这道prep08的104题 helr将它归为类比推理 请问为什么不是统计枚举（样本为D国家 而之后缩减到D国的首都）？
Nitrogen dioxide is a pollutant emitted by automobiles. Catalytic converters, devices designed to reduce nitrogen dioxide emissions, have been required in all new cars in Donia since 1993, and as a result, nitrogen dioxide emissions have been significantly reduced throughout most of the country. Yet although the proportion of new cars in Donia's capital city has always been comparatively high, nitrogen dioxide emissions there have showed only an insignificant decline since 1993.
Which of the following, if true, most helps to explain the insignificant decline in nitrogen dioxide emissions in Donia's capital city?
A. More of the cars in Donia's capital city were made before 1993 than after 1993.
B. The number of new cars sold per year in Donia has declined slightly since 1993.
C. Pollutants other than nitrogen dioxide that are emitted by automobiles have also been significantly reduced in Donia since 1993.
D. Many Donians who own cars made before 1993 have had catalytic converters installed in their cars.
E. Most car trips in Donia's capital city are too short for the catalytic converter to reach its effective working temperature. 作者: alzn2765 时间: 2015-5-31 02:01
这种现象解释题是什么类型的感觉不重要，因为原因一定在选项里，看明白选项找到原因就好了。
总之这道题的破题点就是Donia's capital 这个地方用车的特殊性。作者: xcdamon 时间: 2016-2-18 11:53
正好也做到这题
以下是根据helr 的思路： 类比推理 不是简单的两个事情相比，而是把两个事情A,B 的相同点列出来，然后给出A的一个特点， 推理B 案例也应该有这个特点 （B 这个特点是结论） 做类比题型的题目，一个快捷找到答案的方式就是选项中一定要涉及到两个案例，或者要出现和题目中两个案例完全不一样的案例。如果选项只说远离或者只涉及其中出现的案例，那就肯定不是答案
如果按照类比来说，只有E符合。
但是我是以矛盾解释题型来做。 因：新设备的require 果：ND 应该减少才对 （但是文章说是没有明显减少，即当作左边正常逻辑推理的削弱） 因果两个CQ 1 因果概括 2 是干扰因素。 正确选项放在 因果中间。起到削弱作用
A 无关选项 （不要忽略原文其他信息的暗示although the proportion of new cars in Donia's capital city has always been comparatively high） 这跟车多车少没关系，讲道理来说 就算只有一辆新车，只要装上了设备 就是减少了。
E 选项 干扰因素，因为这个设备没办法work out 放在 因果中间 导致 得不到ND明显减少这个结论。
