Identify the grammatical error in the sentence below.
We don't have to go to the party, don't we? We can stay at home.
Show answer & explanation
Correct answer: A
Explanation
Correct Answer: don't we
Explanation
• The error lies in the question tag don't we.
• According to question tag rules, a negative statement is followed by a positive question tag, whereas a positive statement takes a negative tag.
• The main clause "We don't have to go to the party" is negative (uses don't), so the tag must be positive: do we?
• Correct sentence: We don't have to go to the party, do we? We can stay at home.
