Lets do it together.
A)
Since digital recording offers essentially perfect reproduction-on compact discs, digital audiotapes, or digital videodiscs-audiophiles can accumulate vast collections of music,
transferring them from one format to another, copying it, and digitally altering it with little effort and not damaging the sound quality.
There is a fact cited as a reason (usage of
since to indicate causation)[ please refer to
initial dependent clause].
And that reason opens up a possibility for audiophiles [refer to
main clause/independent clause].
And then are cited 3 ways in which audiophiles can actualize that possibility [ refer to
3 adverbial modifiers modifying the preceding clause or main clause].
audiophiles can accumulate vast collections of music
How?
by
-->transferring them from one format to another,
-->copying it, and
-->digitally altering it with little effort and not damaging the sound quality.
Now ask yourself:
Is it
music which can be transferred from one
format to another
format
or
Is it
collections of music that can be transferred from one
format to another
format
OR,
you can also ask:
Is it
music which is in formats--digital format or analog format.
or
Is it
collections of music which is in formats--digital format or analog format.
It is music that is transferred from one format to another( digital to analog or analog to digital ).
That is,
You transfer music.
You accumulate collections-- collections of music, collections of stamps etc.
Therefore,
them in option A is problematic.
(A) music, transferring them from one format to another, copying it, and digitally altering it with little effort and not damaging
Further note that
demaging is not parallel with anything.
(A) music, transferring them from one format to another, copying it, and digitally altering it with little effort and not damaging
Let's delve a little further into this one ( just for the sake of fun).
Focus on the bolded parts:
(A) music, transferring them from one format to another, copying it, and digitally altering it with little effort and not damaging
with little effort is a prep phrase.
A prep phrase can function either as an adjective OR as an adverb.
with little effort modifies
altering.
with little effort, therefore, functions NOT as an adjective BUT as an adverb.
Further
with little effort is followed by
and--a parallel marker.
What it means is that what appears on LHS of
and MUST be parallel with what appears on RHS of
and.
(A) music, transferring them from one format to another, copying it, and digitally altering it with little effort and not damaging
with little X and no Y.
X and Y should have been parallel.
Have a look at other answer choices to see whether there exists any other choice with this issue and what are the alternates available.
There are two reasons we do this verticle scanning:
1) GMAC deploys what we in tutoring community call 3/2 split, one of the favorite tools of GMAC.
2) In GMAT SC, you NEVER NEVER, NEVER EVER, EVER EVER analyze answer choices ABSOLUTELY. You always analyze answer choices RELATIVELY.
Now because GMAC knows that you will resort to 3/2 split analysis and RELATIVE vs ABSOLUTE analysis, it oftentimes places distractions so that you waste precious
seconds on issues that don't matter in GMAT SC.
Therefore, please keep in mind that NOT ALL 3/2 splits are genuine.
At times, there are also fake splits, which should never let you distract from other glaring errors in incorrect answer choices.
( Like everything else in GMAT SC, you get better at it ONLY with practice).
Coming back to the point of verticle scanning we were discussing:
Since digital recording offers essentially perfect reproduction-on compact discs, digital audiotapes, or digital videodiscs-audiophiles can accumulate vast collections of music, transferring them from one format to another, copying it, and digitally altering it with little effort and not damaging the sound quality.

(B) music, transferring it from one format to another, copying it, and digitally altering it with little effort and no damage to
(C) music, transferring them from one format to another, copy them, and digitally alter them with little effort and no damage to
(D) music and transfer it from one format to another, copy it, and then digitally altering it with little effort and not damaging
(E) music and transfer it from one format to another, copying it, and digitally alter it with little effort and no damage to
Parallelism is between noun and noun.
with little X
and no Y, where X and Y are nouns, and
little and
no are adjectives modifying
effort and
damage respectively.
How much effort?
little effort.
How much damage?
no damage.
A and D lack parallelism.
Eliminate them.
Here are the other 3/2 splits that we have identified in this SC:
-->them vs it

No issue with
structual parallelism in D and E.
Faulty logical parallelism is at play, however.
Again RELATIVE REASONING is the key to identify all logical errors( errors that pertain to
meaning as opposed to
grammar), such as faulty logical parallelism.
There are also other errors in C, D, and E.
And that is for you to figure out.
