OFFICIAL EXPLANATION



Benefiting from the popularity of prior entertainment genres such as minstrelsy, animal shows, and magic acts, Vaudeville theater not only appealed to audiences of diverse gender and class backgrounds, but the widespread success it enjoyed in 19th and 20th century America is attributed to the incorporation of sophisticated financial management.

A) magic acts, Vaudeville theater not only appealed to audiences of diverse gender and class backgrounds, but the widespread success it enjoyed in 19th and 20th century America is attributed to the incorporation

Incorrect.

This answer choice is grammatically incorrect and illogical. In the GMAT, not only must normally be complemented by but also.

Stop Sign: not only A but also B

When you identify this structure, make sure it follows these rules:

1. Both not only and but also appear. Using only one is incorrect.
2. A and B (the items of the parallelism) are the same part of speech.
3. A and B are logically parallel.

But the problem here is one of Parallelism, which also makes this answer choice illogical. The connector but should be used to describe a contrast between two clauses or items. However, here but connects two clauses which both make similar positive statements about Vaudeville theater's appeal and success.

Look for another answer choice that constructs the parallelism logically.



B) magic acts, Vaudeville theater in 19th and 20th century America enjoyed widespread success not only due to its appeal to audiences of diverse gender and class backgrounds, but also due to the incorporation

This answer choice corrects the original Parallelism mistake in two ways:

1. It corrects the grammatical form by complementing not only with but also.

2. By changing but to but also, the corrected sentence fixes the sentence's logic (as but also does not imply a contrast between items). Both items in the parallelism are reasons for Vaudeville's success: not only due to A (its appeal) but also due to B (the incorporation, etc.).

Although the corrected sentence contains a stylistic flaw of ambiguity (its can refer to the 20th century or to America), it is the only answer choice that is both logical and grammatically correct.



C) magicians, the widespread success of Vaudeville theater in 19th and 20th century America is attributed not only to its appeal to audiences of diverse gender and class backgrounds, but also to the incorporation

Incorrect.

This answer choice corrects the original Parallelism mistake by complementing not only with but also. It also corrects the logical mistake in the original sentence, by constructing a logical parallelism of two reasons for the success of Vaudeville theater (attributed not only to A but also to B).

However, the corrected sentence creates a new Parallelism mistake by changing magic acts to magicians. Although magic acts and magicians are grammatically parallel (both are nouns), they are not logically parallel: a magic act is an example of an entertainment genre, while magicians is not.

Stop Sign: not only A but also B

When you identify this structure, make sure it follows these rules:

1. Both not only and but also appear. Using only one is incorrect.
2. A and B (the items of the parallelism) are the same part of speech.
3. A and B are logically parallel.

In addition, by changing the subject of the sentence from Vaudeville theater to the widespread success of Vaudeville theater, this answer choice creates a new logical mistake. The modifier Benefiting from...magic acts should logically modify Vaudeville theater, but it is followed by the widespread success.

What helps us identify this question as a **Dangling or Misplaced Modifier** question as well as identify the mistake is the following Stop Sign:

A modifier

  • Verb+ing or V3, or non participial phrase at the beginning of the sentence, and separated by a comma). The modifier should modify the noun following the comma.
  • Verb+ing or V3, or non participial phrase appearing in the middle to end of a sentence and preceded by a comma; the modifier should refer back to the nearest subject or clause or show the result of the previous clause.
  • Verb+ing or V3, or non participial phrase appearing in the middle to end of a sentence and NOT preceded by a comma; the modifier should modify the preceding noun or noun phrase.

Whenever you see this Stop Sign, focus on the modifier: check whether the modifier modifies what it is supposed to.



D) magical shows, Vaudeville theater not only appealed to audiences of diverse gender and class backgrounds, but also its widespread success in 19th and 20th century America is attributed to the incorporation

Incorrect.

This answer choice is grammatically incorrect. The same part of speech that follows not only must also follow but also. In this answer choice, not only is followed by the verb appealed. But also, however, is followed by by a noun phrase its widespread success.

Look for another answer choice that constructs the parallelism grammatically and logically.



E) magic acts, Vaudeville theater had widespread success not only because it appealed to audiences of diverse gender and class backgrounds, but also because it incorporated

Incorrect.

While this answer choice corrects the Parallelism mistake in the original sentence by complementing not only with but also, and creating a logical parallelism between the reasons for Vaudeville's success, it is grammatically incorrect and stylistically flawed.

By changing incorporation to incorporated, the corrected sentence does not fit into the original sentence - it is not grammatically correct to say because it incorporated of. In addition, the phrase Vaudeville theater had widespread success is awkward. The idiom enjoyed success is stylistically superior.

A) magic acts, Vaudeville theater not only appealed to audiences of diverse gender and class backgrounds, but the widespread success it enjoyed in 19th and 20th century America is attributed to the incorporation
The meaning isn't perfect therefore out

B) magic acts, Vaudeville theater in 19th and 20th century America enjoyed widespread success not only due to its appeal to audiences of diverse gender and class backgrounds, but also due to the incorporation
THe meaning is perfect , the success was not only because of it's appeal over different social background but also the sophisticated financial mangement therefore let us hang on to it

C) magicians, the widespread success of Vaudeville theater in 19th and 20th century America is attributed not only to its appeal to audiences of diverse gender and class backgrounds, but also to the incorporation
THe meaning is fine except for the fact that magicians are mentioned along the line of genre which is not required therefore out

D) magical shows, Vaudeville theater not only appealed to audiences of diverse gender and class backgrounds, but also its widespread success in 19th and 20th century America is attributed to the incorporation
Similar reasoning as A

E) magic acts, Vaudeville theater had widespread success not only because it appealed to audiences of diverse gender and class backgrounds, but also because it incorporated
Similar reasoning as A

THerefore IMO B
