　　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

　已知：heavy rainfall > 2 inches; 2>=moderate rainfall > 1; 0　　且 1990年小雨和中雨的天数都比1910少，然而1990年全年的降雨量还比1910多，那就只能是1990年的大雨天数比1910多，一般我们都会这样的预估，但选项恰恰没有该项。迷茫中，看到了D，误以为找到了救星，正好落在了出题者的陷阱之中。

　　细看该题所问“If the statements above are true, then it is also possible that in Patton City”，原来并非是由原文推出选项的导出题，而是一道怪题;只要是“可能的”项就是正确的。换句话说，依据原文，有四个选项是绝不可能的，只有一个是可能的。

　　那再看D，在1990年中雨天数比1910少的情况下，其降雨量可以超过1910的2倍吗?绝不可能 ------ 因为2>=moderate rainfall > 1，即最大的中雨量不超过最小的中雨量的2倍，也就是：即便1990的中雨天每次都是最大量，而1910的中雨量每次都是最小量，那么D都不能成立。

而B与C明显与已知条件矛盾(“1990年小雨和中雨的天数都比1910少”)

　　而E与“1990年全年的降雨量还比1910多”冲突

　　看来也就A有希望了;但A与我们的预估相反。

　　但从问题中的“helps to account for”可以明确该题是解释题，所以要怀着读出“奇怪或矛盾”的目的去阅读原文(绝不是怀着奇怪的心态去阅读)

　　读完原文发现，一方面vacationer占了参观pure aquariums人数的一半，而同时只占了参观zoo人数的不到四分之一。这是怎么回事呢?尤其是zoo中还有zoo aquarium呢。这题读完，本身觉得也没啥矛盾，就是心里觉得怪怪的。(注意原文中account for 意为“占”，而问题中的意为“解释”)

　　初步预估，大概是vacationers都是纯爷们，特爱看纯水族，不是很爱看ZOO中的水族(毕竟scope不如纯的全面)

　　如果这样想，很多人就会青睐D项;D说人民群众参观ZOO的可能性是参观纯水族的两倍多，好像解释了;仔细一想不对啊，这和vacationer占参观人数的比例毫无关系啊;同学们，分子分母思维法，不可只想分子，更不可只想分母啊。
