PROBLEM: Context_1 : Mortal Sin were an Australian thrash metal band that formed in 1985 and existed over four distinct periods until 2012. The band released five albums and were the first local thrash metal band to tour internationally. According to Australian musicologist, Ian McFarlane, they were one of "two leading lights... [of] a small, but fervent underground thrash/speed metal scene." Context_2 : Kronik is a compilation album released by the Canadian thrash metal/progressive metal band Voivod in 1998 on Hypnotic Records. It is their eleventh release altogether, featuring remixes, previously unreleased songs, and live recordings. The album features the track "Ion", which is played during the opening credits of the "Heavy Metal 2000" movie. It was re-released in 2004 by Candlelight Records. Context_3 : Annihilator is a Canadian thrash metal band founded in 1984 by vocalist, guitarist, bassist, songwriter, engineer, producer, mixer and mastering engineer Jeff Waters and former vocalist John Bates. They are the highest-selling heavy metal group from Canada in Canadian history, having sold more than three million albums worldwide, although most of their sales have been generated outside of the band's home country. Along with Sacrifice, Voivod and Razor, Annihilator is credited as one of the "Big 4" of Canadian thrash metal. Context_4 : Voivod is a Canadian thrash metal band from Jonquière, Quebec. The band consists of Denis "Snake" Bélanger (vocals), Daniel "Chewy" Mongrain (guitar), Dominique "Rocky" Laroche (bass) and Michel "Away" Langevin (drums). Their musical style has changed several times since the band's origin in the early 1980s. Starting out as a speed metal band, Voivod have added a mix of progressive metal and thrash metal to create their own unique metal style, and they are credited as one of the "big four" Canadian thrash metal bands, along with Sacrifice, Razor, and Annihilator. Context_5 : Sacrifice is a Canadian thrash metal band from Toronto, Ontario. The band was formed by guitarists Rob Urbinati and Joe Rico in 1983. Sacrifice played a prominent role in the 1980s scene in Toronto, and along with Voivod, Razor and Annihilator, they are considered one of the "Big 4" of Canadian thrash metal. The band released four studio albums before parting ways in 1993. After coming back together to play a reunion concert in 2006, they released their fifth studio album "The Ones I Condemn" on Brazilian label Marquee Records in 2009. Although the band faced numerous lineup changes, especially in their early days, founding guitarists Urbinati, Rico and bassist Scott Watts recorded every studio album and demo and drummer Gus Pynn on everything but the "Apocalypse Inside" demo and CD. Context_6 : Deliverance is the 1989 self-titled debut album by the Christian speed/thrash metal band Deliverance. The original Intense Records pressing is now considered a valuable collectable. It was reissued, minus 2 songs in 1998 on KMG Records as a two-disc set along with the 1990 album "Weapons of Our Warfare". It was officially re-released late 2008 with 2 bonus tracks on Retroactive Records. The album was ranked at No. 44 on "Metal Hammer"' s top 50 thrash metal albums of all-time list. In 2010, "HM Magazine" listed "Deliverance" No. 31 on its Top 100 Christian Rock Albums of All Time list stating that "'If You Will' into 'The Call' is almost as good as metal gets (-Doug Van Pelt)" and that "this record would forever change and impact me and the Christian metal music scene as we knew it!"(-Bill Balford). Heaven's Metal fanzine ranked it No. 3 on its Top 100 Christian metal albums of all-time list. About.com writer Dan Marsicano wrote "Metal with a religious concept is not for everybody, and Deliverance doesn’t try to pander to the secular crowd. So, if you don’t mind a little preaching, their music is straight-to-the-gut thrash metal at a time where the genre was getting more expansive with its themes and sound. For giving Christian metal a thrash hero to rally behind, Deliverance gets the nod for this week’s Retro Recommendation." Context_7 : Tales from the Grave in Space is the third studio album by Irish thrash metal band Gama Bomb, and one of the first albums ever to be released as a free download by a signed band. In a partnership between the band and record label Earache Records, the album was available for free download from 5 November 2009, hosted by RapidShare.

Since their formation, Forbidden have broken up and reformed twice with numerous line-up changes. The most recent line-up of the band comprised Anderson (vocals), Locicero (guitar), Matt Camacho (bass), Steve Smyth (guitar) and Sasha Horn (drums). Along with Death Angel, Vio-lence, Defiance, Testament and Exodus (the latter of the two had featured original Forbidden drummer Paul Bostaph), they were one of the most successful Bay Area thrash metal bands and earned a loyal fanbase in the underground music community and critical acclaim, with their debut album "Forbidden Evil" (1988) regarded by critics as a classic thrash metal album and the follow-up, "Twisted Into Form", as something of a masterpiece within the tech-thrash genre. Their earlier style was technical thrash metal, but the band later experimented with alternative and groove metal elements on their fourth album "Green" (1997).

