Sentence Correction

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

My analysis:

A team of scientists found ..............that is logical in this context.

This kills A, C, and E.

In the option D.

By recording ................., the sound emissions--It seems that the sound emissions are doing the task of recording, making the intended meaning altered.

This kills D.

Answer is B.

Is there any other explanation about D?

Thanks.

Your analysis is absolutely correct. I have something to add..

The team of scientists is making the discovery of Noise. How are they doing so? The answer is "By digitizing and ...". This makes B correct.

If you see D "the sound emissions were digitized and analyzed on computers" ...ok they are digitized and analyzed. But who did that? Did the team use that analysis? These two questions answer D fails to answer.

That was exactly the issue -- a modification mismatch. The emissions cannot do any recording.
