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.
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
Example solution: 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?
Example 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.

Problem: Context_1 : Tough Trucks, also known as Tuff Trucks, Pro Arena Trucks and, Street Warriors, are off-road truck competitions held at 4x4 truck jamborees and monster truck events. Tough Truck competitions are a downsized form of short course off-road racing. They are run as a side act at most monster truck shows. Depending on venue and promoter, the tracks can range from as big as a football field, to as small as a hockey rink. Most track set ups consist of a handful of double jumps, single banzai jumps, uneven/rocker hills, and dirt kicker ramps, again depending on venue and promoter. Some tracks are run in Chicago Style/Round E Round Track or S-Style Track. Some competitions are run as a single pass time trial, or side by side racing. Context_2 : Trucks and Tractor Power was a long running weekly television show on TNN featuring mud bogging, tractor pulling and monster trucks. The show's original hosts were Stan Rhoads and former Bigfoot driver Rich Hooser, along with pit reporter Mike Goss. Gary Lee replaced Stan Rhoads. Army Armstrong later joined as a pit reporter, and later, when Hooser left the show, became color commentator. The show initially began in 1989 as a vehicle for TNT Motorsports events, complimenting their ESPN show Powertrax and syndicated show Tuff Trax, and would typically alternate between truck and tractor pulls and monster trucks, with National Mud Racing Organization mud races intermittently. After TNT was bought out by the United States Hot Rod Association in 1991, the show began primarily airing the Pendaliner Monster Truck Series and NMRO mud races held at Special Events' 4-Wheel and Off-Road Jamborees. A frequent feature of these shows was a highlight segment of "Tough Truck" amateur off-road races near the end of the monster truck episodes. The final season of Trucks and Tractor Power had Gary Lee as the host at the Monster Truck Thunder Drags, with Dave Rief, and later Tom Rivers, for the Jamborees. At the end of the 1996 season, the Pendaliner cancelled their sponsorship of the monster truck series, causing the show to be subsequently cancelled. Context_3 : Dennis Anderson (born October 24, 1960) is an American professional monster truck driver. He is the creator, team owner, and former driver of "Grave Digger" on the USHRA Monster Jam circuit. Anderson is from Kill Devil Hills, North Carolina, where he currently resides. Context_4 : A monster truck is a pickup truck modified with a larger suspension and larger tires, usually for recreational uses. Today pickup trucks are still used, however SUV bodies as well as themed trucks are driven and most of the bodies are now made of fiberglass rather than metal. Themed trucks vary from car bodies, SUV bodies, and even animal themed bodies. A competition monster truck should meet guidelines by being 12 feet tall, 12 feet wide, and as of 2015, should be equipped with specifically made 462lb BKT 66-inch off-road tires. Monster trucks used to be side acts at popular motocross events and mud bogs but today they are usually the main attraction with motocross and mud bogging being the complementary shows. Context_5 : Monster Nationals is the name of the monster truck series run by Image Promotions. The series primarily consists of monster truck racing and freestyle in indoor arenas. The events typically have only two parallel sets of cars on an empty concrete floor as a race track. The event format is similar to those of the USHRA Thunder Nationals series, due to owner George Eisenhart being the former director of that series. Trucks currently running in the series include Big Dawg, Lil' Miss Dangerous, Nitemare, Raminator, and Rammunition. In previous years, Bigfoot also competed. Unlike its USHRA counterpart, the Monster Nationals series runs indoor arena shows during the winter season and outdoor fairground shows during the summer. Some monster trucks that are new to the Monster Nationals include Tailgator (Doug Noelke's newest creation), Holman's Beast and teammate truck Ironman, and more. Returning trucks to the circuit include War Wagon, formerly owned by Jeff Cook who sold it to Andy Hoffman, and Samson, who ran the outdoor series in 2003 and 2007. The Monster Nationals, along with intense monster truck racing, also features some extreme stunts and performances such as a jet-powered Jeep, a jet-powered recliner, FMX Freestyle, BMX Freestyle, and car-eating transformers. Context_6 : Grave Digger is a monster truck racing team in the Feld Entertainment Monster Jam