［无名氏的每日一题］2014年11月6日

刚刚接触GMAT的时候，CD论坛给了我很多帮助，最近在整理GWD的题，索性也来个每日一题。其中我会尽量减少对选项的解释，因为我觉得考试的时候没什么时间对选项做非常详细的思考。另外，我在每道题中也会加上自己对CR的一些总结。我选的标准是以GWD24套题为蓝本，删去了BF题。但愿能够坚持着把24套题贴完了。

GWD-1-13 In the United States, of the people who moved from one state to another when theyretired, the percentage who retired to Florida has decreased by threepercentage points over the past ten years. Since many local businesses inFlorida cater to retirees, this decline is likely to have a noticeably negativeeconomic effect on these businesses.
Whichof the following, if true, most seriously weakens the argument?

A.    Floridaattracts more people who move from one state to another when they retire thandoes any other state. 所谓下降是要和F州之前比，比较的对象错误。

B.     Thenumber of people who move out of Florida to accept employment in other stateshas increased over the past ten years. 很明显无关。

C.    Thereare far more local businesses in Florida that cater to tourists than there arelocal businesses that cater to retirees. 原文是在说退休人数减少对经济的影响，与旅游者的作用无关。

D.    Thetotal number of people who retired and moved to another state for theirretirement has increased significantly over the past ten years.

E.  The number of people wholeft Florida when they retired to live in another state was greater last yearthan it was ten years ago.

原文的逻辑关系是：因为来F养老的人百分比下降（the percentage who retired to Florida has decreased），所以这对F依赖于退休老人的商户有负面影响（this decline is likely to have a noticeably negative economic effect on these businesses）。然后问削弱。
      A.    Florida attracts more people who move from one state to another when they retire than does any other state. 涉及到了来F的退休人数，但是比较的范围不对，原文是比较F过去和现        在，而A是比较F和其他州。比较范围的错误巨尼玛常见。

B.     The number of people who move out of Florida to accept employment in other states has increased over the past ten years. 找工作，和退休的无关。

C.    There are far more local businesses in Florida that cater to tourists than there are local businesses that cater to retirees. 来旅游的，都是打酱油的。

D.    The total number of people who retired and moved to another state for their retirement has increased significantly over the past ten years. 正确。原文说百分比下降，这个选项说总体上升。这个和常见的价格和成本的关系很类似。

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. 离开F的人，无关。
