标题: 求助GWD-29-Q35
这道逻辑题大家看看,怎么也看不出正确答案来呀.感觉全不对啊.NN 帮助看看!
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 Patton
City
- 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

Answer :A
作者: auroratian 时间: 2008-6-16 19:22
I think it should be D
if A is right,then it can not be "total rainfall for the year was 20 percent higher in 1990 than in 1910".

这个题目选A
例如, 1910年有10天 Heavy, 每天是3 inches, 1990有5天 Heavy, 每天是30 inches..问题解决了, 虽然天数少, 但是降水多
D选项不对, M定义为 1<M<2, 如1910年都比 1 inches多一点点, 哪怕无限接近1,
1990是1910的两倍, 降水量超过2inches了, 那就是H, 不是M了...所以D选择是错的

Stavan,thanks.
your explanation on the detail difference bwteen H&M is correct.
Yes,you are right. A is the correct answer.

这题,我当时没注意题干的问法,说it is also possible
,而不是说从上文归纳出什么来.明白了.谢谢!

同意!
我当时做这题,开始也晕菜了,后来发现只有A说道heavy rainfall,虽然不同意A的说法,但还是选了,心里总觉得别扭。
看到LS的解释豁然开朗啊~

没看明白!既然H\M\L的天数都少了,还怎么20 precent higher啊?题目又没有说每天降雨量多。
不懂
作者: vivian0331 时间: 2009-8-2 15:19
是不是这样理解:
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.
题干已经蕴含了矛盾:1990的day少,但是total rainfall 20% higher,也就是或题目隐含了1990每天降雨量多。也就是说题目告诉你1990比1910per day降雨量多,求下面可能的选项:
A. the number of days with heavy rainfall was lower in 1990 than in 1910
因为per day降雨量多了,所以有可能h days也少了。
请问是这样理解么?

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 Patton City
A.the number of days with heavy rainfall was lower in 1990 than in 1910
B.the number of days with some rainfall, but no more than two inches, was the same in 1990 as in 1910
C.the number of days with some rainfall, but no more than two inches, was higher in 1990 than in 1910
D.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
E.the average amount of rainfall per month was lower in 1990 than in 1910
这道题的玄妙之处在问题,问的是可能性,BCDE根据题目条件推导都不对,只有A答案有这种可能,一道陷阱题~~~~

以下是新东方老师写的答案,很好!
已知:heavy rainfall > 2 inches; 2>=moderate rainfall > 1; 0<light rainfall<=1 且 1990年小雨和中雨的天数都比1910少,然而1990年全年的降雨量还比1910多,那就只能是1990年的大雨天数比1910多,一般我们都会这样的预估,但选项恰恰没有该项。迷茫中,看到了D,误以为找到了救星,正好落在了出题者的陷阱之中。
细看该题所问“If the statements above are true, then it is also possible that in Patton City”,原来并非是由原文推出选项的导出题,而是一道怪题;只要是“可能的”项就是正确的。换句话说,依据原文,有四个选项是绝不可能的,只有一个是可能的。
那再看D,在1990年中雨天数比1910少的情况下,其降雨量可以超过1910的2倍吗?绝不可能——因为2>=moderate rainfall > 1,即最大的中雨量不超过最小的中雨量的2倍,也就是:即便1990的中雨天每次都是最大量,而1910的中雨量每次都是最小量,那么D都不能成立。
而B与C明显与已知条件矛盾(“1990年小雨和中雨的天数都比1910少”)
而E与“1990年全年的降雨量还比1910多”冲突
看来也就A有希望了;但A与我们的预估相反。
但A的确是可能的,这一点人间惆怅客和其楼上的新浪网友都有很好的解释。说个最极端的情况,1990年只下了一天雨,那是一场万年不遇的亿寸豪雨,其降雨量可以远远超过1910年的天天小雨、中雨或so so 大雨。一天就超过365天这有什么不可能的呢?
其实这题一点也不难,就是怪,思路逆向而走,在狭缝中寻找可能空间;看到这里,各位看官霎时领悟,真可谓:“忽报人间曾伏虎,泪飞顿作倾盆雨”

只需注意问题中的possible即可
问的是原文皆真的情况下,下列哪种情况是可能的,显然A
作者: 小羽羽 时间: 2010-10-7 12:16
看明白了,是选有可能正确的,不是一定正确的,与归纳题还是有一定区别的
BCDE都与题中给出的条件不符
