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.
One 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 1650–1900 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: אסף שלג‎ ‎ ), 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 (2011–14), 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 (2009–11). 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
Solution is here: 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?
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 generated question.

Now, solve this: Context_1 : State Route 27 (SR 27) is a 90 mi state highway serving Whitman and Spokane counties, located in the eastern region of the U.S. state of Washington. The highway travels generally north from U.S. Route 195 (US 195) through Pullman, Palouse, Tekoa, and Spokane Valley to SR 290 north of an interchange with Interstate 90 (I-90). SR 27 serves the Palouse region as part of the Palouse Scenic Byway and travels between US 195 to the west and US 95 to the east in Idaho, with several auxiliary routes connecting to the two other highways. The highway has been part of the state highway system since 1913, as a part of the Second Division of the Eastern Route of the Inland Empire Highway between Pullman and Oakesdale that later became a branch of Primary State Highway 3 (PSH 3), as well as Secondary State Highway 3H (SSH 3H) in 1937. Both highways were combined to form SR 27 during the 1964 highway renumbering and the designation was extended south to the US 195 bypass of Pullman in 1975 and north to SR 290 in 1991. Context_2 : The Frequency Changing Station in Spokane, Washington is a building listed on the National Register of Historic Places. It was built by the Spokane and Inland Empire Railroad in 1908 to house electrical equipment used by the electric railway. Power was generated at the Nine Mile Falls dam and transmitted to the Frequency Changing Station. The station provided direct current to the streetcar network within the city of Spokane. To provide power to the rail network outside Spokane, the station converted a portion of the power to alternating current and fed it to a series of electrical substations spaced about 15 mi on the operating line. The substations then converted power back to direct current for the streetcars, but also sold power at 110 volts AC to the communities. Context_3 : The Cowles Company is a diversified media company in Spokane, Washington in the US. The company owns and operates the newspaper "The Spokesman-Review" in Spokane, founded in 1894. The company operates Inland Empire Paper Company, television stations, and interests in real estate, insurance, marketing and financial services. Context_4 : The Old National Bank building, located in Spokane, Washington, was completed in 1911 and was the first skyscraper located in the Inland Northwest. This fifteen story tower reaches to a height of 217 feet (66 m) above the Spokane valley and remained the tallest building in the city until the Paulsen Center was completed across the street on Riverside Ave. The Old National Bank building served as a symbol of prosperity for the rising economy of the Inland Empire. Context_5 : The Spokane and Inland Empire Railroad Company (S.&I.E.R.R.Co.) was an electrified interurban railway operating in Spokane, Washington and vicinity, extending into northern and central Idaho. The system originated in several predecessor roads beginning c. 1890, incorporated in 1904, and ran under its own name to 1929. It merged into the Great Northern Railway and later, the Burlington Northern Railroad, which operated some roads into the 1980s. Context_6 : The Burlington Northern Railroad (reporting mark BN) was a United States-based railroad company formed from a merger of four major U.S. railroads. Burlington Northern operated between 1970 and 1996. Context_7 : The Inland Empire Blues Society (IEBS) is a nonprofit organization dedicated to supporting, preserving and promoting the blues through social events, such as concerts, festivals, and a newsletter. IEBS is a member of the Blues Foundation. Although based in Spokane Washington, IEBS represents a broader area generally known as the Inland Empire of the Pacific Northwest. Context_8 : Playfair Race Course, (known as the Spokane Interstate Fair from 1901–1935) was the home of horse racing in Spokane, Washington, from 1901 to 2000. The track started out as a four furlong oval, later expanded to five furlongs in 1946. The premier races run at the track were the Playfair Mile, Spokane Derby, and Inland Empire Marathon. Context_9 : San Bernardino is a city located in the Riverside-San Bernardino metropolitan area (sometimes called the "Inland Empire"). It serves as the county seat of San Bernardino County, California, United States. As one of the Inland Empire's anchor cities, San Bernardino spans 81 sqmi on the floor of the San Bernardino Valley and has a population of 209,924 as of the 2010 census. San Bernardino is the 17th-largest city in California and the 100th-largest city in the United States. San Bernardino is home to numerous diplomatic missions for the Inland Empire, being one of four cities in California with numerous consulates (the other three being Los Angeles, San Diego and San Francisco). The governments of Guatemala and Mexico have also established their consulates in the downtown area of the city. Context_10 : Nine Mile Falls Dam is a dam on the Spokane River, in the unincorporated community of Nine Mile Falls, Washington. It was built on the site of the falls in 1908, creating Nine Mile Reservoir. The dam was designed by the New York engineering firm of Sanderson & Porter, and originally constructed to satisfy the power needs of the Spokane and Inland Empire Railroad interurban trolley lines. fact_1 :  It merged into the Great Northern Railway and later, the Burlington Northern Railroad, which operated some roads into the 1980s. fact_2 :  Burlington Northern operated between 1970 and 1996. Answer: Burlington Northern Railroad
