See one example below:
Problem: 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?
Solution: 1874May
Explanation: 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.

Problem: Context_1 : Located on the western coast of the large island of Luzon, facing the South China Sea, is a UNESCO World Heritage Site in that it is one of the few towns left in the Philippines whose old structures have mostly remained intact, and it is well known for its cobblestone streets and a unique architecture of the Philippine colonial era which fuses Native Philippine and Oriental building designs and construction, with colonial Spanish architecture. Former Philippine president Elpidio Quirino, the sixth President of the Philippines, was born in Vigan, at the former location of the Provincial Jail (his father was a warden); he resided in the Syquia Mansion. Context_2 : There are 61 Grade II* listed war memorials in England, out of over 2,000 listed war memorials. In the United Kingdom, a listed building is a building or structure of special historical or architectural importance; listing offers the building legal protection against demolition or modification, which requires permission from the local planning authority. Listed buildings are divided into three categoriesgrade I, grade II*, and grade IIwhich reflect the relative significance of the structure and may be a factor in planning decisions. Grade I is the most significant and accounts for 2.5% of listed buildings, while grade II accounts for 92%. Grade II* is the intermediate grade accounting for the remaining 5.5%; it is reserved for "particularly important buildings of more than special interest". A war memorial listed at grade II* may be of particular artistic interest or accomplishment, of a highly unusual design, or of significant historical interest below that required for grade I. It is explicitly unnecessary for the architect or sculptor to be well known in order for a memorial to be listed at grade II*. As part of the commemorations of the centenary of the First World War, Historic Englandthe government body responsible for listing in Englandis running a project with the aim of significantly increasing the number of war memorials on the National Heritage List for England. Context_3 : The Haskell Free Library and Opera House (French: Bibliotheque et salle d'opera Haskell) is a neoclassical building that straddles the international border in Rock Island (now part of Stanstead), Quebec and Derby Line, Vermont. The Opera House opened on June 7, 1904, and was deliberately built on the border between Canada and the United States. It was declared a heritage building by both countries in the 1970s. Context_4 : A line house is a building deliberately located so that an international boundary passes through it. The term is perhaps more frequently used in reference to the boundary between New England and eastern Canada than to other places. The most well known such building on the boundary between the United States and Canada is the Haskell Free Library and Opera House in Stanstead, Quebec and Derby Line, Vermont. The border is marked on the floor in a reading room and an auditorium. A number of single-family residences and some industrial buildings straddle the boundary in those two towns. Context_5 : Churubusco-Franklin Centre is a border crossing connecting Franklin Centre, Quebec to Churubusco, New York on the CanadaUS border. In an unusual lack of coordination between the two countries, the United States committed to building a new $6.8 Million border inspection station at Churubusco, at the same time Canada committed to closing its Franklin Centre border station. The result is an apparent permanent condition where travelers may enter the US from Canada via southbound Quebec Route 209 at this location, but they must return via another route instead of taking northbound New York State Route 189. Context_6 : The CanadaUnited States border (French: "Frontiere entre le Canada et les Etats-Unis"), officially known as the International Boundary, is the longest international border in the world between two countries. It is shared between Canada and the United States, the second- and fourth-largest countries by area, respectively. The terrestrial boundary (including portions of maritime boundaries in the Great Lakes, and on the Atlantic, Pacific, and Arctic coasts) is 8,891 km long, of which 2,475 km is Canada's border with Alaska. Eight Canadian provinces and territories (Yukon, British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Quebec, and New Brunswick), and thirteen U.S. states (Alaska, Washington, Idaho, Montana, North Dakota, Minnesota, Michigan, Ohio, Pennsylvania, New York, Vermont, New Hampshire, and Maine) are located along the border. Context_7 : Franklin Street Presbyterian Church and Parsonage is a historic Presbyterian church located at 100 West Franklin Street at Cathedral Street, northwest corner in Baltimore, Maryland, United States. The church is a rectangular Tudor Gothic building dedicated in 1847, with an addition in 1865. The front features two 60 foot flanking octagonal towers are also crenelated and have louvered belfry openings and stained glass Gothic-arched windows. The parsonage has walls of brick, heavy Tudor-Gothic window hoods, and battlements atop the roof and was built in 1857. This church was incorporated in 1844 by a group of men from the First Presbyterian Church then located at the northwest corner of East Fayette Street and North Street (now Guilford Avenue) in downtown (later relocated in 1854 to West Madison Street and Park Avenue in Mount Vernon-Belvedere neighborhood after selling their previous third church building of 1790-95 to the Federal Government which built a U.S. Courthouse there [to 1889, replaced again 1932] dedicated in 1860 by President James Buchanan). They felt the need for a new church in that fast-growing northern section of the city formerly "Howard's Woods" of Col. John Eager Howard's (Revolutionary War commander of the famed "Maryland Line" regiment