Context: The McDonnell Aircraft Corporation was an American aerospace manufacturer based in St. Louis, Missouri. The company was founded on July 6, 1939 by James Smith McDonnell, and was best known for its military fighters, including the F-4 Phantom II, and manned spacecraft including the Mercury capsule and Gemini capsule. McDonnell Aircraft later merged with the Douglas Aircraft Company to form McDonnell Douglas in 1967., Aerospace is the human effort in science, engineering and business to fly in the atmosphere of Earth (aeronautics) and surrounding space (astronautics). Aerospace organisations research, design, manufacture, operate, or maintain aircraft and/or spacecraft. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications., A rotorcraft or rotary-wing aircraft is a heavier-than-air flying machine that uses lift generated by wings, called rotary wings or rotor blades, that revolve around a mast. Several rotor blades mounted on a single mast are referred to as a rotor. The International Civil Aviation Organization (ICAO) defines a rotorcraft as "supported in flight by the reactions of the air on one or more rotors". Rotorcraft generally include those aircraft where one or more rotors are required to provide lift throughout the entire flight, such as helicopters, cyclocopters, autogyros, and gyrodynes. Compound rotorcraft may also include additional thrust engines or propellers and static lifting surfaces., A rocket (from Italian "rocchetto" "bobbin") is a missile, spacecraft, aircraft or other vehicle that obtains thrust from a rocket engine. Rocket engine exhaust is formed entirely from propellant carried within the rocket before use. Rocket engines work by action and reaction and push rockets forward simply by expelling their exhaust in the opposite direction at high speed, and can therefore work in the vacuum of space., The Douglas Aircraft Company was an American aerospace manufacturer based in Southern California. It was founded in 1921 by Donald Wills Douglas, Sr. and later merged with McDonnell Aircraft in 1967 to form McDonnell Douglas. Douglas Aircraft Company largely operated as a division of McDonnell Douglas (MD) after the merger. MD later merged with Boeing in 1997., The Boeing Company is an American multinational corporation that designs, manufactures, and sells airplanes, rotorcraft, rockets, and satellites worldwide. The company also provides leasing and product support services. Boeing is among the largest global aircraft manufacturers; it is the second-largest defense contractor in the world based on 2015 revenue, and is the largest exporter in the United States by dollar value. Boeing stock is a component of the Dow Jones Industrial Average., Embraer S.A. is a Brazilian aerospace conglomerate that produces commercial, military, executive and agricultural aircraft and provides aeronautical services. It is headquartered in São José dos Campos, São Paulo State., McDonnell Douglas was a major American aerospace manufacturing corporation and defense contractor formed by the merger of McDonnell Aircraft and the Douglas Aircraft Company in 1967. Between then and its own merger with Boeing in 1997, it produced a number of well-known commercial and military aircraft such as the DC-10 airliner and F-15 Eagle air-superiority fighter., As of September 2015 , American Airlines operates a mainline fleet of 939 aircraft , making it the largest commercial fleet in the world . It primarily operates a mix of Airbus and Boeing ( including McDonnell Douglas ) narrow - body and wide - body aircraft , as well as one narrow - body variant from Embraer . American is currently in the process of the largest fleet renewal in its history , with over 300 aircraft on order from Airbus and Boeing . American Airlines also announced a new livery to be painted on all aircraft . American Airlines expects to be done repainting all aircraft by the end of 2017 ., An airplane or aeroplane (informally plane) is a powered, fixed-wing aircraft that is propelled forward by thrust from a jet engine or propeller. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research. Commercial aviation is a massive industry involving the flying of tens of thousands of passengers daily on airliners. Most airplanes are flown by a pilot on board the aircraft, but some are designed to be remotely or computer-controlled., Subject: american airlines fleet, Relation: item_operated, Options: (A) 4 (B) aircraft (C) airliner (D) spacecraft
airliner

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

Context: Catholic religious orders are, historically, a category of Catholic religious institutes., Religiosam vitam is the "incipit" designating a Papal bull issued on December 22, 1216 by Pope Honorius III. It gave universal recognition to the Dominican Order. The Order already had monasteries in Rome, Paris and Boulogne and had already been locally recognized by the bishop of Toulouse the year before - its creation had coincided with the Albigensian Crusade in southern France, in whose support the Dominicans had been very active. It adopted the rule of St Augustine, but was also regulated by rulings and decisions taken by regular general chapters., A friar is a member of one of the mendicant orders founded since the twelfth or thirteenth century; the term distinguishes the mendicants' itinerant apostolic character, exercised broadly under the jurisdiction of a superior general, from the older monastic orders' allegiance to a single monastery formalized by their vow of stability. The most significant orders of friars are the Dominicans, Franciscans, Augustinians and Carmelites., France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans and had a total population of almost 67 million people as of January 2017. It is a unitary semi-presidential republic with the capital in Paris, the country's largest city and main cultural and commercial centre. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse and Bordeaux., The Order of Preachers (postnominal abbreviation O.P.), also known as the Dominican Order, is a mendicant Catholic religious order founded by the Spanish priest Dominic of Caleruega in France, approved by Pope Honorius III via the papal bull "Religiosam vitam" on 22 December 1216. Members of the order, who are referred to as "Dominicans", generally carry the letters O.P. after their names, standing for "Ordinis Praedicatorum", meaning "of the Order of Preachers". Membership in the order includes friars, nuns, active sisters, and affiliated lay or secular Dominicans (formerly known as tertiaries, though recently there has been a growing number of associates who are unrelated to the tertiaries)., Leonardo di Piero Dati ( 1360 -- 16 March 1425 ) was an Italian friar and humanist . He was Master general of the Dominican Order from 1414 to his death . He was a Prior of Santa Maria Novella from 1401 , and took part in the Council of Pisa of 1409 . Dati was the head of the Dominicans belonging to the Roman obedience during the Great Schism . At the time of the Council of Constance , Dati became Master General of a reunited Dominican Order . Dati then focused on the internal reform of the order , authoring the tract Lamentationes de regularibus observantiis lapsis , in which he expressed strong dissatisfaction with the laxity and confusion of the order . His sermons at Pisa and Constance include references to literary texts , and he was well known as an author of commentaries on Aristotle . Leonardo also gave financial aid to his brother Gregorio , a Florentine merchant and diarist . Both Leonardo and Gregorio Dati are attributed authorship of La Sfera ( `` The Sphere '' ) , an astronomical - geographic poemetto in ottave , written in the second half of the 14th century , and a work much popular in its time . This work in verse gives information about the world , the marinaresche compass and other things , adding observations , notes about travel and designs . In some manuscripts of La Sfera there are designs representing ports , headlands , islands , linked by many lines . Dati 's sermons on the feast of St. Francis ( October 1416 ) and the feast of the Circumcision of Jesus ( January 1417 ) advocated respect for papal power and reform within the context of the established order . The earlier sermon touched off an exchange of polemical memoranda between Dati and supporters of conciliar supremacy . Dati then addressed issues raised in this exchange in the later sermon . Dati 's discussion of circumcision was traditional for his time , describing the Jewish rite as superseded by baptism . He is buried in the Cappella Rucellai at Santa Maria Novella . His tombstone is attributed to Lorenzo Ghiberti ., Subject: leonardo dati, Relation: occupation, Options: (A) bishop (B) commercial (C) friar (D) member (E) priest (F) religious
