Q14:

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

这道题答案给的D。我选E。认为E是他因削弱，quality变差不是因为carpenter不敬业，是因为要求完工的时间短了。大牛指点。

那个apprenticeship是学徒期啊，我今天才查字典

关于D的一点愚见：1。首先the more, the more的结构一般是不对的，因为就我做过的题目来看CR很难接受从文章推出线性成比例关系。2。造得木工技艺越好月不容易坏，这应该加强的说。难道说是：造得越好越难更新，不利于城市建设。这明显违反CR的白痴原则啊。错了两次了，各位看帖的隐身牛帮衬一下啊……

D说的是质量越好,用的越勤. 也就是说正是因为1930年之后的质量好,所以用的多,当作者去看的时候,当然质量就不如1930年之前的了(因为1930年之前的质量不好,用的不多)

E说学徒期,是无关的. 因为题目的reasoning是:现在的质量好--->建造时的质量好,技术高什么的. 是明显的现象-->结论型

要反驳的话应该就其现象来讲. D就是反驳了arguer的现象
