full_context: Document 1: A cappella: Barbershop music is one of several uniquely American art forms. The earliest reports of this style of a cappella music involved African Americans. The earliest documented quartets all began in barbershops. In 1938, the first formal men's barbershop organization was formed, known as the Society for the Preservation and Encouragement of Barber Shop Quartet Singing in America (S.P.E.B.S.Q.S.A), and in 2004 rebranded itself and officially changed its public name to the Barbershop Harmony Society (BHS). Today the BHS has over 22,000 members in approximately 800 chapters across the United States, and the barbershop style has spread around the world with organizations in many other countries. The Barbershop Harmony Society provides a highly organized competition structure for a cappella quartets and choruses singing in the barbershop style.
Document 2: Dominican Republic: In the Cordillera Central are the four highest peaks in the Caribbean: Pico Duarte (3,098 metres or 10,164 feet above sea level), La Pelona (3,094 metres or 10,151 feet), La Rucilla (3,049 metres or 10,003 feet), and Pico Yaque (2,760 metres or 9,055 feet). In the southwest corner of the country, south of the Cordillera Central, there are two other ranges. The more northerly of the two is the Sierra de Neiba, while in the south the Sierra de Bahoruco is a continuation of the Massif de la Selle in Haiti. There are other, minor mountain ranges, such as the Cordillera Oriental ("Eastern Mountain Range"), Sierra Martín García, Sierra de Yamasá, and Sierra de Samaná.
Document 3: A cappella: Contemporary a cappella includes many vocal groups and bands who add vocal percussion or beatboxing to create a pop/rock/gospel sound, in some cases very similar to bands with instruments. Examples of such professional groups include Straight No Chaser, Pentatonix, The House Jacks, Rockapella, Mosaic, and M-pact. There also remains a strong a cappella presence within Christian music, as some denominations purposefully do not use instruments during worship. Examples of such groups are Take 6, Glad and Acappella. Arrangements of popular music for small a cappella ensembles typically include one voice singing the lead melody, one singing a rhythmic bass line, and the remaining voices contributing chordal or polyphonic accompaniment.

Document 5: Meghalaya: About 70% of the state is forested, of which is dense primary subtropical forest. The Meghalayan forests are considered to be among the richest botanical habitats of Asia. These forests receive abundant rainfall and support a vast variety of floral and faunal biodiversity. A small portion of the forest area in Meghalaya is under what are known as "sacred groves" (see Sacred groves of India). These are small pockets of an ancient forest that have been preserved by the communities for hundreds of years due to religious and cultural beliefs. These forests are reserved for religious rituals and generally remain protected from any exploitation. These sacred groves harbour many rare plant and animal species. The Nokrek Biosphere Reserve in the West Garo Hills and the Balphakram National Park in the South Garo Hills are considered to be the most biodiversity-rich sites in Meghalaya. In addition, Meghalaya has three wildlife sanctuaries. These are the Nongkhyllem Wildlife Sanctuary, the Siju Sanctuary, and the Baghmara Sanctuary, which is also the home of the insect-eating pitcher plant "Nepenthes khasiana" also called "Me'mang Koksi" in local language.

Document 7: A cappella: In July 1943, as a result of the American Federation of Musicians boycott of US recording studios, the a cappella vocal group The Song Spinners had a best-seller with "Comin' In On A Wing And A Prayer". In the 1950s several recording groups, notably The Hi-Los and the Four Freshmen, introduced complex jazz harmonies to a cappella performances. The King's Singers are credited with promoting interest in small-group a cappella performances in the 1960s. In 1983 an a cappella group known as The Flying Pickets had a Christmas 'number one' in the UK with a cover of Yazoo's (known in the US as Yaz) "Only You". A cappella music attained renewed prominence from the late 1980s onward, spurred by the success of Top 40 recordings by artists such as The Manhattan Transfer, Bobby McFerrin, Huey Lewis and the News, All-4-One, The Nylons, Backstreet Boys and Boyz II Men.[citation needed]

Document 11: Mount Chirripó: Mount Chirripó is the highest mountain in Costa Rica with an elevation of 3,820 meters (12,533 feet). It is located in Chirripó National Park and is noted for its ecological wealth. The mountain was named ``Chirripo, ''meaning`` land of eternal waters'', by native Americans because there are many lakes and streams around the mountain. The high peaks in Chirripó National Park and La Amistad International Park host important areas of Talamancan montane forest and Costa Rican Páramo with high endemism and an extremely high biodiversity. The peaks of these mountains constitute sky islands for many species of plants and animals.
