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. 还是同意D。 D说明取消boxes 可以增加老百姓report a fire的ability(因为box产生的乱打电话导致接待火警的人忙于应付,反而正常的报警电话打不进来,阻碍了老百姓report a fire的ability),刚好加强。 C 说的是 telephone call 的物理属性,比较的是两种电话。但如果你在家里用telephone call报警给消防局,如果街边捣乱的电话很多一直占着消防局的线,你的ability 当然被hamper了!注意题目里问的是 without hampering people’s ability to report a fire. 而不是在讨论两种电话的优势、劣势! |
