Example Input: Context: The British Broadcasting Corporation (BBC) is a British public service broadcaster. It is headquartered at Broadcasting House in London, is the world's oldest national broadcasting organisation, and is the largest broadcaster in the world by number of employees, with over 20,950 staff in total, of whom 16,672 are in public sector broadcasting; including part-time, flexible as well as fixed contract staff, the total number is 35,402., Doctor Who is a British science-fiction television programme produced by the BBC since 1963. The programme depicts the adventures of a Time Lord called "The Doctor", an extraterrestrial being from the planet Gallifrey. He explores the universe in a time-travelling space ship called the TARDIS. Its exterior appears as a blue British police box, which was a common sight in Britain in 1963 when the series first aired. Accompanied by a number of companions, the Doctor combats a variety of foes, while working to save civilisations and help people in need., A Very Peculiar Practice is a BBC comedy-drama series, which ran for two series in 1986 and 1988. The series was a surreal black comedy, set in the health centre of a British university. The two series were followed by a 90-minute made-for-television film following some of the characters to a new setting in Poland., A police box, used in the United Kingdom throughout the 20th century, is a public telephone kiosk or callbox for the use of members of the police, or for members of the public to contact the police. Unlike an ordinary callbox, its telephone was located behind a hinged door so it could be used from the outside, and the interior of the box was, in effect, a miniature police station for use by police officers to read and fill in reports, take meal breaks and even temporarily hold prisoners until the arrival of transport., A television program is a segment of content intended for broadcast on over-the-air, cable television, or Internet television, other than a commercial, trailer, or any other segment of content not serving as attraction for viewership. It may be a single production, or more commonly, a series of related productions (also called a television series or a television show)., Hampstead (or ), commonly known as Hampstead Village, is an area of London, England, northwest of Charing Cross. Part of the London Borough of Camden, it is known for its intellectual, liberal, artistic, musical and literary associations and for Hampstead Heath, a large, hilly expanse of parkland. It has some of the most expensive housing in the London area. The village of Hampstead has more millionaires within its boundaries than any other area of the United Kingdom., David Troughton (born 9 June 1950, Hampstead, London) is an English actor, known for his Shakespearean roles on the British stage and for his many roles on British television, including Dr Bob Buzzard in "A Very Peculiar Practice" and Ricky Hansen in "New Tricks"., The TARDIS (Time And Relative Dimension In Space) is a fictional time machine and spacecraft that appears in the British science fiction television programme "Doctor Who" and its various spin-offs., Michael Troughton ( born 2 March 1955 ) is an English actor , writer , and teacher . He is the son of actor Patrick Troughton ( known as the Second Doctor in Doctor Who in the 1960s ) and the younger brother of David Troughton ., New Tricks is a British procedural comedy-drama that follows the work of the fictional Unsolved Crime and Open Case Squad (UCOS) of the Metropolitan Police Service. Originally led by Detective Superintendent Sandra Pullman, it is made up of retired police officers recruited to reinvestigate unsolved crimes. There have been cast changes, but the squad always consists of three men with a female boss. The series title is taken from the proverb "You can't teach an old dog new tricks". In February 2015, BBC One announced the show would end after series 12, which comprises 10 episodes., The Second Doctor is an incarnation of the Doctor, the protagonist of the BBC science fiction television series "Doctor Who". He was portrayed by character actor Patrick Troughton., The Time Lords are a fictional, ancient extraterrestrial people in the British science fiction television series "Doctor Who", of which the series' protagonist, the Doctor, is a member. Time Lords are so named for their command of time travel technology and their non-linear perception of time. Originally they were described as a powerful and wise race from the planet Gallifrey, from which the Doctor was a renegade; details beyond this were very limited for the first decade of the series. They later became integral to many episodes and stories as their role in the fictional universe developed. For the first eight years after the series resumed in 2005, the Time Lords were said to have been destroyed at some point between the original series' cancellation in 1989 and the show's revival during the fictional Last Great Time War. In 2013, the 50th anniversary special "The Day of the Doctor" concerned this supposed destruction and their eventual survival., Gallifrey (or ) is a planet in the long-running British science fiction television series "Doctor Who". It is the original home world of the Doctor, The Master, and The Rani, as well as other Time Lords that have been seen in the show. It was located in a binary star system within the constellation of Kasterborous, at "galactic coordinates ten-zero-eleven-zero-zero by zero-two from galactic zero centre"., Patrick George Troughton (25 March 1920  28 March 1987) was an English actor. He was classically trained for the stage but became most widely known for his roles in television and film. His work included appearances in several fantasy, science fiction and horror films, but he became best known for his role as the second incarnation of the Doctor in the long-running British science-fiction television series "Doctor Who", which he played from 1966 to 1969; he reprised the role in 1973, 1983 and 1985., A character actor or character actress is a supporting actor who plays unusual, interesting, or eccentric characters. The term, often contrasted with that of leading actor, is somewhat abstract and open to interpretation. In a literal sense, all actors can be considered character actors since they all play "characters", but in the usual sense it is an actor who plays a distinctive and important supporting role. , Subject: michael troughton, Relation: place_of_birth, Options: (A) box (B) camden (C) drama (D) gallifrey (E) george (F) hampstead (G) hampstead heath (H) home (I) london (J) london borough (K) london borough of camden (L) made (M) march (N) of (O) pullman (P) time (Q) united kingdom (R) wise

Example Input: Context: The Northern Territory (abbreviated as NT) is a federal Australian territory in the central and central northern regions of Australia. It shares borders with Western Australia to the west (129th meridian east), South Australia to the south (26th parallel south), and Queensland to the east (138th meridian east). To the north, the territory is bordered by the Timor Sea, the Arafura Sea and the Gulf of Carpentaria. Despite its large areaover , making it the third largest Australian federal divisionit is sparsely populated. The Northern Territory's population of 244,000 (2016) makes it the least populous of Australia's eight major states and territories, having fewer than half as many people as Tasmania., A sea is a large body of salt water that is surrounded in whole or in part by land. More broadly, "the sea" is the interconnected system of Earth's salty, oceanic watersconsidered as one global ocean or as several principal oceanic divisions. The sea moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. Although the sea has been traveled and explored since prehistory, the modern scientific study of the seaoceanographydates broadly to the British "Challenger" expedition of the 1870s. The sea is conventionally divided into up to five large oceanic sectionsincluding the International Hydrographic Organization's four named oceans (the Atlantic, Pacific, Indian, and Arctic) and the Southern Ocean; smaller, second-order sections, such as the Mediterranean, are known as "seas"., A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague., The Meda River is a river in the Kimberley of Western Australia . The river is formed when the Lennard River splits into two channels just north of Mount Marmion , the other channel being the May River . Continuing to flow westward the river eventually discharges into Stokes Bay , King Sound which is north - east of Derby . The river was named in 1881 by a pioneer of the area , George Julius Brockman during an expedition in the Kimberley area . The river is named after HMS Meda , an Admiralty surveying vessel that charted the coastline in the area including the river mouth in 1880 . The traditional owners of the areas around the river are the Ongkarango peoples . The Meda has three tributaries ; The Lennard River , May River and Hawkstone Creek ., The Indian Ocean is the third largest of the world's oceanic divisions, covering (approximately 20% of the water on the Earth's surface). It is bounded by Asia on the north, on the west by Africa, on the east by Australia, and on the south by the Southern Ocean or, depending on definition, by Antarctica. It is named after the country of India. The Indian Ocean is known as "Ratnkara", ""the mine of gems"" in ancient Sanskrit literature, and as "Hind Mahsgar", ""the great Indian sea"", in Hindi., The Great Australian Bight is a large oceanic bight, or open bay, off the central and western portions of the southern coastline of mainland Australia., The Southern Ocean, also known as the Antarctic Ocean or the Austral Ocean, comprises the southernmost waters of the World Ocean, generally taken to be south of 60° S latitude and encircling Antarctica. As such, it is regarded as the fourth-largest of the five principal oceanic divisions: smaller than the Pacific, Atlantic, and Indian Oceans but larger than the Arctic Ocean. This ocean zone is where cold, northward flowing waters from the Antarctic mix with warmer subantarctic waters., Western Australia (abbreviated as WA) is a state occupying the entire western third of Australia. It is bounded by the Indian Ocean to the north and west, the Great Australian Bight and Southern Ocean to the south, the Northern Territory to the north-east and South Australia to the south-east. Western Australia is Australia's largest state with a total land area of 2,529,875 square kilometres (976,790 sq mi), and the second-largest country subdivision in the world  however, a significant part of it is sparsely populated. The state has about 2.6 million inhabitants, around 11% of the national total. 