Context: The Northern Territory (abbreviated as NT) is a federal Australian territory in the central and central northern regions of Australia. It shares borders with Western Australia to the west (129th meridian east), South Australia to the south (26th parallel south), and Queensland to the east (138th meridian east). To the north, the territory is bordered by the Timor Sea, the Arafura Sea and the Gulf of Carpentaria. Despite its large areaover , making it the third largest Australian federal divisionit is sparsely populated. The Northern Territory's population of 244,000 (2016) makes it the least populous of Australia's eight major states and territories, having fewer than half as many people as Tasmania., A sea is a large body of salt water that is surrounded in whole or in part by land. More broadly, "the sea" is the interconnected system of Earth's salty, oceanic watersconsidered as one global ocean or as several principal oceanic divisions. The sea moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. Although the sea has been traveled and explored since prehistory, the modern scientific study of the seaoceanographydates broadly to the British "Challenger" expedition of the 1870s. The sea is conventionally divided into up to five large oceanic sectionsincluding the International Hydrographic Organization's four named oceans (the Atlantic, Pacific, Indian, and Arctic) and the Southern Ocean; smaller, second-order sections, such as the Mediterranean, are known as "seas"., A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague., The Meda River is a river in the Kimberley of Western Australia . The river is formed when the Lennard River splits into two channels just north of Mount Marmion , the other channel being the May River . Continuing to flow westward the river eventually discharges into Stokes Bay , King Sound which is north - east of Derby . The river was named in 1881 by a pioneer of the area , George Julius Brockman during an expedition in the Kimberley area . The river is named after HMS Meda , an Admiralty surveying vessel that charted the coastline in the area including the river mouth in 1880 . The traditional owners of the areas around the river are the Ongkarango peoples . The Meda has three tributaries ; The Lennard River , May River and Hawkstone Creek ., The Indian Ocean is the third largest of the world's oceanic divisions, covering (approximately 20% of the water on the Earth's surface). It is bounded by Asia on the north, on the west by Africa, on the east by Australia, and on the south by the Southern Ocean or, depending on definition, by Antarctica. It is named after the country of India. The Indian Ocean is known as "Ratnkara", ""the mine of gems"" in ancient Sanskrit literature, and as "Hind Mahsgar", ""the great Indian sea"", in Hindi., The Great Australian Bight is a large oceanic bight, or open bay, off the central and western portions of the southern coastline of mainland Australia., The Southern Ocean, also known as the Antarctic Ocean or the Austral Ocean, comprises the southernmost waters of the World Ocean, generally taken to be south of 60° S latitude and encircling Antarctica. As such, it is regarded as the fourth-largest of the five principal oceanic divisions: smaller than the Pacific, Atlantic, and Indian Oceans but larger than the Arctic Ocean. This ocean zone is where cold, northward flowing waters from the Antarctic mix with warmer subantarctic waters., Western Australia (abbreviated as WA) is a state occupying the entire western third of Australia. It is bounded by the Indian Ocean to the north and west, the Great Australian Bight and Southern Ocean to the south, the Northern Territory to the north-east and South Australia to the south-east. Western Australia is Australia's largest state with a total land area of 2,529,875 square kilometres (976,790 sq mi), and the second-largest country subdivision in the world  however, a significant part of it is sparsely populated. The state has about 2.6 million inhabitants, around 11% of the national total. 92% of the population lives in the south-west corner of the state., An ocean (the sea of classical antiquity) is a body of saline water that composes much of a planet's hydrosphere. On Earth, an ocean is one of the major conventional divisions of the World Ocean, which covers almost 71% of its surface. These are, in descending order by area, the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic Oceans. The word "sea" is often used interchangeably with "ocean" in American English but, strictly speaking, a sea is a body of saline water (generally a division of the world ocean) partly or fully enclosed by land., Subject: meda river, Relation: mouth_of_the_watercourse, Options: (A) arafura sea (B) arctic ocean (C) great australian bight (D) indian ocean (E) sea (F) southern ocean (G) timor sea

