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

B
OG 说 Choice E needs either that in or does after wheat to make a complete and  logical comparison
then it means the followings r all correct:
1 rice has protein of higher quality than that in wheat
2 rice has a protein higher in quality than that in wheat
3 rice has a protein higher in quality than wheat does

my question is :在1里面protein 前面为什么不需要冠词？protein是可数n.

我认为在这里：不用或用a均为泛指；若用the就不正确了，因为1）the前无先前提到过的名词，2）特指某种蛋白。
欢迎继续讨论！
