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, these declines are likely to have a noticeably negative economic effect on these businesses and therefore on the economy of Florida.
Which of the following, if true, most seriously weakens the argument given?
87. 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, these declines are likely to have a noticeably negative economic effect on these businesses and therefore on the economy of Florida.Which of the following, if true, most seriously weakens the argument given? (A) People who moved from one state to another when they retired moved a greater distance, on average, last year than such people did ten years ago. (B) People were more likely to retire to North Carolina from another state last year than people were ten years ago. (C) The number of people who moved from one state to another when they retired has increased signi? cantly over the past ten years. (D) 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. (E) Florida attracts more people who move from one state to another when they retire than does any other state.
能理解C选项,但是感觉结论有歧义Since many local businesses in Florida cater to retirees, these declines are likely to have a noticeably negative economic effect on these businesses and therefore on the economy of Florida these declines指的是退休后搬到F的去的人的比例减少-Flordia经济衰退。 那D选项的意思是退休后离开F的人增加(同样是退休人员人数减少)-Flordia经济衰退 否定了是搬迁去F的人比例的减少引起的。也算undermine啊? 感觉结论有歧义,不懂,求教!
我刚做完这道题,我用楼主的思路想了一下,在这道题目里面,佛罗里达经济衰退是一个可能性。题目中说"are likely to have a noticeable .......“ 那么如果这道题说,已知佛州经济衰退,并且正好退休去的人比例少了。结论,正是因为退休去的人少了才引起经济衰退。那么D选项中说的离开的人多,确实是另外一种可能。
