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.

请教了，为什么答案竟然会是D？真的不明白

以下是引用coopers在2006-4-12 22:49:00的发言：

one is % and another one is absolute value.

example, total retired 11 years ago was 100, 10 moved to florida, so the % is 10%

within past 10 years: total retired was 1000, 70 moved to florida, so teh % is 7%

% decreased 3% but absolute number of people increased 60

解释得好!谢谢!

但是请问A的解释为什么不可以呢?

虽然在FLORIDA退休的人减少了3%,但是FLORIDA一直都吸引其他退休的人来此生活,因此retirees services并不会收到威胁.

还是不是很明白啊

A中Florida吸引的退休人数比其他州多只是一个相对的多  不能削弱绝对人数减少的事实  可能Florida州减少了10% 其他州减少了20%
