The following sentence has been split into four segments. Identify the segment that contains a grammatical error.
My sister Mona / never drinks coffee; / she prefer tea / in the morning.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. she prefer tea.
Error concept: Subject–Verb Agreement
What is wrong: The verb “prefer” is used in its base form, which is incorrect with the singular subject she.
Grammatical concept: With third person singular subjects (he, she, it, singular nouns), we use the verb with –s / –es in the Simple Present Tense.
Incorrectness of the concept in context: The subject is she (singular), so the verb must be prefers, not prefer.
How to correct: Replace prefer with prefers.
Correct phrase/ correction: she prefers tea
Final sentence: My sister Mona never drinks coffee; she prefers tea in the morning.
Hence, the chosen option is correct.