of the Continental Army) country estate "Belvedere" (mansion located at intersection of North Calvert and East Chase Streets, razed 1875) where the Washington Monument was erected with its four surrounding park squares just two blocks from their new building. Franklin Street Church was also located on "Cathedral Hill" in the southern part of the community bordering downtown and across the street from the old Baltimore Cathedral (Basilica of the National Shrine of the Assumption of the Blessed Virgin Mary) erected 1806-1821 and designed by Benjamin Latrobe. Later in 1882-1886, philanthropist Enoch Pratt founded his central library for the new Enoch Pratt Free Library then facing West Mulberry Street at Cathedral, a block south which was replaced in 1931-33 by a new central library building encompassing the entire block and now directly across Franklin Street from the F.S.P.C. In 1973, the two historic congregations reunited to form The First and Franklin Street Presbyterian Church and was centered at the First Church site on West Madison and Park. The Franklin Street building was used by the merged congregation for a time and then sold to a fundamentalist independent Protestant congregation and later re-sold to the present "New Unity Church Ministries". Across Cathedral Street to the northeast was the 1820s era Greek Revival home designed by Robert Mills (who also did the Washington Monument two blocks away) which later was occupied by the original Maryland Club, an exclusive Southern-leaning dining and leisure society of gentlemen, founded 1857 that was once threatened by Massachusetts Militia Gen. Benjamin F. Butler, U.S.A. when he occupied Baltimore at the beginning of the Civil War on May 13, 1861, and fortified Federal Hill with a Fort and cannons overlooking the harbor and city, "to put a shot into it" if he spied a reputed rebel flag flying or any discontent to declared martial law. The Club later moved to North Charles and East Eager Streets in 1892 and mansion was later replaced by the former Central Building of the Young Men's Christian Association of Central Maryland (YMCA) which was closed in the 1980s and the building renovated as the Mount Vernon Hotel and Cafe. Context_8 : Relations between Canada and the United States of America historically have been extensive, given a shared border and ever-increasing close cultural, economical ties and similarities. The shared historical and cultural heritage has resulted in one of the most stable and mutually beneficial international relationships in the world. For both countries, the level of trade with the other is at the top of the annual combined import-export total. Tourism and migration between the two nations have increased rapport, but border security was heightened after the terrorist attacks in the United States on September 11, 2001. The U.S. is ten times larger in population and has the dominant cultural and economic influence in the world. Starting with the American Revolution, when anti-American Loyalists fled to Canada, a vocal element in Canada has warned against US dominance or annexation. The War of 1812 saw invasions across the border. In 1815, the war ended with the border unchanged and demilitarized, as were the Great Lakes. The British ceased aiding First Nation attacks on American territory, and the United States never again attempted to invade Canada. Apart from minor raids, it has remained peaceful. Context_9 : The Hyder - Stewart Border Crossing connects the communities of Hyder, Alaska and Stewart, British Columbia on the CanadaUS border. It can be reached by British Columbia Highway 37A from Stewart and International Street from Hyder. There is no US border inspection station at this crossing, making it the only land border crossing where a person may legally enter the United States without reporting for inspection. The US closed its border station, which was located in the same building as the Boundary Gift Shop, in the 1950s. As a result, all flights leaving the Hyder Seaplane Base to other cities in Alaska are treated as international arrivals, and all passengers, including Hyder residents must be inspected by U.S. Customs and Border Protection officers. Hyder is the easternmost community in Alaska. Context_10 : Blackfoot Crossing Historical Park is a complex of historic sites on the Siksika 146 Indian reserve in Alberta, Canada. This crossing of the Bow River was traditionally a bison-hunting and gathering place for the Siksika people and their allies in the Blackfoot Confederacy. Nearby are the remains of an ancient earthlodge village, believed to have been built by people from the Upper Mississippi valley in what is now the United States. It is unique in being an example of a permanent village on the plains: an area associated with nomadic hunting. The crossing became an important place in Canadian history when Treaty 7 was signed here between the native nations of what is now southern Alberta and the Canadian government on behalf of the Crown in 1877. It was also here that Crowfoot, chief of the Siksika, is believed to have died and been buried. As well, Poundmaker, a chief of the Cree who had been ceremonially adopted by Crowfoot in order to create peace between the Blackfoot and the Cree, was also buried here until being moved in 1967. In 1925 the traditional gathering site and the treaty signing site were declared National Historic Sites of Canada by the federal government's Historic Sites and Monuments Board of Canada. In 1972, the earthlodge village was also declared a national historic site. fact_1 : The most well known such building on the boundary between the United States and Canada is the Haskell Free Library and Opera House in Stanstead, Quebec and Derby Line, Vermont. fact_2 : It was declared a heritage building by both countries in the 1970s. Question: What era was the well known buliding on the border of United States and Canada declared a heritage building by both?
Solution:
It was declared a heritage building by both countries in the 1970s.
