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

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. Answer: 1874May
The answer to this example can be: 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?
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 generated question.

OK. solve this:
Context_1 : The Bureau des Longitudes (] ) is a French scientific institution, founded by decree of 25 June 1795 and charged with the improvement of nautical navigation, standardisation of time-keeping, geodesy and astronomical observation. During the 19th century, it was responsible for synchronizing clocks across the world. It was headed during this time by Francois Arago and Henri Poincare. The Bureau now functions as an academy and still meets monthly to discuss topics related to astronomy. Context_2 : Massachusetts was the first colony in New England with slave ownership and was a center for the slave trade throughout the 17th and 18th centuries. No legislation was passed that abolished slavery until the Thirteenth Amendment in 1865 was ratified by the state. Instead, the practice of slavery was ended through case law; and as an institution it died out in the late 18th century through judicial actions litigated on behalf of slaves seeking manumission. These court cases, starting in 1781, heard arguments contending that slavery was a violation of Christian principles and also a violation of the constitution of the commonwealth. 1783 saw additional high-profile court cases that began a general trend of slaves winning their emancipation on a case-by-case basis through lawsuit. As slavery dwindled in the last decade of the 18th century in Massachusetts, many of the instances where it remained, the slaveholders sometimes applied semantics of a name change to indentured servitude to maintain their property. The 1790 federal census, however, listed no slaves. Massachusetts was a center for the abolition movement in the 19th century. Context_3 : The Andover Public Library is located on Church Street in Andover, Maine, United States. Although a private library funded by subscription was founded in the town in 1795, it was not until the establishment of the Andover Public Library Association in 1891 that movement to a publicly-funded library began. It was originally quartered in a room of the Andover Town Hall, until 1943, when its present building was purchased from a Universalist church organization. The building is one of only two octagonal religious buildings known to have been built anywhere in Maine, and was probably the last building in the state built with inspiration from Orson Squire Fowler's promotion of octagonal buildings in the 19th century. On January 27, 1981, it was added to the National Register of Historic Places. Context_4 : Spidertown was a small, agricultural supply and services based community in southwestern Ontario, Canada that existed in the last half of the 19th and the early 20th century. The site of the former hamlet is located at the present intersection of Mount Carmel Drive, Blackbush Line and Salem Road, on the boundary between the current municipality of North Middlesex and the municipality of South Huron. Little is currently known of Spidertown's founding, nor the origin of its name. The hamlet is described in one source as consisting, at one point in time, of "taverns on both corners" and "four homes". It is known, that in the latter 19th century a general store was operated in the community by Alexander Todd, presumably the same individual who operated two other general stores during the period at Maguire and Moray as well. A medical doctor, T. L. Flaherty, maintained a practice in a corner house in the hamlet in the latter 19th century, but is known to have moved his office to Mount Carmel, 2 km to the east, before 1898. It is believed that Spidertown began to go into decline because of its inability to compete economically with the nearby hamlet of Mount Carmel. Spidertown is recorded as having disappeared by 1914. Context_5 : The Luxembourg Commission was a labor commission in the 19th century. It was introduced by the Provisional Government of France which formed on 25 February 1848, following the abdication of Louis-Philippe. The establishment of the Luxembourg Commission, an assembly of workers' delegates headed by Louis Blanc, was charged with the task of surveying social problems and suggesting solutions; an elegant gesture from the Provisional government. It was discontinued later the same year. Context_6 : The historical records for the Shroud of Turin can be separated into two time periods: before 1390 and from 1390 to the present. The period until 1390 is subject to debate and controversy among historians. Prior to the 14th century there are some allegedly congruent but controversial references such as the Pray Codex. It is often mentioned that the first certain historical record dates from 1353 or 1357. However the presence of the Turin Shroud in Lirey, France, is only undoubtedly attested in 1390 when Bishop Pierre d'Arcis wrote a memorandum where he charged that the Shroud was a forgery. The history from the 15th century to the present is well documented. In 1453 Margaret de Charny deeded the Shroud to the House of Savoy. As of the 17th century the shroud has been displayed (e.g. in the chapel built for that purpose by Guarino Guarini) and in the 19th century it was first photographed during a public exhibition. Context_7 : The Divan- Humayun, in English the Imperial Council, was the "de facto" cabinet of the Ottoman Empire for most of its history. Initially an informal gathering of the senior ministers presided over by the Sultan in person, in the mid-15th century the Council's composition and function became firmly regulated. The Grand Vizier, who became the Sultan's deputy as the head of government, assumed the role of chairing the Council, which comprised also the other viziers, charged with military and political affairs, the two "kadi'askers" or military judges, the "defterdars" in charge of finances, the "nisanc" in charge of the palace scribal service, and later the Kapudan Pasha, the head of the Ottoman Navy, and occasionally the "beylerbey" of Rumelia and the Agha of the Janissaries. The Council met in a dedicated building in the Second Courtyard of the Topkapi Palace, initially daily, then for four days a week by the 16th century. Its remit encompassed all matters of governance of the Empire, although the exact proceedings are no longer known. It was assisted by an extensive secretarial bureaucracy under the "reis ul-kuttab" for the drafting of appropriate documents and the keeping of records. The Imperial Council remained the main executive organ of the Ottoman state until the mid-17th century, after which it lost most of its power to the office of the Grand Vizier. With the Tanzimat reforms of the early 19th century, it was eventually succeeded by a Western-style cabinet government. Context_8 : The Oxford Main Street Historic District is a national historic district encompassing the historic center of Oxford, Massachusetts. The 95 acre district extends along Main Street from Huguenot Street in the south to Front Street in the north. Its oldest buildings are residential houses built in the late 19th century, while most of the properties were built in the 19th century, with Greek Revival architecture predominating. The oldest commercial building, the John Wetherell Store, was built c. 1817, and now houses offices. The district includes four churches, including the 1793 Universalist church and 1829 First Congregational Church, and a number of municipal buildings, including the town hall, two schools, and the 1903 Classical Revival Charles Larned Memorial Library. Context_9 : Jules Henri Poincare (] ; 29 April 1854 17 July 1912) was a French mathematician, theoretical physicist, engineer, and philosopher of science. He is often described as a polymath, and in mathematics as "The Last Universalist" by Eric Temple Bell, since he excelled in all fields of the discipline as it existed during his lifetime. Context_10 : The history of Tufts University, originally Tufts College, can be traced back to 1847 when the Universalist Church set up convention for the creation of a university for the parish. In 1852, the college was established when Boston businessman Charles Tufts donated 20 acres of land to the church to establish the college. It is the second oldest college that was founded in the Boston area. . During the 19th century the college grew. The official college seal, bearing the motto Pax et Lux (Peace and Light) was adopted in 1857. The school colors of brown and blue were selected in 1876. Tufts' mascot became Jumbo when P.T. Barnum gave a natural history museum to the university. fact_1 : The Bureau des Longitudes (] ) is a French scientific institution, founded by decree of 25 June 1795 and charged with the improvement of nautical navigation, standardisation of time-keeping, geodesy and astronomical observation. fact_2 : During the 19th century, it was responsible for synchronizing clocks across the world. fact_3 : He is often described as a polymath, and in mathematics as "The Last Universalist" by Eric Temple Bell, since he excelled in all fields of the discipline as it existed during his lifetime. Answer: the improvement of nautical navigation
Answer:
What was the institution headed by The Last Universalist during the 19th century charged with?
