question:
Passage: Detroit techno is an offshoot of Chicago house music which developed in the early and mid-1980s. One of the earliest hits was "Big Fun" by Inner City. Detroit techno developed as the DJ The Electrifying Mojo did his radio program, which fused eclectic sounds into the signature Detroit techno sound. This sound, also influenced by European electronica (Kraftwerk, Art of Noise), Japanese synthpop (Yellow Magic Orchestra), early B-boy (breakdancing) Hip-Hop (Man Parrish, Soul Sonic Force) and Italo disco (Doctor's Cat, Ris, Klein M.B.O.), was further pioneered by Juan Atkins, Derrick May, and Kevin Saunderson, known as the Belleville Three.
Derrick May a.k.a. "MAYDAY" and Thomas Barnett released "Nude Photo" in 1987 on May's label "Transmat Records", which helped start the Detroit techno music scene. This record was played on Chicago's Hot Mix 5 Radio DJ mix show and in Chicago clubs. A year later, Transmat released "Strings of Life". Transmat Records also released such as 1988's "Wiggin". As well, Derrick May had releases on Kool Kat Records and many remixes for underground and mainstream recording artists. Kevin Saunderson's company KMS Records contributed many releases that were as much house music as they were techno. These tracks were well received in Chicago and played on Chicago radio and in clubs.Blake Baxter's 1986 recording, "When we Used to Play / Work your Body", 1987's "Bounce Your Body to the Box" and "Force Field", "The Sound / How to Play our Music" and "the Groove that Won't Stop" and a remix of "Grooving Without a Doubt". In 1988, as house music became more popular among general audiences, Kevin Saunderson's group Inner City with Paris Gray released the 1988 hits "Big Fun" and "Good Life", which eventually were picked up by Virgin Records. Each EP / 12 inch single sported remixes by Mike "Hitman" Wilson and Steve "Silk" Hurley of Chicago and Derrick "Mayday" May and Juan Atkins of Detroit. In 1989, KMS had another hit release of "Rock to the Beat" which was a theme in Chicago dance clubs.The Detroit Techno scene was also met with some conflict. Reynold's "A Tale of Three Cities" discussed the acceptance and inclusion of marginalized groups within each genre of Techno, House, and Garage. Detroit turned out to be where wealthier black youth tried to discourage ghetto youth from enjoying Techno. Comparing that to the religious sanctuary that House provided, Chicago became a true "house" to the black, Hispanic, and gay communities in Chicago. 
Question: What type of music was "Big Fun"?
answer:
Detroit techno.


question:
Passage: Marojejy National Park is a national park in the Sava Region of northeastern Madagascar. It covers 55,500 ha (214 sq mi) and is centered on the Marojejy Massif, a mountain chain that rises to an elevation of 2,132 m (6,995 ft).  Access to the area around the massif was restricted to research scientists when the site was set aside as a strict nature reserve in 1952.  In 1998, it was opened to the public when it was converted into a national park.  It became part of the World Heritage Site known as the Rainforests of the Atsinanana in 2007.  Despite its rugged terrain, poaching and selective logging are still persistent problems, particularly since the start of the 2009 political crisis in Madagascar.  Mining, slash-and-burn agriculture, and wood collection also pose threats to the park and its wildlife.
The wide range of elevations and rugged topography of the massif create diverse habitats that transition quickly with changes in altitude.  Warm, dense rainforest can be found at lower elevations, followed by shorter forests at higher elevations, followed still by cloud forest, and topped near the peaks with the only remaining undisturbed mountain scrub in Madagascar.  Better growing conditions for plants can be found on the eastern side of the mountains, which receives more rain than the western side.  This habitat diversity lends itself to high levels of biodiversity.  At least 118 species of bird, 148 species of reptile and amphibian, and 11 species of lemur are known to occur within Marojejy National Park.  One of the lemurs, the silky sifaka (Propithecus candidus) is listed among "The World's 25 Most Endangered Primates".  The helmet vanga (Euryceros prevostii) is considered the iconic bird species of the park.
One path leads from the entrance of the park to the summit.  There are three camps along the route: Camp Mantella at 450 m (1,480 ft) in elevation in lowland rainforest, Camp Marojejia at 775 m (2,543 ft) at the transition between lowland and montane rain forest, and Camp Simpona at 1,250 m (4,100 ft) in the middle of the montane rainforest.  Camp Simpona acts as a base camp for the trek to the summit, a route that stretches 2 km (1.2 mi) and can take up to four or five hours to traverse. 
Question: How many km is the route that stretches to the summit in the park that is centered on the Marojejy Massif?
answer:
2.

Passage: YouTube cover artist Mike Massé recorded a live acoustic version of "Paranoid Android" with Jeff Hall on 9/8/08 at the Pie Pizzeria in Salt Lake City, Utah.American metal band System of a Down additionally performed a cover of Paranoid Android at a Los Angeles live performance in 2000.Jazz pianist Brad Mehldau recorded a nine-minute cover of "Paranoid Android" on his album Largo (2002), featuring percussionists Jim Keltner and Matt Chamberlain, as well as a horn section.

Lullaby Renditions of Radiohead and Plastic Mutations: The Electronic Tribute to Radiohead.
The reggae group Easy Star All-Stars covered OK Computer in its entirety for Radiodread (2006). Producer Michael G noted that "Paranoid Android" was particularly difficult to arrange for reggae, saying "There are songs like 'Paranoid Android', which flips between 4/4 time and 7/8 time about 13 times, and I also had to think about other ways to reinterpret those parts with horns, melodica, organ ... it was a great challenge."Sia Furler covered the song for the neo soul tribute Exit Music: Songs with Radio Heads (2006), and this version later appeared on The O.C. episode "The Chrismukk-huh?".
"Paranoid Android" has also been covered by classical musicians. Christopher O'Riley arranged "Paranoid Android" for a single piano and performed the song on Hold Me to This (2005).
Los Angeles string quartet The Section recorded the song for Strung Out on OK Computer: The String Quartet Tribute to Radiohead (2001); half of this quartet went on to form the Section Quartet, who performed "Paranoid Android" and the rest of OK Computer during two concerts in October 2006.Weezer covered "Paranoid Android" in both a live studio version released as a YouTube video and in concerts during their 2011 summer tour. Pitchfork's Tom Breihan called the Weezer cover "a fucking weird experience", and Jenny Eliscu of Rolling Stone criticised the song as "mainly boring" for not venturing far enough from Weezer's traditional sound.A piano cover was featured in an episode of the HBO television series Westworld in 2016.
