Which of the following Islands is NOT located in the Caribbean Sea?

1. A

   Grenada

   Grenada is an independent island country in the eastern Caribbean (Lesser Antilles). It is in the Caribbean Sea, so it is not the odd one out. This option is a true Caribbean island.

2. B

   Montserrat

   Montserrat is a British Overseas Territory in the Leeward Islands of the Caribbean. It lies in the Caribbean Sea. It is not the island that fails the location test.

3. C

   Madeira

   (c) Official key: Madeira is a Portuguese archipelago in the North Atlantic, off northwest Africa, not in the Caribbean Sea. Grenada, Montserrat and Anguilla are Caribbean (Lesser Antilles) islands. Madeira is therefore the island that is not located in the Caribbean.

4. D

   Anguilla

   Anguilla is a British Overseas Territory in the northern Lesser Antilles, in the Caribbean. It belongs with Grenada and Montserrat, not with Atlantic Madeira.

Summary. Official key is (c). Madeira sits in the Atlantic as a Portuguese island group; it is not a Caribbean island. Grenada, Montserrat and Anguilla are all in the Caribbean Lesser Antilles. The question asks which island is not in the Caribbean Sea. The keyed answer is Madeira.
