According to this paragraph, what is the only state in North America that is an archpelago?

Hawaii (/həˈwaɪi/ (listen) hə-WY-ee; Hawaiian: Hawaiʻi [həˈvɐjʔi] or [həˈwɐjʔi]) is a state in the Western United States, about 2,000 miles (3,200 km) from the U.S. mainland in the Pacific Ocean. It is the only U.S. state outside North America, the only state that is an archipelago, and the only state in the tropics.

Hawaii comprises nearly the entire Hawaiian archipelago, 137 volcanic islands spanning 1,500 miles (2,400 km) that are physiographically and ethnologically part of the Polynesian subregion of Oceania.[9] The state's ocean coastline is consequently the fourth-longest in the U.S., at about 750 miles (1,210 km).[d] The eight main islands, from northwest to southeast, are Niʻihau, Kauaʻi, Oʻahu, Molokaʻi, Lānaʻi, Kahoʻolawe, Maui, and Hawaiʻi—the last of these, after which the state is named, is often called the "Big Island" or "Hawaii Island" to avoid confusion with the state or archipelago. The uninhabited Northwestern Hawaiian Islands make up most of the Papahānaumokuākea Marine National Monument, the United States' largest protected area and the fourth-largest in the world.

Hawaii is the only state in North America that is an archipelago, according to this text.
