which不能用于限定性从句，排除A C
at a cost of +具体数，at the cost of +doing 习语排除B
enough so that不符合习语 排除E

其实一眼望去就是纠结B和D吧
at cost/at a cost of     B 习惯用语不对
还有就是句子是HAS PROPOSED。。可能用将来时比较合适吧。。
偶也不是很清楚。。

我选错了，一开始把whose当作错误选项给排除了

“GMAT规定，who, whom 只能指人，不可指物；that 不能指代人，人只能用who 来指代”。
但是！看起来whose可以用来修饰物。

也写了“whose修饰人和物~~”

弱弱的问一句，肿么判定限定性和非限定性呢？

非限定性从句前面加逗号

laurawinter

whose those 都可修饰人和物
that 只能指物
