求助逻辑ＧＷＤ２９－０３５

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

、各位帮我看看，答案Ａ的选项是不是有问题呢，如果days with heavy rainfall was LOWER than in 1910 .怎么会得到结论说total rainfall for the year was 20 percent higher in 1990 than in 1910.
