向各位大牛请教一道语法题

际遇2011

OG10-19. In addition to having more protein than wheat does, the protein in rice is higher quality than that in wheat, with more of the amino acids essential to the human diet.

(A) the protein in rice is higher quality than that in

(B) rice has protein of higher quality than that in

(C) the protein in rice is higher in quality than it is in

(D) rice protein is higher in quality than it is in

(E) rice has a protein higher in quality than
答案是B，可是我想请教A为什么不对呢？比较双方一个是the protein in rice,  一个是 that(the protein) in wheat 这不是比B的形式更为对称么？
多谢指教！

having more protein than wheat does的逻辑主语是rice，如果后面是 the protein in rice 使得前面的修饰语 ...

真是太给力了！没想到OG通吃到这种程度！给跪了！佩服！

In addition to having more protein than wheat does是主语的modifier，所以主语必须是rice才make sense.A ...

大牛们真是让人佩服。为什么都学得这么好，让我等学渣怎么办

having more protein than wheat does的逻辑主语是rice，如果后面是 the protein in rice 使得前面的修饰语没有用处了，就是og里面说的dangling modifier

In addition to having more protein than wheat does是主语的modifier，所以主语必须是rice才make sense.A选项中主语是the protein (in rice)，蛋白质比小麦含有更多的蛋白质，doesn't make sense.
