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?
(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 signifi cantly 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 signifi cantly since 1930.


我选的是B  我觉得1930年之后住的人多了房子被损坏了他因导致1930年之后的房子看上去 1930年之前的好  而非木匠工艺问题  
选D是调查对象不具代表性 能理解 但是为什么说B不能削弱呢。。/(ㄒoㄒ)/~~  求助！

D 不是不具代表性，就是说质量差的都倒了，留下的是好的。B不要YY哦，人多了就损坏了得不出~~

文中Guidebook writer 的观点认为以前的木匠技艺比后来的更精湛. 题目问weaken , 答案的逻辑是，因为质量好的才留下来，质量差的更有可能被拆了。 这就叫以面概全，你不能拿以前的好的跟现在的差的比，你就说以前的就都是好的了，对吧？
