GWD-5-2

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?

1. 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.
   
   
   
   
2. Hotels built since 1930 can generally accommodate more guests than those built before 1930.
   
   

   
   

3. The materials available to carpenters working before 1930 were not significantly different in quality from the materials available to carpenters working after 1930.
   
   

   
   

4. The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished.
   
   

   
   

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

Here, I wonder why B is wrong? Could anybody please help me with my puzzle?

Thank you!

答案是舍么?

我感觉B hotel 可以容纳更多人since1930  似乎与skill, care, and effort 无关

我选D  不知 对不对

I think "Hotels built since 1930 can generally accommodate more guests than those built before 1930" also can explain why the quality of the carpentary work in the hotel built after 1930 are better than in the hotel built before 1930.That's so say, it's caused by the usage rather than the skills.

Am I right?

Could NN please give any help?

Thank you!!

ok, I see, what B says is about the capacity of the hotel . If we say that "Hotels built since 1930 have generally accommodated more guests than those built before 1930"

I think that it can serve as a key.

Any comments?
