Ex Input:
Context: Reggae is a music genre that originated in Jamaica in the late 1960s. The term also denotes the modern popular music of Jamaica and its diaspora. A 1968 single by Toots and the Maytals "Do the Reggay" was the first popular song to use the word "reggae," effectively naming the genre and introducing it to a global audience. While sometimes used in a broad sense to refer to most types of popular Jamaican dance music, the term "reggae" more properly denotes a particular music style that was strongly influenced by traditional mento as well as American jazz and rhythm and blues, especially the New Orleans R&B practiced by Fats Domino and Allen Toussaint, and evolved out of the earlier genres ska and rocksteady. Reggae usually relates news, social gossip, and political comment. Reggae spread into a commercialized jazz field, being known first as Rudie Blues, then Ska, later Blue Beat, and Rock Steady. It is instantly recognizable from the counterpoint between the bass and drum downbeat, and the offbeat rhythm section. The immediate origins of reggae were in ska and rock steady; from the latter, reggae took over the use of the bass as a percussion instrument., Tula Paulina "Tulisa" Contostavlos (born 13 July 1988) is an English singer-songwriter, "The X Factor" judge, actress, and television personality.

Follow-up albums "Showtime", "Maths + English", and "Tongue n' Cheek" have been critically acclaimed and certified gold, with "Tongue n' Cheek" going platinum for sales exceeding 300,000 units in the United Kingdom., Hip hop is a subcultural art movement that was formed during the early 1970s primarily by African-American and Afro Puerto Rican youths residing in the South Bronx in New York City. Art historian Robert Farris Thompson describes the demographics of the youth that characterize the South Bronx in the early 1970s as "English-speaking blacks from Barbados" like Grandmaster Flash, "black Jamaicans" like DJ Kool Herc, "thousands of Nuyoricans", who introduced the rhythms from Salsa (music), as well as Afro conga and bonga drums, as well as many who emulated the sounds of Tito Puente and Willie Colón with existing styles of musical styles from jazz to funk associated with African Americans prior to the 1970s. Hip hop music became popular outside of the African-American community in the late 1980s. After the rise of new media platforms and Web 2.0 technology of the Internet, fans would primarily consume the musical genre through social networking sites (SNS) beginning with Myspace evolving to notable mobile apps like YouTube, Worldstarhiphop, SoundCloud, and Spotify., Clubland TV is a music channel broadcasting on Sky channel 383 and Virgin Media  channel 345 in the United Kingdom.

Known for his hard hitting lyrics and intricate rhyme schemes, he is associated and has toured internationally with such acts as Kano and was a member of NASTY Crew., Music is an art form and cultural activity whose medium is sound and silence, which exist in time. The common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and vocal techniques ranging from singing to rapping; there are solely instrumental pieces, solely vocal pieces (such as songs without instrumental accompaniment) and pieces that combine singing and instruments. The word derives from Greek  ("mousike"; "art of the Muses"). In its most general form, the activities describing music as an art form include the production of works of music (songs, tunes, symphonies, and so on), the criticism of music, the study of the history of music, and the aesthetic examination of music. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound.", Boy in da Corner is the debut album by English rapper and producer Dizzee Rascal.

A pioneer of indeterminacy in music, electroacoustic music, and non-standard use of musical instruments, Cage was one of the leading figures of the post-war avant-garde. Critics have lauded him as one of the most influential American composers of the 20th century. He was also instrumental in the development of modern dance, mostly through his association with choreographer Merce Cunningham, who was also Cage's romantic partner for most of their lives., Patrick Chukwuemeka Okogwu (born 7 November 1988), better known by his stage name Tinie Tempah, is an English rapper, singer, songwriter and record producer.

