Springfield FireCommissioner: the vast majority of false fire alarms are prank calls madeanonymously from fire alarm boxes on street corners. Sincevirtually everyone has access to a private telephone, these alarm boxeshave outlived their usefulness. Therefore, we propose to remove theboxes. Removing the boxes will reduce the number of prank callswithout hampering people’s ability to report a fire.
Which of the following, if true, most strongly supports the claim that the proposal, if carriedout, 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 afire 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. Onany given day, a significant percentage of the public telephones in Springfield are out of service.
我觉得A和C都对。。 这里不选box是因为box 没用。而且可以被private phone 代替。。 要support 的话 应该说Box 到底有多无用 或者说private phone 为何可以取代。。。 box 的唯一优点就是因为能确定location吗？？ 所以之所以phone 能取代就是因为也可以track location??? 那C说的无关？？ 。。。我好像把自己说明白了- - 。。。。 |
