In this task, you are given a set of context paragraph and some supporting facts to answer a question. Your task is to generate answer for given question based on set of context paragraphs and supporting facts.

Let me give you an example: Context_1 : Charles Edward Ives ( ; October 20, 1874May 19, 1954) was an American modernist composer. He is one of the first American composers of international renown, though his music was largely ignored during his life, and many of his works went unperformed for many years. Over time, he came to be regarded as an "American original". He combined the American popular and church-music traditions of his youth with European art music, and was among the first composers to engage in a systematic program of experimental music, with musical techniques including polytonality, polyrhythm, tone clusters, aleatory elements, and quarter tones, foreshadowing many musical innovations of the 20th century. Context_2 : Daniel Evan Freeman (born 27 April 1959) is an American musicologist who specializes in European art music of the eighteenth century, in particular the musical culture of eighteenth-century Prague and the Bohemian lands. He is also active as a pianist and music editor. Context_3 : Art music (also known as Western classical music, cultivated music, serious music, canonic music, and more flippantly, real music or normal music) is an umbrella term that refers to musical traditions, implying advanced structural and theoretical considerations and a written musical tradition. "Serious" or "cultivated" music are terms frequently used as a contrast for ordinary, everyday music (popular and folk music, also called "vernacular music"). After the 20th century, art music was divided into two extensions: "serious music" and "light music". Context_4 : In the history of European art music, the term "common practice period" refers to the era between the formation and the dissolution of the tonal system. Though there are no exact dates for this phenomenon, most features of the common-practice period persisted from the mid to late baroque period, through the Classical and Romantic periods, or roughly from around 1650 to 1900. While certain prevailing patterns and conventions characterize the music of this period, the time period also saw considerable stylistic evolution. Some conventions evolved during this period that were rarely employed at other times during what may still be labeled "common practice" (for example, Sonata Form). Thus, the dates 16501900 are necessarily nebulous and arbitrary borders that depend on context. The most important unifying feature through this time period concerns a harmonic language to which modern music theorists can apply Roman numeral analysis. Context_5 : The Festival Oude Muziek Utrecht ("Utrecht Early Music Festival") is an annual music festival that showcases and celebrates early European art music. The ten-day festival takes place in the Dutch city of Utrecht, and begins in August. The programme comprises concerts, activities, lectures, exhibitions, and a symposium. Context_6 : Assaf Shelleg (Hebrew: ), is a musicologist and pianist, a senior lecturer of musicology at The Hebrew University of Jerusalem. He was previously the Schusterman Visiting Assistant Professor of Musicology and Jewish Studies in the Department of Religious Studies at the University of Virginia (201114), and had taught prior to that as the visiting Efroymson Scholar in the Jewish, Islamic & Near Eastern Languages and Cultures Department at Washington University in St. Louis (200911). Shelleg specializes in twentieth-century Jewish and Israeli art music and has published in some of the leading journals in both musicology and Israel Studies on topics ranging from the historiography of modern Jewish art music to the theological networks of Israeli art music. Shelleg's book, "Jewish Contiguities and the Soundtrack of Israeli History", appeared in November 2014 with Oxford University Press. The book studies the emergence of modern Jewish art music in central and Western Europe (1910s-1930s) and its translocation to Palestine/Israel (1930s-1970s), exposing the legacies of European antisemitism and religious Judaism in the making of Israeli art music. Moving to consider the dislocation of modern Jewish art music the book examines the paradoxes embedded in a Zionist national culture whose rhetoric negated its pasts, only to mask process of hybridizations enchained by older legacies. "Jewish Contiguities" has won the 2015 Engle Prize for the study of Hebrew Music, and the 2016 Jordan Schnitzer Book