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.
(E) in attributing a food allergy as the cause of
criminal or delinquent behavior,

(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

这题选择A,
我的疑问是，a phenomenon 指的是前面的整句话吧，可是我看的prep08等等上面的解释是，同位语从句的用法里面有一条，就是后面的名词是代替前面的那个句子里的一个名词的，象这里代替一个句子，能行吗？？？？？、很晕很晕

这是同位语的一种用法，用一个抽象的名词来概括前面的整个内容。常用的还有：a finding/phenomenon/fact/event/trend that这类词汇概括前面描述的内容

a mere two dozen products accounted for half the increase in spending on prescription drugs‘，与 a phenomenon互为同位语，是这个句子修饰 a phenomenon，可理解为a phenomenon that a mere two dozen products accounted for half the increase in spending on prescription drugs。为什么不可以呢？个人理解
