GWD 14-13 询问

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?

 

1. Florida attracts more people who move from one state to another when they retire than does any other state. 无关的比较（F与其它州比）
2. The number of people who move out of Florida to accept employment in other states has increased over the past ten years. （支持）
3. There are far more local businesses in Florida that cater to tourists than there are local businesses that cater to retirees.
4. The total number of people who retired and moved to another state for their retirement has increased significantly over the past ten years.
5. 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. （支持）

为什么C 不对?

请大家给予赐教

绝对数和百分比之间的差异！！

就算降低了这么多的百分比，但是绝对数是增加的，可以使收入照样增加

难道选项不能不能修改原文的一个陈述从而来削弱之

There are far more local businesses in Florida that cater to tourists than there are local businesses that cater to retirees.
无关阿, 这些 business 的死活 和 原文的
effect on these businesses. 所致的business 无关阿
D 就 直接反对了结论

本來認為C對，現在看看，應該D最好。因為原文中是說，到 Florida的retiree減少，影響當地迎合退休人的business。然而在C中，僅僅比較當地兩種 business 的多寡，並無針對議題回應。

C. There are far more local businesses in Florida that cater to tourists than there are local businesses that cater to retirees.

 

我個人覺得C錯的原因是：文章已經提到Florida很多的business是迎合退休者，所以就算C提到有更多的business是迎合旅客，也不會影響到Florida很多的business是迎合退休者，所以一旦減少3%，還是會影響到經濟的。