His fourth studio album, "Konnichiwa", was released on 6 May 2016 to critical acclaim, winning that year's Mercury Prize., In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a transmission medium such as air or water. In physiology and psychology, sound is the "reception" of such waves and their "perception" by the brain. Humans can hear sound waves with frequencies between about 20 Hz and 20 kHz. Sound above 20 kHz is ultrasound and below 20 Hz is infrasound. Other animals have different hearing ranges., Cascada (Spanish for "Waterfall") is a German dance music act founded in 2004 by singer Natalie Horler, DJ Manian and DJ Yanou. They are best known for their hit singles "Everytime We Touch", "What Hurts the Most" and "Evacuate the Dancefloor".

The prize was originally sponsored by Mercury Communications, a brand owned by Cable & Wireless, from which the prize gets its name. It was later sponsored by Technics (1998 to 2001), Panasonic (2002 and 2003), Nationwide Building Society (2004 to 2008) and Barclaycard (200914). The 2015 prize was sponsored by the BBC, while in 2016 it was announced that a three-year deal had been struck with Hyundai to sponsor the event., Music is found in every known culture, past and present, varying widely between times and places. Since all people of the world, including the most isolated tribal groups, have a form of music, it may be concluded that music is likely to have been present in the ancestral population prior to the dispersal of humans around the world. Consequently, music may have been in existence for at least 55,000 years and the first music may have been invented in Africa and then evolved to become a fundamental constituent of human life., Costadinos Contostavlos (born 11 June 1987), better known by his stage name Dappy, is an English singer, songwriter, rapper, and actor.

Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union., Camden Town, often shortened to Camden (ambiguously also used for the much larger London Borough of Camden of which it is the central neighbourhood), is an inner city district of northwest London, north of the centre of London.

Context: Promerycochoerus ( `` Before Merycochoerus '' or `` Before Ruminating Hog '' ) is an extinct genus of hippopotamus - like oreodont artiodactyl that lived in Central North America during the Early Miocene . The 1 m ( 3 ft 4 in ) long creature is thought to have been amphibious , as all species possessed an elongated , barrel - shaped body and short limbs that are typical adaptations found in semi-aquatic mammals . P. superbus had a long tapir - like face , while P. carrikeri had a short , somewhat pig - like face ., The Neogene is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period million years ago (Mya) to the beginning of the present Quaternary Period Mya. The Neogene is sub-divided into two epochs, the earlier Miocene and the later Pliocene. Some geologists assert that the Neogene cannot be clearly delineated from the modern geological period, the Quaternary., A genus ( genera) is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus., Sir Charles Lyell, 1st Baronet, (14 November 1797  22 February 1875) was a British lawyer and the foremost geologist of his day. He is best known as the author of "Principles of Geology", which popularized James Hutton's concepts of uniformitarianismthe idea that the Earth was shaped by the same processes still in operation today. "Principles of Geology" also challenged theories popularized by Georges Cuvier, which were the most accepted and circulated ideas about geology in England at the time., Kenya, officially the Republic of Kenya, is a country in Africa and a founding member of the East African Community (EAC). Its capital and largest city is Nairobi. Kenya's territory lies on the equator and overlies the East African Rift covering a diverse and expansive terrain that extends roughly from Lake Victoria to Lake Turkana (formerly called Lake Rudolf) and further south-east to the Indian Ocean. It is bordered by Tanzania to the south and southwest, Uganda to the west, South Sudan to the north-west, Ethiopia to the north and Somalia to the north-east. Kenya covers , and had a population of approximately 45 million people in July 2014., The Atlantic Ocean is the second largest of the world's oceans with a total area of about . It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World"., Cetacea are a widely distributed and diverse clade of aquatic mammals that today consists of the whales, dolphins, and porpoises. Cetaceans are carnivorous and finned. Most species live in the sea, some in rivers. The name is derived from the Latin "cetus" "whale" and Greek "ketos" "huge fish"., North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere. It can also be considered a northern subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, and to the southeast by South America and the Caribbean Sea., A rhinoceros (meaning "nose horn"), often abbreviated to rhino, is one of any five extant species of odd-toed ungulates in the family Rhinocerotidae, as well as any of the numerous extinct species. Two of these extant species are native to Africa and three to Southern Asia., Elephants are large mammals of the family Elephantidae and the order Proboscidea. Two species are traditionally recognised, the African elephant ("Loxodonta africana") and the Asian elephant ("Elephas maximus"), although some evidence suggests that African bush elephants and African forest elephants are separate species ("L. africana" and "L. cyclotis" respectively). Elephants are scattered throughout sub-Saharan Africa, South Asia, and Southeast Asia. Elephantidae is the only surviving family of the order Proboscidea; other, now extinct, members of the order include deinotheres, gomphotheres, mammoths, and mastodons. Male African elephants are the largest extant terrestrial animals and can reach a height of and weigh . All elephants have several distinctive features, the most notable of which is a long trunk or proboscis, used for many purposes, particularly breathing, lifting water, and grasping objects. Their incisors grow into tusks, which can serve as weapons and as tools for moving objects and digging. Elephants' large ear flaps help to control their body temperature. Their pillar-like legs can carry their great weight. African elephants have larger ears and concave backs while Asian elephants have smaller ears and convex or level backs., Sub-Saharan Africa is, geographically, the area of the continent of Africa that lies south of the Sahara desert. According to the UN, it consists of all African countries that are fully or partially located south of the Sahara. It contrasts with North Africa, whose territories are part of the League of Arab states within the Arab world. Somalia, Djibouti, Comoros and Mauritania are geographically in Sub-Saharan Africa, but are likewise Arab states and part of the Arab world., Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. They are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises. Whales, dolphins and porpoises belong to the order Cetartiodactyla with even-toed ungulates and their closest living relatives are the hippopotamuses, having diverged about 40 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have split apart around 34 million years ago. The whales comprise eight extant families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale), Eschrichtiidae (the gray whale), Monodontidae (belugas and narwhals), Physeteridae (the sperm whale), Kogiidae (the dwarf and pygmy sperm whale), and Ziphiidae (the beaked whales)., A continent is one of several very large landmasses on Earth. Generally identified by convention rather than any strict criteria, up to seven regions are commonly regarded as continents. Ordered from largest in size to smallest, they are: Asia, Africa, North America, South America, Antarctica, Europe, and Australia. In geology, areas of continental crust include regions covered with water., The common hippopotamus ("Hippopotamus amphibius"), or hippo, is a large, mostly herbivorous mammal in sub-Saharan Africa, and one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus ("Choeropsis liberiensis" or "Hexaprotodon liberiensis"). The name comes from the ancient Greek for "river horse". After the elephant and rhinoceros, the common hippopotamus is the third-largest type of land mammal and the heaviest extant artiodactyl. Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the Hippopotamidae are cetaceans (whales, porpoises, etc.) from which they diverged about . The common ancestor of whales and hippos split from other even-toed ungulates around . The earliest known hippopotamus fossils, belonging to the genus "Kenyapotamus" in Africa, date to around ., The Miocene is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Sir Charles Lyell. Its name comes from the Greek words (', less) and (', new) and means "less recent" because it has 18% fewer modern sea invertebrates than the Pliocene. The Miocene follows the Oligocene Epoch and is followed by the Pliocene Epoch., Ungulates (pronounced ) are any members of a diverse group of primarily large mammals that includes odd-toed ungulates such as horses and rhinoceroses, and even-toed ungulates such as cattle, pigs, giraffes, camels, deer, and hippopotami. Most terrestrial ungulates use the tips of their toes, usually hoofed, to sustain their whole body weight while moving. The term means, roughly, "being hoofed" or "hoofed animal". As a descriptive term, "ungulate" normally excludes cetaceans (whales, dolphins, porpoises), as they do not possess most of the typical morphological characteristics of ungulates, but recent discoveries indicate that they are descended from early artiodactyls. Ungulates are typically herbivorous (though some species are omnivorous, such as pigs), and many employ specialized gut bacteria to allow them to digest cellulose, as in the case of ruminants. They inhabit a wide range of habitats, from jungles, plains and rivers., A pig is any of the animals in the genus Sus, within the Suidae family of even-toed ungulates. Pigs include the domestic pig and its ancestor, the common Eurasian wild boar ("Sus scrofa"), along with other species; related creatures outside the genus include the peccary, the babirusa, and the warthog. Pigs, like all suids, are native to the Eurasian and African continents. Juvenile pigs are known as piglets. Pigs are highly social and intelligent animals., The pygmy hippopotamus ("Choeropsis liberiensis" or "Hexaprotodon liberiensis") is a small hippopotamid which is native to the forests and swamps of West Africa, primarily in Liberia with small populations in Sierra Leone, Guinea, and Ivory Coast., Hexaprotodon is a genus of Hippopotamidae that is sometimes applied to the pygmy hippopotamus. Pygmy hippos may be classified as either "Choeropsis liberiensis" or "Hexaprotodon liberiensis". The name "Hexaprotodon" means "six front teeth" as some of the fossil forms have three pairs of incisors.
