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.

这道题的答案是D，有哪位高人能讲解一下么，小弟不才，做错后觉得是不是说“退休后去Florida的人数占退休总人数比重下降3%，而由于总人数剧增，使得实际上去Florida的人数反而增加了”呢？是在不太明白，请帮忙指正。

关键： weaken
A.    Florida attracts more people who move from one state to another when they retire than does any other state.
与other state比较  无关

B.    The number of people who move out of Florida to accept employment in other states has increased over the past ten years.
people who move out of Florida 无关
有关也是support

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

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

the percentage who retired to Florida has decreased
total number of people who retired and moved to another state has increased
所以total number of people who retired and moved to Florida就不一定啦 所以结论削弱～

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.

太谢谢啦，当时我没有理解“the percentage"是指相对于总数而言，而误以为是“the percentage of people who retired and moved to Florida"…………现在总算明白啦。
