标题: 关于which引导的非限制性定语从句
我想问一下which引导的非限制性定语从句是不是不能指代前面一个句子，比如GWD5-Q39
In 2000, a mere two dozen products accounted for half the increase in spending on prescription drugs, a phenomenon that is explained not just because of more expensive drugs but by the fact that doctors are writing many more prescriptions for higher-cost drugs.

A. a phenomenon that is explained not just because of more expensive drugs but by the fact that doctors are writing

B. a phenomenon that is explained not just by the fact that drugs are becoming more expensive but also by the fact that doctors are writing

C. a phenomenon occurring not just because of drugs that are becoming more expensive but because of doctors having also written

D. which occurred not just because drugs are becoming more expensive but doctors are also writing

E. which occurred not just because of more expensive drugs but because doctors have also written

的DE错的原因？

是的，虽然以前高中老师说可以。。。。但是GMAT说不可以
具体可以参考OG11 SC71题的解释
