Sentence Correction: Concise vs. Short & Redundant vs. Long

Drums are not only musical instruments but also play an integral part in the spirituality of many cultures around the world.

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 noun instruments. But also, however, is followed by the verb play.

What helps us identify this question as a Parallelism question as well as identify the mistake is the following Stop Sign:

not only... but also...

This answer choice repeats the original Parallelism error. But also must be preceded by not only.

What helps us identify this question as a Parallelism question as well as identify the mistake is the following Stop Sign:

not only... but also...

This answer choice repeats the original Parallelism error. Not only must be followed by but also, not but in fact.

What helps us identify this question as a Parallelism question as well as identify the mistake is the following Stop Sign:

not only... but also...

Although this answer choice corrects the original Parallelism error by placing a noun after but also, it changes the meaning of the original sentence by removing the phrase of the spirituality. This phrase tells us what part of the culture is influenced by the drums.

Do not automatically choose the shortest answer choice. Make sure that shorter answers express the same meaning that's been stated in the original sentence. If they don't, they're probably incorrect.

Nicely done!

In the original sentence, a noun (instruments) follows not only whereas a verb (play) follows but also. This creates a Parallelism error. This answer choice corrects the error by placing a noun (part) after but also.
