Since 1990 the global economy has grown more than it did during the 10,000 years from the beginning of agriculture to 1950.
(A) Since 1990 the global economy has grown more than it did during the 10,000 years from the beginning of agriculture
(B) Since 1990 the growth of the global economy has been more than that during 10,000 years, from when agriculture began
(C) The growth of the global economy since 1990 exceeds that which had been for 10,000 years from the beginning of agriculture
(D) The growth of the global economy since 1990 exceeds what it has been for 10,000 years, from when agriculture began
(E) The growth of the global economy since 1990 exceeds what it did for the 10,000 years from the beginning of agriculture

这题的正选是A，可是A中has grown more这个说法不是很怪么，more后面应该要跟一个副词才对吧。

我选的是B, 因为我觉得growth has been more 还说得过去一点~~~~

麻烦NN么指教一下~~~~

B里面错在from when,when的用法是直接接在时间词后面。growth名词形式不够简洁。

more可以做形容词，可以的。
