Hi! Though I got the correct answer, In E the growth exceeds what it(growth) did(exceeded) for the 10,000 years...... seems right to me. Only what seems a bit awkward as it has been used as a pronoun here. Is this the reason to eliminate E?
When
did stands in for an antecedent verb on the GMAT, the following conditions will generally be satisfied:
1. The sentence compares one complete clause to another, with the use of
than or
as2.
did serves as the main verb of the second complete clause
3. The two clauses are relatively parallel
OA:
Since 1990 the global economy has grown more than it did during the 10,000 years from the beginning of agriculture to 1950Here, all three conditions are satisfied.
Each colored portion constitutes a complete clause.
The two clauses are compared with the use of
than.
The two clauses are relatively parallel in that each is composed of a subject, a verb, and a time modifier.
As a result, it is crystal clear that
did is standing in for the simple past tense form of the antecedent verb
has grown.
Conveyed meaning:
Since 1990 the global economy has grown more than it GREW during the 10,000 years from the beginning of agriculture to 1950.E:
The growth of the global economy since 1990 exceeds what it did for the 10,000 years from the beginning of agriculture to 1950.Here, none of the three conditions is satisfied.
The portion in red is not a complete clause but serves as the DIRECT OBJECT of
exceeds.
The entirety of E constitutes one complete clause.
Because the three conditions are not satisfied, the meaning conveyed by
did is unclear.
Eliminate E.
