38: GWD-29-Q35  答案A

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

First of all,I am not a NN,here's my understanding of this question,of course it's only for your information.

For B and C,it's very easy to identiy that they are both wrong options because the condition had made it very clear that the number of days with either light rainfall or moderate rainfall are fewer for 1990 than for 1910,so combined together,it's easdy to conclude that the number of days with some rainfull are still fewer in 1990 than 1910.

E的话,因为雨的总量是1990更大,而且天数是相同的，所以平均数肯定是1990大.

D的话,因为moderate的标志是1到2之间,而且1990年的moderate天数比1910的又要少，所以1990再怎么样也不可能是1910的两倍多.(随便套一下就可以推出)

A的话还是有可能的，注意题目是问is it possible?因为有一种情况就是1990的下heavy rain的天数很少，但是rainfall都很大,然后1910虽然天数比较多,但是rainfal都只比2多一点点,所以总量上还是1990大.
