The total market value of real estate in Altonville has steadily declined over the past four years. This decline has meant that the overall figure on which the city’s property tax is based ─ the assessed value of that real estate ─ has also declined. Moreover, the percentage of assessed value that was paid as property taxes to the city did not change during this period.
The information above most strongly supports which of the following?
Money collected from property taxes provided most of Altonville’s revenue during the past four years.
The percentage of Altonville’s overall revenue that was collected from property taxes did not change over the past four years.
Altonville officials had proposed raising property tax rates during the past four years but never did so because of strong opposition from property owners.
The total amount of revenue that Altonville has collected from property taxes has declined over the past four years.
During the past four years, Altonville officials also did not increase tax rates on other sources of revenue such as retail sales or business profits.
问题分析：文章就讲了三个事情：real estate的价值，real estate的评估价值，以及property tax，这三种东西的关系。
问题问的还是归纳，选项中不能出现和原文无关的内容，A说税收是这块收入的主要来源，这个内容显然无关·，杀。
B说overall revenue而原文最后一句中说的是从评估价中得到的，出现和原文无关的内容，杀。
C说官员建议，这个内容显然原文没提，干掉。
D说revenue多少，没有出现和原文无关的东西，留着。
E 说官员是否增加税率，这个内容没说过，干掉！
