标题: 求助GWD1 Q13 [打印本页] 作者: 希望来得及 时间: 2010-6-29 21:47 标题: 求助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?
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. 答案为D,这道题也是OG12的87题,不过选项内容有变动。一直想不清楚,答案是怎么削弱的!希望牛人可以帮助解释一下,真诚感谢!
不是“别的州”,The total number of people who retired and moved to another state是说的US整体,退休后到别处的人在number上增多了,即使percent下降,净人口还是有可能增长的,所以是weaken。作者: cartier921 时间: 2010-7-21 18:43
请教一下A哪里错了呢?谢谢作者: x_fan 时间: 2010-7-21 19:28
解释的很好啊,我也是错了两次,看来楼上的分析很明白,不过想了一下自己错的原因,也很大家分享下,就是原句的3%没有理解到比较的对象,也就是这个题目的迷惑点,如果把句子看成, the percentage who retired to Florida has decreased by three percentage ,of the people who moved from one state to another when they retired,就豁然开朗啦。作者: momo1900 时间: 2012-2-5 23:26

百分比下降了,但人总数是上升的,所以并不能说明人就少了作者: zanqss 时间: 2015-1-14 12:56
为什么不是别的州上升是F州下降导致的吗,此增彼涨啊?所以别的州上升不能说明F州总数上升吧?作者: kmwzs66 时间: 2015-7-13 18:35
