马上考试！求助一道ＧＷＤ上的题目，以前的讨论未果！

5. GWD30-Q5:

Citing the recent increase in earnings by several computer companies, economists feel that a cycle has begun in which personal computer users, especially corporate consumers, are replacing their PC’s with more powerful models.

A.      a cycle has begun in which personal computer users

B.       a cycle for personal computer users has begun in which they

C.      there is a cycle beginning for personal computer users

D.      it is the beginning of a cycle for personal computer users

E.       personal computer users are in the beginning of a cycle when they

答案选Ａ，但是我觉得　in which 修饰a cycle，但是隔的这么远也行吗？

而且A的选项,用personal computer users指代they,将代词改为名词,是正确答案的标志,这是我上XDF,老师说的.

谢谢啦！
