OG13 86题
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.
OG86
(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

我纠结了好久这个句子的结构，一直找不到主句（主动词）在哪。。。

我的理解是 In 2000，（phenomenon 的同位语从句), a phenomenon（that 开头的定语从句）
结果整个句子就只剩一个 a phenomenon...

应该是‘that’我没有理解好，求指教！！

a mere two dozen products accounted for half the increase in spending on prescription drugs, 主句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.同位语
two dozen products 主语 accounted for 谓语

自己想了想，查了查，觉得是那个 that 是同位语从句的引导词，后面不是定语从句，是主句。

整个句子本来应该是
A phenomenon (that in 2000,...) is explained not only by fact... but also by fact ....

结果同位语从句（in 2000... drugs) 被提前了，就把that留下了

主句就是 A phenomenon is explained。

请指正！

前面句子是主句，后面是a phenomenon引导的同位语从句
概括性同位语：用一个概括性的名词去概括前面的修饰对象：句子，n. +that...

我认为是 a phenomenon是the increase 的同位语

phenomenon不是前面一整个句子的同位语吗
