Q14:

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?

1. 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.
   



2. Hotels built since 1930 can generally accommodate more guests than those built before 1930.
   



3. The materials available to carpenters working before 1930 were not significantly different in quality from the materials available to carpenters working after 1930.
   



4. The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished.
   



5. The average length of apprenticeship for carpenters has declined significantly since 1930.

这道题选D，但我觉得这并不能weaken啊，而且disuse和demolished都是无关信息啊。我选得是C，虽然C也并不perfect，但我觉得比D好点。请指教！

原文的逻辑：30年前的饭店木工活比较好，所以30年前的木工手艺比较好。

D的意思是，因为木工活比较好，所以饭店不容易被拆。就是说，现在留下来的30年代以前的饭店都是木工比较好的，不好的饭店都被拆掉了。由论据提出了另一个结论，所以削弱。

C的意思是，木工用的材料都差不多，逻辑上是排除了一个可能的他因削弱，所以实际上是起了加强效果。

啊，恍然大悟啊，最近逻辑思维实在太迟钝了，谢谢rhod gg啊～

B为什么不行？

Hotels built since 1930 can generally accommodate more guests than those built before 1930

in those built before 1930 the quality of the original carpentry work is generally superior to that in hotels built afterward

more guests -----------inferior quality of original carpentry

但是文中结论是说以前的木匠worked with more skill, care, and effort than carpenters who have worked on hotels built subsequently.

E说明1930年以后木匠的学徒期短了,提出他因说明质量下降.也可以削弱呀?

而且更针对结论,为什么不对呢?

i agree with E.

E weakens the conclusion directly.

i agree with D. E又没说更短的apprenticeship造成了木工活儿不好呀。更何况还可以理解成更短的apprenticeship造成了提早出师的木匠们技巧等各方面要弱了，这实际是对论点的strengthen

Agree with D,

E actually strengthen the conclusion.

选D, E 说木工做apprentice的时间少了，学的少了，自然skill少了，所以支持了作者的结论，而不是反驳

我想问:木工活和木工手艺有什么区别啊?
