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,可是我觉得proposal的重点是解决了假报警的问题,因此支持这个proposal也应该从这方面寻找论据,我选A,因为用box的时候**没有办法监控,而用私人电话就可以监控的到,所以人们不会用私人电话假报警.这样理解为什么不对呢?谢谢指点哦~~
