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.
题目分析：A说hotel的木工质量高于其他建筑物的质量，原文没有说过这种比较，杀。B说能容纳更多的人住，扯得就更远了，杀。C说1930年前所用的原材料和1930年后用的原材料没什么不同，两种原材料是否有差异原文没有提及，杀。D说建筑物木工活质量越好，这个建筑物也不会被废弃，原文反复谈的是木工质量和建筑物质量之间的关系，信息和原文有交叉，留着。E说学徒的平均时间，没提，杀！
