OG11紫-47

47．The financial crash of October 1987 demonstrated that the world's capital markets are integrated more closely than never before and events in one part of the global village may be transmitted to the rest of the village-almost instantaneously．

(A)  integrated more closely than never before and

(B)  closely integrated more than ever before so

(C)  more closely integrated as never before while

(D)  more closely integrated than ever before and that

(E)  more than ever before closely integrated as

答案是D，原因是此处有平行结构：The 1987 crash demonstrated two truths：that the world's capital markets are integrated．．．and that events…may be transmitted．其他选项均因为这个被否掉。

我的问题是，E选项中用as连接两个从句构成因果关系，共同作为demonstrated的宾语，为什么就不对呢？