Context: Thunder Bay is a city in, and the seat of, Thunder Bay District, Ontario, Canada. It is the most populous municipality in Northwestern Ontario with a population of 108,359 as of the Canada 2011 Census, and the second most populous in Northern Ontario after Greater Sudbury. Located on Lake Superior, the census metropolitan area of Thunder Bay has a population of 121,596, and consists of the city of Thunder Bay, the municipalities of Oliver Paipoonge and Neebing, the townships of Shuniah, Conmee, O'Connor, and Gillies, and the Fort William First Nation., Montreal officially Montréal in both Canadian English and French, is the most populous municipality in Quebec and the 2nd-most populous in Canada. Originally called "Ville-Marie", or "City of Mary," it is named after Mount Royal, the triple-peaked hill in the heart of the city. The city is on the Island of Montreal, which took its name from the same source as the city, and a few much smaller peripheral islands, the largest of which is Île Bizard. It has a distinct four-season continental climate with warm to hot summers and cold snowy winters., The major professional sports leagues in the United States and Canada are the highest professional competitions of team sports in the United States and Canada. The four leagues universally included in the definition are Major League Baseball (MLB), the National Basketball Association (NBA), the National Football League (NFL), and the National Hockey League (NHL). Other prominent leagues include Major League Soccer (MLS) and the Canadian Football League (CFL)., The Governor General of Canada (French [masculine]: "Gouverneur général du Canada", or [feminine]: "Gouverneure générale du Canada") is the federal viceregal representative of the . Because the person of the sovereign is shared equally both with the 15 other Commonwealth realms and the 10 provinces of Canada and resides predominantly in oldest realm, the United Kingdom, , on the advice of the Canadian prime minister, appoints the governor general to carry out most of constitutional and ceremonial duties. The commission is for an unfixed period of timeknown as serving "at Majesty's pleasure"though five years is the normal convention. Beginning in 1959, it has also been traditional to rotate between anglophone and francophone incumbents. Once in office, the governor general maintains direct contact with the , wherever may be at the time., The Montreal Maroons (officially the Montreal Professional Hockey Club) were a professional men's ice hockey team in the National Hockey League (NHL). They played in the NHL from 1924 to 1938, winning the Stanley Cup in 1926 and 1935. They were the last non-Original Six team to win the Stanley Cup until the expansion Philadelphia Flyers won in 1974., Thomas John `` Tommy '' Cook ( May 7 , 1907 -- October 2 , 1961 ) was a professional Canadian ice hockey forward who played 348 games in the National Hockey League . Born in Fort William , Ontario , he played for the Montreal Maroons and Chicago Black Hawks . He won the Stanley Cup in 1934 with the Chicago Black Hawks ., A trophy is a tangible, durable reminder of a specific achievement, and serves as recognition or evidence of merit. Trophies are often awarded for sporting events, from youth sports to professional level athletics. In many sports medals (or, in North America, rings) are often given out either as the trophy or along with more traditional trophies., The Philadelphia Flyers are a professional ice hockey team based in Philadelphia, Pennsylvania. They are members of the Metropolitan Division of the Eastern Conference of the National Hockey League (NHL). Part of the 1967 NHL Expansion, the Flyers were the first expansion team in the post-Original Six era to win the Stanley Cup, victorious in 197374 and again in 197475., The Original Six is a term for the group of six teams that made up the National Hockey League (NHL) for the 25 seasons between the 194243 season and the 1967 NHL Expansion. These six teams are the Boston Bruins, Chicago Black Hawks, Detroit Red Wings, Montreal Canadiens, New York Rangers, and the Toronto Maple Leafs, all of which are still active franchises in the league. , Philadelphia is the largest city in the Commonwealth of Pennsylvania and the fifth-most populous city in the United States, with an estimated population of 1,567,442 and more than 6 million in the seventh-largest metropolitan statistical area, . Philadelphia is the economic and cultural anchor of the Delaware Valleya region located in the Northeastern United States at the confluence of the Delaware and Schuylkill rivers with 7.2 million people residing in the eighth-largest combined statistical area in the United States., Ice is water frozen into a solid state. Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color., Northern Ontario is a primary geographic and administrative region of the Canadian province of Ontario; the other primary region being Southern Ontario. The geographic region lies north of Lake Huron (including Georgian Bay), the French River, Lake Nipissing, and the Mattawa River, while the administrative region has several boundaries further south that vary according to federal and provincial government policies and requirements, such as a part of Nipissing District that lies south of the Mattawa River., Northwestern Ontario is a secondary region of Northern Ontario which lies north and west of Lake Superior, and west of Hudson Bay and James Bay. It includes most of subarctic Ontario. Its western boundary is the Canadian province of Manitoba, which disputed Ontario's claim to the western part of the region. Ontario's right to Northwestern Ontario was determined by the Judicial Committee of the Privy Council in 1884 and confirmed by the Canada (Ontario Boundary) Act, 1889 of the Parliament of the United Kingdom. In 1912, the Parliament of Canada by the Ontario Boundaries Extension Act gave jurisdiction over the District of Patricia to Ontario, thereby extending the northern boundary of the province to Hudson Bay., The Stanley Cup is the championship trophy awarded annually to the National Hockey League (NHL) playoff winner. Originally commissioned in 1892 as the "Dominion Hockey Challenge Cup", the trophy is named for Lord Stanley of