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.
