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 material 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.

A tough one, but i go with C on this one.

If the materials were the same, then maybe the carpet has been changed recently, this is why it looks so much better.

A-strenghtens
B-it's close but we don't know how many more guests can the newer hotels accomodate Could be something like 5000 vs 5500, which is not a significant difference, and in turn make the carpet go bad.
D and E are beyond the scope.

It is D.

Other reason: only the best hotels have survived since 1930.

I thing this one is D.

A. Irrelevant
B. Irrelevant
C. Strengthen: If the materials are the same then the only other factor is workmanship.
E. Strengthen: If the appreticeship is shorter then they have less training.

D. This one indicates that buildings with poor quality before 1930's were demolished. So the only buildings left standing from before the 1930's have high quality. So the carpenters could have the same skill now or even better it's just that they are only being compared to the good quality buildings that werent demolished.

Ahhh damn. I misread the argument. I understood carpet instead of carpentry.

Conclusion: Carpenters working on hotels before 1930 typically worked with more skills, care and effort than carpenters who have worked on hotels built subsequently.

(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. [This weakens the argument as carpentry in hotels is generally superior – implies less emphasis on carpenters’ care and effort – hold it]

(B) Hotels built since 1930 can generally accommodate more guests than those built before 1930. [Hotel accommodation is out of scope of the argument – eliminate it]

(C) The materials available to carpenters working before 1930 were not significantly different in quality from the material available to carpenters working after 1930. [The material available for carpenters is out of scope of argument – eliminate it]

(D) The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished.[Hotel usage is out of scope of the argument – eliminate it]

(E) The average length of apprenticeship for carpenters has declined significantly since 1930.[This strengthens the conclusion – eliminate it]

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.

[h1] hotels built before 1930
[h2] hotels built after 1930
[c] carpentry work
[c1] carpenters before 1930
[c2] carpenters after 1930

Guidebook writer: [c] in [h1] is better than [c] in [h2].
[Assumption: there are no other reasons why [c] in [h1] is better than [c] in [h2] excepting difference in skills between [c1] and [c2]]
Therefore, [c1] who made [c] in [h1] is better than [c2] who made [c] in [h2]

D. There is other reason why [c] in [h1] is better than [c] in [h2]: [h1] with better [c] is more likely survived. And therefore, now we have [h1] with better [c]

Hope this help :)
