Context: The Romanian Communist Party (Romanian: "", PCR) was a communist party in Romania. Successor to the pro-Bolshevik wing of the Socialist Party of Romania, it gave ideological endorsement to communist revolution and the disestablishment of Greater Romania. The PCR was a minor and illegal grouping for much of the interwar period, and submitted to direct Comintern control. During the 1930s, most of its activists were imprisoned or took refuge in the Soviet Union, which led to the creation of separate and competing factions until the 1950s. The Communist Party emerged as a powerful actor on the Romanian political scene in August 1944, when it became involved in the royal coup that toppled the pro-Nazi government of Ion Antonescu. With support from Soviet occupation forces, the PCR was able to force King Michael I into exile, and establish undisguised Communist rule in 1948. From then until 1989, it was for all intents and purposes the only legally permitted party in the country., Vasile Milea ( 1 January 1927 , Lereti , Arge -- 22 December 1989 ) was Nicolae Ceauescu 's minister of defense during the Romanian Revolution of 1989 and was involved in the reprisal phase of the revolution that caused the deaths of 162 people . On 22 December 1989 , Ceauescu sacked him for not ordering his men to fire on the demonstrators who 'd taken to the streets of Bucharest a day earlier . According to the official account , Ceauescu considered this an act of treason , and Milea committed suicide shortly afterward . However , several members of his family claim that he was killed on the orders of Ceauescu . Milea was already in severe disfavour for sending troops to quell the uprising in Timioara without ammunition . Whatever the case , Milea 's death caused the rank - and - file soldiers to go over almost en masse to the revolution , effectively ending Communist rule in Romania . A report from 2005 after a full investigation including a postmortem concludes that Milea killed himself using the weapon of one of his attendants . It seems that he only tried to get incapacitated in order to be relieved from office . But the bullet hit an artery and he died soon afterwards ., The Romanian Revolution was a period of violent civil unrest in Romania in December 1989 and part of the Revolutions of 1989 that occurred in several countries. The Romanian Revolution started in the city of Timioara and soon spread throughout the country, ultimately culminating in the show trial and execution of longtime Communist leader Nicolae Ceauescu, and the end of 42 years of Communist rule in Romania. It was also the last removal of a Communist government in a Warsaw Pact country during the events of 1989, and the only one that violently overthrew a country's government and executed its leader., Romania is a sovereign state located in Southeastern Europe. It borders the Black Sea, Bulgaria, Ukraine, Hungary, Serbia, and Moldova. It has an area of and a temperate-continental climate. With 19.94 million inhabitants, the country is the seventh-most-populous member state of the European Union. The capital and largest city, Bucharest, with its 1,883,425 inhabitants is the sixth-largest city in the EU., Nicolae Ceauescu (26 January 1918  25 December 1989) was a Romanian Communist politician. He was general secretary of the Romanian Communist Party from 1965 to 1989, and as such was the country's second and last Communist leader. He was also the country's head of state from 1967 to 1989., The Warsaw Pact, formally the Treaty of Friendship, Co-operation, and Mutual Assistance and sometimes, informally, WarPac. was a collective defense treaty among the Soviet Union and seven other Soviet satellite states in Central and Eastern Europe in existence during the Cold War. The Warsaw Pact was the military complement to the Council for Mutual Economic Assistance (CoMEcon), the regional economic organization for the communist states of Central and Eastern Europe. The Warsaw Pact was created in reaction to the integration of West Germany into NATO in 1955 per the London and Paris Conferences of 1954, but it is also considered to have been motivated by Soviet desires to maintain control over military forces in Central and Eastern Europe., Subject: vasile milea, Relation: member_of_political_party, Options: (A) romanian communist party (B) socialist party (C) union

Ex Output:
romanian communist party

Context: The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union., 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., Calcium is a chemical element with symbol Ca and atomic number 20. Calcium is a soft gray Group 2 alkaline earth metal, fifth-most-abundant element by mass in the Earth's crust. The ion Ca is also the fifth-most-abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate. Free calcium metal is too reactive to occur in nature. Calcium is produced in supernova nucleosynthesis., Northern Ireland (; Ulster Scots: "") is a top-level constituent unit of the United Kingdom in the northeast of Ireland. It is variously described as a country, province, region, or "part" of the United Kingdom, amongst other terms. Northern Ireland shares a border to the south and west with the Republic of Ireland. In 2011, its population was 1,810,863, constituting about 30% of the island's total population and about 3% of the UK's population. Established by the Northern Ireland