标题: GWD-29-Q35？？

1. GWD-29-Q35

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

不太明白……

一共4中天气，2种都比1910少，还一种是不下雨的，下雨的总量又比1910多。肯定heavy rainfall的天数多啊。。。

heavy rainfall 是超過2 inches量，所以表示，不一定要下比較多天，可以一天下超多雨，照樣還是會有較多的雨量。所以A沒錯。
