Each question is divided into four parts where one of the parts may or may not contain an error. Choose the part that has the error as your answer. If all the parts are correct choose “No Error”.

Sarah is considered one of (A)/ the top researcher in the field (B)/ of neuroscience due to (C)/ her groundbreaking discoveries. (D)

The correct answer is B.

Step-by-step Explanation:

1. Grammar Rule: The grammatical structure "one of the..." is used to refer to a single item or person out of a group. Because it refers to one member among several, it must always be followed by a plural noun (or plural noun phrase).

2. Sentence Analysis:

• Part (A): "Sarah is considered one of" - This introduces the phrase requiring a plural noun after "the".

• Part (B): "the top researcher in the field" - Here, the singular noun "researcher" is used instead of the plural form "researchers".

• Part (C): "of neuroscience due to" - Correct prepositional usage and reasoning.

• Part (D): "her groundbreaking discoveries." - Correct noun phrase.

3. Correction: The singular noun "researcher" in part (B) should be replaced with the plural noun "researchers".

Corrected Sentence: "Sarah is considered one of the top researchers in the field of neuroscience due to her groundbreaking discoveries."

Therefore, part (B) contains the error.
