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

答案选A  感觉有点不对啊   哪位nn能帮忙解释下  谢谢

这题关键在于问的possible，只能排除法了：bcde明显不可能。

对a的解释：有这个可能性：大雨的天数不在多，在于一次如果下的量够大 ，也能达到最后目标。
