TASK DEFINITION: In this task, you are given a context, a subject, a relation, and many options. Based on the context, from the options select the object entity that has the given relation with the subject. Answer with text (not indexes).
PROBLEM: 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

PROBLEM: Context: Flanimals of the Deep (ISBN 0571234038) is the third book in the Flanimals series from British comedian Ricky Gervais and illustrator Rob Steen. The book was published by Faber and Faber, London, UK on 5 October 2006 and includes such Flanimals as the Mulgi, Flambols, Bif Uddlers and Mulons., Slapstick is a style of humor involving exaggerated physical activity which exceeds the boundaries of normal physical comedy. The term arises from a device developed during the broad, physical comedy style known as Commedia dell'arte in 16th Century Italy. The 'slap stick' consists of two thin slats of wood made from splitting a single long stick, which make a 'slap' when striking another actor, with little force needed to make a loud - and comical - sound., A joke is a display of humour in which words are used within a specific and well-defined narrative structure to make people laugh. It takes the form of a story, usually with dialogue, and ends in a punch line. It is in the punch line that the audience becomes aware that the story contains a second, conflicting meaning. This can be done using a pun or other word play such as irony, a logical incompatibility, nonsense or other means. Linguist Robert Hetzron offers the definition:, A book is a set of written, printed, illustrated, or blank sheets, made of paper, parchment, or other materials, fastened together to hinge at one side, with text and/or images printed in ink. A single sheet within a book is a leaf, and each side of a leaf is a page. A set of text-filled or illustrated pages produced in electronic format is known as an electronic book, or e-book. , Rob Steen is the illustrator of the books "Flanimals", "More Flanimals", "Flanimals of the Deep", "" and Flanimals Pop-Up. Other work includes "Erf", and "The Thing's in Ted's Head"., An artist is a person engaged in one or more of any of a broad spectrum of activities related to creating art, practicing the arts or demonstrating an art. The common usage in both everyday speech and academic discourse is a practitioner in the visual arts only. The term is often used in the entertainment business, especially in a business context, for musicians and other performers (less often for actors). "Artiste" (the French for artist) is a variant used in English only in this context. Use of the term to describe writers, for example, is valid, but less common, and mostly restricted to contexts like criticism., Prop comedy is a comedy genre in which performers use humorous objects, or conventional objects in humorous ways. The stages and films term "prop", an abbreviation of "property", refers to any object an actor handles in the course of a performance. Though some form of prop comedy has likely existed as long as there have been comedians, the genre reached its zenith in the vaudeville era. The vaudeville team Olsen and Johnson used prop comedy extensively in their long running Broadway revue "Hellzapoppin"., Flanimals : The Day of the Bletchling ( ISBN 0571238513 ) is the fourth book in the Flanimals series from British comedian Ricky Gervais and illustrator Rob Steen . The book was published on 4 October 2007 and focuses on the Flanimals teaming up against an enormous swarm of Bletchling , a species that seeks to wipe out all other Flanimal life . The hardcover version of the book comes with a poster featuring a Clunge Ambler and a Molf , in a parody of the movie Jaws ., A comedian or comic is a person who seeks to entertain an audience, primarily by making them laugh. This might be through jokes or amusing situations, or acting a fool, as in slapstick, or employing prop comedy. A comedian who addresses an audience directly is called a stand-up comic., Richard "Ricky" Dene Gervais (born 25 June 1961) is an English comedian, actor, writer, producer, director, singer, and musician., An illustrator is an artist who specializes in enhancing writing or elucidating concepts by providing a visual representation that corresponds to the content of the associated text or idea. The illustration may be intended to clarify complicated concepts or objects that are difficult to describe textually, which is the reason illustrations are often found in children's books., Subject: flanimals: the day of the bletchling, Relation: publisher, Options: (A) actor (B) definition (C) dell (D) english (E) faber and faber (F) leaf (G) punch (H) spectrum

