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.
the protein in rice is higher quality than that in
rice has protein of higher quality than that in
the protein in rice is higher in quality than it is in
rice protein is higher in quality than it is in
rice has a protein higher in quality than
In this sentence, the initial clause modifies the nearest noun, identifying it as the thing being compared with wheat. By making protein the noun modified, choices A, C, and D illogically compare wheat with protein(是指In addition to having more protein than wheat does这个从句里面) and claim that the protein in rice has more protein than wheat does. In C and D, the comparative structure higher in quality than it is in wheat absurdly suggests that rice protein contains wheat. B, the best choice, logically compares wheat to rice by placing the noun rice immediately after the initial clause. B also uses that to refer to protein in making the comparison between the proteins of rice and wheat. Choice E needs either that in or does after wheat to make a complete and logical comparison.
从E可以看出，用than that in wheat或than does wheat都可以

上面是prep08的解释，但我总觉得B怎么都不平行。。虽然E感觉有点歧义；所以没答案！！！我猜是不是改版后删掉这题的原因。。
