Input: Question: Is the place composed of one large island and several smaller island chains an independent country? Passage:A distinction is often made between the island of New Guinea and what is known as Island Melanesia, which consists of "the chain of archipelagos, islands, atolls, and reefs forming the outer bounds of the sheltered oval-shaped coral sea". This includes the Louisiade archipelago (part of Papua New Guinea), the Bismarck Archipelago (part of Papua New Guinea and Solomon Islands), and the Santa Cruz Islands (part of the country called Solomon Islands). The country of Vanuatu is composed of the New Hebrides island chain (and in the past 'New Hebrides' has also been the name of the political unit located on the islands). New Caledonia is composed of one large island and several smaller chains, including the Loyalty Islands. The nation of Fiji is composed of two main islands, Viti Levu and Vanua Levu, and smaller islands, including the Lau Islands.
