[求助]一道GWD CR

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.

答案是C 我选了D。

The fire commissioner suggests removing the boxes will not hamper people's ability to report a fire. He implies that people can use telephone instead.

C: If there is some task people can do with fire boxes but cannot do with a telephone, then people's ability to report a fire is said to be hampered. In order this not to happen, telephone should be at least as capable as fire boxes of reporting fires.

D indicates how the fire department's work is affected after removing the boxes. It has nothing to do with people's ability to report a fire. This is not relavent to the fire commissioner's conclusion.
