[提问Helr大叔] 对prep逻辑笔记101-方案推理题的疑问

童小旻

首先膜拜一下您的逻辑方法，感觉非常好用！！！而且你讲课很好玩儿啊哈哈~~我就用不吃饭的方式减肥哈哈哈~~

101.     

Crowdingon Mooreville’s subway frequently leads to delays, because it is difficult forpassengers to exit from the trains.  Overthe next ten years, the Mooreville Transit Authority projects that subwayridership will increase by 20 percent. The authority plans to increase the number of daily train trips by only5 percent over the same period. Officials predict that this increase is sufficient to ensure that theincidence of delays due to crowding does not increase.

Whichof the following, if true, provides the strongest grounds for the officials’prediction?

A.The population of Mooreville is not expected to increase significantly in thenext ten years.

B.The Transit Authority also plans a 5 percent increase in the number of bustrips on routes that connect to subways.

C.The Transit Authority projects that the number of Mooreville residents whocommute to work by automobile will increase in the next ten years.

D.Most of the projected increase in ridership is expected to occur in off-peakhours when trains now are sparsely used.

E.The 5 percent increase in the number of train trips can be achieved without anequal increase in Transit Authority operational costs.

这道题你对E的解释是题目中已经限定了评估方向是可行性，弱弱的问一下。。。为什么限定了呀

谢谢！！！！

Officials predict that this increase is sufficient to ensure

这里的sufficient表示的是“足够的”，也就是说题目仅仅问你的是，下列哪一项是足够能保证计划成功达到目标的。题目本身就不要求你考虑副作用。也就是说，只要能可行就行，不考虑其他问题。

这里的sufficient表示的是“足够的”，也 ...

谢谢！！嗯，我再体会一下哈~~
感觉这种限定和转基因棉花的那道题里面那个藏在论证里的“被虫子严重破坏 ”那种限定很像
实战里还都挺难找出来的