Award. Context_7 : Vocal harmony is a style of vocal music in which a consonant note or notes are simultaneously sung as a main melody in a predominantly homophonic texture. Vocal harmonies are used in many subgenres of European art music, including Classical choral music and opera and in the popular styles from many Western cultures ranging from folk songs and musical theater pieces to rock ballads. In the simplest style of vocal harmony, the main vocal melody is supported by a single backup vocal line, either at a pitch which is above or below the main vocal line, often in thirds or sixths which fit in with the chord progression used in the song. In more complex vocal harmony arrangements, different backup singers may sing two or even three other notes at the same time as each of the main melody notes, mostly with consonant, pleasing-sounding thirds, sixths, and fifths (although dissonant notes may be used as short passing notes). Context_8 : David Wallis Reeves (February 14, 1838 March 8, 1900), also known as D. W. Reeves or Wally Reeves, was an American composer, cornetist, and bandleader. He developed the American march style, later made famous by the likes of John Philip Sousa, and his innovations include adding a countermelody to the American march form in 1876. Sousa called Reeves "The Father of Band Music in America", and stated he wished he himself had written Reeves' "Second Regiment Connecticut National Guard March". Charles Ives also borrowed from the "Second Connecticut" on four occasions. Context_9 : "Indian classical music is one of many forms of art music that have their roots in particular regional cultures. For other "classical" and art music traditions, see List of classical and art music traditions." Context_10 : Progressive music is music that subverts genre and expands stylistic boundaries outwards. Rooted in the idea of a cultural alternative, musical progressiveness embodies a continuous move between explicit and implicit references to genres and strategies derived from various cultural domains, such as European art music, Celtic folk, West Indian, or African. The word "progressive" comes from the basic concept of "progress", which refers to development and growth by accumulation, and is often deployed in numerous music genres such as progressive country, progressive folk, progressive jazz, and (most significantly) progressive rock. fact_1 : Charles Ives also borrowed from the "Second Connecticut" on four occasions. fact_2 : Charles Edward Ives ( ; October 20, 1874May 19, 1954) was an American modernist composer. fact_3 : He combined the American popular and church-music traditions of his youth with European art music, and was among the first composers to engage in a systematic program of experimental music, with musical techniques including polytonality, polyrhythm, tone clusters, aleatory elements, and quarter tones, foreshadowing many musical innovations of the 20th century. Question: What is the birthyear of the American composer that borrowed from "Second Connecticut" on four occasions and combined American popular and church-music traditions with European art music?
The answer to this example can be: 1874May
Here is why: From the fact_1 from context _8, and fact _2 and fact _3 from context _1, we can arrive at 1874 May which is accurate answer of given question.

OK. solve this:
Context_1 : The Convention of Balta Liman of 1 May 1849 was an agreement between the Russian Empire and the Ottomans regulating the political situation of the two Danubian Principalities (the basis of present-day Romania), signed during the aftermath of the Revolutions of 1848. Moldavia, which had been placed under Russian occupation in late spring 1848 following a revolutionary attempt, and Wallachia, where a liberal Provisional Government had briefly assumed power before facing a common Ottoman-Russian reaction, were confirmed their previous status of Ottoman suzerainty and Russian protectorate (first established in 183132 by the "Regulamentul Organic"). Minor provisions were added, signifying a relative increase in Ottoman influencenamely, "hospodars" were no longer elected by the local National Assemblies for life, and instead appointed by the Sublime Porte for seven-year terms. A common military presence was maintained until 1851. The document led to the appointment of Barbu Dimitrie Stirbei as hospodar of Wallachia and Grigore Alexandru Ghica as hospodar of Moldavia. The Convention was rendered void by the Crimean War (during which the Principalities fell under Austrian occupation), and the statutory system itself was annulled