PROBLEM: Context: A royal charter is a formal document issued by a monarch as letters patent, granting a right or power to an individual or a body corporate. They were, and are still, used to establish significant organisations such as cities (with municipal charters) or universities and learned societies. Charters should be distinguished from warrants and letters of appointment, as they have perpetual effect. Typically, a Royal Charter is produced as a high-quality work of calligraphy on vellum. The British monarchy has issued over 980 royal charters. Of these about 750 remain in existence. The earliest was to the town of Tain in 1066, making it the oldest Royal Burgh in Scotland, followed by the University of Cambridge in 1231. Charters continue to be issued by the British Crown, a recent example being that awarded to the Chartered Institute for the Management of Sport and Physical Activity, on 7 April 2011., Ralph Vaughan Williams (12 October 1872 26 August 1958) was an English composer. His works include operas, ballets, chamber music, secular and religious vocal pieces and orchestral compositions including nine symphonies, written over nearly fifty years. Strongly influenced by Tudor music and English folk-song, his output marked a decisive break in British music from its German-dominated style of the 19th century., The Royal College of Music is a conservatoire established by royal charter in 1882, located in South Kensington, London, UK. It offers training from the undergraduate to the doctoral level in all aspects of Western Art including performance, composition, conducting, music theory and history. The RCM also undertakes research, with particular strengths in performance practice and performance science. The college is one of the four conservatories of the Associated Board of the Royal Schools of Music and a member of Conservatoires UK. Its buildings are directly opposite the Royal Albert Hall on Prince Consort Road, next to Imperial College and among the museums and cultural centres of Albertopolis., Lisbon is the capital and the largest city of Portugal, with a population of 552,700 within its administrative limits in an area of 100.05km. Its urban area extends beyond the city's administrative limits with a population of around 2.7 million people, being the 11th-most populous urban area in the European Union. About 2.8 million people live in the Lisbon Metropolitan Area (which represents approximately 27% of the country's population). It is continental Europe's westernmost capital city and the only one along the Atlantic coast. Lisbon lies in the western Iberian Peninsula on the Atlantic Ocean and the River Tagus. The westernmost areas of its metro area is the westernmost point of Continental Europe., Brazilian Portuguese (' or ' ) is a set of dialects of the Portuguese language used mostly in Brazil. It is spoken by virtually all of the 200 million inhabitants of Brazil and spoken widely across the Brazilian diaspora, today consisting of about two million Brazilians who have emigrated to other countries., Edward Benjamin Britten, Baron Britten (22 November 1913 4 December 1976) was an English composer, conductor and pianist. He was a central figure of 20th-century British classical music, with a range of works including opera, other vocal music, orchestral and chamber pieces. His best-known works include the opera "Peter Grimes" (1945), the "War Requiem" (1962) and the orchestral showpiece "The Young Person's Guide to the Orchestra" (1945)., Portuguese (or, in full) is a Romance language and the sole official language of Angola, Brazil, Cape Verde, Guinea-Bissau, Mozambique, Portugal, and Sao Tome and Principe. It also has co-official language status in East Timor, Equatorial Guinea and Macau. As the result of expansion during colonial times, a cultural presence of Portuguese and Portuguese creole speakers are also found in Goa, Daman and Diu in India; in Batticaloa on the east coast of Sri Lanka; in the Indonesian island of Flores; and in Malacca in Malaysia., An urban area is a human settlement with high population density and infrastructure of built environment. Urban areas are created through urbanization and are categorized by urban morphology as cities, towns, conurbations or suburbs. In urbanism, the term contrasts to rural areas such as villages and hamlets and in urban sociology or urban anthropology it contrasts with natural environment. The creation of early predecessors of urban areas during the urban revolution led to the creation of human civilization with modern urban planning, which along with other human activities such as exploitation of