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.

题目讲的是退休后去佛罗里达的人的“比例”少了，然后说这种减少对那里的经济会有负面影响

问削弱？

答案A：佛州比其他的州吸引更多的退休者；---题目中没有这种比例出现，无关选项

答案D：退休后移民到其他州的人的总数增加了，所以即使去佛州的比例少了，但是人数很有可能不变或者增加了，因此虚弱

比例小了，但基数大了，结果还是可能变大的。

恩，看来群体的力量是巨大的，有时候自己钻到牛角尖里出不来了。
