South Korea and Japan, which have the two most robust capitalist econ

It doesn't help, how both could be with as weel as?

I do not see "and" for "both" in choice B. pls, show it to me? thanks

Hi Experts,

Can you please explain why option B is correct for this instead of option A?
"Both" is followed by and in option A, which I believe is the correct usage.

Hi @E-GMAT,
Can you please solve this one?

Anyone please confirm about ....presence of "both ....and" in the sentence.

Also in "D" if instead of successes we have "success" dr than it would be correct or not?

A is wrong because phases after both should be equal .
Idiom is both "A" and "B".
In option A "both companies that are newer and smaller" , correct form should have been companies that are both newer and smaller

Both X as well as Y is unidiomatic.

See, for example, Official Guide 2018 SC #681, which you can find here

That unidiomatic expression shows up in every single answer.

I tried to work with what was left.

None of the answer choices is correct.

B is not parallel.

SajjadAhmad , this question just does not work.
Both . . . . as well as is wrong.

Split #1:
A and C incorrectly insert THEY into a compound predicate

(compound predicate means that the sentence contains
compound verbs = two or more verbs that point to one subject)

If we have a compound predicate?
We do not use a comma. AND we do not repeat the subject in the second predicate.
We should not insert a pronoun in the second predicate.

Correct: Anne and Kim walked to the gym and worked out for an hour.
Wrong: Anne and Kim walked to the gym and they worked out for an hour.

Eliminate A and C

Split #2: confusion
In option D, does BOTH mean that there are TWO smaller, new companies?
Or does BOTH refer to smaller, newer companies AND large conglomerates.

Eliminate D

Split #3: lack of parallelism

B incorrectly puts SUCCESS before BOTH

No parallelism in B

South Korea and Japan . . . now take an active role in the success both of newer, smaller companies as well as that of
Parallelism?

ACTIVE ROLE IN:

the success
BOTH
of smaller, newer companies
AS WELL AS
that of
large conglomerates

IN the success BOTH of X as well as [that of] Y?
No.

Not parallel.
BOTH ruins the parallelism.

I think that this OE is wrong.
See the correct sentence in green typeface, below.

Lack of parallelism in E
E. role now in both the success of newer, smaller companies as well as [that of

role now in
BOTH
the success of newer, smaller companies
AS WELL AS
larger conglomerates

What happened to the success of?
Option E needs to include THAT OF as indicated.
Not parallel.

Conclusion: no answer is correct.

We do have a takeaway:
BOTH and AS WELL AS should not be in the same sentence.

Finding SC questions to post is incredibly difficult.
I would know.
I and two colleagues just posted 288 SC questions in Project SC Butler, here

Occasionally we will find a poor quality example.

This phrasing is parallel:
South Korea and Japan . . . now take an active role BOTH in the success of newer, smaller companies and in THAT OF larger conglomerates.

South Korea and Japan . . . now take an active role in the success of newer, smaller companies AS WELL AS in THAT OF larger conglomerates. [no BOTH]

No such option exists.

I am going to archive this question.

All, I hope that analysis helps.
