Input: Consider Input: Context: A chain gun is a type of machine gun or autocannon that uses an external source of power to cycle the weapon rather than diverting energy from the cartridge , and does so via a continuous loop of chain similar to that used on a motorcycle or bicycle . `` Chain gun '' is a registered trademark of Alliant Techsystems Inc. for a chain - powered weapon ., The word bullet is a firearm term. A bullet is a projectile expelled from the barrel of a firearm. The term is from Middle French and originated as the diminutive of the word boulle (boullet) which means "small ball." Bullets are made of a variety of materials. They are available singly as they would be used in muzzle loading and cap and ball firearms, as part of a paper cartridge, and much more commonly as a component of metallic cartridges. Bullets are made in a large numbers of styles and constructions depending on how they will be used. Many bullets have specialized functions, such as hunting, target shooting, training, defense, and warfare. , An autocannon or automatic cannon is a large, fully automatic, rapid-fire projectile weapon that fires armour-piercing or explosive shells, as opposed to the bullet fired by a machine gun. Autocannons often have a larger calibre than a machine gun (e.g., 20 mm or greater), but are usually smaller than a field gun or other artillery. When used on its own, the word "autocannon" indicates a single-barrel weapon. When multiple rotating barrels are involved, the word "rotary" is added, and such a weapon is referred to as a "rotary autocannon." Modern autocannons are typically not single soldier-portable or stand-alone units, rather they are usually vehicle-mounted, aircraft-mounted, or boat-mounted, or even remote-operated as in some naval applications. As such, ammunition is typically fed from a belt to reduce reloading or for a faster rate of fire, but a magazine remains an option. They can use a variety of ammunition: common shells include high-explosive dual-purpose types (HEDP), any variety of armour-piercing (AP) types, such as composite rigid (APCR) or discarding sabot types (APDS)., A battle rifle is a military service rifle that fires a full-power rifle cartridge, such as 7.62×51mm NATO, 7.62×54mmR, 7.92x57mm Mauser, .303 British, or .30-06 Springfield. Compared to assault rifles and their intermediate cartridges, the higher-caliber rounds provide greater power and range, though they have greater weight and produce stronger recoil, making them less than ideal for fully automatic fire., A field gun is an artillery piece. Originally the term referred to smaller guns that could accompany a field army on the march and when in combat could be moved about the battlefield in response to changing circumstances (field artillery), as opposed to guns installed in a fort (garrison artillery/coastal artillery), or to siege cannon or mortars which were too large to be moved quickly, and would be used only in a prolonged siege., A submachine gun (SMG) is an air-cooled, magazine-fed, automatic carbine designed to fire pistol cartridges. The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun., Rate of fire is the frequency at which a specific weapon can fire or launch its projectiles. It is usually measured in rounds per minute (RPM or round/min), or rounds per second (RPS or round/s)., A machine gun is a fully automatic mounted or portable firearm, designed to fire bullets in quick succession from an ammunition belt or magazine, typically at a rate of 300 to 1800 rounds per minute. Fully automatic firearms are generally categorized as submachine guns, assault rifles, battle rifles, automatic shotguns, machine guns, or autocannons. Machine guns with multiple rotating barrels are referred to as "rotary machine guns"., An automatic shotgun is an automatic firearm that fires shotgun shells and uses some of the energy of each shot to automatically cycle the action and load a new round. It will fire repeatedly until the trigger is released or ammunition runs out. Automatic shotguns have a very limited range, but provide tremendous firepower at close range., A shotgun (also known as a scattergun, or historically as a fowling piece) is a firearm that is usually designed to be fired from the shoulder, which uses the energy of a fixed shell to fire a number of small spherical pellets called shot, or a solid projectile called a slug. Shotguns come in a wide variety of sizes, ranging from 5.5 mm (.22 inch) bore up to bore, and in a range of firearm operating mechanisms, including breech loading, single-barreled, double or combination gun, pump-action, bolt-, and lever-action, semi-automatic, and even fully automatic variants., Artillery is a class of large military weapons built to fire munitions far beyond the range and power of infantry's small arms. Early artillery development focused on the