Many countries have islands, some have one main island and a few small islands whether inhabited or not, some have one main island and one or two tiny islands, but there are some countries that have literally just one island to their name, or perhaps are made up entirely of just one island. Can you name them all?
We're looking for sea islands rather than river islands, or 'metaphorical islands' etc. The names of the islands are given.
For fun, one country is included that used to have an island, but the sea level dropped, re-connecting it to the coast.
This is based on my own research, if there are errors or other answers I've overlooked, tell me! ^_^
