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?

Florida attracts more people who move from one state to another when they retire than does any other state.
The number of people who move out of Florida to accept employment in other states has increased over the past ten years.
There are far more local businesses in Florida that cater to tourists than there are local businesses that cater to retirees.
The total number of people who retired and moved to another state for their retirement has increased significantly over the past ten years.
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.

请帮忙解释下，答案好像是D.

搬到F的退休人数少了，因此，退休的服务生意受影响

D，退休到其它州的人显著增长。（这两者好像没有关系）。（它因？）

没搞懂。

原文：退休搬到F的人的百分比减少了，可能会对当地针对退休者的商业不利。
现在我们要削弱它
A就算搬过来的人比其它地方都多，但是搬来当地的人也确实在减少，这就会对当地商业造成negative effect.也就是此题与其他地区无关
B与搬出去找工作的人无关
C本题比较的是过去的针对退休者的商业和现在的，不是其他行业与该行业的比较，无关
D总人数增多，即使搬来的百分比减少了，搬来的人数也可能增加，削弱
E退休搬出去的人多了，对商业是不利的，有加强的感觉

这是典型的绝对数与相对数的考点

Persentage下将并不代表人少了

原来这样，说什么的百分比少了，然后就说什么不利了，是不对的，因为整体总

量也可能是大大增加的。
