[求助]LSAT-5-2-6

搜了 死个人搜不到

The Transit Authority’s proposal to increase fares by 40 percent must be implemented. Admittedly, this fare increase will impose a hardship on some bus and subway riders. But if the fare is not increased, service will have to be cut severely and that would result in an unacceptably large loss of ridership.

The passage employs which one of the following argumentative strategies?

(A) It offers evidence that the recommended course of action would have no undesirable consequences.

(B) It shows that a proponent of any alternative position would be force into a contradiction.

(C) It arrives at its conclusion indirectly by providing reasons for rejecting an alternative course of action.

(D) It explains why the recommended course of action would not be subject to the objections raised against the alternative.（C）

(E) It justifies the conclusion by showing that such a course of action has proven effective in the past.

我有一些困惑，就是做LSAT这种题目（什么逻辑攻击的策略啦，什么攻击的方法啦）的时候总是做不对，似乎是因为逻辑关系分析不清楚的缘故，有没有大牛能够稍稍点拨我一下 谢谢！！！

我选C

答案是什么？

答案就是C啦~能请分析一下做这个题目的思路么~？

Here we have only two choices : increase( the conclusion)     not increase

According to the passage, the author drawed  the "increase" conclusion by showing the  undesirable consequences "not increase" would bring about(providing reasons for rejecting an alternative course of action)

thus ,in turn support the "increase"choice (indirectly)

btw  A be subject to B =(1)A be affected by B  (2) A depends B happening before A can happen

clearly D is not the answer

呜……我还是没办法分清楚C和D，我觉得两个都是对的啊

作者确实拒绝了另外一个选项从而选择了一个选项，但是作者的手段也确实可以看做是比较了两个选项，说明了第一个受害的人少些，第二个受害的人多些，确定了第一个不会比第二个差然后给出结论嘛……

还是不懂啊请您在解释一下C选项和D选项到底有什么本质区别好么~谢谢~
