请教 OG11 SC 81 每次都做不对

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

答案是C。解释是The first complete verb phrase is 'have been priced to sell'. The second verb does not need to repeat the word 'sell' because it is understood from the first use. However, the second verb must be correctly conjugated with the understood 'sell'. They are 'sell' is not correct; they 'do sell' is correct.

不太明白og的解释：如果sell能被do代替，那说明前一句话的谓语也应该是sell，可是前一句话的谓语是are（priced to sell）。请哪位牛牛牛解释一下？另外，这个句子怎么翻译比较合适。

正確答案中表示的是

and前后their wines和they是同一樣事物

由于前一句話出現了sell，所以后面一句的sell可以省略，同時不會引起歧義

因為前面一句話的兩個動詞，priced使用的是被動語態，sell用的是主動語態。如果后一句話要表示price的動作的話，應該用they are done。

本人的觀點

恕本人愚钝，不太理解4楼的解释。为什么“由于前一句話出現了sell，所以后面一句的sell可以省略，同時不會引起歧義”？两句话明明谓语不同啊，为什么可以省略sell？