by the 1856 Treaty of Paris. Context_2 : Pavel Ludikar (3 March 1882 19 February 1970) was a Czech operatic bass who had a highly successful international singing career from 1904 through 1944. He began his career in his native country and by 1911 had arisen at many of the major opera houses in Europe. From 1913 to 1935 his career was mainly centered in North and South America. The peak of his opera career was reached at the Metropolitan Opera in New York City, where he was committed from 1926 to 1932. He returned to Europe in 1935 to assume directorship of the Neues deutsches Theatre in Prague, remaining there until the theatre was closed in September 1938 due to Nazi occupation, effectively ending his stage career. The height of his later years in Prague was his portrayal of the title hero in the world premiere of Ernst Krenek's "Karl V" in June 1938. Context_3 : N. D. Cocea (common rendition of Nicolae Dumitru Cocea, ] , also known as Niculae, Niculici or Nicu Cocea; November 29, 1880 February 1, 1949) was a Romanian journalist, novelist, critic and left-wing political activist, known as a major but controversial figure in the field of political satire. The founder of many newspapers and magazines, including "Viata Sociala", "Rampa", "Facla" and "Chemarea", collaborating with writer friends such as Tudor Arghezi, Gala Galaction and Ion Vinea, he fostered and directed the development of early modernist literature in Romania. Cocea later made his name as a republican and anticlerical agitator, was arrested as an instigator during the 1907 peasant revolt, and played a leading role in regrouping the scattered socialist clubs. His allegiances however switched between parties: during World War I, he supported the Entente Powers and, as a personal witness of the October Revolution, the government of Soviet Russia, before returning home as a communist. Context_4 : Dumitru-Dorin Prunariu (] ; born 27 September 1952) is a Romanian cosmonaut. He flew in space aboard Soyuz 40 spacecraft and Salyut 6 space laboratory. He was in team with another Romanian cosmonaut called Dumitru Dediu. Context_5 : Mitica (] ) is a fictional character who appears in several sketch stories by Romanian writer Ion Luca Caragiale. The character's name is a common hypocoristic form of "Dumitru" or "Dimitrie" (Romanian for "Demetrius"). He is one of the best-known figures in Caragiale's 1901 collection "Momente si schite", as well as in Romanian humor at large. Mitica is a male resident of Bucharest whose background and status are not always clear, generally seen as an allegory of the average Bucharester or through extension, inhabitants of Romania's southern regionsWallachia and Muntenia. According to accounts, he was based on a resident of Sinaia, whom Caragiale had befriended. Context_6 : Franz Ernst Christian Neumann (30 January 1834 6 March 1918) was a German pathologist who was a native of Konigsberg. His common name was Ernst Christian Neumann (without Franz at the beginning). Context_7 : The Ministries Trial (or, officially, the United States of America vs. Ernst von Weizsacker, et al.) was the eleventh of the twelve trials for war crimes the U.S. authorities held in their occupation zone in Germany in Nuremberg after the end of World War II. These twelve trials were all held before U.S. military courts, not before the International Military Tribunal, but took place in the same rooms at the Palace of Justice. The twelve U.S. trials are collectively known as the "Subsequent Nuremberg Trials" or, more formally, as the "Trials of War Criminals before the Nuremberg Military Tribunals" (NMT). Context_8 : Prof. Dr. Ernst Willi Messerschmid (born May 21, 1945) is a German physicist and former astronaut. Context_9 : Mesne (pronounced "mean") profits are sums of money paid for the occupation of land to a person with right of immediate occupation, where no permission has been given for that occupation. The concept is feudal in origin, and common in countries which rely on the English legal system (including many former British colonies). The word is derived from the root word demesne. Context_10 : On May 14, 1981 Romania became the 11th country in the world to have an astronaut in space. That astronaut, Dumitru Prunariu is today's president of Romanian Space Agency. fact_1 : Dumitru-Dorin Prunariu (] ; born 27 September 1952) is a Romanian cosmonaut. fact_2 : Prof. Dr. Ernst Willi Messerschmid (born May 21, 1945) is a German physicist and former astronaut. Question: Dumitru Prunariu and Ernst Messerschmid, have which occupation in common?
Answer:
astronaut
