1. It's my card, isn't it?
To form a tag question, we use the auxiliary verb in the opposite form and add pronoun at the end. Since the sentence is positive, the tag question is negative. Therefore, "isn't it" is used as the tag question.

2. You are thirteen, aren't you?
The auxiliary verb "are" is used to form the tag question. The sentence is positive, so the tag question is negative with "aren't you" at the end.

3. You aren't Oleg's cousin, are you?
The auxiliary verb "aren't" is used to form the tag question. The sentence is negative, so the tag question is positive with "are you" at the end.

4. Your sister is fourteen, isn't she?
The auxiliary verb "is" is used to form the tag question. The sentence is positive, so the tag question is negative with "isn't she" at the end.

5. Your sisters are in the room, aren't they?
The auxiliary verb "are" is used to form the tag question. The sentence is positive, so the tag question is negative with "aren't they" at the end.

6. Your sisters' room is on the ground floor, isn't it?
The auxiliary verb "is" is used to form the tag question. The sentence is positive, so the tag question is negative with "isn't it" at the end.

7. Your sisters have got a room, don't they?
The auxiliary verb "have" is used to form the tag question. The sentence is positive, so the tag question is negative with "don't they" at the end.

Please note that tag questions are used to confirm or seek confirmation about the information stated in the main sentence. The tag question should use the appropriate auxiliary verb and follow the correct positive or negative pattern based on the main sentence.
