想和楼主讨论一下这个题，
方案是“Trancorpplans to switch to trains and barges to transport goods to Burland.”。但是，我们发现，该方案是被论证过存在性的。前提中已经说了，选取火车和驳船的原因是他们比较快，所以该题目为因果模式推理。

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, if true, casts most serious doubt on whether Trancorp's plan will succeed?

这是我读到的材料。
但是，这不是方案推理吗？虽然前面提到了train比较快的原因，但这不属于方案的解释吗？？

这一点我分得不是很清楚 ~
