Choose the correct question tag to complete the sentence:
Your grandparents grow their own vegetables in the backyard, ________?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → don’t they
Question tag after a simple present verb with a plural subject:
“Grow” is in the simple present and has no helping verb. So the tag uses “do” or “does”. With a plural subject, the tag takes “do”. The sentence is positive, so the tag is negative. “Your grandparents” becomes “they”.
Complete sentence: Your grandparents grow their own vegetables in the backyard, don’t they?
Why the Other Options are Incorrect?
Option 1: aren’t they — Incorrect. “Aren’t they” goes with a sentence that has the helping verb “are”. Example: Your grandparents are visiting us this Pongal, aren’t they?
Option 2: doesn’t they — Incorrect. “Doesn’t” goes only with he, she or it. Example: Your grandfather grows chillies on the roof, doesn’t he?
Option 4: haven’t they — Incorrect. “Haven’t they” goes with a sentence that has the helping verb “have”. Example: Your grandparents have moved to Mysuru, haven’t they?
