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, than it is also possible that in Patton City

(A) the number of days with heavy rainfall was lower in1990 than in 1910.

答案选的是A选项。

但是A是否印错了？

我认为应该是the number of days with heavy rainfall was higher in1990 than in 1910而不是 lower。

我认为a是正确的

total rainfall for the year was 20 percent higher in 1990 than in 1910.

与 the number of days with heavy rainfall was lower 有区别

比如说，heavy rainfall的天数比较少，但是在仅有的几天里面heavy rainfall（即雨量）很大，那么可能造成total rainfall仍然比较高
