og13 逻辑 111 有点矛盾的题干和解释……求解答！

楼主，C一直在强调私人电话和公共火警电话的报火警的特点，是无关选项。
A， 救火部门有能力追踪所有的火警电话，与conclusion的不影响救灾能力是方向一致的，因此A对

C选项取非后没有削弱，所以不选。

题目里面已经说了everyone has...那么就应该不存在解释里的如果某一个人只能找到电话亭而没有手机报警的情况了，所以既然每一个人都能用手机报警，并且也A选项也说明了能定位手机的位置，那么把电话亭撤了就不会影响大家报火警的能力了。

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.

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

为什么不选c的原因：
This option is incorrect. It is beyond the scope of the argument. As per this choice, a fire reported from a telephone call may be more informative than a fire reported from an alarm box.  However, the purpose behind the author’s proposal is to reduce the magnitude of trick calls without reducing people’s ability to report fires. The author is not concerned with the quality of the alarm calls made.Hence, this answer choice does not support the author’s proposal and is, therefore, not the correct answer choice.

断了的弦

题干的目的是 reduce the number of prank calls without hampering people's ability to report a fire.
a既能追踪报警人防止恶作剧又能响应报警，完全符合

个人观点~
我认为本题的关键在于私人电话和报警箱的区别。原文其实默认了私人电话不会产生恶作剧电话且它的报警能力等效。
A项同时加强了题干的两点有效性。1报警箱匿名，但私人电话可以定位，所以减少了恶作剧电话。2报警箱是固定在街角的，但私人电话不是。但通过对私人电话的追踪，可以使私人电话have ability to report a fire
而C项，勉强加强了报警能力，但并没有达到减少恶作剧电话的目的。
