EDM is generally produced for playback by disc jockeys (DJs) who create seamless selections of tracks, called a mix, by segueing from one recording to another. EDM producers also perform their music live in a concert or festival setting in what is sometimes called a live PA. In the United Kingdom and in continental Europe, EDM is more commonly called 'dance music' or simply 'dance'. , The Brit Awards (sometimes stylised as the BRIT Awards; often simply called the Brits) are the British Phonographic Industry's annual pop music awards. The name was originally a shortened form of "British", "Britain" or "Britannia" (in the early days the awards were sponsored by Britannia Music Club), but subsequently became a backronym for British Record Industry Trusts Show. In addition, an equivalent awards ceremony for classical music, called the Classic Brit Awards, is held each May. Robbie Williams holds the record for the most Brit Awards, 13 as a solo artist and another five as part of Take That. , Tech house is a subgenre of house music that mixes elements of techno with house. The term "tech house" developed as a shorthand record store name for a category of electronic dance music that combined musical aspects of techno, such as "rugged basslines" and "steely beats," with the harmonies and grooves of progressive house. The music originally had a clean and minimal production style that was associated with techno from Detroit and the UK. In the mid to late 1990s a scene developed in England around club nights such as The Drop run by Mr.C & Plink Plonk, Heart & Soul, and Wiggle run by Terry Francis and Nathan Coles. Other DJs and artists associated with the sound at that time included Charles Webster, Bushwacka!, Cuartero, Dave Angel, Herbert, Funk D'Void, Ian O'Brien, Derrick Carter, and Stacey Pullen. By the late 90's London nightclub The End, owned by the former Shamen rapper Richard West (Mr C) and Layo Paskin, was considered the home of tech house in the UK. Tech house tracks are typically between 610 minutes in length., England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west.

The group's music style is pop, however throughout their career their management have experimented with dance-pop and electropop. To create this music, Ina Wroldsen, Steve Mac and Quiz & Larossi have been heavily involved., Pop music is a genre of popular music that originated in its modern form in the Western world as a softer alternative to rock and roll. The terms "popular music" and "pop music" are often used interchangeably, although the former describes all music that is popular and includes many styles. "Pop" and "rock" were synonymous terms until the late 1960s, when they were increasingly used in opposition from each other., Nicola Maria Roberts (born 5 October 1985) is an English recording artist, fashion designer, and songwriter. After auditioning and successfully completing the reality television series and competition "Popstars The Rivals", Roberts became part of girl-group Girls Aloud.

Example Input: Context: John Graham Mellor (21 August 1952  22 December 2002), known by his stage name Joe Strummer, was a British musician, singer, actor and songwriter who was the co-founder, lyricist, rhythm guitarist and lead vocalist of the Clash, a punk rock band that was formed in 1976 as part of the original wave of British punk. Their music also incorporated elements of reggae, ska, dub, funk, rap, and rockabilly. The Clash were one of the most prominent of the emerging bands in the UK punk rock scene, with their second album, "Give 'Em Enough Rope" (1978) reaching number 2 on the UK charts. Soon after, they began achieving success in the US, starting with "London Calling" (1979), and peaking with 1982's "Combat Rock", reaching number 7 on the US charts and being certified 2× platinum there. The Clash's politicised lyrics, musical experimentation, and rebellious attitude had a far-reaching influence on rock, and alternative rock in particular., A record producer or music producer oversees and manages the sound recording and production of a band or performer's music, which may range from recording one song to recording a lengthy concept album. A producer has many roles during the recording process. The roles of a producer vary. He or she may gather musical ideas for the project, collaborate with the artists to select cover tunes or original songs by the artist/group, work with artists and help them to improve their songs, lyrics or arrangements. , Funk is a music genre that originated in the mid- 1960s when African American musicians created a rhythmic, danceable new form of music through a mixture of soul music, jazz, and rhythm and blues (R&B). Funk de-emphasizes melody and chord progressions used in other related genres and brings a strong rhythmic groove of a bass line played by an electric bassist and a drum part played by a drummer to the foreground. Funk songs are often based on an extended vamp on a single chord, distinguishing them from R&B and soul songs, which are built on complex chord progressions. Funk uses the same richly-colored extended chords found in bebop jazz, such as minor chords with added sevenths and elevenths, or dominant seventh chords with altered ninths., 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.", Scott Shields ( born 26 November 1969 , Glasgow ) is a Scottish musician and record producer , best known as a member of Joe Strummer 's backing band The Mescaleros ., 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., Punk rock (or simply "punk") is a rock music genre that developed in the early to mid 1970s in the United States, United Kingdom, and Australia. Rooted in 1960s garage rock and other forms of what is now known as "proto-punk" music, punk rock bands rejected perceived excesses of mainstream 1970s rock. Punk bands typically use short or fast-paced songs, with hard-edged melodies and singing styles, stripped-down instrumentation, and often political, anti-establishment lyrics. Punk embraces a DIY ethic; many bands self-produce recordings and distribute them through informal channels., A song, most broadly, is a single (and often standalone) work of music that is typically intended to be sung by the human voice with distinct and fixed pitches and patterns using sound and silence and a variety of forms that often include the repetition of sections. Written words created specifically for music or for which music is specifically created, are called lyrics. If a pre-existing poem is set to composed music in classical music it is an art song. Songs that are sung on repeated pitches without distinct contours and patterns that rise and fall are called chants. Songs in a simple style that are learned informally are often referred to as folk songs. Songs that are composed for professional singers who sell their recordings or live shows to the mass market are called popular songs. These songs, which have broad appeal, are often composed by professional songwriters, composers and lyricists. Art songs are composed by trained classical composers for concert or recital performances. Songs are performed live and recorded on audio or video (or in some, cases, a song may be performed live and simultaneously recorded). Songs may also appear in plays, musical theatre, stage shows of any form, and within operas., Ska (Jamaican ) is a music genre that originated in Jamaica in the late 1950s and was the precursor to rocksteady and reggae. Ska combined elements of Caribbean mento and calypso with American jazz and rhythm and blues. It is characterized by a walking bass line accented with rhythms on the off-beat. Ska developed in Jamaica in the 1960s when Prince Buster, Clement "Coxsone" Dodd, and Duke Reid formed sound systems to play American rhythm & blues and then began recording their own songs. Some suggest ska dates to earlier times, however. In the early 1960s, ska was the dominant music genre of Jamaica and was popular with British mods. Later it became popular with many skinheads., The Clash were an English punk rock band that formed in 1976 as part of the original wave of British punk. Along with punk, their music incorporated elements of reggae, dub, funk, ska and rockabilly. For most of their recording career the Clash consisted of Joe Strummer (lead vocals, rhythm guitar), Mick Jones (lead guitar, lead vocals), Paul Simonon (bass guitar, vocals) and Nicky "Topper" Headon (drums, percussion). Headon left the group in 1982, and internal friction led to Jones's departure the following year. The group continued with new members, but finally disbanded in early 1986., Subject: scott shields , Relation: instrument, Options: (A) bass (B) bass guitar (C) guitar (D) human voice (E) percussion instrument (F) singing

