请教gwd 一道逻辑题

zhaozihan

1-14Guidebook 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?

A 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.

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

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

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

E The average length of apprenticeship for carpenters has declined significantly since 1930     答案是d 怎么理解

1.原文大意：

    因为——1930前的木匠比1930后的好

    所以——1930前的木器比1930后的好

实际上，该逻辑就是“木匠好，所以木器好”

要削弱结论，就要否定“木器好的原因是木匠好”，也就要找到其他导致木器好的原因。

D的意思是：质量越好的木器，越不会遭到弃用和毁坏。也就是说，质量越好的木器，越可以保存得好。反过来，保存的好是木器好的原因。

如果考试时想不通的话，直接用排除法也可以。

个人觉得D是说木工活越好的建筑，越不会被毁坏。而木工活不好的建筑很难继续存在。而题目中in those buildings包括很多年的木工活的建筑，也就说明这些木工活的质量都好，而不能说明1930年的好。

 the quality of original carpentry应该说的是木工活的质量，而不是木头的质量the quality of the wood／materials
