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

目标：减少运输时间
方案：用火车和驳船运输

但是我觉得文章有论证？文章说火车到达海边比货车快，这句话是不是论证？求解大牛论证是那种？？我没办法判断是否有论证.....

Trancorp currently transports all its goods to Burland Island by truck. - A background information.\

The only bridge over the channel separating Burland from the mainland is congested, and trucks typically spend hours in traffic. - A background information.
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. – Possibilities

Therefore, to reduce shipping time, Trancorp plans to switch to trains and barges to transport goods to Burland. Line of action to achieve the Objective

Assumption – The selected option of train and barge will save time or will not exceed the time taken by trucks.
Activities such as -
a. barge loading
b. other administrative activities such as clearances , security check etc
c. barge movement time – time taken is one hour as per
d. barge unloading
Hence, it is assumed that total time taken in activities (a to d or may be more) is less than total time spent by trucks to carry out the operation.
Thus evaluate the cycle time of the selected option/ Look out for options in the same line of thought.

A: Whether transportation by train and barge would be substantially less expensive than transportation by truck. the objective is to reduce shipping time , expense is not the concern

B: Whether there are boats that can make the trip between the mainland and Burland faster than barges can beyond the plan …
C: Whether loading the freight cars onto barges is very time consuming. – Correct , need to evaluate
D: Whether the average number of vehicles traveling over the bridge into Burland has been relatively constant in recent years? So what …how it will impact the operation below the bridge
E: Whether most trucks transporting goods into Burland return to the mainland empty? So be it …objective is only to reduce shipping time

此题挺简单的和time－consume有关的只有c选项其他都是无关项
