83. 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
答案：B
问一个弱智的问题，这个句子的成分是什么呢，为什么后面a phenomenon 感觉后面就是一个定语从句，整个a phenomenon 到后面不是一个完整句子而是一个部分呢，这样也可以吗

是定语从句，the phenomenon抽象名词做同位语修饰整个前句