Act 1998 as part of the Good Friday Agreement, the Northern Ireland Assembly holds responsibility for a range of devolved policy matters, while other areas are reserved for the British government. Northern Ireland co-operates with the Republic of Ireland in some areas, and the Agreement granted the Republic the ability to "put forward views and proposals" with "determined efforts to resolve disagreements between the two governments"., A chemical element or element is a species of atoms having the same number of protons in their atomic nuclei (i.e. the same atomic number, "Z"). There are 118 elements that have been identified, of which the first 94 occur naturally on Earth with the remaining 24 being synthetic elements. There are 80 elements that have at least one stable isotope and 38 that have exclusively radioactive isotopes, which decay over time into other elements. Iron is the most abundant element (by mass) making up Earth, while oxygen is the most common element in the Earth's crust., Sodium is a chemical element with symbol Na (from Latin "natrium") and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged atomthe Na cation. Its only stable isotope is Na. The free metal does not occur in nature, but must be prepared from compounds. Sodium is the sixth most abundant element in the Earth's crust, and exists in numerous minerals such as feldspars, sodalite and rock salt (NaCl). Many salts of sodium are highly water-soluble: sodium ions have been leached by the action of water from the Earth's minerals over eons, and thus sodium and chlorine are the most common dissolved elements by weight in the oceans., The alkaline earth metals are six chemical elements in column (group) 2 of the Periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). They have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure., The Kingdom of Great Britain, officially Great Britain , was a sovereign state in western Europe from 1 May 1707 to 31 December 1800. The state came into being following the Treaty of Union in 1706, ratified by the Acts of Union 1707, which united the kingdoms of England and Scotland to form a single kingdom encompassing the whole island of Great Britain and its outlying islands. It did not include Ireland, which remained a separate realm. The unitary state was governed by a single parliament and government that was based in Westminster. The former kingdoms had been in personal union since James VI, King of Scots, became King of England and King of Ireland in 1603 following the death of Queen Elizabeth I, bringing about a "Union of the Crowns". Also after the accession of George I to the throne of Great Britain in 1714, the kingdom was in a personal union with the Electorate of Hanover., The chloride ion is the anion (negatively charged ion) Cl. It is formed when the element chlorine (a halogen) gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents. Chloride salts such as sodium chloride are often very soluble in water. It is an essential electrolyte located in all body fluids responsible for maintaining acid/base balance, transmitting nerve impulses and regulating fluid in and out of cells. Less frequently, the word "chloride" may also form part of the "common" name of chemical compounds in which one or more chlorine atoms are covalently bonded. For example, methyl chloride, with the standard name chloromethane (see IUPAC books) is an organic compound with a covalent CCl bond in which the chlorine is not an anion., Magnesium is a chemical element with symbol Mg and atomic number 12. It is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column (Group 2, or alkaline earth metals) of the periodic table: all Group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure., Ireland, also described as the Republic of Ireland ('), is a sovereign state in north-western Europe occupying about five-sixths of the island of Ireland. The capital and largest city is Dublin, which is located on the eastern part of the island, and whose metropolitan area is home to around a third of the country's 4.75 million inhabitants. The state shares its only land border with Northern Ireland, a part of the United Kingdom. It is otherwise surrounded by the Atlantic Ocean, with the Celtic Sea to the south, Saint George's Channel to the south-east, and the Irish Sea to the east. It is a unitary, parliamentary republic. The legislature, the ', consists of a lower house, ', an upper house, ', and an elected President (') who serves as the largely ceremonial head of state, but with some important powers and duties. The head of government is the ' (Prime Minister, literally 'Chief', a title not used in English), who is elected by the Dáil and appointed by the President, and appoints other government ministers., Hijiki (  ,  or  hijiki ) ( Sargassum fusiforme , syn . Hizikia fusiformis ) is a brown sea vegetable growing wild on rocky coastlines around Japan , Korea , and China . Hijiki has been a part of the Japanese diet for centuries . Hijiki is rich in dietary fibre and essential minerals such as calcium , iron , and magnesium . According to Japanese folklore , hijiki aids health and beauty , and thick , black , lustrous hair is connected to regular consumption of small amounts of hijiki . Hijiki has been sold in United Kingdom natural products stores for 30 years and hijiki 's culinary uses have been adopted in North America .

