Q22.

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 tele-

phones 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 informa-

tion 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 depart-

ment’s capacity for responding to fires.

E.      On any given day, a significant percentage of the public telephones

in Springfield are out of service.
