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.

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。

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.

Agree with D,

E actually strengthen the conclusion.

我想问:木工活和木工手艺有什么区别啊?