ability to breach fortifications, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility providing the largest share of an army's total firepower., An assault rifle is a selective-fire rifle that uses an intermediate cartridge and a detachable magazine. Assault rifles were first used during World War II. Though Western nations were slow to accept the assault rifle concept after World War II, by the end of the 20th century they had become the standard weapon in most of the world's armies, replacing semi-automatic rifles, battle rifles and sub-machine guns in most roles. Examples include the StG 44, AK-47 and the M16 rifle., Subject: chain gun, Relation: subclass_of, Options: (A) ability (B) action (C) ammunition (D) army (E) artillery (F) assault rifle (G) autocannon (H) battle (I) battle rifle (J) belt (K) bullet (L) cannon (M) class (N) energy (O) field gun (P) fire (Q) firearm (R) fort (S) gun (T) hunting (U) infantry (V) lighter (W) machine (X) magazine (Y) march (Z) military ([) option (\) part (]) power (^) projectile (_) rate (`) rifle (a) service (b) shooting (c) shot (d) shotgun (e) single (f) solid (g) submachine gun (h) technology (i) term (j) variety (k) vehicle (l) weapon (m) word

Input: Consider Input: Context: A duma () is a Russian assembly with advisory or legislative functions. The term comes from the Russian verb  ("dumat") meaning "to think" or "to consider". The first formally constituted duma was the State Duma introduced into the Russian Empire by Tsar Nicholas II in 1906. It was dissolved in 1917 during the Russian Revolution. Since 1993, the State Duma is the lower legislative house of the Russian Federation., Russia is not proportionately populated between the smaller western portion (almost 25%) of the country that is considered part of Europe, and the larger eastern portion (more than 75%) that is part of Asia. European Russia contains about 77% of the country's population (110,000,000 people out of about 144,000,000) in an area comprising almost 4 million km (1.54 million mi); an average of 27.5 persons per km (70 per mi). This territory makes up 38% of Europe. Its eastern border is defined by the Ural Mountains and in the south, it is defined by the border with Kazakhstan. This area includes Moscow and Saint Petersburg, the two largest cities in Russia., An upper house, sometimes called a Senate, is one of two chambers of a bicameral legislature (or one of three chambers of a tricameral legislature), the other chamber being the lower house. The house formally designated as the upper house is usually smaller, and often has more restricted power, than the lower house. Examples of upper houses in countries include the UK's House of Lords, Canada's Senate, India's Rajya Sabha, Russia's Federation Council, Ireland's Seanad, Germany's Bundesrat and the United States Senate., A country is a region that is identified as a distinct national entity in political geography. A country may be an independent sovereign state or one that is occupied by another state, as a non-sovereign or formerly sovereign political division, or a geographic region associated with sets of previously independent or differently associated people with distinct political characteristics. Regardless of the physical geography, in the modern internationally accepted legal definition as defined by the League of Nations in 1937 and reaffirmed by the United Nations in 1945, a resident of a country is subject to the independent exercise of legal jurisdiction., Russia (from the  Rus'), also officially known as the Russian Federation, is a country in Eurasia. At , Russia is the largest country in the world by surface area, covering more than one-eighth of the Earth's inhabited land area, and the ninth most populous, with over 140 million people at the end of March 2016. The European western part of the country is much more populated and urbanised than the eastern, about 77% of the population live in European Russia. Russia's capital Moscow is one of the largest cities in the world, other major urban centers include Saint Petersburg, Novosibirsk, Yekaterinburg, Nizhny Novgorod and Samara., A legislature is a deliberative assembly with the authority to make laws for a political entity such as a country or city. Legislatures form important parts of most governments; in the separation of powers model, they are often contrasted with the executive and judicial branches of government., Saint Petersburg is Russia's second-largest city after Moscow, with five million inhabitants in 2012, and an important Russian port on the Baltic Sea. It is politically incorporated as a federal subject (a federal city). Situated on the Neva River, at the head of the Gulf of Finland on the Baltic Sea, it was founded by Tsar Peter the Great on May . In 1914, the name was changed from Saint Petersburg to Petrograd, in 1924 to Leningrad, and