Context: Buffalo Tom is an American alternative rock band from Boston , Massachusetts , formed in 1986 . Its principal members are guitarist Bill Janovitz , bassist Chris Colbourn , and drummer Tom Maginnis . The band 's name is derived from the band Buffalo Springfield and the first name of the drummer ., A "metropolitan area", sometimes referred to as a "metro area" or just "metro", is a region consisting of a densely populated urban core and its less-populated surrounding territories, sharing industry, infrastructure, and housing.
A metro area usually comprises multiple jurisdictions and municipalities: neighborhoods, townships, boroughs, cities, towns, exurbs, suburbs, counties, districts, states, and even nations like the eurodistricts. As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions. Metropolitan areas include one or more urban areas, as well as satellite cities, towns and intervening rural areas that are socio-economically tied to the urban core, typically measured by commuting patterns., Buffalo Springfield was an American-Canadian rock band, formed in Los Angeles in 1966. Their original lineup included Stephen Stills (guitar, keyboards, vocals), Dewey Martin (drums, vocals), Bruce Palmer (electric bass), Richie Furay (guitar, vocals), and Neil Young (guitar, harmonica, piano, vocals). Pioneering the folk rock genre, Buffalo Springfield, along with the Byrds, combined elements of folk and country music with British invasion influences into their early works. Their second studio album, "Buffalo Springfield Again", marked their progression to psychedelia and hard rock., The British Invasion was a phenomenon that occurred in the mid-1960s when rock and pop music acts from the United Kingdom, as well as other aspects of British culture, became popular in the United States, and significant to the rising "counterculture" on both sides of the Atlantic. Pop and rock groups such as the Beatles, the Dave Clark Five, the Kinks, the Rolling Stones, Herman's Hermits, and the Animals were at the forefront of the invasion., Los Angeles (Spanish for "The Angels"), officially the City of Los Angeles and often known by its initials L.A., is the second-most populous city in the United States (after New York City), the most populous city in California and the county seat of Los Angeles County. Situated in Southern California, Los Angeles is known for its mediterranean climate, ethnic diversity, sprawling metropolis, and as a major center of the American entertainment industry. Los Angeles lies in a large coastal basin surrounded on three sides by mountains reaching up to and over ., The Industrial Revolution was the transition to new manufacturing processes in the period from about 1760 to sometime between 1820 and 1840. This transition included going from hand production methods to machines, new chemical manufacturing and iron production processes, improved efficiency of water power, the increasing use of steam power, the development of machine tools and the rise of the factory system. Textiles were the dominant industry of the Industrial Revolution in terms of employment, value of output and capital invested; the textile industry was also the first to use modern production methods. The Industrial Revolution began in Great Britain and most of the important technological innovations were British. The social, economic and political changes in the previous centuries in Great Britain contributed. Whereas absolutism stayed the normal form of power execution through most parts of Europe, institutions ensured property rights and political safety to the people in the UK after the Glorious Revolution of 1688. Aided by these legal and cultural foundations, an entrepreneurial spirit and consumer revolution drove industrialisation in Britain, which would be emulated in countries around the world. A change in marrying patterns to getting married later made people able to accumulate more human capital during their youth, thereby encouraging economic development., Alternative rock (also called alternative music, alt-rock or simply alternative) is a genre of rock music that emerged from the independent music underground of the 1980s and became widely popular in the 1990s and 2000s. In this instance, the word "alternative" refers to the genre's distinction from mainstream rock music. The term's original meaning was broader, referring to a generation of musicians unified by their collective debt to either the musical style or simply the independent, D.I.Y. ethos of punk rock, which in the late 1970s laid the groundwork for alternative music. At times, "alternative" has been used as a catch-all description for music from underground rock artists that receives mainstream recognition, or for any music, whether rock or not, that is seen to be descended from punk rock (including some examples of punk itself, as well as new wave, and post-punk)., The harmonica, also known as a French harp or mouth organ, is a free reed wind instrument used worldwide in many musical genres, notably in blues, American folk music, classical music, jazz, country, and rock and roll. There are many types of harmonica, including diatonic, chromatic, tremolo, octave, orchestral, and bass versions. A harmonica is played by using the mouth (lips and tongue) to direct air into or out of one or more holes along a mouthpiece. Behind each hole is a chamber containing at least one reed. A harmonica reed is a flat elongated spring typically made of brass, stainless