两道OG题求解~~（一道语义，一道which的用法，还有关于选项的排除问题）

olinak

一个是OG2015的91题 ，语义不懂
91\ In an effort to reduce their inventories, Italian vintners have cut prices; their wines are priced to sell, and they do.
这个主要是读不懂意思，还有这是用了什么句式呢？最后一个they为什么指的一定是酒呢？不会引起歧义吗？（理解成人）

另一个是OG2015的113题 全划线
正确选项是：
A baby emerges from the darkness of the womb with a rudimentary sense of vision that would  be rayed about 20/500; an adult with such a vision would be deemed legally blind.
选项E我不明白错在哪里？
E：As a baby emerges from the darkness of the womb, its rudimentary sense of vision, which would deemed legally blind for an aduly, would be rated about 20/500.
是which错了吗？非限定性定语从句中的which修饰的到底是最近的名词还是主句的主语、还是前面的整个句子呢？

最后，题目的几个选项里，如果一个选项没有完整的传达出其他选项表述的所有的内容，是不是就可以排除了呢？

求牛牛们作答~~~

their wines are priced to sell, and they do.

Italian wine sellers have cut prices of their wines because they want to reduce their stock. They have priced their wine such so that they sell, and the wines actually sell because of this reduced price.

第二个题目，我觉得句子顺序错了吧。要先说是20/500,再说对成年人怎么样。
不然这句话的意思就不通顺了。

which指代的是sense of vision，vision不能deems blind，人才能blind，指代错误。

they指代的一定是最近的复数名词吗？如果不是指代的最近的复数名词，指代的是更靠前的名词，就是指代错误，可以这样理解吗？
