Example Input: Context: Pantera was an American heavy metal band from Arlington, Texas. The group was formed in 1981 by the Abbott brothers  drummer Vinnie Paul and guitarist Dimebag Darrell  along with vocalist Terry Glaze. Bassist Rex Brown joined the band the following year, replacing the original unofficial bass guitarist Tommy D. Bradford. Having started as a glam metal band, Pantera released four albums during the 1980s. Looking for a new and heavier sound, Pantera replaced Glaze with Phil Anselmo in late 1986 and released "Power Metal" in 1988. With its fifth album, 1990's "Cowboys from Hell", Pantera introduced a groove metal sound. Pantera's sixth album, 1992's "Vulgar Display of Power", exhibited an even heavier sound. "Far Beyond Driven" (1994) debuted at number one on the "Billboard" 200., Louisiana (or  ; Louisiana Creole: "Léta de la Lwizyàn") is a state located in the southern region of the United States. Louisiana is the 31st most extensive and the 25th most populous of the 50 United States. Its capital is Baton Rouge and largest city is New Orleans. Louisiana is the only state in the U.S. with political subdivisions termed parishes, which are the local government's equivalent to counties. The largest parish by population is East Baton Rouge Parish, and the largest by total area is Plaquemines. Louisiana is bordered by Arkansas to the north, Mississippi to the east, Texas to the west, and the Gulf of Mexico to the south., Terrence Lee "Terry" Glaze (born November 29, 1964 in Columbus) is an Ohio-born and Texas raised singer and guitarist who is most known for his work in American heavy metal bands Lord Tracy and Pantera., The Great Southern Trendkill is the eighth studio album by American heavy metal band Pantera , released on May 7 , 1996 by EastWest Records . It reached number 4 on the Billboard 200 chart , and managed to stay on the chart for over 16 weeks . Due to tension and conflicts within the band , Phil Anselmo recorded the vocals alone at Trent Reznor 's Nothing Studios in New Orleans while Dimebag Darrell , Rex Brown and Vinnie Paul recorded the music at Chasin Jason Studios in Dallas ., Glam metal (also known as hair metal and often used synonymously with pop metal) is a subgenre of heavy metal and hard rock. It often combines elements of those genres with blues, adding catchy pop-influenced hooks and guitar riffs, while borrowing from the fashion of 1970s glam rock., Far Beyond Driven is the seventh studio album by American heavy metal band Pantera, released on March 22, 1994 by EastWest Records. The album is Pantera's fastest-selling album. The album peaked at number 1 on the Billboard 200 and was certified Platinum by the RIAA. Also, the album was certified Platinum by the Canadian Recording Industry Association. "Far Beyond Driven" is the first album by Pantera where the band's guitarist Darrell Abbott is credited as "Dimebag Darrell", having changed his nickname from "Diamond Darrell" the previous year. The Japanese and the "Driven Downunder Tour '94 Souvenir Collection" editions contain a bonus thirteenth track, "The Badge", a Poison Idea cover. This cover was also featured on "The Crow" soundtrack., Nine Inch Nails (abbreviated as NIN and stylized as NI) is an American industrial rock band founded in 1988 by Trent Reznor in Cleveland, Ohio. The band released two influential albums during the 1990s  "The Downward Spiral" (1994) and "The Fragile" (1999) and has record sales exceeding over 20 million copies worldwide, with 10 million sales certified in the United States alone., A port is a location on a coast or shore containing one or more harbors where ships can dock and transfer people or cargo to or from land. Port locations are selected to optimize access to land and navigable water, for commercial demand, and for shelter from wind and waves. Ports with deeper water are rarer, but can handle larger ships. Since ports throughout history handled every kind of traffic, support and storage facilities vary widely, may extend for miles, and dominate the local economy. Some ports have an important military role., Philip Hansen "Phil" Anselmo (born June 30, 1968) is an American heavy metal musician who is best known as the lead vocalist for Pantera. He is also the owner of Housecore Records and has been involved with several other bands., The guitar is a musical instrument classified as a string instrument with anywhere from four to 18 strings, usually having six. The sound is projected either acoustically, using a hollow wooden or plastic and wood box (for an acoustic guitar), or through electrical amplifier and a speaker (for an electric guitar). It is typically played by strumming or plucking the strings with the fingers, thumb and/or fingernails of the right hand or with a pick while fretting (or pressing against the frets) the strings with the fingers of the left hand. The guitar is a type of chordophone, traditionally constructed from wood and strung with either gut, nylon or steel strings and distinguished from other chordophones by its construction and tuning. The modern guitar was preceded by the gittern, the vihuela, the four-course Renaissance guitar, and the five-course baroque guitar, all of which contributed to the development of the modern six-string instrument., Vincent