Fill in the blank with the appropriate question tag:
The farmers have to wait for the rain to sow the paddy, ________?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → don’t they
Question tag after “have to”:
“Have to” means “must”. Here “have” is a main verb, not a helping verb. So the tag uses “do”, not “have”. The sentence is positive, so the tag is negative: “don’t”. “The farmers” becomes “they”.
Complete sentence: The farmers have to wait for the rain to sow the paddy, don’t they?
Why the Other Options are Incorrect?
Option 1: haven’t they — Incorrect. “Haven’t” goes with “have” as a helping verb. It comes before a past participle (V3) like “finished”. Example: The workers have finished the boundary wall, haven’t they?
Option 2: didn’t they — Incorrect. “Didn’t” goes with the past form “had to”. Example: They had to walk home in the rain, didn’t they?
Option 4: do they — Incorrect. This is a positive tag. It goes with a negative sentence. Example: The students don’t have to wear ties on Saturday, do they?
