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

这道题选A就有点说不过去了，大家认为呢

我觉得A是可以的吧，其他的都可以排除。B选项与文中的状况是相反的，C选项则更是相反，D也是不可能的，M雨的inches是大于1小于2的，如果more than twice，那么即使1910是1也会使1990的大于2，与文中相反，E选项也是不对的，如果每个月都小，则乘以12也不会大于总体的。而A选项是可能的，虽然M雨和L雨的days少，但是如果1910的M雨每次1.1 inch，而1990的是1.9 inch，那么1910的5天，1990的4天，还是会大于的，所以可以选A。

LZ看看对不，加油！

支持A;

条件比较的都是days of rainfall;结论却是total rainfull;降雨的天数少并不代表降雨的总量少