The genus Hexaprotodon also includes a number of rarely studied extinct species from Asia, sometimes labeled "Asian Hippopotami.", Invertebrates are animals that neither possess nor develop a vertebral column (commonly known as a "backbone" or "spine"), derived from the notochord. This includes all animals apart from the subphylum Vertebrata. Familiar examples of invertebrates include insects; crabs, lobsters and their kin; snails, clams, octopuses and their kin; starfish, sea-urchins and their kin; and worms., Porpoises are a group of fully aquatic marine mammals that are sometimes referred to as mereswine, all of which are classified under the family Phocoenidae, parvorder Odontoceti (toothed whales). There are six extant species of porpoise. They are small toothed whales that are very closely related to oceanic dolphins. The most obvious visible difference between the two groups is that porpoises have shorter beaks and flattened, spade-shaped teeth distinct from the conical teeth of dolphins. Porpoises, and other cetaceans, belong to the clade Cetartiodactyla with even-toed ungulates, and their closest living relatives are the hippopotamuses, having diverged from them about 40 million years ago., Binomial nomenclature (also called binominal nomenclature or binary nomenclature) is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. For example, humans belong to the genus "Homo" and within this genus to the species "Homo sapiens". The "formal" introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work "Species Plantarum" in 1753. But Gaspard Bauhin, in as early as 1623, had introduced in his book "Pinax theatri botanici" (English, "Illustrated exposition of plants") many names of genera that were later adopted by Linnaeus., In biology, an organism is any contiguous living system, such as an animal, plant, fungus, archaeon, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms. Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs., Merycochoerus is an extinct genus of terrestrial herbivore of the family Merycoidodontidae (oreodont), endemic to North America during the Late Oligocene to Early Miocene (28.416.3 mya) existing for approximately ., The Sahara (", 'the Greatest Desert') is the largest hot desert and the third largest desert in the world after Antarctica and the Arctic. Its area of is comparable to the area of the United States., The Pliocene (also Pleiocene) Epoch is the epoch in the geologic timescale that extends from 5.333 million to 2.58 million years BP. It is the second and youngest epoch of the Neogene Period in the Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian stage, which lasted from 2.588 to 1.806 million years ago, and is now included in the Pleistocene., A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant material., Subject: promerycochoerus, Relation: parent_taxon, Options: (A) animal (B) area (C) areas (D) bacteria (E) balaenidae (F) cetacea (G) choeropsis (H) deer (I) elephantidae (J) elephas (K) hexaprotodon (L) hippopotamus (M) homo (N) idea (O) insects (P) mammal (Q) merycoidodontidae (R) mya (S) mysticeti (T) neogene (U) odontoceti (V) peccary (W) physeteridae (X) pig (Y) plant (Z) proboscidea ([) rhinoceros (\) starfish (]) ungulate (^) vertebrata (_) victoria (`) wild boar

As the world's fifth-largest country by both area and population, it is the largest country to have Portuguese as an official language and the only one in the Americas. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of . It borders all other South American countries except Ecuador and Chile and covers 47.3% of the continent's land area. Its Amazon River basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. This unique environmental heritage makes Brazil one of 17 megadiverse countries, and is the subject of significant global interest and debate regarding deforestation and environmental protection., An ecoregion (ecological region) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than an ecozone. All three of these are either less or greater than an ecosystem. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point)., Mato Grosso do Sul is one of the Central-Western states of Brazil. Its total area of 357,125 square kilometers, or 137,891 square miles, is roughly the same size as Germany., Goiás is a state of Brazil, located in the Center-West region of the country. The name Goiás (formerly, Goyaz) comes from the name of an indigenous community. The original word seems to have been guaiá, a compound of "gua e iá", meaning "the same person" or "people of the same origin." It borders the Federal District and the states of (from north clockwise) Tocantins, Bahia, Minas Gerais, Mato Grosso do Sul and Mato Grosso. 
