Question

一道四级单选题
In general,the amount that a student spends for housing should be held to one-fifth the total___ for living expenses.
A) acceptable
B) available
C) advisable
D) applicable
请问选项怎么都是形容词?空格处不应该加名词吗?

Answer 1

这个题目是选B
是说每个月要花5分之一的钱用在住房上面
available做后置定语.
可以这样理解the total that is available 省略了