Preston, thenGovernor General of Canada, who awarded it to Canada's top-ranking amateur ice hockey club, which the entire Stanley family supported, with the sons and daughters playing and promoting the game. The first Cup was awarded in 1893 to Montreal HC, and subsequent winners from 1893 to 1914 were determined by challenge games and league play. Professional teams first became eligible to challenge for the Stanley Cup in 1906. In 1915, the two professional ice hockey organizations, the National Hockey Association (NHA) and the Pacific Coast Hockey Association (PCHA), reached a gentlemen's agreement in which their respective champions would face each other annually for the Stanley Cup. After a series of league mergers and folds, it was established as the "de facto" championship trophy of the NHL in 1926 and then the "de jure" NHL championship prize in 1947., The City of New York, often called New York City or simply New York, is the most populous city in the United States. With an estimated 2015 population of 8,550,405 distributed over a land area of just , New York City is also the most densely populated major city in the United States. Located at the southern tip of the state of New York, the city is the center of the New York metropolitan area, one of the most populous urban agglomerations in the world. A global power city, New York City exerts a significant impact upon commerce, finance, media, art, fashion, research, technology, education, and entertainment, its fast pace defining the term "New York minute". Home to the headquarters of the United Nations, New York is an important center for international diplomacy and has been described as the cultural and financial capital of the world., The National Hockey Association (NHA), officially the "National Hockey Association of Canada Limited", was a professional ice hockey organization with teams in Ontario and Quebec, Canada. It is the direct predecessor to today's National Hockey League (NHL). Founded in 1909 by Ambrose O'Brien, the NHA introduced 'six-man hockey' by removing the 'rover' position in 1911. During its lifetime, the league coped with competition for players with the rival Pacific Coast Hockey Association (PCHA), the enlistment of players for World War I and disagreements between owners. The disagreements between owners came to a head in 1917, when the NHA suspended operations in order to get rid of an unwanted owner (Eddie Livingstone). The remaining NHA team owners started the NHL in parallel as a temporary measure, to continue play while negotiations went on with Livingstone and other lawsuits were pending. A year later, after no progress was reached with Livingstone, the other NHA owners decided to permanently suspend the NHA. The NHA's rules, constitution and trophies were continued in the NHL., Fort William was a city in Northern Ontario, located on the Kaministiquia River, at its entrance to Lake Superior. It amalgamated with Port Arthur and the townships of Neebing and McIntyre to form the city of Thunder Bay in January 1970. Since then it has been the largest city in Northwestern Ontario. The city's Latin motto was "A posse ad esse" (From a Possibility to an Actuality) featured on its coat of arms designed in 1900 by town officials, "On one side of the shield stands an Indian dressed in the paint and feathers of the early days; on the other side is a French voyageur; the center contains an elevator, a steamship and a locomotive, while the beaver surmounts the whole." , The Pacific Coast Hockey Association (PCHA) was a professional men's ice hockey league in western Canada and the western United States, which operated from 1911 to 1924 when it then merged with the Western Canada Hockey League (WCHL). The PCHA was considered to be a major league of ice hockey and was important in the development of the sport of professional ice hockey through its innovations., In ice hockey, the goaltender is the player responsible for preventing the hockey puck from entering their team's net, thus preventing the opposing team from scoring. The goaltender usually plays in or near the area in front of the net called the "goal crease" (often referred to simply as " the crease" or "the net"). Goaltenders tend to stay at or beyond the top of the crease to cut down on the angle of shots. In today's age of goaltending there are two common styles, butterfly and hybrid (hybrid is a mix of the traditional stand-up style and butterfly technique). Because of the power of shots, the goaltender wears special equipment designed to protect the body from direct impact. The goalie is one of the most valuable players on the ice, as their performance can greatly change the outcome or score of the game. One-on-one situations, such as breakaways and shootouts, have the tendency to highlight a goaltender's pure skill, or lack thereof. Only one goaltender is allowed to be on the ice for each team at any given time., Lake Superior is the largest of the Great Lakes of North America. The lake is shared by the Canadian province of Ontario to the north, the US state of Minnesota to the west, and Wisconsin and Michigan to the south. It is generally considered the largest freshwater lake in the world by surface area. It is the world's third-largest freshwater lake by volume and the largest by volume in North America., The Kaministiquia River is a river which empties into western Lake Superior at the city of Thunder Bay, Ontario. "Kaministiquia" ("Gaa-ministigweyaa") is an Ojibwe word meaning "(river) with islands" due to two large islands (McKellar and