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?

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. the answer is d

i choose a

because i can not figure out the meaning of d, i think d is irrelavant

D的主要意思是，质量越好的木工越容易保存，所以1930年以前保留下来的都是相对质量较好的，质量不好的已经不存在了。所以对原文一个削弱。

而A将木工和houses stores比较，属于原文没有的无关比较。
