Question

Add a suitable question tag. We could hardly understand what he explained, ______?

• A. couldn't we
• B. could we
• C. can we
• D. do we

Answer 1

Answer:

B. could we

• The main statement contains “hardly,” which has a negative meaning.

• When the statement is negative in meaning, the question tag should be positive.

• The auxiliary verb in the statement is “could,” so the tag also uses “could.”

• The subject “we” remains “we” in the question tag.

Why the others are incorrect:

• couldn't we ❌ → Negative tag is not suitable because “hardly” already gives the statement a negative meaning.

• could we ✅ → Correct positive tag.

• can we ❌ → The auxiliary should agree with “could.”

• do we ❌ → “Do” is not the auxiliary used in the main clause.
