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?

正确答案: D

GWD1-13原来的讨论贴没有答案~再来请教大家

GWD1-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?

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

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.

答案说是D,我是真的想不通啊~D难道不是支持么?说退休搬到别州的总人数增加,说明可能会对佛州these business造成不好影响啊~

我选了A。因为佛州比其他州吸引更多的退休职工,虽然percentage有所下降,但还是会有更多的退休人来~所以不会对那些商业造成影响~

D我是真的认真想了很久也没有想通啊~盼大家指点!

题目说,过去十年来,退休后转移到佛罗里达州生活的人的percentage下降了,并且在佛州local businesses很多是由这些退休的人开的,那么最后得出结论:这个decline很可能对这些businesses有负面影响

问题是找出那个weaken的选项

我在这里要打断一下这个题目要选择D有一个常识性的假设就是只要来佛州的退休的人数多了,那么对于经济就是有正面影响

那么既然问题是要找weaken,就是找出一个选项来说明其实佛州的经济不是变坏反而变好了

那么看D,D的意思是退休后并且转移到另外一个州(注意这里的another是指他们退休前所在的州,而不是说除了佛州之外的州)的总人数大幅增加,那么这个人数就是基数,那么可以知道只要这个基数增加的足够大,就算那个percentage下降了一些,退休后到佛州的人一样会增加,所以就能说明佛州的经济是会变好,所以D是削弱

A的问题在于虽然它说了佛州比别的州相对来说吸引更多的人,但是它比错对象了,我可以说就算佛州吸引相对别的州来说更多的人,可是如果总人数基数不增加的话,最终实际上来佛州的退休者还是会变少,那么还是对经济有负面影响,仍然不能削弱,所以A没有D好,选择D

这是典型的相对值-绝对值得题目 用绝对值削弱相对值 文章逻辑“%下降-->人数下降”用绝对值削弱人数没有下降

其他的选项都是无关的!

谢谢小麦克的解答!

恩,我是把another state当成除佛州之外的其它州了~现在想想就明白很多了~

但照你的解释,因为退休而要迁移的总人数增加,其实A在这里也充当了隐含假设,即使总人数增加再多,但退休的人并不愿意去佛州的话,还是没用的~

ANYWAY,问题解决了~谢谢啦
