114. 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.

答案是D
实在看不出跟题有啥关系啊
难道1930后的carpenters不懂好质量能保证building不disuse吗？？？？？？
既然30前的都知道，那30后的会不懂这个道理吗？
太扯了吧

还是我理解有误？？？
