I guess it should be 'B'

a) comparision is being done to the "now"
C, D and E, I feel that "would have" is the not the correct usage here

economical changes the meaning - B, C, E out

A -- after more than comparison error (apples and oranges) - tense is wrong

D - my choice.

I was questioning that also. So far, GMAT does seem to prefer economic over economical. Just as GMAT prefers, most of the time, 'whether' over 'if'.

D it is.

"Would have" is a past conditional auxiliary verb phrase.

The word "to develop" demands "would have"

So the choice A and B are gone.

"economic" is related to the economy, while "economical" refers to saving money. So E and C are out

So IMO the answer is D

What is the source and "OE"?
IMO "B". I disagree with the usage of "would".."will" fits in here. Grammar Gurus -can someone explain why " would.." is appropriate?
