Between 1990 and 2000 the global economy grew more than it did during the 10,000 years from the beginning of agriculture to 1950.

A. Between 1990 and 2000 the global economy grew more than it did during the 10,000 years from the beginning of agriculture

B. Between 1990 and 2000 the growth of the global economy was more than that during 10,000 years, from when agriculture began

C. The growth of the global economy between 1990 and 2000 exceeds that which had been for 10,000 years from the beginning of agriculture

D. The growth of the global economy between 1990 and 2000 exceeds what it has been for 10,000 years, from when agriculture began

E. The growth of the global economy between 1990 and 2000 exceeded what it did for the 10,000 years from the beginning of agriculture

A，是答案

OG反复强调it指代和和前面提到的是同一个东西。有个OG题目关于地震的的，特别说明一个地震不可能在东部发生又跑到西部去发生

这里的it会不会有同样的问题呢，1900-2000之间的economy 和  economy from the beginning of agriculture to 1950 是两个不同的东东吧。为什么还可以用it指代呢？是不是我太专牛角尖了

during the 10,000 years from the beginning of agriculture to 1950 是 修饰 the economy grew 这个句子的时间状语，而不是仅仅修饰the economy

谢谢LS，做状语，用了it后两个句子主语变仍然成同一个东东了。同一个东东不可能在"1990 and 2000"之间grow 又在"during the 10,000 years from the beginning of agriculture to 1950" grow
