请教几道语法题~

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
E. with its superiority to the horse having been

答案选B，但我觉得有点问题，为什么要用had been？为什么C不对？按照并列句的省略，C选项的was不是可以省略吗？

2. In an effort to reduce their inventories, Italian vintners have cut prices; their wines have been priced to sell, and they are.
A. have been priced to sell, and they are
B. are priced to sell, and they have
C. are priced to sell, and they do
D. are being priced to sell, and have
E. had been priced to sell, and they have

答案选C。解释是 到现在为止已减价have cut prices, 所以现在定价销售are priced to sell 并且有销路 sell. 我对C选项的they指代有疑惑，照答案理解的话they应该是说wines，但前面的their不是指的是vintners么？还是说这里的they和their指的是不同的？

另外想问问大家，宾语从句并列的时候，and后面的that还需要吗？比如说 sth.  showed that ... and that... 第二个that要吗？是否可以省略？一直对并列句的省略有疑惑，做白勇的语法解析的时候看到有的题省略了，有的题又没省，头大。

小女子问题比较多~谢谢大家帮忙解答啦。。。

1。Once the economic and social usefulness of the motor car was demonstrated  这已经是个独立的句子了，后面的and是句子的并列了。所以C就不对了。

c项的was不能省，因为主语不一样，一般是主谓都一致才一起省 had been 可能是要表达和前面事件的发生先后顺序吧  我觉得they应该指代vinters，如果指wines为什么后面不用被动a

继续讨论

我知道 卖的好就是sell呀，可是为什么他是指代wines.

XXXXXY

按逻辑意思，如果they指wines，意思是wines被定价并且买的好 如they指vinters意思是wines被定价销售，酒商确实做了。 第一个好点吧      
关于代词的指代不同问题 应该有些特例吧 并且有分号隔开 两分句在语法上有独立性吧

看了白勇，指示代词与物主代词指代不一致的情况很常见，但相同的指示代词在一句话中必须指代同一个名词，如两个they；一个they和一个them等。
