10. Traverton'scity council wants to minimize the city's average yearly expenditures on itstraffic signal lights and so is considering replacing the incandescent bulbscurrently in use with arrays of light-emitting diodes (LEDs) as the incandescentbulbs burn out. Compared to incandescent bulbs, LED arrays consume significantlyless energy and cost no more to purchase. Moreover, the costs associated with the conversion of existing fixtures so as to accept LED arrays would be minimal.

Which of the following would it be most useful to know in determining whether switching to LED arrays would be likely to help minimize Traverton's yearly maintenance costs?

(A) Whether the expected service life of LED arrays is at least as long as that of the currently used incandescent bulbs

(B) Whether any cities have switched from incandescent lights in their traffic signals to lighting elements other than LED arrays

(C) Whether the company from which Traverton currently buys incandescent bulbs for traffic signals also sells LED arrays

(D) Whether Traverton's city council plans to increase the number of traffic signal lights in Traverton

(E) Whether thecrews that currently replace incandescent bulbs in Traverton's traffic signalsknow how to convert the existing fixtures so as to accept LED arrays

原文：T市政厅希望最小化其在交通信号灯的平均年度开支，所以计划用LED灯来替代目前的白炽灯(因为其容易烧坏)。跟白炽灯比较，LED耗电更少并且不贵。并且改变目前固定装置来用LED的成本也比较低。问用LED是否可以降低一年的维护开支。

A选项，白炽灯的预期使用寿命是否和白炽灯一样长，寿命和维护开支有一定关系;

B选项，是否有城市把白炽灯改变成了lighting elements，而不是LED，无关;

C选项，卖白炽灯的公司是否卖LED，无关;

D选项，市政厅是否计划增加信号灯数量;

E选项，目前替换白炽灯的工作人员是否知道如何改变目前装置来接受LED等，和开支无关。
