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

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

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

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

4. 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

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

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
