由于自己也有类似的疑问，所以仔细分析了一下，以下是我的理解。
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
TYPE: STRENGTHEN
LOGIC:
boxes-unknown calls-false fire alarms→（1）remove boxes -reduce unknown calls ∵private phones-(known calls)(assumption)-correct fire alarms→ ∴（2）without hampering the fire report
SOLUTION: for an option to be correct it must support either (1) or (2) or both
ANALYSIS:
(A) The fire department traces all alarm calls made from private telephones and records where they came from.
if private calls are traced & recorded where they come from→where the fire is →no need for boxes & no negative effect on fire report. Correct.
(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.
private calls provide more info about fire (what)→cannot indicate where the fire is→only better when there is a fire alarm
so 'There is still the possibility that the only person aware that a fire has started is near an alarm box (where) but lacks access to a telephone (info about the nature and size of the fire).'
∴irrelevant
2楼的理解也挺好记的，我是尝试从OG的角度去理解。作者: meiyw 时间: 2016-10-13 15:08
简单来说，就是C选项不能说，人们不会拿手机打prankcalls，所以起不到效果。A就能威慑到群众，查清谁打的谁还敢打。
