Q13:
In the United States, of the people who moved from one state to
another when they retired, the
percentage who retired to Florida has decreased by three percentage
points over the past ten years.
Since many local businesses in Florida cater to retirees, this
decline is likely to have a noticeably
negative economic effect on these businesses.
Which of the following, if true, most seriously weakens the
argument?
A. Florida attracts more people who move from one state to another
when they retire than does
any other state.
B. The number of people who move out of Florida to accept
employment in other states has
increased over the past ten years.
C. There are far more local businesses in Florida that cater to
tourists than there are local
businesses that cater to retirees.
D. The total number of people who retired and moved to another
state for their retirement has
increased significantly over the past ten years.
E. The number of people who left Florida when they retired to live
in another state was greater
last year than it was ten years ago.
