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?

1. Florida attracts more people who move from one state to another when they retire than does any other state.


2. The number of people who move out of Florida to accept employment in other states has increased over the past ten years.


3. There are far more local businesses in Florida that cater to tourists than there are local businesses that cater to retirees.


4. The total number of people who retired and moved to another state for their retirement has increased significantly over the past ten years.


5. 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.

??是么?

sorry, 我没注意到结论的经济影响是针对these businesses（即cater to retirees），所以C中的cater to tourists 无关，如果结论是negative economic effect on LOCAL businesses。则答案为C。所以该题答案应为D。就是说，虽然PERCENTAGE减少了，但总人数增加了，所以来Florida 的退休人员还是可能增加，WEAKEN结论。

D是对的，感谢GAOSHISAN和TULIPMONTREA

I go to answer A.

according to answer D, even though the total numer of people retired has increased, they still move out of the state of Florida therefore, the local business who cater for retireness will not benifit from the increased amout of people.

In Answer A.  it says Florida attracts more people coming into the states( than the other states do),  which provides more customers ( business) for the local business. Thus, it weakens the assumption that the local business will be harmed by a smaller amount of retirement from Florida residents.

A比较错误。要跟自己的过去比较，不是跟别的州比较。

我也认为是A.

同意。因为说的是本州的趋势比较。