Paul Abbott, also known as Vinnie Paul (born March 11, 1964), is an American professional drummer and producer who is best known for being a former member, and co-founder, of the heavy metal band Pantera. He is currently a member of supergroup Hellyeah. He also co-founded the heavy metal band Damageplan in 2003 with his late younger brother, Dimebag Darrell., San Antonio (Spanish for "Saint Anthony"), officially the City of San Antonio, is the seventh-most populated city in the United States and the second-most populous city in the state of Texas, with a population of 1,409,019. It was the fastest growing of the top 10 largest cities in the United States from 2000 to 2010, and the second from 1990 to 2000. The city straddles South Texas and Central Texas and is on the southwestern corner of an urban megaregion known as the Texas Triangle., Vulgar Display of Power is the sixth studio album by the American heavy metal band Pantera, released on February 25, 1992 through Atco Records. One of the most influential heavy metal albums of the 1990s, "Vulgar Display of Power" has been described as "one of the defining albums of the groove-metal genre". Several songs from this release have become some of the band's best known, such as "Mouth for War", "A New Level", "Walk", "Fucking Hostile", and "This Love"., A drummer is a musician who plays drums, which includes a drum kit ("drum set" or "trap set", including cymbals) and accessory-based hardware which includes an assortment of pedals and standing support mechanisms, marching percussion or any musical instrument that is struck within the context of a wide assortment of musical genres. The term percussionist applies to a musician who performs struck musical instruments of numerous diverse shapes, sizes and applications. Most contemporary western ensembles bands for rock, pop, jazz, R&B etc. include a drummer for purposes including timekeeping and embellishing the musical timbre. Most drummers of this particular designation work within the context of a larger contingent (a.k.a. rhythm section) that may also include, keyboard (a percussion instrument) or guitar, auxiliary percussion (often of non western origin) and bass (bass viol or electric). Said ensembles may also include melodic based mallet percussion including: vibraphone, marimba or xylophone. The rhythm section, being the core metronomic foundation with which other melodic instruments, including voices, may present the harmonic/melodic portion of the material., Cowboys from Hell is the major label debut and fifth overall studio album by American heavy metal band Pantera, released on July 24, 1990 through Atco Records., Texas is the second largest state in the United States by both area and population. Geographically located in the south central part of the country, Texas shares borders with the U.S. states of Louisiana to the east, Arkansas to the northeast, Oklahoma to the north, New Mexico to the west, and the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the southwest, while the Gulf of Mexico is to the southeast., The United States Census Bureau (USCB; officially the Bureau of the Census, as defined in Title ) is a principal agency of the U.S. Federal Statistical System, responsible for producing data about the American people and economy., Interscope Records is an American record company. A division of Interscope Geffen A&M Records, its parent company is the Universal Music Group, a subsidiary of Vivendi S.A., Groove metal (also known as post-thrash or neo-thrash) is a subgenre of heavy metal music. It is often used to describe Pantera, Exhorder and Machine Head. At its core, groove metal takes the intensity and sonic qualities of thrash metal and plays them at mid-tempo, with most bands making only occasional forays into fast tempo., Michael Trent Reznor (born May 17, 1965), known professionally as Trent Reznor, is an American singer, songwriter, musician, record producer, and film score composer. As a vocalist and multi-instrumentalist, he is best known as the founder and principal songwriter of industrial rock project Nine Inch Nails. His first release under this pseudonym, the 1989 album "Pretty Hate Machine", was a commercial and critical success. He has since released eight studio albums. He left Interscope Records in 2007 and was an independent recording artist until signing with Columbia Records in 2012., Damageplan was an American heavy metal band from Dallas, Texas, formed in 2003. Following the demise of their previous group Pantera, brothers Dimebag Darrell and Vinnie Paul Abbott wanted to start a new band. The pair recruited former Diesel Machine and Halford guitarist Pat Lachman on vocals, and later Bob Zilla on bass. Damageplan released their only studio album "New Found Power" in the United States on February 10, 2004, which debuted at number 38 on the "Billboard" 200, selling 44,676 copies in its first week., Pretty Hate Machine is the debut studio album by American industrial rock band Nine Inch Nails, released on October 20, 1989 by TVT Records in the United States, Island Records in Europe and by Interscope Records and Atlantic Records internationally. The album is compiled of reworked tracks from the band's "Purest Feeling" demo, as well as songs composed after its original recording. Although