Choose the most suitable option to replace the highlighted part of the sentence: She has a car, isn't it?'
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. doesn't she?.
Error Concept: Tag doesn't agree in auxiliary verb and subject.
What is wrong: 'isn't it?' is incorrect because the main verb 'has' (indicating possession) requires the auxiliary verb 'do/does' for the question tag in the Simple Present Tense.
Grammatical Concept: If the main clause is positive, the tag must be negative. When the main verb is a form of 'has' (possession), we use the auxiliary 'does' for singular subjects.
Incorrectness of the concept in context: Using 'isn't it?' implies a state of being (verb 'to be'), which violates the rule of repeating the auxiliary implied by the main verb 'has'.
Correction: Since the subject 'She' is singular and the sentence is positive, use the negative auxiliary 'doesn't she?'
Correct phrase: doesn't she?
Final sentence: She has a car, doesn't she?
Hence, the chosen option is correct.
