In Millington,a city of 50,000 people,Mercedes Pedrosa,a realtor,calculated that a family with
Millington’s median family income,$28,000 a year,could afford to buy Millington’s
median-priced $77,000 house.This calculation was based on an 11.2 percent mortgage interest
rate and on the realtor’s assumption that a family could only afford to pay up to 25 percent of its
income for housing.
Which of the following corrections of a figure appearing in the passage above,if it were the
only correction that needed to be made,would yield a new calculation showing that even
incomes below the median family income would enable families in Millington to afford
Millington’s median-priced house?
(A) Millington’s total population was 45,000 people.
(B) Millington’s median annual family income was $27,000
(C) Millington’s median-priced house cost $80,000
(D) The rate at which people in Millington had to pay mortgage interest was only 10 percent.
(E) Families in Millington could only afford to pay up to 22 percent of their annual income for
housing.
是选D,但是为什么?

这题根本就不用算.
问题是为了使低于中级消费水平的人买起房子,要改个题目中的一个数据.
A：买不买得起房子跟人口不搭界吧.
B：median annual family income减少了,那不是低层的人工资会更少,怎么可能买得起.
C：房价提升还能是低层人买得起?
D：对的.只有mortgage interest降低了,意味着交钱更少了,才有可能买得起.
E：同样道理,中层收入的拿出买房的钱少了,低层的同样也会减少.也不能使低层的人买得起房.

同学，选d么？？

确定一下问题是：修改哪个前提条件，可以推出，收入低于中等水平的家庭也可以负担中等价位的房子。
A答案是米灵顿的人口总量为45000，跟问题没有任何关系，可以排除。
B：米灵顿的中等家庭年收入是2万七千刀，文中原来的中等收入是2万8千刀，现在中等收入降低了，当然负担不起原来的价位了。错误。
C：中等价位的房子为8万刀，文中原来为7万7千刀，价位提高了，负担不起，错误选项。

C：中等价位的房子为8万刀，文中原来为7万7千刀，价位提高了，负担不起，错误选项。
D:抵押贷款利率为10%,文中原来为11.2%，所以贷款利率降低了，不需要那么多钱就可以供得起中等价位的房子了，所以，收入略低于中等收入的家庭也可以负担得起中等价位的房子了。正确选项。
E：只能拿出年收入的22%来供房，文中原来是可以拿出25%。这样就更供不起了。错误选项。
这么简单的问题，不清楚楼主是因为英文没看懂还是这么简单的道理不懂。困惑ing。都想不通这还能称为逻辑题，不需要推理的啊，像2大于1一样的浅显
