OG11-16 关于同位语的用法

Declining values for farm equipment and land, the collateral against which farmers borrow to get through the harvest season, is going to force many lenders to tighten or deny credit this spring.
(A) the collateral against which farmers borrow to get through the harvest season, is
(B) which farmers use as collateral to borrow against to get through the harvest season, is
(C) the collateral which is borrowed against by farmers to get through the harvest season, is
(D) which farmers use as collateral to borrow against to get through the harvest season, are
(E) the collateral against which farmers borrow to get through the harvest season, are

这里collateral作 farm equipment and land的同位语，应该起到补充说明的作用，它的作用和非限制性定语从句应该是一样的。

那么就是说 farm equipment and land 就是collateral。这样明显说不通啊，相对而言，d我觉得更加正确了。

另外还有一个问题，在搜索这道题目的时候，有的g友认为collateral是可数名次。作为同位语的话，同位语和其修饰对象的单复数可以不一致。

是这样的么，求证一下。

D错

如果是非限制定从的话，which ＝farm equipment and land

还原：farmers use farm equipment and land to borrow against请问against 什么？宾语呢？

如果你说which 是指against后面的宾语，那么use 后面的宾语是什么？

所以D是错的

E：同谓语，解释说明farm equipment and land，farm equipment and land是农民为渡过harvest season作的抵押。这里的which 仅有一个指代，即the collateral 。还原：farmers borrow against the collateral（farm equipment and land） to  get through the harvest season

有点明白了

那单复数的用法呢，

是不是同位语可以和其修饰对象的单复数可以不一致呢？

没人理我，难道我的问题有那么弱智？

不过我自己找到个例子：大全416：

In the most common procedure for harvesting forage crops such as alfalfa, as much as 20 percent of the leaf and small-stem material, which is the most nutritious of all the parts of the plant, shattered and fell to the ground.
(A) which is the most nutritious of all the parts of the plant, shattered and fell
(B) the most nutritious of all parts of the plant, shatter and fall
(C) the parts of the plant which were most nutritious, will shatter and fall
(D) the most nutritious parts of the plant, shatters and falls
(E) parts of the plant which are the most nutritious, have shattered and fallen