Mission) at the mouth of the river. The delta has three branches or outlets, reflected on early North American maps in French as "les trois rivières" (the three rivers): the southernmost is known as the Mission River, the central branch as the McKellar River, and the northernmost branch as the Kaministiquia. Residents of the region commonly refer to the river as the Kam River., Ice hockey is a contact team sport played on ice, usually in a rink, in which two teams of skaters use their sticks to shoot a vulcanized rubber puck into their opponent's net to score points. Ice hockey teams usually consist of six players each: one goaltender, and five players who skate up and down the ice trying to take the puck and score a goal against the opposing team., A gentlemen's agreement or gentleman's agreement is an informal and legally non-binding agreement between two or more parties. It is typically oral, though it may be written, or simply understood as part of an unspoken agreement by convention or through mutually beneficial etiquette. The essence of a gentlemen's agreement is that it relies upon the honor of the parties for its fulfillment, rather than being in any way enforceable. It is, therefore, distinct from a legal agreement or contract, which can be enforced if necessary., The National Hockey League (NHL) is a professional ice hockey league currently composed of 31 member clubs. Of the 30 clubs currently playing, 23 are in the United States and 7 in Canada. Headquartered in New York City, the NHL is considered to be the premier professional ice hockey league in the world, and one of the major professional sports leagues in the United States and Canada. The Stanley Cup, the oldest professional sports trophy in North America, is awarded annually to the league playoff champion at the end of each season., A team sport includes any sport which involves two or more players working together towards a shared objective. A team sport is an activity in which individuals are organized into opposing teams which compete to win. Examples are basketball, volleyball, water polo, handball, lacrosse, cricket, baseball, and the various forms of football and hockey., Subject: tom cook, Relation: place_of_birth, Options: (A) 1942 (B) arthur (C) boston (D) canada (E) canadian (F) center (G) chicago (H) commerce (I) council (J) delaware (K) fort william (L) freshwater (M) hill (N) hudson bay (O) legal (P) manitoba (Q) mary (R) michigan (S) minnesota (T) montreal (U) montréal (V) new york city (W) normal (X) of (Y) once (Z) ontario ([) oral (\) pacific (]) pennsylvania (^) philadelphia (_) polo (`) port arthur (a) preston (b) puck (c) quebec (d) stanley (e) sudbury (f) superior (g) thunder bay (h) united kingdom (i) winner

Context: Chaetodon is a tropical fish genus in the family Chaetodontidae. Like their relatives, they are known as "butterflyfish". This genus is by far the largest among the Chaetodontidae, with about 90 living species included here, though most might warrant recognition as distinct genera., In biology, an organism is any contiguous living system, such as an animal, plant, fungus, archaeon, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms. Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs., Underwater diving is the practice of descending below the water's surface to conduct underwater activities. In ambient pressure diving, the diver is exposed to the pressure of the surrounding water, and uses breathing apparatus for scuba diving or surface supplied diving, or when freediving, will breath-hold. The saturation diving technique reduces the risk of decompression sickness after long duration deep dives. Atmospheric diving suits may be used to isolate the diver from the effects of high ambient pressure. Although not usually considered to be diving, crewed submersibles can extend depth range, while remotely controlled or robotic diving machines can reduce the risk to human divers., Scuba diving is a mode of underwater diving in which the scuba diver uses a self-contained underwater breathing apparatus (scuba) which is completely independent of surface supply, to breathe underwater. Scuba provides the diver with the advantages of mobility and horizontal range far beyond the reach of an umbilical hose attached to surface-supplied diving equipment (SSDE).
Scuba divers engaged in armed forces covert operations may be referred to as frogmen, combat divers or attack swimmers., Prognathodes is a genus of butterflyfishes . In the past they were commonly included in the genus Chaetodon . They are found at rocky reefs in tropical oceans around the world , and are mainly found deeper than Chaetodon ; often a depths below those possible in normal scuba diving . They are whitish , yellow , black and dark brown , and reach 10 -- 16 centimetres ( 3.9 -- 6.3 in ) in length ., A genus ( genera) is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus., Binomial nomenclature (also called binominal nomenclature or binary nomenclature) is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. For example, humans belong to the genus "Homo" and within this genus to the species "Homo sapiens". The "formal" introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work "Species Plantarum" in 1753. But Gaspard Bauhin, in as early as 1623, had introduced in his book "Pinax theatri botanici" (English, "Illustrated exposition of plants") many names of genera that were later adopted by Linnaeus., Subject: prognathodes, Relation: parent_taxon, Options: (A) animal (B) chaetodon (C) chaetodontidae (D) dives (E) homo
