In Patton City, days are categorized as having heavy rainfall (more than two inches), moderate rainfall (more than one inch, but no more than two inches), light rainfall (at least a trace, but no more than one inch), or no rainfall. In 1990, there were fewer days with light rainfall than in 1910 and fewer with moderate rainfall, yet total rainfall for the year was 20 percent higher in 1990 than in 1910.

请教一道ZT

朋友发EMAIL问我一道逻辑,据说是ZT,但抱歉不知道出处


In Patton City, days are categorized as having heavy rainfall (more than two inches), moderate rainfall (more than one inch, but no more than two inches), light rainfall (at least a trace, but no more than one inch), or no rainfall.  In 1990, there were fewer days with light rainfall than in 1910 and fewer with moderate rainfall, yet total rainfall for the year was 20 percent higher in 1990 than in 1910.



If the statements above are true, then it is also possible that in laceName w:st="on">PattonlaceName> laceType w:st="on">CitylaceType>


--------------------------------------------------------------------------------


the number of days with heavy rainfall was lower in 1990 than in 1910



the number of days with some rainfall, but no more than two inches, was the same in 1990 as in 1910



the number of days with some rainfall, but no more than two inches, was higher in 1990 than in 1910



the total number of inches of rain that fell on days with moderate rainfall in 1990 was more than twice what it had been in 1910



the average amount of rainfall per month was lower in 1990 than in 1910



答案是A。 我对这个答案很困惑,请大家讨论一下。

前几天有人问过此题,我答过。其实,不该有什么困惑。说白料,这就是个大于、小于的数学题。


B\C\D\E都与 In 1990, there were fewer days with light rainfall than in 1910 and fewer with moderate rainfall相矛盾,所以不对。


A为何对呢?


因为days are categorized as having heavy rainfall (more than two inches),只有大于2 inches,都叫heavy rainfall,如果每天的heavy rainfall很大很大,比如1000 inches,那么,heavy rainfall天数少点没关系,1990总的total rainfall仍然可能高于1910


注意原文问的是also possible

此题的出题思路与GMAT完全不一样,应该没多大参考价值.


同意楼上分析,但E与最后一句不一致
