标题: 请教OG的一道SC

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 bv 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

这道题答案应该选择B，不过我对D有疑问。照理来说，D应该也算平行吧？那为什么不对呢？
那要是想平行的话，D应该怎样改写才算对呢？

请教

D的错误不在于平行不平行，在于which指代的东西不明。drugs不能occur。

GMAT里的风险结构：SVO,which。这里的which不是指代整句话，而是指代前面的名词，D里的which指代drugs,将DRUGS带入语句明显错误

受教：）！！！

所以说基本在所有情况下，都是Manhattan里面的touch rule就是说which肯定都是最近修饰的吗？~
