题目信息

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

正确答案: A:the number of days with heavy rainfall was lower in 1990 than in 1910

题目说,1990年下中雨和小雨的天数比1910年少,但是1990年的总降雨量比1910年多,问那个选项描述的情况可能发生,注意是可能发生不是一定正确。这类题只能用排除法排除掉一定不可能发生的选项。

B、C说1990年降雨量小于2 inches(小雨或中雨)的天数大于或者等于1910年,显然与题目给出的已知条件相悖,排除

D选项说1990年下的中雨的总量大于1910年的两倍,由于中雨是1-2inch,即使1990年每次下中雨都是2 inch,1910年每次都是1 inch,但是由于1990年下中雨的天数比1910年少,所以不可能达到两倍,排除

E选项说1990年的月均降雨量低于1910年,题目已经告知1990年的年总降雨量大于1910年,所以平均数不可能小于1910年,排除

A选项正确。说1990年下大雨的天数比1910年少,这是有可能的,虽然天数少,但是如果每次下大雨时的降雨量都远远超过1910年,下大雨时的总降雨量还是可以超过1910年的。
