题目：
Highway Official: When resurfacing our concrete bridges, we should use electrically conductive concrete (ECC) rather than standard concrete. In the winter, ECC can be heated by passing an electric current through it, thereby preventing ice buildup. The cost of the electricity needed is substantially lower than the cost of the de-icing salt we currently use.
Taxpayer: But construction costs for ECC are much higher than for standard concrete, so your proposal is probably not justifiable on economic grounds.
Which of the following, if true, could best be used to support the highway official's proposal in the face of the taxpayer's objection?
选项:
A、The use of de-icing salt causes corrosion of the reinforcing steel in concrete bridge decks and damage to the concrete itself, thereby considerably shortening the useful life of concrete bridges.
B、Severe icing conditions can cause power outages and slow down the work of emergency crews trying to get power restored.
C、In weather conditions conducive to icing, ice generally forms on the concrete surfaces of bridges well before it forms on parts of the roadway that go over solid ground.
D、Aside from its potential use for de-icing bridges, ECC might also be an effective means of keeping other concrete structures such as parking garages and airport runways ice free.
E、If ECC were to be used for a bridge surface, the electric current would be turned on only at times at which ice was likely to form.
答案:
A
提问：
请唐塘老师回答：您之前说过问题两个人，后面的人重要，所以这道题我就去看了支持taxpayer的观点的，因此一直在选项里找跟钱相关，选了D。后来听了这个题解题：说问题问的是支持第一个人观点选项。所以我搞糊涂了，到底两个人出现哪个重要？
