Q13:

In the United States, of the people who moved from one state to another when they retired, the percentage who retired to LACE w:st="on">FloridaLACE> has decreased by three percentage points over the past ten years. Since many local businesses in LACE w:st="on">FloridaLACE> 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. LACE w:st="on">FloridaLACE> attracts more people who move from one state to another when they retire than does any other state.
2. The number of people who move out of LACE w:st="on">FloridaLACE> to accept employment in other states has increased over the past ten years.
3. There are far more local businesses in LACE w:st="on">FloridaLACE> 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.

请教了，为什么答案竟然会是D？真的不明白

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
