一道匪夷所思的题：og12 sc-87

sagamba

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

答案选的是C 。看og勉强理解是parallelism，但是，这句话到底是什么意思啊？谁看懂了吗？中文意思。

sagamba
