31. Statistics indicate that approximate every 22 years--within a range of 3 to 4 years--a major drought occurs in the United States.

答案有的选A有的选B，到底是哪个？我觉得两个都错

39. By 1810 the 23 towns of Hampshire County, Massachusetts, had reached a remarkable uniform of economic development as well as population density.

选C还是D?
as well as 和 and 在用法上有区别吗？
by 后面跟时间怎么解释？是什么用法？

31   B改为approximately
39   as well as不能连接谓语，and可以
      by+年，表示截止到某年，完成时的标志

Statistics是统计学的意思，谓语动词应该用单数吧．我觉得把indicate改成indicates．

statistics 还有一个是统计数据的意思，是复数。我觉得在这题中作数据解释比作统计学解释要好。

statistics可以看作单复
同行吧

字典上说statistics没有单数含义，所以就不要看作单数或单复同形，以后一律理解为复数就行了。
