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
我選C,可是答案是E. 但E中的symptomatic 是形容詞,跟illness與pyhsical condition無法對等,還請大家指教.
