标题: prep08 123 一点点疑问 求解答！！！谢谢~~ [打印本页] 作者: willingyue 时间: 2015-4-8 17:11 标题: prep08 123 一点点疑问 求解答！！！谢谢~~ 123. 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 我也选出来了（因为其它选项明显不能选） 可还是对D这个选项有点疑问：退休后从一个州搬到另一个州的总人数增加 并不代表搬到Florida的总人数增加吗？The total number of people who retired and moved to another state for their retirement说的似乎是整体情况（比如说的是整个国家的情况） 可并没有明确说明搬到Florida的总人数增加 求解答！！！

楼主的意思是对的呀，不知道楼主在纠结什么。
相对数增加（减少），绝对数未必是增加（减少）；反之亦然。
文章明显说了搬到佛罗里达州的人数的百分比下降了3%，比如原来10%，现在就只有7%了，那总人数增加了，自然搬到佛罗里达州的人的人数怎么样都不可能减少的啊......原文已经很明确说了是下降3%的，你随便带个数进去试一下