in 1991 back to Saint Petersburg. Between 17131728 and 17321918, Saint Petersburg was the imperial capital of Russia. In 1918, the central government bodies moved to Moscow., Moscow (or ) is the capital and most populous city of Russia, with 12.2 million residents within the city limits and 16.8 million within the urban area. Moscow has the status of a Russian federal city., Yekaterinburg, alternatively romanised as "Ekaterinburg", is the fourth-largest city in Russia and the administrative centre of Sverdlovsk Oblast, located in the middle of the Eurasian continent, on the border of Europe and Asia. At the 2010 Census, it had a population of 1,349,772., Boris Nikolayevich Yeltsin (1 February 1931  23 April 2007) was a Soviet and Russian politician and the first President of the Russian Federation, serving from 1991 to 1999. Originally a supporter of Mikhail Gorbachev, Yeltsin emerged under the perestroika reforms as one of Gorbachev's most powerful political opponents. During the late 1980s, Yeltsin had been a member of the Politburo, and in late 1987 tendered a letter of resignation in protest. No one had resigned from the Politburo before. This act branded Yeltsin as a rebel and led to his rise in popularity as an anti-establishment figure., Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries., Eurasia is the combined continental landmass of Europe and Asia. The term is a portmanteau of its constituent continents. Located primarily in the Northern and Eastern Hemispheres, it is bordered by the Atlantic Ocean to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two different continents is a historical and cultural construct, with no clear physical separation between them; thus, in some parts of the world, Eurasia is recognized as the largest of five or six continents. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on the paleomagnet data., Novosibirsk is the third-most populous city in Russia after Moscow and St. Petersburg. It is the most populous city in Asian Russia, with a population of 1,473,754 as of the 2010 Census. It is the administrative center of Novosibirsk Oblast as well as of the Siberian Federal District. The city is located in the southwestern part of Siberia on the banks of the Ob River adjacent to the Ob River Valley, near the large water reservoir formed by the dam of the Novosibirsk Hydro Power Plant, and occupies an area of ., Nikolay Ilyich Travkin ( Russian :    ) ( born 19 March 1947 ) is a Russian and former Soviet politician , former member of the Supreme Soviet of the Soviet Union , member of State Duma and member of the Government of the Russian Federation ( 1994 - 1996 ) .

From 1932 to 1990, it was known as Gorky, after the writer Maxim Gorky, who was born there. The city is an important economic, transportation, scientific, educational and cultural center in Russia and the vast Volga-Vyatka economic region, and is the main center of river tourism in Russia. In the historical part of the city there are a large number of universities, theaters, museums and churches. Nizhny Novgorod is located about 400 km east of Moscow, where the Oka empties into the Volga. Population: , A constitution is a set of fundamental principles or established precedents according to which a state or other organization is governed. These rules together make up, i.e. "constitute", what the entity is. When these principles are written down into a single document or set of legal documents, those documents may be said to embody a "written" constitution; if they are written down in a single comprehensive document, it is said to embody a "codified" constitution. Some constitutions (such as the constitution of the United Kingdom) are uncodified, but written in numerous fundamental Acts of a legislature, court cases or treaties., The Supreme Soviet of the Soviet Union ("Verkhóvnyj Sovét SSSR") was the highest legislative body in the Soviet Union and the only one with the power to pass constitutional amendments. It elected the Presidium serving as the collective head of state of the Soviet Union, formed the Council of Ministers and the Supreme Court, and appointed the Procurator General of the Soviet Union., The State Duma ((Gosudarstvennaya Duma), common abbreviation:  (Gosduma)) in the Russian Federation is the lower house of the Federal Assembly of Russia (legislature), the upper house being the Federation Council of Russia. The Duma headquarters are located in central Moscow, a few steps from Manege Square. Its members are referred to as deputies. The State Duma replaced the Supreme Soviet as a result of the new constitution introduced by Boris Yeltsin in the aftermath of the Russian constitutional crisis of 1993, and approved by the Russian public in a referendum., Subject: nikolay travkin, Relation: given_name, Options: (A) africa (B) an (C) april (D) are (E) asia (F) boris (G) e .

