I don't know that, either, but I happen to know that the island is separated into the Republic of Ireland and Northern Ireland, which belongs to the UK.
in school i learned that  Politically, Ireland is divided between the Republic of Ireland (officially named Ireland), which covers five-sixths of the island
I have never been to Ireland before. Oh, the island in the North Atlantic? That's interesting. Is Ireland part of the UK? It's beyond me, but Great Britain sits to its east, across the North Channel. I see. That is interesting. When was Ireland founded? I couldn't say, but I know it's Europe's third largest island. I had no idea. Do you know the population?
Politically, Ireland is divided between the Republic of Ireland (officially named Ireland), which covers five-sixths of the island, and Northern Ireland, which is part of the United Kingdom, in the northeast of the island.
