I have visited hotels throughout 求解

缺氧

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.

这是OG12-CR114题，答案的确是D而且也解释得通：D说的是有好质量的carpentry的building不容易被拆毁，也就是说那些有差质量carpentry的building就会容易被拆毁，所以导致越老留下来的building中的carpentry质量越高，削弱了题目的结论。   但是我认为在D选项这个解释比较牵强，不像别的题目的解释非常有说服力。

不好意思啊，其实我还没看懂。你是说用他因法吗？就是说其他原因是质量，不是人的原因。还是晕晕的，谢谢了

If D is true, then what the author observed was simply the consequence of "whatever is the best would survive!"  So the reason to see better carpentry in old hotels is that old hotels with bad carpentry no longer exist. If this is true, the author's argument falls apart.
