og12 逻辑109题请教一下各位，谢谢！

109.  Springfi eld Fire Commissioner: The vast majority of false fi re alarms are prank calls made anonymously from fi re
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 fi re.
Which of the following, if true, most strongly supports the claim that the proposal, if carried out, will have the
announced effect?
(A)  The fi re department traces all alarm calls made from private telephones and records where they
came from.
(B)  Maintaining the fi re alarm boxes costs Springfi eld approximately $5 million annually.
(C)  A telephone call can provide the fi re department with more information about the nature and size of a fi re
than can an alarm placed from an alarm box.
(D)  Responding to false alarms signifi cantly reduces the fi re department’s capacity for responding to fi res.
(E)  On any given day, a signifi cant percentage of the public telephones in Springfi eld are out of service.
答案是A
