Q35:


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>




  • the number of days with heavy rainfall was lower in 1990 than in 1910

  • the number of days with some rainfall, but no more than two inches, was the same in 1990 as in 1910

  • the number of days with some rainfall, but no more than two inches, was higher in 1990 than in 1910

  • 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

  • the average amount of rainfall per month was lower in 1990 than in 1910

  • 答案是:A。好奇怪啊,既然light 和moderate都低,而总降水量高于1910,那么the number of days with heavy rainfall was higher in 1990 than in 1910而不是lower 啊。不明白了,我选的C。

    heavy的定义是高于2inch,那么可以是下2公里深的雨,那么存在一种可能性是1990年heavyrain只下了3天,比1910年下30天的每天2inch的雨带来的雨水多。