92% of the population lives in the south-west corner of the state., An ocean (the sea of classical antiquity) is a body of saline water that composes much of a planet's hydrosphere. On Earth, an ocean is one of the major conventional divisions of the World Ocean, which covers almost 71% of its surface. These are, in descending order by area, the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic Oceans. The word "sea" is often used interchangeably with "ocean" in American English but, strictly speaking, a sea is a body of saline water (generally a division of the world ocean) partly or fully enclosed by land., Subject: meda river, Relation: mouth_of_the_watercourse, Options: (A) arafura sea (B) arctic ocean (C) great australian bight (D) indian ocean (E) sea (F) southern ocean (G) timor sea
Example Output: indian ocean

Example Input: Context: Stucco or render is a material made of aggregates, a binder, and water. Stucco is applied wet and hardens to a very dense solid. It is used as decorative coating for walls and ceilings and as a sculptural and artistic material in architecture. Stucco may be used to cover less visually appealing construction materials such as metal, concrete, cinder block, or clay brick and adobe., Road surface or pavement is the durable surface material laid down on an area intended to sustain vehicular or foot traffic, such as a road or walkway. In the past, gravel road surfaces, cobblestone and granite setts were extensively used, but these surfaces have mostly been replaced by asphalt or concrete laid on a compacted base course. Road surfaces are frequently marked to guide traffic. Today, permeable paving methods are beginning to be used for low-impact roadways and walkways., In geometry, an octagon (from the Greek  "oktágnon", "eight angles") is an eight-sided polygon or 8-gon., A cement is a binder, a substance used in construction that sets and hardens and can bind other materials together. The most important types of cement are used as a component in the production of mortar in masonry, and of concrete, which is a combination of cement and an aggregate to form a strong building material., A chamfer is a transitional edge between two faces of an object. It can also be known as a bevel but connotes more often cutting and is more often 45° with respect to the two adjoining faces. If the un-chamfered intersection of the adjoining faces would otherwise form a right angle, 90° as is most common, the chamfer will typically be uniform and pitched at 45° . A fully chamfered square interior would thus be octagonal. (By contrast, a fillet is the rounding-off of an interior corner, and a rounding of an exterior corner is called a "round" or a "radius"), A bevelled edge (UK) or beveled edge (US) refers to an edge of a structure that is not perpendicular to the faces of the piece. The words bevel and chamfer overlap in usage; in general usage they are often interchanged, while in technical usage they may sometimes be differentiated as shown in the image at right. A bevel is typically used to soften the edge of a piece for the sake of safety, wear resistance, or aesthetics; or to facilitate mating with another piece., Screed has three meanings in building construction. 1) a flat board (screed board, floating screed) or a purpose-made aluminium tool used to smooth and true materials like concrete, stucco and plaster after it has been placed on a surface or to assist in flattening; 2) a strip of plaster or wood applied to a surface to act as a guide for a screed tool (screed rail, screed strip, screed batten); 3) the material itself which has been flattened with a screed (screed coat). In the UK, "screed" has also come to describe a thin, top layer of material (traditionally sand and cement), poured in site on top of the structural concrete or insulation, on top of which other finishing materials can be applied, or it can be left bare to achieve a raw effect. It is becoming more common to use "self-leveling" poured screeds which use materials other than cement as their binder., Aluminium or aluminum (in North American English) is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic, ductile metal. Aluminium is the third most abundant element in the Earth's crust (after oxygen and silicon) and its most abundant metal. Aluminium makes up about 8% of the crust by mass, though it is less common in the mantle below. Aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals. The chief ore of aluminium is bauxite., Batten has multiple meanings in construction and shipbuilding but is generally a strip of solid material, historically made from wood but can also be made from plastic, metal, or fiberglass. In a sense used in flooring a batten may be relatively large, up to thick by wide and more than long., Portland cement is