Problem: Information:  - Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. Coral reefs are built by colonies of tiny animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups. The polyps belong to a group of animals known as Cnidaria, which also includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons which support and protect the coral polyps. Most reefs grow best in warm, shallow, clear, sunny and agitated waters.  - A lagoon is a shallow body of water separated from a larger body of water by barrier islands or reefs. Lagoons are commonly divided into coastal lagoons and atoll lagoons. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around many parts of the world.  - Tahanea Atoll is an atoll of the Tuamotu Archipelago in French Polynesia . It is located 12 km to the east of Faaite Atoll . Tahanea Atoll measures 48 km in length with a maximum width of 15.2 km. The southern reef fringing the atoll is wider than the northern one , but the largest islands are on the narrower northern rim . Tahanea has a wide and deep lagoon with a surface of 545 km² . There are three deep , navigable , passes into the lagoon , which are called Motupuapua , Teavatapu and Otao . Tahanea is uninhabited , but visited occasionally by islanders from neighbouring atolls .  - An atoll (, , , or ), sometimes called a coral atoll, is a ring-shaped coral reef including a coral rim that encircles a lagoon partially or completely. There may be coral islands/cays on the rim.  - French Polynesia  is an overseas collectivity of the French Republic; " (COM)", sometimes unofficially referred to as an overseas country; " (POM)". It is composed of 118 geographically dispersed islands and atolls stretching over an expanse of more than in the South Pacific Ocean. Its total land area is .  - The Tuamotus or the Tuamotu Archipelago (officially "") are a French Polynesian chain of almost 80 islands and atolls, stretching from the northwest to the southeast over an area of the southern Pacific Ocean roughly the size of Western Europe, with a land area of and 16,000 inhabitants, forming the largest chain of atolls in the world. Its major islands are Anaa, Fakarava, Hao and Makemo.  - The French overseas collectivities (or "COM"), like the French regions, are first-order administrative divisions of France. The COMs include some former French overseas territories and other French overseas entities with a particular status, all of which became COMs by constitutional reform on 28 March 2003. The COMs should not be confused with the overseas regions and overseas departments which have no particular status. As integral parts of France, overseas collectivities are represented in the National Assembly, Senate and Economic and Social Council. Only one COM, Saint Martin, is part of the European Union and can vote to elect members of the European Parliament (MEP). The Pacific COMs use the CFP franc, a currency pegged to the euro, whereas the Atlantic COMs use the euro directly.  As of 31 March 2011, there were five COMs:  - Anaa, Nganaa-nui (or Ara-ura) is an atoll in the Tuamotu archipelago, in French Polynesia. It is located in the north-west of the archipelago, 350 km to the east of Tahiti. It is oval in shape, 29.5 km in length and 6.5 km wide, with a total land area of 38 km² and a population of 500. The atoll is made up by eleven small barren islands with deeper and more fertile soil than other atolls in the Tuamotus. The lagoon is shallow, without entrance, and formed by three main basins. Although it does not have any navigable access, the water of the lagoon renews by several small channels that can be crossed walking.  - Corals are marine invertebrates in the class Anthozoa of phylum Cnidaria. They typically live in compact colonies of many identical individual polyps. The group includes the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton.  - Faaite, or Faaiti is an atoll of the Tuamotus in French Polynesia. It is located to the north of Anaa Atoll. The total surface of the atoll is Its dry land area is . Its length is and its width . The total population is 401 inhabitants.  - A cay (or ), also spelled caye or key, is a small, low-elevation, sandy island on the surface of a coral reef. Cays occur in tropical environments throughout the Pacific, Atlantic and Indian Oceans (including in the Caribbean and on the Great Barrier Reef and Belize Barrier Reef).  - A coral island is a type of island formed from coral detritus and associated organic material. They occur in tropical and sub-tropical areas, typically as part of coral reefs which have grown to cover a far larger area under the sea.

Problem: Information:  - Junior Civitan International is a student - led service organization for middle and high school students . There are 11,000 Junior Civitan members in 400 clubs in North America , Africa , Asia , and Europe . It is the longest lasting project of its parent organization Civitan International .  - A service club or service organization is a voluntary non-profit organization where members meet regularly to perform charitable works either by direct hands-on efforts or by raising money for other organizations. A service club is defined firstly by its service mission and secondly its membership benefits, such as social occasions, networking, and personal growth opportunities that encourage involvement.  - Civitan International, based in Birmingham, Alabama, is an association of community service clubs founded in 1917. The organization aims "to build good citizenship by providing a volunteer organization of clubs dedicated to serving individual and community needs with an emphasis on helping people with developmental disabilities." The organization includes 40,000 members (referred to as "Civitans") in almost 1,000 clubs around the world.  - Alabama is a state in the southeastern region of the United States.
