50. 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.

(A) That educators have not anticipated the impact of microcomputer technology can hardly be said that it is their fault

(B) That educators have not anticipated the impact of microcomputer technology can hardly be said to be at fault

(C) It can hardly be said that it is the fault of educators who have not anticipated the impact of microcomputer technology

(D) It can hardly be said that educators are at fault for not anticipating the impact of microcomputer technology

(E) The fact that educators are at fault for not anticipating the impact of microcomputer technology can hardly be said

OG中的解释为：

B Can hardly be said to be at fault does not grammatically complete the subordinate clause

请NN帮忙解释一下，为什么说B中的从句不完整呢？

谢谢。
