标题: GWD 19的一道逻辑题，大家帮看看为啥D不可能呢？ [打印本页] 作者: azuo1209 时间: 2010-9-26 18:01 标题: GWD 19的一道逻辑题，大家帮看看为啥D不可能呢？ 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作者: boriswang520 时间: 2010-9-26 18:53
我认为B. C .D 皆有可能。此题不严谨。作者: zhangyunkai5 时间: 2010-9-26 23:15
答案是A?作者: azuo1209 时间: 2010-9-27 10:23
没错答案是A，要是这么说的话，我觉得B,C,D 都行呢。 如果没有高人指点，我认为此题还是有争议，暂且跳过。作者: sorryself 时间: 2010-9-27 12:16
此题太绕了，大概没几个人考试能答对
但B, C, D的确都是不可能的答案
B&C选项：”the number of days with some rainfall, but no more than two inches” = the number of days with moderate and light rainfall，既然前提都说了1990年比较少，那这两个选项都不可能成立
