Argument Evaluation
Situation Of those people who move to another state when they retire, the percentage moving to
Florida has declined. This trend is apt to harm Florida's economy because many
businesses there cater to retirees.
Reasoning Which of the options most weakens the argument?'The argument draws its conclusion from
data about the proportion of emigrating retirees moving to Florida. Yet what matters
more directly to the conclusion (and to Florida's economy) is the absolute number of
retirees immigrating to Florida. That number could have remained constant or even risen
if the absolute numbers of emigrating retirees itself increased while the proportion going
to Florida decreased.

A This has no obvious bearing on the argument one way or another. It makes it more likely,
perhaps, that a person in a distant state will retire to Florida, but less likely that one in a
neighboring state will do so.
B This has no bearing whether fewer people have been retiring to Florida over the last ten years.
C Correct. This is the option that most seriously weakens the argument.
D This makes it more likely that Florida's economy will be harmed because of decreasing numbers of
retirees, but has no real bearing on the argument which concludes specifically that declines in the
proportion of emigrating retirees moving to Florida will have a negative effect on the state's economy.
E This is irrelevant. At issue is how the numbers of retirees in Florida from one year compare to the
next, not how those numbers compare with numbers of retirees in other states.
The correct answer is C.
为什么B选项就不对呢? OG的解释我也没看明白, 请大家帮忙看看,给予解惑~ 谢谢啦先! ^_^

我知道答案排除下来只能选C，但我有个疑问..题目说的是Florida的情况，但C说的是整体的，整体的也不能代表地方的情况啊，我第一次做的时候就这样把C给排掉了。。

你说的很有道理，的确这里没有特指florida
我觉得可以这样考虑：
1、此题考查的就是对于比例和绝对数量之间的差别，而对结论进行削弱，所以我们重要看此方面的条件
2、我们也可以把C当作待考查选项去分析其他选项，从而得出C选项更合理

所以，我相信没有任何一句话是不存在逻辑漏洞的，只要我们能够找到最适合的就好！

拜托,来个空格好不好.看第一句都累.原来是这题.
做逻辑的题目中,对数字,比率之间的比较要很敏感.比率增长不一定代表数字增加,反之也是这样.这可能是一个考点,养成习惯.看到比较提高警惕就好了.事先有预期也会在选答案的时候提高速度.

B说的是去年,无关选项
