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?

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. 答案是d。 原文的意思是“在1930前,原始木工手艺比后来hotel里的都好”,从而得出结论“1930前的木匠更有技术,更努力,相对于后来的木匠来说”。d的意思是“1930前的building里越好的原始木工手艺,他们被废弃和拆毁的可能性就越低”。 d的解释只能support“1930前的好的木工手艺仍然存在,不好的可能都被毁了”,但对文章,我觉得没起多大削弱作用。因为,d能证明1930前好的木工手艺存在,即,作者是拿1930前好的木工手艺来和1930后的手艺比较的。但仍然无法抨击一个事实“1930前的木工手艺是比之后好的”,那么这就更有理说明作者是拿1930前最好的木工手艺来和1930之后的木工手艺相比较。那么我的问题就来了“作者是拿1930前最好的木工手艺和1930之后的最好的木工手艺相比较呢还是和1930之后最差的木工手艺相比较呢?”如果是前者,那么d选项就起了加强的作用,想想看,拿最好的和最好的比,当然能说明哪时期的木匠厉害。但如果是后者,那么d就起削弱作用了,因为你哪最好的和最差比,当然没法比,所以结论就有问题。 因此我的困惑就是,我们应该如何知道作者是那1930前最好的木工手艺和1930之后的哪个层次(最好,最差)的木工手艺比呢?谢谢大侠们
