Answer:
The Bismarck Archipelago is made up of the eastern islands of Papua New Guinea.
Step-by-step explanation:
Papua New Guinea is a country comprised of roughly half of the New Guinea island and numerous islands around it. The biggest of these smaller islands is part of the Bismarck Archipelago, and this archipelago actually makes up a significant percentage of the total territory of the country.
While there are hundreds of islands comprising the Bismarck Archipelago, two of them stick out, New Britain (being the biggest) and New Ireland (the second biggest). These two islands of the arhcipelago are the most important for the country as they have the most natural resources. They are volcanic islands, and they are mountainous islands, with New Ireland having the maximum elevation at 2,340 m above sea level. They are tropical islands and are covered mostly with tropical rainforests, and even though they are not developed, they do have a big potential.
