GMATPrep - Parallelism,logic, modifier

by GMATMadeEasy » Sun Nov 14, 2010 4:16 am
By recording the noise of crinkled wrappers as they were slowly stretched out in an otherwise silent chamber, and then digitizing and analyzing the sound emissions on computers, a team of scientists found the noise not continuous but consisted of individual bursts or pops just thousandths of a second long.

(A) digitizing and analyzing the sound emissions on computers, a team of scientists found the noise not
(B) digitizing and analyzing the sound emissions on computers, a team of scientists found that the noise was not
(C) digitizing and analyzing the sound emissions on computers, a team of scientists found the noise not to be
(D) the sound emissions were digitized and analyzed on computers, a team of scientists found that the noise was not
(E) the sound emissions were digitized and analyzed on computers, a team of scientists found the noise not to be

How to choose between A, B and C ?

IMO B

Among A,B, and C only B contains the verb WAS. Noise was not continuous.... Noise was consisted of X. IMO Verb is required for both the parts of the sentences.

Also "found that" seems correct usage.
If the problem is Easy Respect it, if the problem is tough Attack it

(C) digitizing and analyzing the sound emissions on computers, a team of scientists found the noise not to be
Following the same reasoing C is also correct. that is (ignoring the error of "that") :

noise not to be continuous but to be consisted of .

is it correct in that case ?

I think it violates parallelism. to be is required after but.

I believe that, with the omission of "that", (a) and (c) can be read as if a seemingly imperceptible noise was found (i.e. identified) by a team of scientists. (b) is different because it refers to a characteristic of the noise itself. These are two different meanings, and I think (b) better captures the intended meaning, given the rest of the sentence.

I'm really old, but I'll never be too old to become more educated.
