GWD-29-Q17

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

 

The information above most strongly supports which of the following?

 

1. The percentage of Altonville’s yearly revenue that comes from money collected in property taxes did not change over the past four years.
2. The percentage of Altonville’s yearly revenue that comes from money collected in property taxes has declined steadily over the past four years.
3. The amount of revenue that Altonville collected from property taxes was lower last year than it was four years ago.
4. During the past four years, Altonville officials increased tax rates on other sources of revenue such as retail sales and business profits.
5. Altonville will soon require property owners to pay a higher percentage of the assessed value of their property as property tax.

我来解释一下

此题的论证过程是：房价的总产值在近几年来降价。 我们的city property tax （accesss value）也会减少。就是比如房子的总价少了，首付款也少了，所以access value的比例没有变。 （现在房价低了，首付还是30%， 比例不变）

我们来找个增强，预测应该是将首付款的.

B不对，因为此句强调很steadily的decline.

C对，强调了，减少。
