E 从结构上看，由于 but 前面是逗号，costing 即可以伴随前面的 took 3 weeks，也可以与后面的 using the canal 并列，是“夹心饼干”。而且 the move 不可作 in using the canal 的逻辑主语，其逻辑主语应该是人。

从整个句子的平行来看，第一个分局谓语动词 took... and cost...平行，而且这样的句子结构也与未划线部分的 took less than... and cost less than... 平行。

因此选 C

犀利  
C项的平行 是key point

另外，
A when ...was being moved ....being 明显多余 （另外,  前面的讨论说it 错误， 我感觉it 在这里做虚拟主语， 应该是没错的）
B. 第一个it 多余， Moving a ton of  .... took ..and cost....  才正确
D.E 的cost 用法都有问题

A与C比较，A中being多余。。It有指代歧义，C更简洁
supportC

lol, not as so easy.
it in A, stands for moving a ton of blah blah```it seems ok, problem lies on the before, it is confused, and should b put in the first place `````

e中的costing有修饰Erie Canal的歧义吧

C没有but做转折而是“；”作平行把原文想表达的两个分句的逻辑关系给改变了，这样可以么？

When a ton of wheat was being moved from Buffalo to New York City before the opening of the Erie Canal in 1825, it took three weeks and cost $100,
but when the canal was used, ittook less than eight days and cost less than $6.

正确答案平行得太美丽啦！

A. When a ton of wheat was being moved from Buffalo to New York City before the opening of the Erie Canal in 1825, it took three weeks and
cost $100, but when the canal was used, it it 指代不清

B. Moving a ton of wheat from Buffalo to New York City before the opening of the Erie Canal in 1825, it took three weeks and cost $100;
using the canal, it 指代不清

C. Before the opening of the Erie Canal in 1825, moving a ton of wheat from Buffalo to New York City took three weeks and cost $100;
on the canal the move和后面的took和cost平行得太美丽了！ Gmat里还有个小现象就是两个不同层次但在逻辑上有联系的句子，
用分号链接最好

D. In 1825, before opening the Erie Canal, to move a ton of wheat took three weeks from Buffalo to New York City, which cost $100;
moving it on the canalwhich错误用法，cost也改变了句子逻辑意思

E. To move a ton of wheat in 1825 from Buffalo to New York City took three weeks before the opening of the Erie Canal, costing $100,
but in using the canal, the movebefore的位置改变导致了move to new york 在opening前3个星期

cost 在原句中是动词，而E中cost 仅作为了一个分词修饰，改变句子的中心，错
