GMAtPrep - Comparison (verb tense)

by GMATMadeEasy » Tue Jul 05, 2011 4:31 am
Since 1990 the global economy has grown more than it did during the 10000 years from the beginning of agriculture to 1950.
A. Since 1990 the global economy has grown more than it did during the 10000 years from the beginning of agriculture
B. Since 1990 the growth of global economy has been more than that during 10000 years, from when agriculture began
C. The growth of the global economy since 1990 exceeds that which had been for 10000 years from the beginning of agriculture.
D. The growth of the global economy since 1990 exceeds what it has been for 10000 years, from when agriculture began
E. The growth of the global economy since 1990 exceeds what it did for the 10000 years from the beginning of agriculture.

I have issue understanding A how come "the global economy has grown" and "it did" can be used ? it should be "it did grow ". If first part had a verb as do grow, or grow/grows, it could be okay.

Could you explain please, looks, there is something wrong in my way here.

GMAT-Prep SC: Final solution at one place:

Important: The purpose of this post (and all the other posts by me) is to give a complete solution to all GMAT-Prep Verbal questions at one place. Sometimes students have to wade through dozens of posts to get to the final answer. My posts will give one complete and crisp solution required to arrive at the correct answer by eliminating the wrong ones. Some of the content in these posts may have been taken from various other sources (discussion forums).

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

This question can be very easily answered by VAN ... Verb > Adjective > Noun ... verb forms are preferred to the adjective forms; the adjective forms are preferred to the noun forms.

Choice A has 'has grown (verb form)'. All the other choices have 'growth (noun form). So A has to be correct provided there are no other errors in A.

A. 'Since 1990' definitely mandates present perfect tense, so 'has grown' is correct. 'Has grown more than it (the global economy) did (grew)' ... this shows proper parallelism and comparison.

We have to be specific as to 'which 10000 years?' The use of the word 'the' is correct here. It shows a specific period with a starting point (the beginning of agriculture ... this is a noun ... exact point in time when agriculture started) and an end point (1950).

So choice A has no grammatical errors. CORRECT.

B: the word 'the' is missing ... WRONG
C: 'that which' ... wrong; 'had been (past perfect tense)' ... wrong as there is only one past action.
D: 'has been' is definitely wrong as we are referring only up to 1950, not till now.
E: The growth of the global economy since 1990 exceeds what it (the growth) did ... wrong meaning. The 'growth' didn't do anything.
Also, the word 'exceeds' is definitely wrong in such a construction (C, D, and E eliminated).

Another similar question from GMAT-Prep:

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

Correct answer: A (refer to the explanation above).
