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?

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.

Hotels built since 1930 can generally accommodate more guests than those built before 1930.

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

The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished.

The average length of apprenticeship for carpenters has declined significantly since 1930.

这一题应该怎么做？

E

A把旅馆和house等比,无关;B讲hotel的容量变化,无关;C说明两者原材料并无不同,是原文成立的assumption,加强;D讲carpentry的质量和建筑能否长久保留间的关系,无关

E,指出它因,是因为以前的人花更多时间,并不是他们用了更多的skill, care effort,所以削弱
