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: Protist is an informal term for any eukaryotic organism that is not an animal, plant or fungus. The protists do not form a natural group, or clade, but are often grouped together for convenience, like algae or invertebrates. In some systems of biological classification, such as the popular 5-kingdom scheme proposed by Robert Whittaker in 1969, the protists make up a kingdom called Protista, composed of "organisms which are unicellular or unicellular-colonial and which form no tissues.", The metamonads are a large group of flagellate amitochondriate protozoa . Their composition is not entirely settled , but they include the retortamonads , diplomonads , and possibly the parabasalids and oxymonads as well . These four groups are all anaerobic , occurring mostly as symbiotes of animals ., A flagellate is a cell or organism with one or more whip-like organelles called flagella. The word "flagellate" also describes a particular construction (or level of organization) characteristic of many protists (eukaryotic organisms) and their means of motion. The term presently does not imply any specific relationship or classification of the organisms that possess flagellae. However, the term "flagellate" is included in other terms (such as "dinoflagellate" and "choanoflagellata") which are more formally characterized., The retortamonads are a small group of flagellates, most commonly found in the intestines of animals as commensals, although a free-living species called the "Chilomastix cuspidata" exists. They are grouped under the taxon, Archezoa. They are usually around 5-20 m in length, and all of their small subunit ribosomal RNA gene sequences are very similar to each other. There are two genera: "Retortamonas" with two flagella, and "Chilomastix" with four. In both cases there are four basal bodies anterior to a prominent feeding groove, and one flagellum is directed back through the cell, emerging from the groove., The dinoflagellates (Greek  "dinos" "whirling" and Latin "flagellum" "whip, scourge") are a large group of flagellate protists that constitute the phylum Dinoflagellata. Most are marine plankton, but they are common in freshwater habitats, as well. Their populations are distributed depending on temperature, salinity, or depth. Many dinoflagellates are known to be photosynthetic, but a large fraction of these are in fact mixotrophic, combining photosynthesis with ingestion of prey (phagotrophy). In terms of number of species, dinoflagellates form one of the largest groups of marine eukaryotes, although this group is substantially smaller than the diatoms. Some species are endosymbionts of marine animals and play an important part in the biology of coral reefs. Other dinoflagellates are unpigmented predators on other protozoa, and a few forms are parasitic (see for example "Oodinium", "Pfiesteria"). Some dinoflagellates produce resting stages, called dinoflagellate cysts or dinocysts, as part of their lifecycles., Subject: metamonad, Relation: instance_of, Options: (A) animal (B) biology (C) cell (D) clade (E) classification (F) construction (G) dinos (H) group (I) organism (J) organization (K) plant (L) taxon (M) term (N) whip

Example Input: Context: A great power is a sovereign state that is recognized as having the ability and expertise to exert its influence on a global scale. Great powers characteristically possess military and economic strength, as well as diplomatic and soft power influence, which may cause middle or small powers to consider the great powers' opinions before taking actions of their own. International relations theorists have posited that great power status can be characterized into power capabilities, spatial aspects, and status dimensions., Infantry is the general branch of an army that engages in military combat on foot. As the troops who engage with the enemy in close-ranged combat, infantry units bear the largest brunt of warfare and typically suffer the greatest number of casualties during a military campaign. Historically, as the oldest branch of the combat arms, the infantry are the tip of the spear of a modern army, and continually undergo training that is typically more physically demanding and psychologically stressful than that of any other branch of the combat arms. Common representations of infantry fighting forces include the U.S. Army Infantry Branch, U.S. Marine Corps Infantry, Royal Canadian Infantry Corps, Infantry of the British Army, and the Royal Australian Corps of Infantry., In politics and military planning, a war effort refers to a coordinated mobilization of society's resourcesboth industrial and humantowards the support of a military force. Depending on the militarization of the culture, the relative size of the armed forces and the society supporting them, the style of government, and the popular support for the military objectives, such war effort can range from a small industry to complete command of society., The Treaty of Versailles was the most important of the peace treaties that brought World War I to an end. The Treaty ended the state of war between Germany and the Allied Powers. It was signed on 28 June 1919, exactly five years after the assassination of Archduke Franz Ferdinand. The other Central Powers on the German side of World War I signed separate treaties. Although the armistice, signed on 11 November 1918, ended the actual fighting, it took six months of Allied negotiations at the Paris Peace Conference to conclude the peace treaty. The treaty was registered by the Secretariat of the League of Nations on 21 October 1919., Total war is warfare that includes any and all civilian-associated resources and infrastructure as legitimate military targets, mobilizes all of the resources of society to fight the war, and gives priority to warfare over non-combatant needs. The American-English Dictionary defines total war as "war that is unrestricted in terms of the weapons used, the territory or combatants involved, or the objectives pursued, especially one in which the laws of war are disregarded.", The Luftwaffe Field Divisions (German: "Luftwaffen-Feld-Divisionen" or LwFD) were German military formations during World War II., A military alliance is an international agreement concerning national security, when the contracting parties promise to support each other in case of a crisis that has not been identified in advance. Military alliances differ from coalitions, as