[求助]GWD-TN-19-Q18

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?

A.    Money collected from property taxes provided most of Altonville’s revenue during the past four years.

B.    The percentage of Altonville’s overall revenue that was collected from property taxes did not change over the past four years.

C.    Altonville officials had proposed raising property tax rates during the past four years but never did so because of strong opposition from property owners.

D.    The total amount of revenue that Altonville has collected from property taxes has declined over the past four years.

E.     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.

这题答案是D，有点被绕晕了，能帮忙把题目思路说下吗？谢谢

一点粗解：

题干意思是房屋评估价4年内不断下调，而房屋财产税占评估价的比重不变，因此可以推导出房屋税在4年内是不断下降的。

Moreover, the percentage of assessed value that was paid as property taxes to the city did not change during this period.

粗体部分的that是指the percentage，而不是assessed value
