GWD-4-Q14:

    

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.