natural resources leads to human impact on the environment., Henry Purcell (or ; c. 10 September 1659 21 November 1695) was an English composer. Although incorporating Italian and French stylistic elements into his compositions, Purcell's legacy was a uniquely English form of Baroque music. He is generally considered to be one of the greatest English composers; no other native-born English composer approached his fame until Edward Elgar, Ralph Vaughan Williams, and Benjamin Britten in the 20th century., Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries., Sir Edward William Elgar, 1st Baronet (2 June 1857 23 February 1934) was an English composer, many of whose works have entered the British and international classical concert repertoire. Among his best-known compositions are orchestral works including the "Enigma Variations", the "Pomp and Circumstance Marches", concertos for violin and cello, and two symphonies. He also composed choral works, including "The Dream of Gerontius", chamber music and songs. He was appointed Master of the King's Musick in 1924., The Tagus (Ancient Greek: "Tagos") is the longest river on the Iberian Peninsula. It is long, in Spain, along the border between Portugal and Spain and in Portugal, where it empties into the Atlantic Ocean near Lisbon. It drains an area of (the second largest in the Iberian peninsula after the Douro). The Tagus is highly utilized for most of its course. Several dams and diversions supply drinking water to most of central Spain, including Madrid, and Portugal, while dozens of hydroelectric stations create power. Between dams it follows a very constricted course, but after Almourol it enters a vast alluvial valley prone to flooding. At its mouth is a large estuary on which the port city of Lisbon is situated., Jennifer Smith ( born 13 July 1945 ) is a Portuguese soprano singer . Born in Lisbon , Jennifer Smith graduated from the Lisbon Conservatory of Music and came to London on a Gulbenkian scholarship . Her varied recording career includes opera and recital , from baroque to modern . Her ability to sing in European - Portuguese and Brazilian Portuguese makes her a specialist in the music of those countries ( composers such as Joao de Sousa Carvalho , Francisco Antonio de Almeida , Carlos de Seixas and Antonio Teixeira ) . She appeared in Tony Palmer 's television film on Henry Purcell in 1995 . She was professor of vocal studies at the Royal College of Music . Because of her name and her residence in London , she is sometimes classified as an English singer ., The Brazilian diaspora comprises Brazilians who have migrated to other countries, a fairly recent phenomenon that has been driven mainly by economic problems that afflicted Brazil from the ending of the military dictatorship in the 1980s to the early 2000s (decade)., The European Union (EU) is a political and economic union of member states that are located primarily in Europe. It has an area of , and an estimated population of over 510 million. The EU has developed an internal single market through a standardised system of laws that apply in all member states. EU policies aim to ensure the free movement of people, goods, services, and capital within the internal market, enact legislation in justice and home affairs, and maintain common policies on trade, agriculture, fisheries, and regional development. Within the Schengen Area, passport controls have been abolished. A monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency., Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America. 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., Baroque music (or ) is a style of Western art music composed from approximately 1600 to 1750. This era followed the Renaissance music era, and was followed in turn by the Classical era. Baroque music forms a major portion of the "classical music" canon, being widely studied, performed, and listened to. Key composers of the Baroque era include Johann Sebastian Bach, Antonio Vivaldi, George Frideric Handel, Claudio Monteverdi, Domenico Scarlatti, Alessandro Scarlatti, Henry Purcell, Georg Philipp Telemann, Jean-Baptiste Lully, Jean-Philippe Rameau, Marc-Antoine Charpentier, Arcangelo Corelli, Tomaso Albinoni, Francois Couperin, Giuseppe Tartini, Heinrich Schutz, Giovanni Battista Pergolesi, Dieterich Buxtehude, and Johann Pachelbel., Subject: jennifer smith , Relation: field_of_work, Options: (A) anthropology (B) asia (C) classical music (D) composer (E) conductor (F) english (G) french (H) history (I) language (J) management (K) military (L) music (M) natural environment (N) opera (O) river (P) sociology (Q) trade (R) training (S) urbanization
