Hi
RickooreoI went through your analysis.
You were able to identify successfully only one of the errors: "comma + that".
You need to work on Structural Analysis of Sentences, simply because
a. the subject of 'was' at the start of choices C and D is not 'views' but "
repertory, views, and vocal style"
b. the subject of the second 'was' in choice C is "Bill Monroe"; so, no, we do not need a subordinating conjunction before this 'was'.
You also need to work on identifying the antecedents of pronouns. You're right that 'who' refers to persons, but 'musicians' are persons, aren't they?
You can study the solution to this question in detail on its dedicated thread on GC. The reason I shared this question with you was to see if you can spot "
Wordiness" and "
Redundancy". However, you haven't spotted these errors in your analysis.
In the interest of saving time, allow me to point them out. You can observe these errors accordingly.
1. "
was influential to" and "
were an influence on" are wordier alternatives to "
influenced".
2. "
was inspirational to" and "
was an inspiration to" are wordier alternatives to "
inspired".
3. "
was different from" and "
was different in comparison to" are wordier alternatives to "
differed from".
4. "was different from
that of his own" in choice E is an example of redundancy. "
his own" already means "
Bill's own (music)". Hence, "
that of his own" would mean "
music of his own music".
I hope you now see how
Wordiness and
Redundancy are tested in GMAT SC.
Happy Learning!