coalitions are formed for a crisis that are already known., The Holocaust (from the Greek ': "hólos", "whole" and "kaustós", "burnt"), also referred to as the Shoah"' (Hebrew: , "HaShoah", "the catastrophe"), was a genocide in which Adolf Hitler's Nazi Germany and its collaborators killed about six million Jews. The victims included 1.5 million children and represented about two-thirds of the nine million Jews who had resided in Europe. Some definitions of the Holocaust include the additional five million non-Jewish victims of Nazi mass murders, bringing the total to about 11 million. Killings took place throughout Nazi Germany, German-occupied territories, and territories held by allies of Nazi Germany., The 4th Luftwaffe Field Division was a German infantry formation which fought during World War II., World War I (WWI or WW1), also known as the First World War, or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history. Over nine million combatants and seven million civilians died as a result of the war (including the victims of a number of genocides), a casualty rate exacerbated by the belligerents' technological and industrial sophistication, and the tactical stalemate caused by gruelling trench warfare. It was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved., World War II (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's nationsincluding all of the great powerseventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World War II the deadliest conflict in human history., Hiroshima is perhaps best known as the first city in history to be targeted by a nuclear weapon when the United States Army Air Forces (USAAF) dropped an atomic bomb on the city (and later on Nagasaki) at 8:15 a.m. on August 6, 1945, near the end of World War II., The Wehrmacht (lit. "defence force") was the unified armed forces of Nazi Germany from 1935 to 1946. It consisted of the "Heer" (army), the "Kriegsmarine" (navy) and the "Luftwaffe" (air force). The designation "Wehrmacht" for Nazi Germany's military replaced the previously used term, "Reichswehr" (191935), and was the manifestation of Nazi Germany's efforts to rearm the nation to a greater extent than the Treaty of Versailles permitted., A spear is a pole weapon consisting of a shaft, usually of wood, with a pointed head. The head may be simply the sharpened end of the shaft itself, as is the case with fire hardened spears, or it may be made of a more durable material fastened to the shaft, such as flint, obsidian, iron, steel or bronze. The most common design for hunting or combat spears since ancient times has incorporated a metal spearhead shaped like a triangle, lozenge, or leaf. The heads of fishing spears usually feature barbs or serrated edges., The Deutsche Luftstreitkräfte (German Air Force)known before October 1916 as the Fliegertruppen des deutschen Kaiserreiches ("Imperial German Flying Corps") or simply Die Fliegertruppewas the World War I (191418) air arm of the German Army, of which it remained an integral part. In English-language sources it is usually referred to as the Imperial German Air Service, although that is not a literal translation of either name. German naval aviators serving with the "Marine-Fliegerabteilung" remained an integral part of the Imperial German Navy "(Kaiserliche Marine)". Both military branches, the army and navy, operated conventional aircraft, observation balloons and Zeppelins., The Luftwaffe was the aerial warfare branch of the combined German Wehrmacht military forces during World War II. Germany's military air arms during the First World War, the "Luftstreitkräfte" of the Army and the "Marine-Fliegerabteilung" of the Navy, had been disbanded in May 1920 as a result of the terms of the Treaty of Versailles which stated that Germany was forbidden to have any air force., Strategic bombing is a military strategy used in a total war with the goal of defeating the enemy by destroying its morale or its economic ability to produce and transport materiel to the theatres of military operations, or both. It is a systematically organized and executed attack from the air which can utilize strategic bombers, long- or medium-range missiles, or nuclear-armed fighter-bomber aircraft to attack targets deemed vital to the enemy's war-making capability., The United States dropped nuclear weapons on the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945, respectively, during the final stage of World War II. The United States had dropped the bombs with the consent of the United Kingdom as outlined in the Quebec Agreement. The two bombings, which killed at least 129,000 people, remain the only use of nuclear weapons for warfare in history., Combat arms (or fighting arms in non-American parlance) is a collective name in a system of administrative military reference to those troops within national armed forces which participate in direct tactical ground combat. In general they include units that carry or employ a weapon system such as infantry, cavalry, and artillery units. The use of multiple combat arms in mutually supporting ways is known as combined arms., During World War II, the American atomic bombings of Hiroshima and Nagasaki made Nagasaki the second and, to date, last city in the world to experience a nuclear attack., The Royal Canadian Infantry Corps is the infantry corps of the Canadian Army and includes regular and reserve force regiments., The Infantry of the British Army, part of the structure of the British Army, comprises 47 infantry battalions, from 19 regiments. Of these, 33 battalions are part of the Regular army and the remaining 14 a part of the Army Reserve. The British Army's Infantry forms a highly flexible organisation, taking on a variety of roles, including armoured, mechanised, air assault and light., Subject: 4th luftwaffe field division , Relation: part_of, Options: (A) 1946 (B) air force (C) arm (D) army (E) august (F) british army (G) canadian (H) cavalry (I) city (J) europe (K) fire (L) foot (M) german (N) german navy (O) government (P) head (Q) hebrew (R) history (S) international relations (T) japanese (U) july (V) leaf (W) may (X) military (Y) military campaign (Z) name ([) national armed forces (\) nuclear weapon (]) october (^) part (_) politics (`) reichswehr (a) society (b) sovereign state (c) stage (d) state (e) system (f) the holocaust (g) training (h) transport (i) treaty (j) triangle (k) variety (l) war (m) warfare (n) wehrmacht (o) world war i (p) world war ii
