GWD1-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.
