The answer is straightforward D.
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.
WRONG:- Strengthen the argument.(B) The number of people who move out of Florida to accept employment in other states has increased over the past ten years.
WRONG:- Clever trap. The argument is about retiree. Any other subset of people (employed, semi-employed, etc etc) is out of scope(C) There are far more local businesses in Florida that cater to tourists than there are local businesses that cater to retirees.
WRONG:- OUT OF SCOPE. There can be a freaking superman living in Florida for all we care. Our argument is concerned only with businesses that deals with retiree. The ratio is businesses that cater to tourist to the businesses that caters to retiree is irrelevant. Even if there is only one shop that caters to retiree, we have to think about how the decrease in retiree population will affect it. Since this Option talks nothing about whats happening to retiree .. it is out of scope.
(D) The total number of people who retired and moved to another state for their retirement has increased significantly over the past ten years.
CORRECT:- Earlier in US there were 1000 people who moved from one state of another after retirement. Out of these 50 % came to florida (meaning 500 people came to florida) Now there were 10,000 people move from one state to another and only 10 % comes to florida (meaning 10 % of 10,000=1000 people) that came to florida.
As you can see the % is decreasing but the actual number has gone up (from 500 people to 1000 people ; there is an increase of 500). This weaken the argument. Infant it kills and buries the argument 6 feet deep in the ground.
(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.
WRONG:- this is a strengthener
