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

感觉没有答案， 请各位NN帮忙分析一下

谢谢了！

这题的flaw在于percentage是个相对的概念，而“many local businesses in Florida cater to retirees”是个绝对的概念，D正好点出了这一点。

对的

感谢believer的讲解

现在理解了，生意的好坏是绝对人数确定的，而不是比例

刚开始做GWD的CR， 还是比较有挑战的

以后这样的问题应该能够避免

再次感谢believer MM
