【求助】OG13 SC64的一点疑问

liaoming4875

Doctors generally agree that such factors as cigarette smoking, eating rich foods high in fats, and alcohol consumption not only do damage by themselves but also aggravate genetic predispositions toward certain diseases.

(A)    not only do damage by themselves but also aggravate

(B)    do damage by themselves but also are aggravating to

(C)    are damaging by themselves but also are aggravating

(D)    not only do damage by themselves, they are also aggravating to

(E)    are doing damage by themselves, and they are also aggravating

B选项中说are aggravating to与do damage不平行，抛开语意不谈，为啥这两个不能平行，不都是两个动词吗？还是说V+N与V+adj不能平行？求大神帮助。。

B 选项连平行的marker: not only.. but also 都不完整
谈何平行...

只有but also 表示转折的意思
