请教OG-120题

according to the Tristate Transportation Authority,making certain improvements to the main commuter rail line would invrease ridership dramatically.The authority plans to finance the improvements by raising automobile tolls on the two highway bridges along the route the rail line serves.Although the proposed improvements are indeed needed,the authority's plan for securing the necessary funds should be rejected because it would unfairly force drivers to absorb the entire cost of sth from which they receive no benefit. Which of the following,if true,would provide the authority with the strongest counter to the objections that its plan is unfair? C )Automobile commuters benefit from well-maintained bridges,and in the tristate region bridge maintenance is funded out of general income tax to which both automobile and rail commuters contribute. D)The roads along the route served by the rail line are highly comgested and drivers benefit when commuters are diverted from congested roadways to mass transit. 不好意思，打字太慢，上面的题目花了我好长时间。我地问题是，D固然可以，可是C也很有道理呀？既然铁路乘客承担了一些公路维修成本，那么公路司机承担一些铁路建设成本也很公平。 我的思路有那里不对？望DX指点。谢谢！

原文的有效推理是：让没有从中受益的汽车司机承担improvements to the main commuter rail line的费用不公平〉政府的计划不可行
D是一个很好的weaken答案：直接指出了汽车司机的确从中受益，推翻了原文的前提。
楼主选C是典型的扩大推理，因为推理过程中没有涉及bridge maintenance is funded out of general income tax to which both automobile and rail commuters contribute。

原题问的是provide the authority with the strongest counter to the objections that its plan is unfair而原文提到的 the objections是 Although the proposed improvements are indeed needed,the authority's plan for securing the necessary funds should be rejected because it would unfairly force drivers to absorb the entire cost of sth from which they receive no benefit. C答案与提问没有关系说得是乘客承担费用，原文的Objection针对的是司机，提出这种政策对司机不公平，D说司机其实是受益于这项政策的。

希望大家批评指正
