Rail Executive: Five years ago we discontinued train service between Lamberton and its suburbs because low ridership caused total fares collected to be substantially lower than the cost of operating the service. it is true that recent population growth in the suburban communities suggests increased potential ridership, nevertheless since most of the newer residents own automobiles, restoring the train service this year would still result in serious deficits.

Which of the following, if true casts the most serious doubt on the rail executive’s argument?

Which of the following, if true casts the most serious doubt on the rail executive’s argument?

A: once train service along a given route has been discontinued, there are substantial start-up costs associated with restoring service along that route.

B: most of the new residents of Lumberton’s suburbs do not need to travel into Lamberton regularly for shopping or recreation

C: if train service were restored this with increased hours of service there would not be an increase in total ridership

D: A survey conducted last year showed that few people living in Lamberton or its suburbs support increased public funding for mass transportation

E: Recently there have been sharp increases in parking fees in Lamberton and in highway tolls on major commuter routes.

正确答案选E我不否认 可是做了很多题 经常会因为根据选项继续推导下去 也就是2次推导 而产生错误

这道题的E选项说是什么停车费增加了 目的是说明不会有更多的人会用私家车了 这样削弱了结论 我这样理解应该没有错吧？

而这样理解的话 会不会有二次推导的嫌疑呢？？？如果单单 看E这个选项 而不去推导的话 是很明显的无关选项阿

小弟不才 请NN们指导~~~~

在削弱命题时,不存在无关,只要能对命题或结论有削弱效果都是可以的~

第一次听到二次推导这种说法~  很新颖~
我自己理解的LZ的意思应该是对选项进行过多的联想而产生错误，是吗？
如果是这样的话，1次推导在哪儿？看了你的分析，你的1次推导好像仅仅是在翻译了E选项，而所谓的2次推导其实才应该是1次推导，因此，感觉LZ多虑了哈~
