Setting up a corporation requires more paperwork and legal provision

lets draw an analogy :

Keeping aside all grammar : what will u put in the blank, taking cues from one's daily usage and sheer logic

Getting a 50 in Verbal requires more hardwork THAN...........................

A : To get a 50 in Quant
B : What it takes to get a 50 in Quant
C : To get a 50 in Quant
D : Getting a 50 in Quant
E : Getting a 50 in Quant

Guess B is an outwright NO ; AC AND DE are close contenders

Bxn AC & DE :

AC : Getting a 50........... THAN........To get a 50 : Parallelism broken

DE : Getting a 50.............THAN.........Getting a 50 : Parallelism Intact

Thus DE Wins , Now bxn D & E ( lets get back to the original Q )

The intent : Doing A requires more work than doing B or doing C and not that doing A requires more work than doing B and C

E : Setting up a Corp............THAN.........Establishing X and Y == Eliminated

D : Setting up a Corp.............THAN........Establishing either X or Y ==Perfect

Leading to D , my take.

parallel between the first and second phrase.
1st error:
'Setting up' should be paralleled to 'establishing' -> elliminate A, B, C
2nd error:
'a corporation' should be paralleled to either 'a proprietorship' or 'a partnership'. All are singular.
Therefore, D is the correct answer

6. Setting up a corporation requires more paperwork and legal provision than to establish
either a proprietorship or a partnership.

(D) than establishing either a proprietorship or a partnership
(E) than establishing proprietorships and partnerships

Please explain the reason to prefer one over other. Both the options look correct to me...Thank!

this is because of singular vs plural usage in un-underlined part.

comparing the paperwork required to setup 1 corporation to multiple proprietorships and partnerships. This sounds illogical to me.

d for me too,
reason:
1) the and makes the second part plural, single things cannot be compared to plural stuff.
2)plain old parallelism ---a company, a proprietorship, a partnership

In comparisons, it is not necessary to compare a singular to singular only.
IMO-
Ram is better than any other student in the class - singular- singular - correct
Ram is better than all other students in the class - singular - plural - correct

Although, I agree that there is a meaning difference in the above two.

KAPLAN OFFICIAL EXPLANATION:

“Than” must compare grammatically similar terms: cooking chickens is different than cooking eggs, not cooking chickens is different than eggs. Since “setting” is not underlined, you’ll have to make the underlined portion agree with it. So let’s look for an “-ing”form. That narrows it down to (D) and (E) “Corporation” is singular, so we have to compare it to singular nouns:a proprietorship or a partnership,in (D).
