Q2:

    

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.

I just don't get it. Why the answer is D? Can sb. explain?
Thanks.

建议lz search 以前的讨论

D 质量越好的建筑，越不容易废置或损坏

说明了 质量不好的可能就废置或者损坏了，所以并不能说明以前的比现在的更加更好

我认为D WEAKEN的角度是:因为质量好的建筑不容易废置和损害,所以现在看到的HOTEL质量好不能说明整体好，只是看到了幸存下来的质量好的一部分而已。
