However much united states voters may agree that
there is waste in government and that the government as a whole spends beyond its means, it is difficult to find broad support for a movement toward a minimal state.
IMO the correct answer is 'A'. Following is the explanation:
Firstly, the sentence demands a contrast in the 2 parts separated by commas.
Thus, E is out because it is more of a run on sentence. There is no contrast.
Secondly, in the question we are trying to make a statement 'there is waste in gvt.....' which has to be preceded with a 'that'.
Only option A & E have 'that' in the end, and 'E' is already out. So answer is A, although i am not very convinced with the way option A starts.
A. However much united states voters may agree that
B. Despite the agreement among united states voters to the fact
C. Although united states voters agree
D. Even though united states voters may agree
E. There is agreement among united states voters that
Hope it helps.
