GWD 1-13， 可能很愚蠢的问题。。

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.

为啥答案是D， 不是C呢？ 如果旅游业大大超过退休者商业， 那么总体商业就不会受大影响啊。。

特指这些cater to retirees的businesses吧

这题的d不是很明白，它说过去十年退休后到其他州生活的总人数大幅增加了，那是不是说因为总的人数增加了，所以即使下降了3%，但退休后去florida的绝对人数不一定会下降的，所以削弱结论呢？

高手请指教！

假设以前退休后搬家的人为1000人，去佛州的人为10%；现在总人数变为10000，去佛州的人降为7%，还是后者为高。

为什么答案不是E?，E说佛州自己退休的人数减少了，对州内和退休有关的企业有影响，而不是由于从外面来的退休人少了，提出他因，也是削弱。

请NN指点

前提是一个事实

结论是这个事实会导致business受影响。

如果说题目变成：

    前提：business 受影响

    结论：是由于一个事实造成的。

这样E才可以削弱。
