34: GWD-18-Q31
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

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

正确是A。
虽然讨论过，我也清楚了B,C,D,E为什么错。  唯一不明白的就是A中it指代global economy。不是说it指一样的东西，不一样的要用that什么来指代么？要是此处it指了global economy，不会造成it指了1990-2000的global economy的歧义么？
希望NN指教！

Between 1990 and 2000 在A和在E中是不同的用法   在A中作状语，在E中作定语。因此在E中it指代的内容包括其定语Between 1990 and 2000，而A中不是。

可是，我想知道此句中it的知道问题。不是说 it, they 指代句子前面出现过事物，精确指代前文出现的该特定事物，该事物的修饰成分，特性均被继承在it, they当中。这一题A选项 it指了global economy，不会造成it指了1990-2000的global economy的歧义么？