Input: Consider Input: Context: Jerusalem , is a city located on a plateau in the Judaean Mountains between the Mediterranean and the Dead Sea. One of the oldest cities in the world, Jerusalem was named as ""Urusalima"" on ancient Mesopotamian cuneiform tablets, probably meaning "City of Shalem" after a Canaanite deity, during the early Canaanite period (approximately 2400 BCE). During the Israelite period, significant construction activity in Jerusalem began in the 9th century BCE (Iron Age II), and in the 8th century the city developed into the religious and administrative center of the Kingdom of Judah. It is considered a holy city in the three major Abrahamic religions of Judaism, Christianity and Islam., Munich (also in British English ) is the capital and largest city of the German state of Bavaria, on the banks of River Isar north of the Bavarian Alps. Munich is the third largest city in Germany, after Berlin and Hamburg, and the 12th biggest city of the European Union, with a population of above 1.5 million. The Munich Metropolitan Region is home to 5.8 million people., Gad Tsobari ( Hebrew :    sometimes Tsabari , Zobari , or Zabari ) ( born January 30 , 1944 ) is an Israeli - born light - flyweight freestyle wrestler and a member of Israel 's 1972 Olympic team . He finished 12th ( of 50 ) in his event , and was considered a possible medal threat at the Montreal Games of 1976 . Tsobari was the only survivor of the six athletes housed in Apartment 3 at 31 Connollystraße , which was the second apartment taken by Arab terrorists in the early morning hours of September 5 , 1972 in an event called the Munich massacre . Although he was originally taken hostage by the Black September terrorists , Tsobari was able to escape with the help of his already - wounded coach , Moshe Weinberg , who attacked the terrorists and received fatal gunshot wounds in the process . While Weinberg was fighting the terrorists , Tsobari dashed down a flight of stairs and through an underground garage , even as one of the terrorists pursued and shot after him . Tsobari found his way to the Olympic Village security building , where he informed officials about the break - in at the Israeli quarters . Nearly 18 hours later , Tsobari and the rest of the Israeli Olympians not taken hostage watched the helicopters take off for Fürstenfeldbruck airbase , where the remaining Israeli athletes taken hostage would be killed during a shootout with the German police . He is uncle of windsurfer and Olympic bronze medalist Shahar Tzuberi ., The Munich massacre was an attack during the 1972 Summer Olympics in Munich, West Germany, at which eleven Israeli Olympic team members were taken hostage and eventually killed, along with a German police officer, by the Palestinian terrorist group Black September. Shortly after the crisis began, they demanded 234 prisoners jailed in Israel and the German-held founders of the Red Army Faction (Andreas Baader and Ulrike Meinhof) be released. Black September called the operation "Iqrit and Biram", after two Palestinian Christian villages whose inhabitants were expelled by the IDF in 1948., Lebanon , officially known as the Lebanese Republic, is a sovereign state in Western Asia. It is bordered by Syria to the north and east and Israel to the south, while Cyprus is west across the Mediterranean Sea. Lebanon's location at the crossroads of the Mediterranean Basin and the Arabian hinterland facilitated its rich history and shaped a cultural identity of religious and ethnic diversity. At just 10,452 km (4,036 sq. mi.), it is the smallest recognized country on the entire mainland Asian continent., West Germany is the common English name for the Federal Republic of Germany or FRG (or "RFA") in the period between its creation on 23 May 1949 to German reunification on 3 October 1990. During this Cold War era, NATO-aligned West Germany and Warsaw Pact-aligned East Germany were divided by the Inner German border. After 1961 West Berlin was physically separated from East Berlin as well as from East Germany by the Berlin Wall. This situation ended when East Germany was dissolved and its five states joined the ten states of the Federal Republic of Germany along with the reunified city-state of Berlin. With the reunification of West and East Germany, the Federal Republic of Germany, enlarged now to sixteen states, became known simply as "Germany". This period is also referred to as the Bonn Republic ("Bonner Republik") by historians, alluding to the interwar Weimar Republic and the post-reunification Berlin Republic., The Gaza Strip (' ), or simply Gaza"', is a small self-governing Palestinian territory on the eastern coast of the Mediterranean Sea, that borders Egypt on the southwest for and Israel on the east and north along a border. Gaza, together with the West Bank, comprise the Palestinian territories claimed by the Palestinians as the State of Palestine. The territories of Gaza and the West Bank are separated from each other by Israeli territory. Both fall under the jurisdiction of the Palestinian Authority, but Gaza has since June 2007 been governed by Hamas, a Palestinian Islamic organization which came to power in free elections in 2006. It has been placed under an Israeli and U.S.