SOLUTION: Annihilator

PROBLEM: Context_1 : A helpmate is a type of chess problem in which both sides cooperate in order to achieve the goal of checkmating Black. In a helpmate in "n" moves, Black moves first, then White, each side moving "n" times, to culminate in White's "nth" move checkmating Black. (In a helpmate in two for example, sometimes abbreviated "h#2", the solution consists of a Black move, a White move, a second Black move, then a second White move, giving checkmate.) Although the two sides cooperate, all moves must be legal according to the rules of chess. Context_2 : The Latin name Abnoba Mons (Pre-Germanic "Abnoba"; Ancient Greek "τὰ Ἄβνοβα", "ta Abnoba", Ἀβνοβαῖα ὄρη "Abnobaia orē") is the name of a mountain range that was already known to ancient authors Pliny and Tacitus. The name has been traditionally, primarily associated in historical research with the Black Forest. Ptolemy used the toponym in his A.D. 150 publication, "Geographia", as a mountain range lying within Germania magna (ὄρη ) with its southern extent at 31° 49' and its northern extremity at 31° 52'. The geographer clearly did not restrict this name to present day Black Forest, but to an entire mountain chain. Context_3 : Kari Juhani Jormakka (Helsinki, 21 January 1959 – 13 January 2013, Vienna) was a Finnish architect, historian, critic and pedagogue. He initially studied philosophy at the University of Helsinki before switching to studying architecture at Helsinki University of Technology, graduating in 1985. He completed a PhD in architecture theory, with a thesis titled "Constructing Architecture", at Tampere University of Technology in 1992. His main theoretical position is characterized by studies in the ontology of architecture, defining the constructed nature of buildings as works of interpretation. As such a work may then be significantly determined by the period when it was created, a position that Jormakka critiqued through theories of Zeitgeist primarily associated with Friedrich Hegel and, in regard to modernist works, Arthur C. Danto. In "Eyes that do not see" (2011), the last published work during his lifetime, Jormakka applied these ideas to the theory of Functionalism best associated with the thinking of architect Le Corbusier and his fellow functionalists. Context_4 : GHI Media, LLC, doing business as Devolver Digital, is an American video game publisher and film distributor based in Austin, Texas, which is primarily associated with the "Serious Sam" and "Hotline Miami" series. The company was founded in March 2008 by former Gathering of Developers and Gamecock Media Group executives, Mike Wilson, Harry A. Miller IV, and Rick Stults. Context_5 : The Grand Tour was the traditional trip of Europe undertaken by mainly upper class European young men of sufficient means and rank (or those of more humble origin who could find a sponsor), as well as young women if they were also of sufficient means, and accompanied by a chaperon, such as other family members, when they had come of age (about the age of 21 years old) . The custom flourished from about 1660, until the advent of large-scale rail transport in the 1840s, and was associated with a standard itinerary. It served as an educational rite of passage. Though primarily associated with the British nobility and wealthy landed gentry, similar trips were made by wealthy young men of Protestant Northern European nations, and from the second half of the 18th century, by some South and North Americans. The tradition declined with the lapse of neo-classical enthusiasm and after rail and steamship travel made the journeys much easier when Thomas Cook made the "Cook's Tour" of early mass tourism a byword. Context_6 : Tiki-taka (commonly spelled "tiqui-taca" ] in Spanish) is a style of play in football characterised by short passing and movement, working the ball through various channels, and maintaining possession. The style is primarily associated with La Liga club Barcelona, especially during the era of manager Pep Guardiola. Its development and influence goes back to Johan Cruyff's tenure as manager in the early 1990s all the way to the present. Tiki-Taka is also associated with the Spanish national team under managers Luis Aragonés and Vicente del Bosque. Tiki-taka moves away from the traditional thinking of formations in football to a concept derived from zonal play. Context_7 : Black Spectre has two meanings in the Marvel Universe. The first Black Spectre is the name of a fictional organization which first appeared in "Daredevil" #108 (March 1974) and was created by writer Steve Gerber and penciller Bob Brown.

The second Black Spectre is a fictional supervillain who first appeared in "Moon Knight" #25 (November 1982) and was created by writer Doug Moench and penciller Bill Sienkiewicz. The character is one of the greatest enemies of the vigilante Moon Knight. Context_8 : Mars Black is an Omaha, Nebraska based hip-hop artist, born in Brooklyn, New York.

