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

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
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
1990的moderate rainfall和light rainfall的天数都比1910少,可是1990的total rainfall却比1910多20%,那么只有1990的heavy rainfall的天数比1910多才有可能啊。为什么选A呢?我选的是D,虽然我觉得也有点牵强,但却是这里面最好的了。。。大家觉得呢?

heavy rain没有给出上限,只是说大于2 inches,所以可以做极端假设,某天来了洪灾,即使1990heavy rain的天数不及1910,但是一次足以超过1910的所有heavy rain的total amount

但是不是说possible怎么怎么样啊?D的情况是可能的啊!!!
还是不理解~~~~~~

B,C都不可能,因为两者跟题干信息矛盾;
D不满足题干中20%的信息;
E如果满足了题干结论就错了。
A虽然一眼看上去是错的,但是是有这个可能的,理由和serene的一样,因为可能出现极端天气。
用排除法,最后选A

D,在1990年中雨天数比1910少的情况下,其降雨量不可能超过1910的2倍。因为1inch<moderate rainfall <2inches,即最大的中雨量不超过最小的中雨量的2倍,也就是:即便1990的中雨天每次都是最大量,而1910的中雨量每次都是最小量。
so D is not right
