GMAT逻辑
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.
我选了C.我觉得C说当地的公司很多是提供给tourists的,所以retiree减少也不会影响他们的经济效益.D我就搞不明白了

D.The total number of people who retired and moved to another state for their retirement has increased significantly over the past ten years.
D的理由是 总退休及移居到别州的人口增幅惊人 即使移居到Florida的百分比下降 但是实际上移居的人可能是变多了(number*%) 这是一个数学题
100*20%<120*17%
C.的话牛头不对马嘴
题目问Since many local businesses in Florida cater to retirees, this decline is likely to have a noticeably negative economic effect on these businesses. These businesses 指的是 many local businesses in Florida cater to retirees 跟送外烩卖给游客的公司没有甚麼关联性

没想到四年了我还记得

首先翻译文章的意思是说：在美国，就在人们退休的时候会从一个地方搬到另一个地方，退休后搬到Florida 的人的百分比在过去的十年中下降到了三个百分点，由于在Florida 有许多企业都是迎合退休者的，百分比的下降很可能会有一个显著的负面经济影响对这些企业来说。
C选项的意思说在Florida 迎合旅游者的当地企业要比迎合退休者的当地企业多的多。文章中根本就没这个意思。
D项的意思说...

D项的意思说退了休并搬到另一个州的人员的总数量在过去的十年里极大的增加了。由文中可推断由于退休后搬到Florida的人少了，则到其他州的人的数量就相应的增加了。
我觉得楼下三楼的回答有点问题吧，文章中没有信息说明退休的总人数增加了吧。增加的总人数应是退休并搬到其他州的人吧？

这题的焦点在关于服务退休人员的行业，服务旅游者的行业跟他们没有关系
D的意思是说，虽然退休的人中间去弗罗里达的人占得百分比少了，但是退休的人的总数比以前多，所以退休了之后去弗罗里达的人比以前还多。
