GWD1的第13题：

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D，不懂

GWD4的第14题：

Guidebook writer: I have visited hotels throughout the country and have noticed that in those built before 1930 the quality of the original carpentry work is generally superior to that in hotels built afterward. Clearly carpenters working on hotels before 1930 typically worked with more skill, care, and effort than carpenters who have worked on hotels built subsequently.

Which of the following, if true, most seriously weakens the guidebook writer’s argument?

The quality of original carpentry in hotels is generally far superior to the quality of original carpentry in other structures, such as houses and stores.
Hotels built since 1930 can generally accommodate more guests than those built before 1930.
The materials available to carpenters working before 1930 were not significantly different in quality from the materials available to carpenters working after 1930.
The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished.
The average length of apprenticeship for carpenters has declined significantly since 1930.

答案D，可是我觉得应该选B

求助大家~~

for 13

The total number of people who retired and moved to another state for their retirement has increased significantly over the past ten years.

这个是分母，分母大了，所以percentage for Florida小了，不代表Florida的这个数字小了，所以不能说影响当地经济

14题我也不懂，谁能解释一下

13。是因为比例和数字的差异。

原文说的是比例，但打个比方。过去有100个人，有50%的人搬去F，那么有50个人。但现在有1000个人，虽然比例下降到了47%，但是有了470个人。所以是对原文的削弱。看到原文中比例，很多时候是用与数字的差异进行削弱的。

14。B选项是无关选项吧。能招待多少客人和原文中说的木匠的手艺并没有关系吧。

B:因为住的人多了，所以1930以后的质量比1930之前下降了，而不是因为手艺的好坏，这个不是可以削弱原文的结论吗？

我觉得D那个，手艺越好越少破坏，其实是加强了结论啊~

还是不懂
