请教12th OG ，SC 57th

请问OG 12 上Sc的57th 的B选项为什么错啊？解释说该句不完整，为什么啊？
That educators have not anticipated the impact of
microcomputer technology can hardly be said that it
is their fault : Alvin Toffler, one of the most prominent
students of the future, did not even mention
microcomputers in Future Shock, published in 1970.
(B) That educators have not anticipated the impact
of microcomputer technology can hardly be said
to be at fault
(D) It can hardly be said that educators are at fault
for not anticipating the impact of microcomputer
technology（正确答案）

另：French wines taste better than Australian wines.请问这句话对吗？有人说对，有人说不对。同时，I eat faster than you .是对的啊。第一句话也是只有主谓，Australian wines肯定是做主语，不会产生比较的歧义啊...

B主要是形式不好，主语从句that放在句首很redundancy，最好用it形式主语代替。
另外，that...can hardly be said to be at fault
是谁at fault也不清楚

French wines taste better than Australian wines
这句话没有什么问题吧
主语比较，没有宾语，应该是不补助动词的，但是GMAT认为补了也不能算错，只要助动词合理就行
