Correct Answer: A
Explanation: “Since 1990 the global economy has grown more than it did …..”- “since” used in this sentence should follow the present perfect tense. Therefore, “has grown” is placed correctly in the sentence. Moreover, the subject “it” refers to the subject “global economy” and the verb “did” indicates the identical action done by the subject i.e “has grown”. Therefore, the statement is structurally parallel. Both the verb and pronoun are used in a clear way. Hence option A is correct. Let’s have a look at the other options.

Option B
“Since 1990 the growth of the global economy …., from when the agriculture began”- The statement does not maintain a parallel structure. The statement should use the correct idiom i.e from X to Y. However, here “from when the agriculture began” to “what?”- cannot be determined. Moreover, the use of the definite article “the” before “agriculture is irrelevant. It is required to note that a definite article should not be used when talking about general things. Therefore, option B is incorrect. 

Option C
“…. exceeds that which had been for 10,000 years from the beginning of agriculture...” – The use of “that which” seems awkward in the sentence. The statement also does not use the correct idiom “from X to Y”. Hence the option is incorrect.

Option D
“…. since 1990 exceeds what it has been for 10,000 years, from when agriculture began...” -The statement does not maintain proper tense. “Since” is always followed by the present perfect tense. However, here the verb “exceeds” is in simple present tense form. Moreover, the statement also does not use the correct idiom “from X to Y”. Hence, option D is incorrect and thereby gets eliminated.  

Option E
“... since 1990 exceeds what it did for the 10,000 years from the beginning of agriculture...”.- The statement does not maintain proper tense. The use of “since” with the simple present tense "exceeds" is incorrect. Moreover, the statement also does not use the correct time frame “from X to Y”. Hence, option E is incorrect and thereby gets eliminated.