Example Input: Context: In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon, and thus are group 14 hydrides. Hydrocarbons from which one hydrogen atom has been removed are functional groups, called hydrocarbyls.
Aromatic hydrocarbons (arenes), alkanes, alkenes, cycloalkanes and alkyne-based compounds are different types of hydrocarbons., Nitrogen is a chemical element with symbol N and atomic number 7. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772. Although Carl Wilhelm Scheele and Henry Cavendish had independently done so at about the same time, Rutherford is generally accorded the credit because his work was published first. The name "nitrogen" was suggested by Jean-Antoine-Claude Chaptal in 1790, when it was found that nitrogen was present in nitric acid and nitrates; this name derives from the Greek roots  "nitre" and - "to form". Antoine Lavoisier suggested instead the name "azote", from the Greek  "no life", as it is an asphyxiant gas; his name is instead used in many languages, such as French, Russian, and Turkish, and appears in the English names of some nitrogen compounds such as hydrazine, azides and azo compounds., Carbon dioxide (chemical formula CO) is a colorless and odorless gas that is vital to life on Earth. This naturally occurring chemical compound is made up of a carbon atom covalently double bonded to two oxygen atoms. Carbon dioxide exists in Earth's atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume. Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater. It is present in deposits of petroleum and natural gas., Helium is a chemical element with symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table.

The relative abundance of methane on Earth makes it an attractive fuel, though capturing and storing it poses challenges due to its gaseous state under normal conditions for temperature and pressure., Hydrogen sulfide is the chemical compound with the formula . It is a colorless gas with the characteristic foul odor of rotten eggs. It is very poisonous, corrosive, and flammable., A combined statistical area (CSA) is composed of adjacent metropolitan (MSA) and micropolitan statistical areas (µSA) in the United States and Puerto Rico that can demonstrate economic or social linkage. The United States Office of Management and Budget defines a CSA as consisting of various combinations of adjacent metropolitan and micropolitan areas with economic ties measured by commuting patterns. These areas that combine retain their own designations as metropolitan or micropolitan statistical areas within the larger combined statistical area., Oklahoma City is the capital and largest city of the state of Oklahoma. The county seat of Oklahoma County, the city ranks 27th among United States cities in population. The population grew following the 2010 Census, with the population estimated to have increased to 631,346 as of July 2015. As of 2015, the Oklahoma City metropolitan area had a population of 1,358,452, and the Oklahoma City-Shawnee Combined Statistical Area had a population of 1,459,758 (Chamber of Commerce) residents, making it Oklahoma's largest metropolitan area., Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture would contain a variety of pure gases much like the air. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colorless gas invisible to the human observer. The interaction of gas particles in the presence of electric and gravitational fields are considered negligible as indicated by the constant velocity vectors in the image. One type of commonly known gas is steam., Ethane (or ) is an organic chemical compound with chemical formula CH. At standard temperature and pressure, ethane is a colorless, odorless gas. Like many hydrocarbons, ethane is isolated on an industrial scale from natural gas and as a petrochemical byproduct of petroleum refining. Its chief use is as feedstock for ethylene production., Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium. It is formed when layers of decomposing plant and animal matter are exposed to intense heat and pressure under the surface of the Earth over millions of years. The energy that the plants originally obtained from the sun is stored in the form of chemical bonds in the gas., Subject: sandridge energy, Relation: industry, Options: (A) chemistry (B) commerce (C) gas (D) human (E) management (F) natural gas (G) petroleum
