CR88-97题

Trancorp currently transports all its goods to Burland Island by

truck. The only bridge over the channel separating Burland from the mainland is congested, and trucks typically spend hours in traffic. Trains can reach the channel more quickly than trucks, and freight cars can be transported to Burland by barges that typically cross the channel in an hour. Therefore, to reduce shipping time, Trancorp plans to switch to trains and barges to transport goods to Burland.

Which of the following would be most important to know in determining whether Trancorp's plan, if implemented, is likely to achieve its goal?

A. Whether transportation by train and barge would be substantially less expensive than transportation by truck

B. Whether there are boats that can make the trip between the mainland and Burland faster than barges can

C. Whether loading the freight cars onto barges is very time consuming

D. Whether the average number of vehicles traveling over the bridge into Burland has been relatively constant in recent years

E. Whether most trucks transporting goods into Burland return to the mainland empty

答案：

题干：T公�

�目前用卡车往B岛上运送货物。但是连接B岛和大陆的唯一一座桥目前很拥堵，卡车通常需要好几个小时才能通过该桥。而火车可以比卡车更快运送货物到达海峡边，同时驳船可以将集装箱在一个小时内运过海峡。所以，为了节约运输时间，T公司计划将卡车运输改为用火车加驳船的方式进行运输。题目：下面哪个选项在我们考察这个计划的时候是需要确定的因素。分析：计划考察型的中立逻辑。正向反向逻辑对题干逻辑的影响均需要考察，同时PLAN类型的重点，计划目的必须明确，是节约运输时间。选项A, 谈成本，无关属性，排除！选项B，是否有其他比驳船更加快的船只，我们只考察将卡车换成火车加驳船这个计划的实施是否能达到节约运输时间的目的，并不是在优化现有的计划，所以B错误！选项C，装卸驳船是否非常耗时，这是影响到我们运输时间的一个关键因素，假如是的话则题干计划的逻辑错误，取否的话题干计划的逻辑是顺利可行的。正确选项D，通过桥梁的车辆平均数在近年是否相对稳定，无关属性，排除！选项E，运送货物的卡车是否空返，无关属性！
