OG CR 困惑 求帮忙解答~

双双儿

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 D说明了现存旅馆不具有代表性，但我觉得质量好的旅馆被保存下来并不能说明问题，如果1930年以后也有质量这么好的不也会被保存下来吗？文中说1930年前的比1930后的好，就说明好到可以留下来的旅馆，1930年前就是比1930年后好呀... 1930年后都没有这么好的旅馆可以留下来... 我知道其他选项的错误都在哪，就是想不通D，昂...是不是有点钻牛角尖了 如果能解释的求各位帮忙看看
