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 noticeable negative economic effect on these businesses.
Which of the follow, 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 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 move to another state fro 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.
Can anybody explain why D?
Premise: Retirees will move to another state (after they stop working)
Premise 2: The percentage of Florida retirees decrease 3 % during past 10 years
Premise 3: Almost businesses in Florida are serving retirees
Conclusion: This decline (decrease 3%) is likely to have a noticeable negative economic effect on these businesses.This argument assumes the retirees who originated in Florida will work for cater to retirees.
This assumption is contradict with the premise 1. The choice D states that
"The total number of people who retired and move to another state fro their retirement has increased significantly over the past ten years."
This statement means that many retirees in other states will move to Florida to use the service in retirees caters. This number will be larger than the number decrease from the 3% decrease in retirees in Florida. (This number is compatible with premise 1 subtract to the number in the premise 2) that will suite with premise 3 ==> conclusion that the business in Florida will get benefits rather than negative effects
