Sentence Correction: Pronoun Questions - One

By employing workers for the right positions and at the appropriate stage, one can accelerate the growth of one's small business as more time will be available for important decisions, creating partnerships, and planning campaigns.

This answer choice commits a Parallelism error and is grammatically incorrect. The last two items in the list at the end of the sentence are unconjugated verbs (creating, planning), but the first item is a noun (important decisions). The items must be of the same part of speech.

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

A list of 3 items or more, separated by commas and and/or before the last item.

Although this answer choice corrects the original Parallelism error by placing three verbs in the list at the end of the sentence, it is not the most concise of the grammatically correct answer choices.

Although this answer choice corrects the original Parallelism error by placing three verbs in the list at the end of the sentence, it creates a Pronoun error. The pronoun their refers to one but does not agree with it as one is singular and their is plural.

The pronoun one agrees with itself only.

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

Every pronoun in the underlined part of the sentence or after it

Although this answer choice corrects the original Parallelism error by placing three verbs in the list at the end of the sentence, it creates a Pronoun error. The pronoun his can refer to human male nouns, but there's no such noun in the sentence.

The pronoun one agrees with itself only.

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

Every pronoun in the underlined part of the sentence or after it
