Please help me with this CR question
Guidebook writer: I have visited hotelsthroughout 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.
(0 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 oforiginal 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.
