Grammar Agreement Questions Medium
The rule for agreement with tag questions is that the verb in the tag question should agree with the subject of the main sentence. If the main sentence has a positive verb, the tag question should have a negative verb, and vice versa. Additionally, if the main sentence is in the present tense, the tag question should also be in the present tense. If the main sentence is in the past tense, the tag question should be in the past tense as well.
