求助：一道GWD逻辑题，我怎么也转不过来了

38: 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

1. the number of days with heavy rainfall was lower in 1990 than in 1910
   
   
   
2. the number of days with some rainfall, but no more than two inches, was the same in 1990 as in 1910
   
   
   
3. the number of days with some rainfall, but no more than two inches, was higher in 1990 than in 1910
   
   
   
4. 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
   
   
   
5. the average amount of rainfall per month was lower in 1990 than in 1910
   

为什么是A呢？DAY WITH LIGHT RAIN FALL和DAY WITH MODERATE RAINFALL 都下降，总的下雨量又上升，为什么选A啊？

太感谢了，没有你的提醒我可能一辈子也转不过弯来了`呵呵

heavy rainfall是more than two inches,没有上限,所以可能天数少,但几天里狂下,还是有可能总量大的
而C的这种情况,就是小于等于two inches,相当于moderate rainfall加light rainfall,这两个题中都已经说了是fewer了,加起来还是fewer

恩这道文字上是有点绕,我当时也想了一下的