The most populous state of its region, Goiás is characterized by a landscape of "chapadões" (plateaus). In the height of the drought season, from June to September, the lack of rain makes the level of the Araguaia River go down and exposes almost of beaches, making it the main attraction of the State. At the Emas National Park in the municipality of Mineiros, it is possible to observe the typical fauna and flora from the region. At the Chapada dos Veadeiros the attractions are the canyons, valleys, rapids and waterfalls. Other attractions are the historical city of Goiás (or Old Goiás), from Goiânia, established in the beginning of 18th Century, and Caldas Novas, with its hot water wells attracting more than one million tourists per year. In Brazil's geoeconomic division, Goiás belongs to the Centro-Sul (Center-South), being the northernmost state of the southern portion of Brazil., Minas Gerais is a state in the north of Southeastern Brazil. It ranks as the second most populous, the third by gross domestic product (GDP), and the fourth largest by area in the country. The state's capital and largest city, Belo Horizonte, is a major urban and finance center in Latin America, and is the sixth largest municipality in Brazil, after the cities of São Paulo, Rio de Janeiro, Salvador, Brasilia and Fortaleza, but its metropolitan area is the third largest in Brazil with just over 5,500,000 inhabitants, after those of São Paulo and Rio de Janeiro. Minas Gerais is the state with the largest number of Brazilian presidents., Tocantins is one of the states of Brazil. (From: Tukã, "Toucan" + tï, "beak". lit. "Toucan's beak" in Tupi language). It is the newest of the 26 Brazilian states, formed in 1988 and encompassing what had formerly been the northern two-fifths of the state of Goiás. Tocantins covers and has a population of 1,496,880 (2014 est.). Construction of its capital, Palmas, began in 1989; most of the other cities in the state date to the Portuguese colonial period. With the exception of Araguaína there are few other cities with a significant population in the state. The government has invested in a new capital, a major hydropower dam, railroads and related infrastructure to develop this primarily agricultural area., Mato Grosso ( lit. "Thick Bushes") is one of the states of Brazil, the third largest by area, located in the western part of the country., Galls or cecidia are a kind of swelling growth on the external tissues of plants or animals. Plant galls are abnormal outgrowths of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from fungi and bacteria, to insects and mites. Plant galls are often highly organized structures and because of this the cause of the gall can often be determined without the actual agent being identified. This applies particularly to some insect and mite plant galls. The study of plant galls is known as cecidology., Laevimenes is a small neotropical genus of potter wasps which contains two species which live mainly in the Chaco and Cerrado biogeographical provinces ., The Cerrado is a vast tropical savanna ecoregion of Brazil, particularly in the states of Goiás, Mato Grosso do Sul, Mato Grosso, Tocantins and Minas Gerais. The Cerrado biome core areas are the plateaus in the center of Brazil. The main habitat types of the Cerrado include: forest savanna, wooded savanna, park savanna and gramineous-woody savanna. Savanna wetlands and gallery forests are also included. The second largest of Brazil's major habitat types, after the Amazonian rainforest, the Cerrado accounts for a full 21 percent of the country's land area (extending marginally into Paraguay and Bolivia)., Subject: laevimenes, Relation: parent_taxon, Options: (A) area (B) areas (C) bahia (D) fungi (E) insects (F) plant (G) vespidae
