标题: [讨论]XDF补充材料上的最新机考题（三）

267．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 laceName w:st="on">PattonlaceName> laceType w:st="on">CitylaceType>

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.

Key: A

觉得A中lower应该改成higher 才对吧，如果1990年高/中/低雨量的天数都比1910年的要低，总雨量怎么可能会大于1910年呢？

请大家讨论。

除A外，其它选项必错。故A为答案

明白了。不管是300 inches还是3 inches，都是heavy，所以有可能也会出现即使90年heavy的天数比10年的少，但某些天雨量特别大的情况，因而90年的总雨量会更多。

谢谢啦！
