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.

实在不懂 我觉得每一个选项是对的。。。。

和楼主一样

我做这题的时候也错了

我觉得关键是在理解“ the percentage who retired to Florida has decreased ”这句里面的那个“retired to Florida ”，如果把这个理解成Florida这个地方retire了的人数下降了的话，那么选D就是正确的了。因为其他地方的人retire的多了，那么move out的人也就多了，所以Florida这个地方总共的那些来的人还是很多，他的那些为retire了的人服务的行业就不会受影响

但是，我怎么也觉得“retired to Florida ”不能这样理解

所以，同请高人指教这一题

比例下降，但人口基数增加，所以总数还是增加了
