求牛牛们看下一道逻辑题

3. GWD21-Q3:
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 deicing 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?

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

我不是牛牛。。只是菜鸟~
但是题目不是要支持哪个highway official’s proposal么所以可以读一下选项

A所探讨的问题是de-icing会造成桥的什么损坏并减少桥的寿命。原文探讨过一些关于这方面的问题，原文说
In the winter, ECC can be heated by passing an electric current through it, thereby preventing ice buildup
所以A先留着。

B所探讨的问题是严重的冰情会造成救护怎么怎么样的问题，原文没有涉及，所以扔掉。
C所探讨的问题是在冬天，冰在桥面上形成早于在路面上形成这方面的问题，原文没有说过冰在哪儿形成的早
这方面的问题，所以C扔掉。

D所探讨的问题除了这个什么桥以外，ECC还能在其他的什么构造上有作用这方面的问题，原文没说过ECC在其他地儿用这方面的问题，所以D扔掉

E所探讨的问题是如果ECC用的话。电流只会形成几次这方面的问题，第一个感觉是E选项原文有点关系。
但是比较一下A和E发现E代入原文后让旁观者感觉是在驳斥Highway Official的做法。而不是支持它。
所以选了A选项。

呵呵个人见解，亲再问问其他大牛牛巨牛牛什么啊。。

顶一下，思路清晰！ 牛的～

恩，谢谢大牛

我觉得这种逻辑题找出两者矛盾就行 后者的意思就是说通电除冰不好是在于安装贵， 终究还是费钱。 所以削弱他就是说不比别的方法费钱就行了。
