Q41:

The greatest road system built in the Americas prior to the arrival of Christopher Columbus was the Incan highway, which, over 2,500 miles long and extending from northern Ecuador through Peru to Southern Chile.

1. Columbus was the Incan highway, which, over 2,500 miles long and extending

2. Columbus was the Incan highway, over 2,500 miles in length, and extended

3. Columbus, the Incan highway, which was over 2,500 miles in length and extended

4. Columbus, the Incan highway, being over 2,500 miles in length, was extended

5. Columbus, the Incan highway was over 2,500 miles long, extending

这题的答案是E.但我有一个问题关于A: A的错是which吗?是不是which,that等引导定语从句的先行词出现,后面一定是完整的句子,不可以省略谓语? 所以A错在漏了was?

如果,该选项去掉which,应该对了吧?

A选项里面which后面不应该有逗号,而且which后面带的句子缺乏谓语.
