是不是答案给错了,请教一道GWD题~~

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

这题答案怎么可能是A呢?

题目不是说了在90年,无论是中雨还是小雨的天数都比10年少,而结果是90年的整体雨量比10年多啊,,,那A不是刚好无法说明么...我选了D,思考时是想从降雨量来补题目的缺,,,是不是答案给错了呢? NN们能否帮我看看,这题我都遇到好多次了,好象答案一直给的A...~~~~

没有错，就是A,注意题目问法，possible说明有可能对，是限制性的，也有可能错，所以用排除法做更好，排除一定错的。再有就是注意一下数字的范围，用极限的方法想一想。

楼上具体解释过喽。

A the number of days with heavy rainfall was lower in 1990 than in 1910 天数少了，但是heavy rainfall没有上限，想下多少下多少，所以有可能对。