-led international economic and political boycott from that time onwards., Iqrit (or , "Iqrith"), was a Palestinian Christian village, located northeast of Acre. Originally allotted to form part of an Arab state under the 1947 UN Partition Plan, it was seized and forcefully depopulated by the Israel Defense Forces (IDF) during the 1948 Arab-Israeli War, and their territory later became part of the new State of Israel. All of its Christian inhabitants were forced to flee to Lebanon or the Israeli village of Rameh, after they were expelled by Jewish forces in 1948, and, despite the promise that they would be returned in two weeks' time, the villagers were never allowed to return. In 1951, in response to a plea from the Iqrit villagers, the Israeli Supreme Court ruled that the former residents of Iqrit be allowed to return to their homes. However, before that happened, the IDF, despite awareness of the Supreme Court decision, destroyed the previously Christian village on Christmas Day, 1951. Descendants to this day maintain an outpost in the village church, and bury their dead in its cemetery. All attempts to cultivate its lands are uprooted by the Israeli Lands Administration., The Red Army Faction or Red Army Fraction (RAF; German: "Rote Armee Fraktion"), in its early stages commonly known as the Baader-Meinhof Group or Baader-Meinhof Gang, was a West German far-left terrorist group supported by the Stasi. The RAF was founded in 1970 by Andreas Baader, Gudrun Ensslin, Horst Mahler, and Ulrike Meinhof. The West German government considered the Red Army Faction to be a terrorist organization., Black September ("ayll al-aswad") refers to the conflict that was fought between the Palestine Liberation Organisation (PLO), under the leadership of Yasser Arafat, and the Jordanian Armed Forces, under the leadership of King Hussein primarily between 16 and 27 September 1970, with certain actions continuing until July 1971., The West Bank ("" "HaGadah HaMa'aravit") is a landlocked territory near the Mediterranean coast of Western Asia, forming the bulk of the Palestinian territories. The West Bank shares boundaries (demarcated by the Jordanian-Israeli armistice of 1949) to the west, north, and south with Israel, and to the east, across the Jordan River, with Jordan. The West Bank also contains a significant section of the western Dead Sea shore., Berndt Andreas Baader (6 May 1943  18 October 1977) was one of the first leaders of the German left-wing militant organization Red Army Faction, also commonly known as "the Baader-Meinhof Group"., Ulrike Marie Meinhof (7 October 1934  9 May 1976) was a German left-wing militant. She co-founded the Red Army Faction ("Rote Armee Fraktion") in 1970 after having previously worked as a journalist for the monthly left-wing magazine "konkret". She was arrested in 1972, and eventually charged with numerous murders and the formation of a criminal association. Before the trial concluded, Meinhof was found hanged in her prison cell in 1976., The 1972 Summer Olympics (German: "Olympische Sommerspiele 1972"), officially known as the Games of the XX Olympiad, was an international multi-sport event held in Munich, West Germany, from August 26 to September 11, 1972., Israel , officially known as the State of Israel, is a country in the Middle East, on the southeastern shore of the Mediterranean Sea and the northern shore of the Red Sea. It has land borders with Lebanon to the north, Syria to the northeast, Jordan on the east, the Palestinian territories of the West Bank and Gaza Strip to the east and west, respectively, and Egypt to the southwest. The country contains geographically diverse features within its relatively small area. Israel's financial and technology center is Tel Aviv, while its seat of government and proclaimed capital is Jerusalem, although the state's sovereignty over the city of Jerusalem is internationally unrecognized., The Red Sea (also the Erythraean Sea) is a seawater inlet of the Indian Ocean, lying between Africa and Asia. The connection to the ocean is in the south through the Bab el Mandeb strait and the Gulf of Aden. To the north lie the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez (leading to the Suez Canal). The Red Sea is a Global 200 ecoregion. The sea is underlain by the Red Sea Rift which is part of the Great Rift Valley., Subject: gad tsobari, Relation: date_of_birth, Options: (A) 1 (B) 10 (C) 18 october 1977 (D) 1934 (E) 1943 (F) 1947 (G) 1948 (H) 1949 (I) 1970 (J) 1971 (K) 1972 (L) 1977 (M) 200 (N) 2006 (O) 2007 (P) 23 (Q) 2400 bce (R) 27 (S) 3 october 1990 (T) 4 (U) 5 (V) 6 (W) 6 may 1943 (X) 7 (Y) 7 october 1934 (Z) may 1943 ([) may 1976 (\) october 1934 (]) october 1977 (^) september 1970