PROBLEM: Context_1 : The Eklutna River is a 22-mile (35 km) long river located in the Southcentral region of the U.S. state of Alaska. A degraded anadromous stream of glacial origin, it originates at Eklutna Glacier and flows through Eklutna Lake and a canyon up to 350 feet (107 m) deep, emptying into the Knik Arm of Cook Inlet approximately 17 miles (27 km) northeast of Anchorage. It has one significant tributary, Thunderbird Creek, which enters the south bank about 1 km (0.6 mi) upstream from where the river exits the canyon and forms an alluvial fan. Due to water impoundments on the Eklutna River for power generation, Thunderbird Creek is currently the main source of water in the river. The river is located entirely within the limits of the Municipality of Anchorage. Context_2 : The Berg River (also called Great Berg River or in Afrikaans: Bergrivier) is a river located just north of Cape Town in the Western Cape Province of South Africa. It is approximately 294 km (183 mi) long with a catchment area of 7,715 km² (2979 mi²) and outlets into the Atlantic Ocean. About 65% of the Berg River area is under agriculture. The major towns in the Berg River area are Velddrif and Laaiplek near the coast, Piketberg, Hopefield, Moorreesburg and Darling further inland, and Wellington and Paarl in the upper catchment. The lead source of the Berg River is south of Franschhoek in the Drakenstein Mountains. Context_3 : The Kazan River (Inuktitut "Harvaqtuuq", Inuktitut syllabics ᓴᕐᕙᖅᑑᖅ; meaning "strong rapids", "the big drift" or "place of much fast flowing water"), is a Canadian Heritage River located in Nunavut, Canada. The Dene name for the river was Kasba-tue meaning “white partridge river.” The name was apparently changed to Kazan in the late 19th century due to the influence of Order of Mary Immaculate missionaries. The river headwaters are in northern Saskatchewan at Kasba Lake, and it flows north for about 1000 km (621 mi) before emptying into Baker Lake ( ), on the opposite side of the mouth of the Thelon River. Along its course the river flows through several lakes, including Ennadai Lake and Yathkyed Lake, over the Kazan Falls (25 m ), down a red sandstone gorge and through both boreal forest and tundra. It is the last section of the river, below Ennadai Lake, that is above the timber line and is designated a Canadian Heritage River. Context_4 : The Derwent River is a river located in Tasmania, Australia. The river rises in the state's Central Highlands and descends more than 700 m over 200 km , flowing through Hobart, the state's capital city, before emptying into Storm Bay and flowing into the Tasman Sea. The banks of the Derwent were once covered by forests and occupied by Tasmanian Aborigines. European settlers farmed the area and during the 20th century many dams were built on its tributaries for the generation of hydro-electricity. The River Derwent Starts at Lake St Clair. Context_5 : The Poteau River is a 141-mile (227 km) long river located in the U.S. states of Arkansas and Oklahoma. It is the only river in Oklahoma that flows north and is the seventh largest river in the state. It is a tributary of the Arkansas River, which itself is a tributary of the Mississippi River. Context_6 : The Bald River is a river located in Monroe County, Tennessee in the Cherokee National Forest. It is a tributary of the Tellico River. Just before it empties into the Tellico, the river falls over a large waterfall, Bald River Falls, which is variously reported as being between 80 and 100 feet (25 and 30 m) high. The river then flows under a bridge on Forest Service Road 120 (the falls and the river mouth are both very readily visible from the bridge). The falls is regarded as the most impressive and scenic waterfall in East Tennessee. The river is short in length but powerful as it flows through a steep, densely wooded valley and it is constantly replenished by the area's frequent rains. It rises just north of the North Carolina state line near the crest of the Unicoi Mountains and flows northeast for a short distance before turning to the northwest. Context_7 : The Ducie River is a river located on the Cape York Peninsula in Far North Queensland, Australia. Context_8 : The Wicomico River is a 13.0 mi tributary of the lower tidal portion of the Potomac River located in the U.S. state of Maryland south of Washington, DC. The river empties into the Potomac at Cobb Island and St. Margaret's Island. Its watershed area (excluding water) is 77 sqmi , with 2% impervious surface in 1994. in Charles, St. Mary's, and southern Prince George's counties. The lower section of the river forms part of the boundary between Charles and St. Mary's counties. The Wicomico River was designated a Scenic River under the Maryland Scenic River Act in 1968, and there are Scenic River Commissions for it in both Charles and St. Mary's counties (see links below). Context_9 : Queensland (abbreviated as QLD, or less frequently Q) is the second-largest and third-most-populous state in the Commonwealth of Australia. Situated in the north-east of the country, it is bordered by the Northern Territory, South Australia and New South Wales to the west, south-west and south respectively. To the east, Queensland is bordered by the Coral Sea and Pacific Ocean. The state is the world's sixth largest sub-national entity, with an area of 1,852,642 km. Context_10 : In archaeology, survey or field survey is a type of field research by which archaeologists (often landscape archaeologists) search for archaeological sites and collect information about the location, distribution and organization of past human cultures across a large area (e.g. typically in excess of one hectare, and often in excess of many km). Archaeologists conduct surveys to search for particular archaeological sites or kinds of sites, to detect patterns in the distribution of material culture over regions, to make generalizations or test hypotheses about past cultures, and to assess the risks that development projects will have adverse impacts on archaeological heritage. The surveys may be: (a) "intrusive" or "non-intrusive", depending on the needs of the survey team (and the risk of destroying archaeological evidence if intrusive methods are used) and; (b) "extensive" or "intensive", depending on the types of research questions being asked of the landscape in question. Surveys can be a practical way to decide whether or not to carry out an excavation (as a way of recording the basic details of a possible site), but may also be ends in themselves, as they produce important information about past human activities in a regional context. fact_1 : The Ducie River is a river located on the Cape York Peninsula in Far North Queensland, Australia. fact_2 : Queensland (abbreviated as QLD, or less frequently Q) is the second-largest and third-most-populous state in the Commonwealth of Australia. fact_3 :  The state is the world's sixth largest sub-national entity, with an area of 1,852,642 km.
