summary:
C is the best.
- 'but that' is correct for parallelism.

None of the answer choices are perfect:

A. "Preceded with" is wrong. Should be "preceded by"
"was or was not" unidiomatic, wordy and awkward.
B. "Whether or not" is redundant and hence wrong on the GMAT. Whether should suffice.
"For determining" is wrong. It should be "to determine"
C. The use of "that" is avoidable but doesnt make the construction wrong. the best among the given options
D. "Preceded with" is wrong. Should be "preceded by"
E. "For determining" is wrong. It should be "to determine"
"is or is not" unidiomatic, wordy and awkward.

A. wrong construction 'was or was not'. Wrong time ('is' required)
B. 'whether or not' - right construction. 'Was' changed to 'is'. Than correctly terminated by 'is'. Right one - correct answer
C-E. 'but that' is awkward and ungrammatical.

What is OA?

Re: Researchers [#permalink] New post 29 Jul 2009, 00:10
IMO C.

The sentence is using the structure X but Y, we need to maintain parallelism between X and Y.
Here to maintain parallelism, we need to have a "that" after "but"
Researchers agreed that the study......but that more research....

Re: Researchers [#permalink] New post 29 Jul 2009, 00:11
I am not fan of 'whether or not', 'whether' is sufficient.

IMO:

- agreed that .. , but that -> shows parallelism.
Can someone confirm?

- Also in B 'is' is not necessary in end.
Is it?

I pick C.

Just a little query!! :)

The whole sentence is of past tense.

Why we are using "is" in below phrase
balloon angioplasty preceded by ultrasound is any better for heart attack patients ..

Why not "was"???

I derived the same answer, so I definitely think it's correct.

We already started new clause with conjunction 'but', so 'that' is absolutely redundant here!

Reseach was conducted in the past, but 'balloon angioplasty preceded by ultrasound' is better in the past and present.

Past: balloon angioplasty was better (until sth. new is invented)
Present: balloon angioplasty is better (still nothing is better)

what about the clauses when we use it with the conjunction 'and'? In that case, we look for parallelism "and that". Why in that case 'that' is not redundant?

IMO:
In D, "determined that" makes it in a subjunctive mood, so usage of 'was' is not correct.

Answer: C



Hi Mbaiseasy

I have a small doubt could you please explain why is it needed for rather than needed to ?

ex : I needed to go the marriage . -- > i must go to the marriage . -- compulsory
I am needed for attending the marriage --> here it is not compulsory , probably no one can drive the car so someone needs me to drive the car for attending the marriage .

I used this logic and picked up B . Why is needed for determing wrong ?

hi,

in GMAT you will not find sentences like this:
he was confused whether or not he should go.......>>>>if you encounter this just neglect that option

but yes if you get sentence like this:
I have not decided whether I should wear black or white dress tonight.====>this is correct

so whether or not is wrong....rather choose option which has only WHETHER in it...

hope it helps