steel, or bronze, which is secured at one end over a slot that serves as an airway. When the free end is made to vibrate by the player's air, it alternately blocks and unblocks the airway to produce sound., Exile on Main St. is a double album by English rock band the Rolling Stones. It was released on 12 May 1972 by Rolling Stones Records and was the band's tenth studio album released in the United Kingdom. The record's music incorporates rock and roll, blues, soul, country, and gospel genres. Although it originally received mixed reviews, "Exile on Main St." has since been considered to be the Rolling Stones' best work while being ranked on various lists as one of the greatest albums of all time., The Byrds were an American rock band, formed in Los Angeles, California in 1964. The band underwent multiple lineup changes throughout its existence, with frontman Roger McGuinn (known as Jim McGuinn until mid-1967) remaining the sole consistent member, until the group disbanded in 1973. Although they only managed to attain the huge commercial success of contemporaries like the Beatles, the Beach Boys, and the Rolling Stones for a short period in late 1965, the Byrds are today considered by critics to be one of the most influential bands of the 1960s. Initially, they pioneered the musical genre of folk rock, melding the influence of the Beatles and other British Invasion bands with contemporary and traditional folk music. As the 1960s progressed, the band was also influential in originating psychedelic rock, raga rock, and country rock., 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., Folk rock is a musical genre combining elements of folk music and rock music. In its earliest and narrowest sense, the term referred to a genre that arose in the United States and the United Kingdom around the mid-1960s. The genre was pioneered by the Los Angeles band the Byrds, who began playing traditional folk music and songs by Bob Dylan with rock instrumentation. The term "folk rock" was coined by the U.S. music press to describe the Byrds' music in June 1965, the month in which the band's debut album was issued., Country music is a genre of United States popular music that originated in the southern United States in the 1920s. It takes its roots from the southeastern genre of United States, such as folk music (especially Appalachian folk music), and blues music. Blues modes have been used extensively throughout its recorded history. Country music often consists of ballads and dance tunes with generally simple forms and harmonies accompanied by mostly string instruments such as banjos, electric and acoustic guitars, dobros and fiddles as well as harmonicas. According to Lindsey Starnes, the term "country music" gained popularity in the 1940s in preference to the earlier term "hillbilly music"; it came to encompass Western music, which evolved parallel to hillbilly music from similar roots, in the mid-20th century. The term "country music" is used today to describe many styles and subgenres. The origins of country music are the folk music of working-class Americans, who blended popular songs, Irish and Celtic fiddle tunes, traditional English ballads, and cowboy songs, and various musical traditions from European immigrant communities. In 2009 country music was the most listened to rush hour radio genre during the evening commute, and second most popular in the morning commute in the United States., Massachusetts ; officially the Commonwealth of Massachusetts, is the most populous state in the New England region of the northeastern United States. It is bordered by the Atlantic Ocean to the east, the states of Connecticut and Rhode Island to the south, New Hampshire and Vermont to the north, and New York to the west. The state is named for the Massachusett tribe, which once inhabited the area. The capital of Massachusetts and the most populous city in New England is Boston. Over 80% of Massachusetts' population lives in the Greater Boston metropolitan area, a region influential upon American history, academia, and industry. Originally dependent on agriculture, fishing and trade, Massachusetts was transformed into a manufacturing center during the Industrial Revolution. During the 20th century, Massachusetts' economy shifted from manufacturing to services. Modern Massachusetts is a global leader in biotechnology, engineering, higher education, finance, and maritime trade., Paul Richard "Richie" Furay (born May 9, 1944) is an American singer, songwriter, and Rock & Roll Hall of Fame member who is best known for forming the bands Buffalo Springfield with Stephen Stills, Neil Young, Bruce Palmer, and Dewey Martin, and Poco with Jim Messina, Rusty Young, George Grantham and Randy Meisner. His best known song (originally written during his tenure in Buffalo Springfield, but eventually performed by Poco, as well) was "Kind Woman", which he wrote for his wife, Nancy., Bill Janovitz (born June 3, 1966) is an American musician and writer. He is the singer, guitarist, and songwriter of alternative rock band Buffalo Tom, and has also released three solo albums. Janovitz has written extensively for Allmusic, authored the "Exile on Main St." book for the 33 series, and contributed to Boston Magazine, the "Boston Phoenix, and Post Road magazine., Subject: buffalo tom, Relation: influenced_by, Options: (A) classical music (B) dylan (C) english (D) less (E) neil young (F) paul (G) self (H) spanish (I) textile (J) the beatles (K) the rolling stones
