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
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.
...这题目真是鬼 BCDE是可以确认一定错误的 A就算有可能错误也是可以选的
is possible和infer不同！只要与题目信息兼容即可（哪怕可能性不大）
只是找一个possible的结果……
D，在1990年中雨天数比1910少的情况下，其降雨量不可能超过1910的2倍。因为1inch
题目只能推出heavy rain总量1990年要比1910年多的多，但还是有可能heavy rain的天数1990年比1910年少，因为天数和雨量没有必然关系。
雨量和降雨天数不一定成正比！！！
演绎推理真的是要看清题目的要求呀
误选了B，还是仔细审题，用的排除法
虽然天数少 但是雨量超级大！忽略了这个
注意：题目问的是那种情况有可能！！而不是must be true！！
A选项仍然是有可能的 比如虽然1990年的降雨天数少 但是它下大雨的时候是真的大 超大 远远大于1910年所谓的大于
那这样的话 就算总的下雨days1990年小于1910年 但是总的降雨量1990年依然可以超过1910年
嗯，比如1990年的某个大雨天发了大水:)

用排除法。其他四个选项都是与题干矛盾、从而不可能发生的。唯有第一种还是有可能的。
原来这题不是结论提，我一直按照结论提去做；死也做不出来
woc 把题目看成削弱了......OMG
找到一个解释：it is possible that there were 20 days in 1910 with over 2 inches of rainfall, but 15 days in 1990 with much more rainfall each per day. There is no upper limit, so picking numbers should unlock this concept nicely: if 1910 had 20 days at 2.5 inches/day, and 1990 had 15 days at 5 inches/day, then more rain would still fall in 1990 (75 inches vs 50 inches, just like my recent television purchase debate) even though there were fewer days . This may seem improbable, but it is not impossible.
理解不了啊？1990的时候 M.Rain 和 L. Rain的 天数已经比 1910少了，如果选A， 大雨的天数也少的话，降雨量怎么可能比1910还多20%？
这题问的是“If the statements above are true, then it is also possible that in Patton City”，问的是“可能的”情况。。
A项的确是可能存在的，举个最极端的情况：1990年只下了一天雨，但是场万年不遇的倾盆大雨，其一天的降雨量远远超过了1910年累积的小雨、中雨或大雨的降雨量。一天的超大量就超过了365天累积的总量，也是有这种可能性的~
