我的思路如下,欢迎讨论
1. 读题,第一句话data,作为premise。第二句话conclusion,标志"clearly"
2. diagramming(我在草稿纸上用圆圈里面的P代表premise,圆圈里面的C代表conclusion, qual=quality)
Premise: Carp qual: bef 1930 > aft 1930
Conclusion: Carp-er work: bef 1930 > aft 1930
Possible assumption: good carp qual -------> good carp-er work
就说good carp-er work是good carp qual的必要条件
就说分析出,作者得出结论需要assume一个causal relationship.
对于大多数weaken/strengthen题目,通常都不会直接针对premise(尤其是factual data),而是针对作者隐藏的assumption,从而削弱从premise推到conclusion的逻辑力度。
3. Prephrase. 上面我分析道,正确答案大概率是攻击:
Possible assumption: good carp qual -------> good carp-er work
这是一个causal relationship,于是想到bible讲的攻击causal relationship的5种方式.... Keep that in mind while reading through the answer choices.
....
这题其实很难预测答案,因为有5种方式削弱causal relationship,而这道题的正确答案属于第5种,就是抨击data interpretation。换句话说,D是说factual data不足以支撑causal relationship.
回头看我的笔记:
Premise:
Carp qual: bef 1930 > aft 1930Conclusion: Carp-er work: bef 1930 > aft 1930
Possible assumption: good carp qual -------> good carp-er work
关键问题出在:黄颜色背景的部分,是基于一个现代人的视角的data,也就是
EXISTING carp qual: bef 1930 > aft 1930
但是,尽管我笔记漏掉了"existing"这点,我也不会miss掉D选项,因为我分析道削弱因果的5种方式,其中有一种是data interpretation. 所以看到D,我就想: Yes, this choice
is attacking the way the author interpretates the data
114. Guidebook writer: I have visited hotels throughout thecountry and have noticed that in those built before1930 the quality of the original carpentry work isgenerally superior to that in hotels built afterward. Clearly carpenters working on hotels before 1930typically worked with more skill, care, and effort thancarpenters who have worked on hotels built subsequently.[c1]
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.[c2]
(B) Hotels built since 1930 can generallyaccommodate[c3] more guests than those built
before 1930.
(C)[c4] The materials available to carpenters workingbefore 1930 were not significantly different inquality from the materials available tocarpenters working after 1930.
(D)[c5] The better the quality of original carpentry in a building, the less likely that building is to fall intodisuse and be demolished.D
(E)[c6] The average length of apprenticeship forcarpenters has declined significantly since 1930[c1]因果型结论[c2]无关[c3]没有信息说明其与木工质量的关系[c4]Support[c5]显示导致因果的资料有误。说明用现存的hotel做比较不具有代表性,因为很可能过去很多质量不好的都弃用了,剩下的都是好的。[c6]Support
我不是很明白,是说原文结论的结论有误,取而代之的应该是和质量有关的D吗???也就是D中所说的质量越好,越少demolished~是这个意思吗?也就是weaken题常用的给出的信息不正确,是这个意思吗?即才c1处是错的,weaken的就是这个~-- by 会员 bob9603 (2012/3/5 20:36:14)
