Dental caries and gingivitis can be exacerbated not only by the foods patients eat but also by when the patients eat them.
(A) not only by the foods patients eat but also by when the patients eat them
(B) by not only the foods patients eat but also by when the patients eat them
(C) not only by the foods patients eat but also by time when the foods are eaten
(D) by not only the foods that are eaten by patients but also by the times the foods are eaten（E）
(E) not only by what patients eat but also by when they eat it
答案为E。我觉得有2个问题：1)，When they eat it是时间状语从句，怎么能与what…n.性从句并列。2),it指代不清晰。所以我选C.

it 是指代what the patients eat.
when我也奇怪，可以做名词性从句。记住就得了
