讨论一道不费脑子的题吧

wuyw2010

A study published in the British Medical Journal showed that women who ate nuts more than five

times a week were about one third less likely to suffer from coronary heart disease as those who

ate no nuts at all.

(A) as those who ate

(B) as women who ate

(C) as those eating

(D) than women eating

(E) than were those who ate

PREP笔记上的，首先完全同意后面的解释说明，但并不消除我对DE两选项的疑惑，D错误的理由是该选项中，由于缺少系动词were，构成less likely to suffer from A than B，宾语AB之间比较的歧义，这个我觉得结构上是会歧义，但人脑子也得动下吧，不可能suffer from B，也就是说逻辑上并不会引起理解的歧义。英文的思维是不是不能这么转呢？

两点理由
1.that women who ate nuts more than five，those who.
--parallelism

2. 想到了less likely to suffer from A than B很正确，但想的太多就不正确了。
就算你说我们可以稍微动下脑子想想，那么为什么不选脑子都不用动，就知道没问题的E呢？
