1.        Once the economic and social usefulness of the motor car was demonstrated and with its superiority to the horse being proved, much of the early hostility to it in rural regions disappeared.

(A) and with its superiority to the horse being

(B) and its superiority over the horse had been

(C) and its superiority to the horse

(D) its superiority over the horse（C）

(E) with its superiority to the horse having been

这道题白勇的语法书上答案是B, 并解释C不对的原因是 and 连接once从句和名词短语its superiority , 两者形式不对称

我做这道题选的也是 C, 因为我认为be动词可以省略

不好意思，发完贴才发现刚刚有人解释过这道题，可是我最近一直在啃白勇的语法书，他的书中有两处提到过这道题，答案都是B, 其实我也一直想不通答案为什麽是B,  but the explanation in the book is just like that.
