GMAT Paper 30

Q29:
Researchers agreed that the study of new treatments for heart attack patients was
extremely important but more research was needed to determine that balloon angioplasty
preceded with ultrasound was or was not any better for heart attack patients than the
balloon procedure by itself.
A. more research was needed to determine that balloon angioplasty preceded with
ultrasound was or was not any better for heart attack patients than
B. more research was needed for determining whether or not balloon angioplasty
preceded by ultrasound is any better for heart attack patients than is
C. that more research was needed to determine whether balloon angioplasty preceded
by ultrasound is any better for heart attack patients than
D. that more research was needed to determine that balloon angioplasty preceded
with ultrasound was any better for heart attack patients than
E. that more research was needed for determining that balloon angioplasty preceded
by ultrasound is or is not any better for heart attack patients than is

Ans given is B. I think it is D. Am I Right ?

[dbernst]

The first "split" I noticed was "preceded by" v. "preceded with." As one thing is preceded by another, eliminate choices A and D. The second "split" I noticed was "needed for determining" v. "needed to determine." Idiomatically, needed to determine is correct. Eliminate B and E. The best answer is C.

ps. A third "split" that could have guided your process of eliminate was the "more research" v. "that more research." Since the non-underlined portion of the sentence states "researchers agreed that," a second "that" is needed to maintain proper parallelism.

[Samy]

Actually I had marked C. That D was a misprint.
But as usual due to the ans mentioned I was in a dilemma.
I first noticed the "that", then went on to the idioms.

Thanks. The clarity and approach you provided helped a lot.

Lets say we also have choice F

F. that more research was needed to determine whether balloon angioplasty preceded
by ultrasound is any better for heart attack patients than IS


basically

X is any better than Y

or

X is any better than is Y

or

X is any better than Y is


which one is correct...

Please help...

Thanks
