Identify the segment in the sentence which contains a grammatical error.
Our new secretary’s performance have been quite impressive.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. have been.
The segment in the sentence which contains a grammatical error is "have been." The subject "performance" is singular, so it should be paired with the singular verb "has been" instead of the plural "have been."
The correct sentence should read: "Our new secretary’s performance has been quite impressive."
