SC|GMAT prep| global economy

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

I chose C because of the comparison of the economy that exists between the 2 different time lines. Since this is wrong reason to choose C, I want to know how to solve such comparison based problems.