it was critically and commercially successful (especially for an independent label), Trent Reznor (Nine Inch Nails' only constant band member) feuded with TVT Records during the album's promotion. "Slant Magazine" placed the album at number 50 on its list of the "Best Albums of the 1980s", commenting, "before attempting suicide in "The Downward Spiral" and living with the wrist scars in "The Fragile", "Pretty Hate Machine" sent out sleek, danceable warning shots"., Columbia Records (also known simply as Columbia) is an American record label owned by Sony Music Entertainment (SME), a subsidiary of Sony Corporation of America, Inc., the United States division of Sony Corporation. It was founded in 1887, evolving from an earlier enterprise named the American Graphophone Company, the successor to the Volta Graphophone Company. Columbia is the oldest surviving brand name in the recorded sound business, being the second major record company to produce recorded records. Columbia Records went on to release records by an array of notable singers, instrumentalists, and bands. From 1961 to 1990, its recordings were released outside the U.S. and Canada by the CBS Records label (which was named after the Columbia Broadcasting System) to avoid confusion with the EMI label of the same name, before adopting the Columbia name internationally in 1990. It is one of Sony Music's three flagship record labels alongside RCA Records and Epic Records., Darrell Lance Abbott (August 20, 1966  December 8, 2004), also known as Diamond Darrell and Dimebag Darrell, was an American guitarist and songwriter best known as a founding member of two bands, Pantera and Damageplan, alongside his brother, Vinnie Paul. He was considered to be one of the driving forces behind groove metal., Dallas is a major city in the state of Texas and is the largest urban center of the fourth most populous metropolitan area in the United States. The city proper ranks ninth in the U.S. and third in Texas after Houston and San Antonio. The city's prominence arose from its historical importance as a center for the oil and cotton industries, and its position along numerous railroad lines. The bulk of the city is in Dallas County, of which it is the county seat; however, sections of the city are located in Collin, Denton, Kaufman, and Rockwall counties. According to the 2010 United States Census, the city had a population of 1,197,816. The United States Census Bureau's estimate for the city's population increased to 1,300,092 as of July 1, 2015., Hellyeah is an American heavy metal supergroup, consisting of Mudvayne vocalist Chad Gray, former Nothingface guitarist Tom Maxwell, bass player Kyle Sanders, guitarist Christian Brady and former Pantera and Damageplan drummer Vinnie Paul. The idea to form a supergroup originated in 2000 on the Tattoo the Earth tour, although plans were constantly put on hold due to scheduling conflicts. The summer of 2006 allowed the band to take the project seriously and record its first album. Recorded at Chasin' Jason studio in Dimebag Darrell's backyard, a self-titled album was completed in roughly one month. Released on April 10, 2007, the album entered the "Billboard" 200 at number 9, selling 45,000 copies. AllMusic reviewer William Ruhlmann stated the album is "a competent example of its genre" awarding the album three and a half stars., Industrial rock is a musical genre that fuses industrial music and specific rock subgenres, not to be confused with industrial metal. The early fusions of industrial music and rock were practiced by a handful of post-punk groups, including Chrome, Killing Joke, Swans, Foetus, and Big Black. Artists such as Nine Inch Nails and Marilyn Manson propelled the genre to mainstream status., New Orleans (or ) is a major United States port and the largest city and metropolitan area in the state of Louisiana. The population of the city was 343,829 as of the 2010 U.S. Census. The New Orleans metropolitan area (New OrleansMetairieKenner Metropolitan Statistical Area) had a population of 1,167,764 in 2010 and was the 46th largest in the United States. The New OrleansMetairieBogalusa Combined Statistical Area, a larger trading area, had a 2010 population of 1,452,502., Houston is the most populous city in Texas and the fourth-most populous city in the United States after Chicago, located in Southeast Texas near the Gulf of Mexico. With a census-estimated 2014 population of 2.239 million within an area of , it also is the largest city in the Southern United States, as well as the seat of Harris County. It is the principal city of HoustonThe WoodlandsSugar Land, which is the fifth-most populated metropolitan area in the United States of America., The 2010 United States Census, (known as "Census 2010"), is the twenty-third and currently most recent United States national census. National Census Day, the reference day used for the census, was April 1, 2010. As part of a drive to increase the count's accuracy, 635,000 temporary enumerators were hired. The population of the United States was counted as 308,745,538, a 9.7% increase from the 2000 Census., A county seat is an administrative center, seat of government, or capital city of a county or civil parish. The term is used in the United States, Canada, Romania, China and Taiwan. In the United Kingdom and Ireland, county towns have a similar function., Subject: the great southern trendkill, Relation: genre, Options: (A) album (B) baroque (C) blues (D) country (E) economy (F) entertainment (G) fashion (H) film score (I) glam metal (J) glam rock (K) government (L) groove (M) groove metal (N) heavy metal (O) history (P) industrial metal (Q) industrial rock (R) japanese (S) jazz (T) magazine (U) march (V) music (W) musical (X) percussion (Y) pop (Z) reference ([) renaissance (\) rock (]) soundtrack (^) united states of america (_) urban (`) war (a) western

