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.

Correct

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

Explanation:

In the guidebook of the writer, the argument about carpenters working with more skill, care and effort before 1930's than carpenters who have worked on hotels built subsequently is greatly weakened if the materials available to the carpenters were not significantly different in both years.

Had it been the quality of the materials were different, it would definitely has affected the quality of the carpentry works by the carpenters either before 1930's and after 1930's.
