hi, friends! I was confused during my lesson today. I need some help about question tags.
1)Mary is in London now, isn �t she? according to this sentence , if we want to give a short answer what shall we say? In my opinion the short answer must be "Yes, she is." In my teacher �s book there is sth. wrong with the answers I think. I am confused !!!Could you please control my short answers?
1)A: Mary is in London, isn �t she?
B: Yes, she is.
2) A: Ankara is the capital city of Turkey, isn �t it?
B: Yes, it is.
3) A: Serkan �s best school subject isn �t Maths, is it?
B: No, it isn �t.
4) A: He isn �t going to visit Anıtkabir tomorrow, is he?
B: No he isn �t.
5) A:They are going to visit Anatolian Civilization Museum, aren �t they?
B:Yes, they are.
6) A:They aren �t going to have lunch at home, are they?
B:No, they aren �t.
are these right or not?While giving short answers to the sentence with a tag question, we are looking the main clause?If the main clause is affirmative, we give a positive answer?if the main clause negative, we give a negative short answer?
heeeellllppppp!!!!what is the rule?
