maybe this is the reason that A is wrong??

              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

(E) not only by what patients eat but also by when they eat it

A and E both use " by when", so it shouldn't be a reason to rule out A.

Also in A, "them" unambiguously refers to "foods".

But in E, there is no reference to "it", which might be "the food". how can a pronoun refers to a noun that doesn't appear on the sentence?

Why E is correct but A is not?

A的错误：not only by+名词，but also by+从句。

E正确因为绝对平行。

我认为c中time前是否应有："the"

不能因为平行就选定答案；OG204就是最好的例子。

如果E中的it指代有问题，E的语法错误就很严重，必须排除；

A中并没有语法错误，只是形式上不对称，偶认为这题应该选A，希望大家能找出新的论据

OG204. In recent years cattle breeders have increasingly used crossbreeding, in part that their steers should acquire certain characteristics and partly because crossbreeding is said to provide hybrid vigor.

E. partly to acquire certain characteristics in their steers

Any more comments?

我也不是太明白，when引导的是名词性从句吗？

本来觉得没什么，选的是E。

一看讨论，反而

大家是不是对指代过于敏感了？

it到底直待什么? 是不是 what. 而非what patients eat整个句子

是否可以这么说：逻辑意思〉平行〉指代？
