set 3q 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.
E. The average length of apprenticeship for carpenters has declined significantly since 1930.

i picked it from one the forums

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 - - we need to explain the differenece in quality before and after 1930s, thus clearly OUT

B. Hotels built since 1930 can generally accommodate more guests than those built before 1930 - it means that they are bigger, but nothing is said about the quality of work - - - OUT.

C. The materials available to carpenters working before 1930 were not significantly different in quality from the materials available to carpenters working after 1930 - -This strenghens the conclusion by saying that the materials were the same quality.

D. The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished - It means that Hotels with low quality carpentery works may be were already demolished and therefore we see just high quality carpenetry works in Hotels that avoid demolishing - weakens, However if we accept that it could apply to the buildings before and after 1930's proportionally, I would say that this answer choce should be taken just if all other are clearly out of scope.

E. The average length of apprenticeship for carpenters has declined significantly since 1930 - has nothing to do with quality before and after 1930, moreover it could even strenghen argument if we understand it as the averidge length of carpenter's trainings, at the initial stage of their professional carrier, declined after 1930.

D..is the best among the worse answers, therefore D.

This CR was so simple yet had uncommon logic/explanation. I was leaning towards B using the method of elimination. But after reading the explanation in the other thread it makes sense for D. Good question that is likely wrong for everyone.
