[問題]大全 885 Section 10. 15

[Tianne]

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
(E) with its superiority to the horse having been

大全上的答案是C
查了longman
superority後頭似乎沒有加to的用法呀
這裡應是superiority over吧
是從superior to過來的嗎??

還有
its superiority to the horse proved
是省略were的關係嗎??
its superiority (were) to the horse proved
但and連接下，be動詞能被省略嗎??

麻煩一下啦!!

前面已經有個was了，所以後面的was可以省略，只不過很少看到這種用法。
