再次请教GWD4-14

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.
答案是D,看了大家的讨论,比较一致的说法是说D选项理解为:一个房子里的木匠活做的越好,这个房子越不可能被弃用或是毁掉。
    

因此削弱了并不是以前的木匠手艺高,而是只有高水平的才保留住了。

但是选项并没有说只有1930年前的房子才这样吧?那么30年之后的房子也有可能因质量差而被废弃,而即使在同样都有被弃的可能性之下,仍然是30年前的房子质量好些,那不就加强结论了吗,或者至少没有削弱结论啊

纠结中,等待高手解惑....

这道题讨论的是一般意义上的比较(generally)。而一般规律就是:历史越久的房子越少,而这些硕果仅存的房子所展现的建筑水平也越高。以1930为分界线,显然30年后保留的房子基数要大于30年前,从而从一般意义上体现出较低的建筑水平。

30年后的房子当然也存在一个废弃的过程,但是要注意的是这本身是一个渐进的过程,所以30年以后的房子中质量低的比例会比30年前的高,原因就是这些质量低的还正处于淘汰的过程中。
