B-I have a question about tag question. How are the answers if you allow or don't allow with the following tag question:
I can go out, can't I?
Answer: Yes, you can. No, you can't.

C-Please tell me what the difference between ON THE SEA/RIVER and BY THE SEA/RIVER are.
Ex: My village is ON the sea.
On the sea(side)/on the river usually means beside the sea/river. This may cause confusion because a person who lives in a houseboat lives on the river. A person who works on a ship and has no other home lives on the sea. For clarity, I prefer by/beside the sea/river.
My village is BY the sea. (OK).
