Great explanation chenlong.

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.

2。The number of people who move out of Florida to accept employment in other states has increased over the past ten years.

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.

请nn看看到底是选什么。我觉得D是正确的

A的错误在于，即使F吸引的人比其他州都多，但是和自己相比，还是减少了，所以不能weaken；

C是无关啊，不是说得these business吗？那cater tourrists对retired有什么影响？

另外 我觉得即使不是针对these business，C也不正确。C还是存在gap，并不能说cater tourists多，经济就会好啊。

我支持选D!

我觉得D是相对正确的答案.但是D也有点牵强...The total number of people who retired and moved to another state for their retirement has increased significantly over the past ten years.但是并没有说就会去FLORIDA州呀,还有一个问题我一直没搞懂,E中的left是离开,但是不是也有剩下的意思吗?
            I left my key here
            不就是说留下的意思吗?如果E中The number of people who left Florida翻译成留在FLORIDA的人数呢?那么E不就正确了吗? 我的愚见,请NN鉴定

以下是引用chenlong在2006-9-5 12:55:00的发言：

题干说：在退休后移居到另一个州的人中，移居到弗罗里达的比例在过去十年中下降了三个百分点；因此，在佛罗里达州，与退休人员直接相关的经济受到了损害。

上述推理事实上有一个gap，即：到底（与退休人员直接相关的经济的）消费者是减少了还是增加了？只有消费者减少了，经济才会受到损害；如果消费者并没有减少，那么经济就不会受到损害。我们来看选项：

1. Florida attracts more people who move from one state to another when they retire than does any other state. 完全存在一种可能，即：尽管与其他州相比，佛罗里达目前仍然吸引了最多的退休移居者，但退休移居至佛罗里达的人数正在下降，导致当地针对退休移居者的经济下滑。因此，此项事实不能削弱。
2. The number of people who move out of Florida to accept employment in other states has increased over the past ten years. 题干针对退休移居者，该选项说的是到州外去工作的人，因此是无关选项。
3. There are far more local businesses in Florida that cater to tourists than there are local businesses that cater to retirees. 题干限定于针对退休移居者的经济，该选项说到了真多旅游者的经济，因此是无关选项。
4. The total number of people who retired and moved to another state for their retirement has increased significantly over the past ten years. 此题指出基数增加，因此比例下降也未必导致实际数量下降。假设，根据题干，在全美国范围内，退休后移居到另一个州的人当中，移居到弗罗里达的比例在过去十年中从10%下降到了7%（下降了三个百分点），但（根据该选项），退休移居者总数从100万增加到200万，那么显然，在过去十年中退休移居到佛罗里达的总人数从10万增加到了14万，显然会促进当地退休移居者经济的发展。当然，这是一个例子，仅仅为了说明在本选项成立的情况下，题干中的推理并不成立。

我也选了D.总人数上升了即使比例下降,实际人数也是在上升的.

A不对,虽然FL比其他的州吸引的人多,但是和他自己比,人数在下降啊(前提是总人数不增多),既然人数下降那么必然会影响到跟退休有关的产业的.要和自己比,不能和别的州比
