Question

Dr Crock's claims  have been not corroborated  by other scientists or published in a prestigious journal but have nonetheless garnered a great deal of attention from the public

There is an error with parallelism in the above sentence. Can someone please help me with this?

ANSWER: Dr Crock’s claims have not BEEN corroborated by other scientists or PUBLISHED in a prestigious journal but HAVE nonetheless GARNERED a 
 great deal of attention from the public.
This is a problem from MGMAT.(parallelism chapter question nos:15)

Hello,  dharun08 . The problem in the original sentence appears to be the placement of the word  not . It is customary in English to place the negation between the two halves of a verb written in the present perfect or past perfect tense.

1) I  have been  studying.
1.2) I  have  not  been  studying.

2) She  had won  the Nobel Prize.
2.2. She  had  not  won  the Nobel Prize.

If you look at the sentence you reproduced earlier, you can check for parallelism by carrying over  Dr. Crock's claims  into both halves of the sentence:

Dr Crock's claims  have  not  been   corroborated   by other scientists  or  published  in a prestigious journal  BUT
    have   nonetheless   garnered  a great deal of attention  from the public

The placement of  by other scientists  and  from the public  is a little different because that is simply what the context of each part of the sentence dictates. It would not make sense in the second part to write,    have nonetheless garnered  from the public  a great deal of attention.  That is just the way this particular sentence takes shape.

I would suggest you read the chapter very carefully, taking notes when you need to, and taking breaks if necessary, so that you can process all the information. Parallelism is important to understand for GMAT™ purposes.

Good luck with your studies.

I still confused about this answer. I couldn't see the parallelism of "not"..."but"... after correcting

The sentence doesn't use "not" and "but" together in a correlative structure. So, it doesn't have the type of parallel structure you're thinking of.

Rather, it works this way:

Dr Crock's claims  have not x BUT have y

Dr Crock's claims  have not x BUT  Dr Crock's claims  have y.