Example Input: 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

Example Input: Context: The ampere (SI unit symbol: A), often shortened to "amp", is the SI unit of electric current (dimension symbol: I) and is one of the seven SI base units. It is named after André-Marie Ampère (17751836), French mathematician and physicist, considered the father of electrodynamics., The coulomb (unit symbol: C) is the International System of Units (SI) unit of electric charge. It is the charge (symbol: "Q" or "q") transported by a constant current of one ampere in one second: , The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force. The volt is named in honour of the Italian physicist Alessandro Volta (17451827), who invented the voltaic pile, possibly the first chemical battery., An electric potential (also called the "electric field potential" or the "electrostatic potential") is the amount of electric potential energy that a unitary point electric charge would have if located at any point in space, and is equal to the work done by an external agent in carrying a unit of positive charge from the arbitrarily chosen reference point (usually infinity) to that point without any acceleration. , The elementary charge, usually denoted as or sometimes , is the electric charge carried by a single proton, or equivalently, the magnitude of the electric charge carried by a single electron, which has charge . This elementary charge is a fundamental physical constant. To avoid confusion over its sign, "e" is sometimes called the elementary positive charge. This charge has a measured value of approximately or in cgs units, ., The electron is a subatomic particle, symbol or , with a negative elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron has a mass that is approximately 1/1836 that of the proton. Quantum mechanical properties of the electron include an intrinsic angular momentum (spin) of a half-integer value, expressed in units of the reduced Planck constant, "". As it is a fermion, no two electrons can occupy the same quantum state, in accordance with the Pauli exclusion principle. Like all matter, electrons have properties of both particles and waves: they can collide with other particles and can be diffracted like light. The wave properties of electrons are easier to observe with experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a larger De Broglie wavelength for a given energy., Alessandro Giuseppe Antonio Anastasio Volta (18 February 1745  5 March 1827) was an Italian physicist, chemist, and a pioneer of electricity and power, who is credited as the inventor of the electrical battery and the discoverer of methane. He invented the Voltaic pile in 1799, and reported the results of his experiments in 1800 in a two-part letter to the President of the Royal Society. With this invention Volta proved that electricity could be generated chemically and debunked the prevalent theory that electricity was generated solely by living beings. Volta's invention sparked a great amount of scientific excitement and led others to conduct similar experiments which eventually led to the development of the field of electrochemistry., Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charges: positive and negative. Like charges repel and unlike attract. An object is negatively charged if it has an excess of electrons, and is otherwise positively charged or uncharged. The SI derived unit of electric charge is the coulomb (C). In electrical engineering, it is also common to use the ampere-hour (Ah), and, in chemistry, it is common to use the elementary charge ("e") as a unit. The symbol "Q" often denotes charge. Early knowledge of how charged substances interact is now called classical electrodynamics, and is still accurate for problems that don't require consideration of quantum effects., Electromotive force, also called emf (denoted formula_1 and measured in volts), is the voltage developed by any source of electrical energy such as a battery or dynamo. It is generally defined as the electrical potential for a source in a circuit. A device that supplies electrical energy is called electromotive force or emf. Emfs convert chemical, mechanical, and other forms of energy into electrical energy. The product of such a device is also known as emf., An electric field is a vector field that associates to each point in space the Coulomb force that would be experienced per unit of electric charge, by an infinitesimal test charge at that point. Electric fields converge and diverge at electric charges and can be induced by time-varying magnetic fields. The electric field combines with the magnetic field to form the electromagnetic field., Voltage, electric