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.
下雨分三类：大中小，以及不下雨。
过去几年内，中小的下雨量减小，但是总降水量变多，题目问的是可能的情况而不是一定的情况，因此排除法会更好
BC；中小肯定是减少的
D已经说了1990年中雨数量减少，肯定不可能是两倍了
E总降水量已经变多了，天数不变，平均量肯定是增加的
至于A是可能的，天数减少了，但是平均每天的降雨量变大
