GWD这个D感觉有点不太相关~

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 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D，人家说原因是skill好，可即使这个他因D，感觉也不算他因吧，大不了就说了质量好呀，都没说是其他具体原因（比如好skill）导致的，大家说说看！

d项说的是房屋本身的质量与存在时间的关系，而原题中说的是盖房子的人的性质，这两个应该算不同的原因了吧...