potential difference, electric pressure or electric tension (formally denoted or , but more often simply as "V" or "U", for instance in the context of Ohm's or Kirchhoff's laws) is the difference in electric potential energy between two points per unit electric charge. The voltage between two points is equal to the work done per unit of charge against a static electric field to move the test charge between two points and is measured in units of "volts" (a joule per coulomb)., Chemistry is a branch of physical science that studies the composition, structure, properties and change of matter. Chemistry includes topics such as the properties of individual atoms, how atoms form chemical bonds to create chemical compounds, the interactions of substances through intermolecular forces that give matter its general properties, and the interactions between substances through chemical reactions to form different substances., In physics and electrical engineering, a conductor is an object or type of material that allows the flow of an electrical current in one or more directions. A metal wire is a common electrical conductor. Electrical current is generated by the flow of negatively charged electrons, positively charged holes, and positive or negative ions in some cases. , A capacitor is a passive two-terminal electrical component that stores electrical energy in an electric field. The effect of a capacitor is known as capacitance. While capacitance exists between any two electrical conductors of a circuit in sufficiently close proximity, a capacitor is specifically designed to provide and enhance this effect for a variety of practical applications by consideration of size, shape, and positioning of closely spaced conductors, and the intervening dielectric material. A capacitor was therefore historically first known as an electric condenser., Electric potential energy, or electrostatic potential energy, is a potential energy (measured in joules) that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system. An "object" may have electric potential energy by virtue of two key elements: its own electric charge and its relative position to other electrically charged "objects"., The joule, symbol J, is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre (1 newton metre or N·m). It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (18181889)., The voltaic pile was the first electrical battery that could continuously provide an electric current to a circuit. It was invented by Alessandro Volta, who published his experiments in 1799. The voltaic pile then enabled a rapid series of discoveries including the electrical decomposition (electrolysis) of water into oxygen and hydrogen by William Nicholson and Anthony Carlisle (1800) and the discovery or isolation of the chemical elements sodium (1807), potassium (1807), calcium (1808), boron (1808), barium (1808), strontium (1808), and magnesium (1808) by Humphry Davy., Capacitance is the ability of a body to store an electrical charge . A material with a large capacitance holds more electric charge at a given voltage , than one with low capacitance . Any object that can be electrically charged exhibits capacitance , however the concept is particularly important for understanding the operations of the capacitor , one of the three fundamental electronic components ( along with resistors and inductors ) . The SI unit of capacitance is the farad ( symbol : F ) , named after the English physicist Michael Faraday . A 1 farad capacitor , when charged with 1 coulomb of electrical charge , has a potential difference of 1 volt between its plates ., In the classical physics observed in everyday life, if something has mass and takes up space, it is said to be composed of matter; this includes atoms (and thus molecules) and anything made up of these, but not other energy phenomena or waves such as light or sound. More generally, however, in (modern) physics, matter is not a fundamental concept because a universal definition of it is elusive: elementary constituents of atoms may not take up space individually, and massless particles may be composed to form objects that have mass (even when at rest)., The ohm (symbol: ) is the SI derived unit of electrical resistance, named after German physicist Georg Simon Ohm. Although several empirically derived standard units for expressing electrical resistance were developed in connection with early telegraphy practice, the British Association for the Advancement of Science proposed a unit derived from existing units of mass, length and time and of a convenient size for practical work as early as 1861. The definition of the ohm was revised several times. Today the definition of the ohm is expressed from the quantum Hall effect., In physics, potential energy is energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. 
Common types include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The unit for energy in the International System of Units (SI) is the joule, which has the symbol "J"., Subject: capacitance, Relation: facet_of, Options: (A) electric charge (B) electrical engineering (C) electricity (D) english (E) family (F) french (G) honour (H) international system of units (I) life (J) product (K) science (L) sound (M) test (N) thought (O) water