series. There are nine Grave Diggers being driven by different drivers to allow them to make appearances at more events, but their flagship driver is creator Dennis Anderson. Dennis Anderson is the head of the Grave Digger department team. He is in charge of the training of the younger drivers and the fleet of trucks. Grave Digger is considered to be one of the most influential and iconic monster trucks of all time. Context_7 : Thunder Truck Rally (released as Monster Trucks in Europe) is a monster truck racing video game developed by Reflections and published by Psygnosis where players select a monster truck or otherwise 4X4 vehicle equipped with monster truck tires and have the option of either racing or crushing cars in an arena. Context_8 : Adam Anderson (born December 5, 1985, in Norfolk, VA) is an American professional monster truck driver. He currently drives the monster truck "Grave Digger" on the USHRA Monster Jam circuit. Adam is the son of Dennis Anderson, a monster truck driver and 4-time Monster Truck World Champion. Adam currently resides in his home town of Powells Point, NC. Context_9 : Black Stallion is a monster truck that races on the USHRA circuit and for other promoters. Black Stallion started out as a stock 1982 Ford F350 back in 1982, owned and modified by Michael Vaters. The first modification was a homemade 12" lift kit, since such kits were unavailable at the time. Mike then later added two sunroofs, an Alpine stereo system, a Ford 460 Engine, Rockwell 5 ton toploaders, Clark 20 ton planetaries, 66" terra tires, a 9" television and later on, a 1988 Ford F series front end. Between 1990 and 1991, Mike realized the future of monster trucks, which was racing. To be competitive, Mike replaced the leaf springs with airbags, the old heavy split ring rims with lightweight one piece rims, fiberglass body pieces, cutting the tires, gutting the interior out, 4 linking the truck and putting in a bigger engine. The modifications proved to be beneficial to Mike, with close races with First Blood, and competing in some Pendaliner Special Events racing events. After a violent rollover in Bloomsburg Pennsylvania in 1991, Mike decided to put King shocks on the truck, which he later added coil springs in 1992. Along with the coil springs, Mike also removed the airbags. Mike is credited as the first owner to use bypass shocks. Also for 1992, Mike changed the front clip to a 1992 Ford F-series front end. Mike rarely ran this truck after he built the popular Boogey Van in 1993, driven by his then wife, Pam Vaters. Due to this, the truck was nicknamed Rodney, after the comedian, Rodney Dangerfield. Mike then built a truck for the 1996 season for research and development, named Black Stallion 2000, since his crew members joked about Mike not building a new truck for himself until the new millennium. This chassis is still running strong to this day. For his 20th anniversary, Mike decided to repaint Black stallion, with the front of the truck yellow, going into black with a horse face painted on. The truck currently has the same paint scheme. The drivers for 2016 are Michael Vaters & Matt Cody. Vaters will compete in the Fox Sports 1 Championship Series. Cody will travel to Birmingham, Toronto, Newark, Charleston, Columbia, Worcester, Wheeling & Baton Rouge. Context_10 : Blue Thunder is a monster truck that raced in the USHRA Monster Jam series. It was sponsored by the truck division of Ford Motor Company and Live Nation. The truck has several similarities with the monster truck Bigfoot. Some fans saw Blue Thunder as a replacement for Bigfoot in the Monster Jam series. The truck had been moderately successful and won several major events during its existence. However, it has not yet won a championship. Blue Thunder is used by Ford Motor Company for promotional purposes along with competition. The truck is currently driven by Matt Cody. The truck did not compete in 2012 when Todd LeDuc moved to Metal Mulisha after driving Blue Thunder in 2011. The truck was brought back in 2013 with a veteran driver, Dan Evans; who use to own and drive Destroyer, then Team Hot Wheels, as well as a new paint job. fact_1 : Dennis Anderson (born October 24, 1960) is an American professional monster truck driver. fact_2 : He is the creator, team owner, and former driver of "Grave Digger" on the USHRA Monster Jam circuit. fact_3 : Grave Digger is a monster truck racing team in the Feld Entertainment Monster Jam series. fact_4 : Grave Digger is considered to be one of the most influential and iconic monster trucks of all time. Answer: Grave Digger
Solution: Dennis Anderson is a professional driver known for driving which monster truck considered to be one of the most influential and iconic monster trucks of all time?
