查了一下好像不是大权的题，记不起从前从何处DOWN的题。Anyway, 请帮忙分析一下。

Most insomnia is not an illness or a physical condition so much as a symptom of another problem that may simply be a reaction to certain medications, anxiety about travel, or stress before a job interview.

A. an illness or a physical condition so much as a symptom of another problem that may simply be a reaction to certain medications

B an illness or a physical condition so much as symptomatic of another problem that may be a simple one, like a reaction caused by certain medications

C so much an illness or a physical condition but a symptom of another problem that may be as simple as when certain medications cause a reaction

D so much an illness or a physical condition, but it is a symptom of another problem, maybe a simple one like certain medications causing a reaction

E so much an illness or a physical condition but symptomatic of another problem, maybe simply a reaction to certain medications

the given key is E.

我选A。

1. not so much XXX as是固定用法，如果XXX较长，可以放在so much之前。"not so much but" unidiomatic；=>CDE 错

“used to say that one description of someone or something is less suitable or correct than another ” （Longman)

2. symptomatic是形容词，和illness/physical condition不平行=>BE错

呵呵，我也认为是A.
