Which if the following, if true, most logically
completes the argument?

Aroca
                County’s public schools are
supported primarily by taxes on property. 
The county plans to eliminate the property tax and support schools with
a new three percent sales tax on all retail items sold in the county.  Three percent of current retail sales is less
than the amount collected through property taxes, but implementation of the
plan would not necessarily reduce the amount of money going to Aroca County
public schools, because ______.

A.   
many Aroca
                County
residents have already left the county because of its high property taxes

B.   
a shopping mall likely to draw shoppers from
neighboring counties is about to open in Aroca
                County

C.   
at least some Aroca
                County
parents are likely to use the money they will save on property taxes to send
their children to private schools not funded by the county

D.   
a significant proportion of parents of Aroca
                County
public school students do not own their homes and consequently do not pay
property taxes

E.    
retailers in Aroca
                County
are not likely to absorb the sales tax by reducing the pretax price of their
goods

原来的学校用的是财产税，现在财产税取消了，改为销售税

E说零售商降低了税前的商品价格，导致税收少了，并不能支持原文

A是说因为原来财产税高，所以很多人都搬走了，财产税收入也降低了，现在改为销售税，多以应该不会比原来财产税少，

自己理解是这样，望还有大牛解答！
