Identify the part containing a grammatical or structural error:
The behaviour of these students leave much to be desired.
Show answer & explanation
Correct answer: A
Explanation
Subject-Verb Agreement: The subject of the sentence is "The behaviour," which is a singular noun.
Verb Conjugation: In English, a singular subject requires a singular verb. The plural verb "leave" should be changed to the singular form "leaves."
Distractor: The plural noun "students" is part of a prepositional phrase ("of these students") and does not determine the verb form.
Correct Sentence: The behaviour of these students leaves much to be desired.