the most common type of cement in general use around the world, used as a basic ingredient of concrete, mortar, stucco, and most non-speciality grout. It was developed from other types of hydraulic lime in England in the mid 19th century and usually originates from limestone. It is a fine powder produced by heating materials in a kiln to form what is called clinker, grinding the clinker, and adding small amounts of other materials. Several types of Portland cement are available, with the most common being called ordinary Portland cement (OPC) which is grey in color, but a white Portland cement is also available., Asphalt (, occasionally ), also known as bitumen is a sticky, black and highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product; it is a substance classed as a pitch. Until the 20th century, the term asphaltum was also used. The word is derived from the Ancient Greek  "ásphaltos"., A craft is a pastime or a profession that requires particular skills and knowledge of skilled work. In a historical sense, particularly as pertinent to the Middle Ages and earlier, the term is usually applied to people occupied in small-scale production of goods, or their maintenance, for example by tinkers. The traditional terms "craftsman" and "craftswoman" are nowadays often replaced by "artisan" and rarely by "craftsperson" (craftspeople)., A concrete finisher , is a tradesman who works with concrete . The job entails placing , finishing , protecting and repairing concrete in engineering and construction projects . Concrete finishers are often responsible for setting the concrete forms , ensuring they have the correct depth and pitch . Concrete finishers place the concrete either directly from the concrete wagon chute , concrete pump , concrete skip or wheelbarrow . They spread the concrete using shovels and rakes , sometimes using a straightedge back and forth across the top of the forms to `` screed , '' or level , the freshly placed concrete . After levelling the concrete , they smooth the surface using either a hand trowel ) , a long handed `` bull float '' or powered floats . After the concrete has been leveled and floated , concrete finishers press an edger between the forms and the concrete to chamfer the edges so that they are less likely to chip . Broom and stamp finishes are a couple of different finished products for outdoor concrete after the trowel - finish is complete . The broom finish is used to prevent slipping on the concrete , and the stamp finish is used for looks ., Concrete is a composite material composed of coarse aggregate bonded together with a fluid cement that hardens over time. Most concretes used are lime-based concretes such as Portland cement concrete or concretes made with other hydraulic cements, such as ciment fondu. However, asphalt concrete, which is frequently used for road surfaces, is also a type of concrete, where the cement material is bitumen, and polymer concretes are sometimes used where the cementing material is a polymer., A composite material (also called a composition material or shortened to composite, which is the common name) is a material made from two or more constituent materials with significantly different physical or chemical properties that, when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure. The new material may be preferred for many reasons: common examples include materials which are stronger, lighter, or less expensive when compared to traditional materials. More recently, researchers have also begun to actively include sensing, actuation, computation and communication into composites, which are known as Robotic Materials., A tradesman, tradesperson or skilled tradesman refers to a worker that specializes in a particular trade or craft requiring skill . , Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac or bitumen macadam in Great Britain and Ireland) is a composite material commonly used to surface roads, parking lots, and airports. It consists of mineral aggregate bound together with asphalt, laid in layers, and compacted. The process was refined and enhanced by Belgian inventor and U.S. immigrant Edward de Smedt. It is increasingly being used as the core of embankment dams., Polymer concretes are a type of concrete that use polymers to replace lime-type cements as a binder. In some cases the polymer is used in addition to portland cement to form Polymer Cement Concrete (PCC) or Polymer Modified Concrete (PMC). Polymers in concrete have been overseen by Committee 548 of the American Concrete Institute since 1971., Subject: concrete finisher, Relation: instance_of, Options: (A) angle (B) architecture (C) area (D) asphalt (E) binder (F) chemical (G) chemical element (H) combination (I) committee (J) common name (K) communication (L) component (M) composite material (N) concrete (O) construction (P) craft (Q) eight (R) england (S) fluid (T) group (U) ingredient (V) liquid (W) masonry (X) mass (Y) material (Z) may ([) metal (\) mineral (]) mortar (^) object (_) pavement (`) polygon (a) polymer (b) production (c) profession (d) road (e) sense (f) shipbuilding (g) skill (h) structure (i) symbol (j) three (k) time (l) tool (m) trade (n) two (o) water (p) will
