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

答案说是A,可怎么觉得A 说的是反的呀？1990的light rainfall和moderate rainfall都是少的，但是total rainfull却是多的，那不就是它的heavy rainfall要多吗？怎么选A 的呀？

题目问的是哪个选项可能，BCE是不可能了。D也不可能，需要一点乘法运算，90年中雨天里降水量总和怎么也不能多于10年的两倍以上。

A可能，因为即便90年无雨的天数多于10年，但只要每次下雨时，雨量都比10年同一级别的下雨天的降水量多，尤其是大雨天，降水量不封顶，所以年降水量还是可能大于10年20％以上。
