各位大大，可以請教為什麼答案是D嗎？看起來D似乎沒有weaken ㄟ

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 business in Florida cater to retirees , this decline is likely to have a noticeably negative eccoomic effect on these business .

Which of the following , if true , most seriously weakens the arguement ?
A. Florida attracts more people who move from one state to another when they rertire 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 thar 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.

[習慣仔]

論點著重於 percentage points decline

若總數 (total number of people who retired) 增加

結論就被推翻了...

Hope it help...


P.S. by the way, the subject should be changed to GWD1-Q13
