请教~~~

1.Alaska regularly deposits some of its profits from the sale of oil into a special fund ,with the intention to sustain the state's economy after the exhaustion of its oil reserves.

A.fund ,with the intention to sustain the state's economy after the exhaustion of its oil reserves.

B.fund ,the intention of which is to sustain the state's economy after they have exhausted their oil reserves

C.fund intended to sustain the state's economy after oil reserves are exhausted

D.fund intended to sustain the state's economy after exhausting its oil reserves

E.fund that they intend to sustain the state's economy after oil reserves are exhausted

请问为什么不可以选择B呢？

2 Bryon possessed powers of observation that would have made him a great anthropologist and
            that makes his letter as a group the rival of
        the best novels of the time .

答案把这部分改成了make his letters as a group the rival of

请问这个题目中that 从句修饰的是observation 还是powers?

新东方的老师在解释这个答案说只所以用make是因为省略了would ~~请问在什么情况下前后重复的部分可以省略掉~~~貌似有些情况下省略掉相同部分会被认为是前后结构不对称的错误~~

1题中的B,THEY 没有指代对象.

2新东方老师讲的对,这里把WOULD HAVE省略了.

Q1 which不能指代前面一个句子，另外就是2楼说的They的指代有问题

Q2 2楼给解释错了不是省略了would have 如果是省略了这个，还原后就成了would have make 严重的错误！所以是省略了would。

在助动词相同的情况下是，通常可以把助动词省略

mm看看这个

多谢提醒~~~

是不是最终结论就是with the intention of 这个固定搭配的问题呢？我认为intend 是用来修饰fund的~~
