Q2: GWD-4-14

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.

The average length of apprenticeship for carpenters has declined significantly since 1930.



答案是D，但是我怎么看怎么觉得d是加强啊。

LZ觉得不选D要选什么呢?
D削弱在于:

题目说, 总的来说1930年之前的hotel的木工活比之后的好,
结论是1930年之前 木匠盖hotel的skill, care 和 effort比随后的要好
D说木工活好的建筑不容易倒掉, 那意思就是1930年之前的hotel, 能保留至今的, 都是木工活好的, 不好的都demolished啦..
用1930年之前好的和1930年之后的好加不好进行比较, 当然之前的整体水平高,
而不是结论说的, skill, care, effort这个原因导致的, 因此削弱结论
