[求助]最近一道CR真题

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

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

我选的是C.其中关系是: 分成4个雨季 heavy rainfall  >2  

                                  moderate rainfall  between 1 and 2

                                   light rainfall     <1  

                                   no rainfall

文中说相比较1910, 在1990M和L的的天数都减少了.但是总共的降雨量却增加了20%.

我认为既然小于2的天数减少了,那么大于2的H的天数就增加了.那就是C说的.

the number of days with some rainfall, but no more than two inches, was higher in 1990 than in 1910 我理解C的意思是一些雨季的天数,除了小于2INCHES的雨季,在1990比1910高. 中间的那个是同位语做解释说明的.

个人意见..也不是很确定..请拍砖.

文章应该推出heavy rainfall(more than 2 inches) in 1990 is higher than that in 1991. 但是可惜的是选项中没有这个。看看选项，我觉得A, B, C, D,都不对。如果C是more than two inches就好了。在没有选择的情况下。只好选E 了

这其实是个关于不等式的数学题，以前讨论过。

答案明显是A

为什么是A呢？

明白了，时间看错了，是1990与1910比较而不是1990与1991比较。

A

为什么选A，选A意思不是相反了吗？请帮

谢谢！如果这样就没的选了！四楼的说是关与数学的不等式，可是我推了一下，是相反的！SIGH！
