info.与这个gap（即hampering people’s ability to report a fire）无关
D）加强的是第一个目的与手段的关联——无关

A） ...

Mark一下！谢谢！我终于想明白了。
顺便问一下，你的这个“填补gap”思路是哪家的呀？感觉很有用！

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.

E.On any given day, a significant percentage of the public telephones in Springfield are out of service.

1. 找出argument & line of argument
每人都有私人电话，取消防火警报箱可以减少假警报，也不会影响火灾报警

2. 分析逻辑
两个逻辑事物
A 私人电话报警
B 减少假警报，也不会影响火灾报警

想像一下，如果和朋友争辩
找茬 - 私人电话报警，也不一定会减少假警报啊。如果私人电话无法跟踪，还是可以假。其它找茬逻辑上也可以说私人电话不方便报警。好比加入坏天气时私人电话容易停之类。

3. 答案
A 增强。把找茬漏洞之一补上
B easy 无关。火警报箱费多少钱，对A->B无关。
C Tricky 无关。私人电话可以告诉更多细节，但是还是和A->B无关。私人电话可以告诉更多细节，但不代表它一定要这么做，而且假火警也可以说很多假的细节。如果私人电话无法跟踪，还是可以报假火警开玩笑。
D easy 无关。假火警不好。但对A->B无关
E really easy 无关。公用电话失灵不影响私人电话。

关键是找到A->B，然后集中逻辑思维在A->B来考核答案
