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.
情景:略。
推理:本题的结论句为:these declines are likely to have a noticeably negative economic effect on these businesses and therefore on the economy of Florida。那么,为什么结论会是佛罗里达州的经济有影响呢?经济受到影响的真正原因是退休到佛罗里达州的人数变少了。因此,推理文段的真正前提和结论为:
前提:到佛罗里达州退休的人下降了3%。
结论:到佛罗里达州退休的人数下降了。
推理文段的前提是百分比,结论是实际数字。
选题方式:略
选项分析:
A选项:在退休的时候,佛罗里达州比其他州吸引了更多人。本选项讲的是佛罗里达州和其他州吸引人的能力的区别,不涉及百分比和实际数字的关系,可以排除。
B选项:离开佛罗里达州而在别的州谋生的人的数量在过去十年上升了。本选项没有提到百分比和实际数字的关系,可以排除。
C选项: 在佛罗里达州的吸引游客的商业机构比吸引退休人员商业机构多多了。本选项没有提到百分比和实际数字的关系,可以排除。
D选项:Correct. 过去十年内,在退休时从一个州移动到另外一个州人数上升了。若实际移动人数上升,那么就算是移动的百分比下降,实际人数依然是有可能上升的。因此,本选项指出了百分比和实际数字之间的区别,可以保留。
E选项:在退休的时候离开佛罗里达州而去其它州的人数比10年前上升了。本选项描述的是从佛罗里达州向外移出的人数,和本题讨论的推理关系没有任何联系,可以排除(本题是用移入的百分比推导出移入的退休人数,和移出无关)。
解析有误加一答案项说反了
解析内容有误,请更正。
- 解析的C选项说的是题目D选项的内容。
- 那么这道题是应该选D吗?原题的C选项说的是tourist的事情,和retiree无关。
- 题目解析中的结论句和原题的结论句不一样,多了【and therefore on the economy of Florida】这几个字,而原题并没有这几个字,这两个结论的意思是不一样的。
这题选项和解释不一致。
这个题型分类应该属于哪个呢?傻傻分不清
C 的选项应该是The number of people who moved from one state to another when they retired has increased signifi cantly over the past ten years.
