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.

答案是D。我选的A。
我的问题是：如D所说，如果所有的州退休人员搬去其他州的人数都增加了，那么说明Florida迁移到其他州的退休人员也增加了。那么，对于减少了3%来说，应该是strength吧？

而A：如果Florida在所有州中吸引的退休人数是最多的，那么，3%虽然是下降了的百分比，但是，相比来说也是最乐观的。

跪求牛人解答~~~~~~

答谢啦。

文章是削弱     moved from one state to another when they retired百分比的下降     推出了 have a noticeably negative economic effect on these businesses            主要是绝对和相对的问题         相对比率的下降不意味着整体人数的下降    D说people who retired and moved to another state人数增加了就起了削弱作用    A是无关比较   与原文无关···
