Example Input: Context: Didymosphenia geminata, commonly known as didymo or rock snot, is a species of diatom that produces nuisance growths in freshwater rivers and streams with consistently cold water temperatures and low nutrient levels. It is native to the northern hemisphere, and considered an invasive species in Australia, Argentina, New Zealand, and Chile. Even within its native range, it has taken on invasive characteristics since the 1980s. It is not considered a significant human health risk, but it can affect stream habitats and sources of food for fish and make recreational activities unpleasant. This microscopic alga can be spread in a single drop of water., The South Island or Te Waipounamu ("Mori") is the larger of the two major islands of New Zealand, the other being the smaller but more populous North Island. It is bordered to the north by Cook Strait, to the west by the Tasman Sea, and to the south and east by the Pacific Ocean. The South Island covers and is influenced by a temperate climate., Benmore Dam is the largest dam within the Waitaki power scheme, located in the Canterbury Region of New Zealand's South Island. There are eight other power stations in the Waitaki Power Scheme., Auckland is a city in the North Island of New Zealand. It is the most populous urban area in the country. Auckland has a population of , which constitutes percent of New Zealand's population. It is part of the wider Auckland Regionthe area governed by the Auckland Councilwhich also includes outlying rural areas and the islands of the Hauraki Gulf, resulting in a total population of . Auckland also has the largest Polynesian population of any city in the world. The Mori language name for Auckland is or , meaning "Tmaki with a hundred lovers", in reference to the desirability of its fertile land at the hub of waterways in all directions. It has also been called karana, the Mori enunciation of "Auckland"., The North Island or Te Ika-a-Mui ("Mori") is one of the two main islands of New Zealand, separated from the slightly larger but much less populous South Island by Cook Strait. The island's area is , making it the world's 14th-largest island. It has a population of , Lake Pukaki is the largest of three roughly parallel alpine lakes running north-south along the northern edge of the Mackenzie Basin on New Zealand's South Island. The others are Lakes Tekapo and Ohau. All three lakes were created when the terminal moraines of receding glaciers blocked their respective valleys, forming moraine-dammed lakes., The Pukaki River flows through the Mackenzie Basin, Canterbury, in New Zealand's South Island., Lake Benmore is a lake located in the South Island of New Zealand. It was artificially created in the 1960s by construction of Benmore Dam. The lake covers an area of approximately 75 km². Parts of it lie in the Mackenzie, Waimate, and Waitaki districts within the southern portion of the Canterbury Region., The Mackenzie Basin (popularly and traditionally known as the Mackenzie Country) is an elliptical intermontane basin located in the Mackenzie and Waitaki Districts, near the centre of the South Island of New Zealand. It is the largest such basin in New Zealand. Historically famous mainly for sheep farming, the sparsely populated area is now also a popular tourism destination., In geography, temperate or tepid latitudes of Earth lie between the tropics and the polar regions. The temperatures in these regions are generally relatively moderate, rather than extremely hot or cold, and the changes between summer and winter are also usually moderate., Lake Tekapo is the second-largest of three roughly parallel lakes running northsouth along the northern edge of the Mackenzie Basin in the South Island of New Zealand (the others are Lake Pukaki and Lake Ohau). It covers an area of , and is at an altitude of above sea level., Diatoms are a major group of algae, and are among the most common types of phytoplankton. Diatoms are unicellular, although they can form colonies in the shape of filaments or ribbons (e.g. "Fragilaria"), fans (e.g. "Meridion"), zigzags (e.g. "Tabellaria"), or stars (e.g. "Asterionella"). The first diatom formally described in scientific literature, the colonial "Bacillaria paradoxa", was found in 1783 by Danish naturalist Otto Friedrich Müller. Diatoms are producers within the food chain. A unique feature of diatom cells is that they are enclosed within a cell wall made of silica (hydrated silicon dioxide) called a frustule. These frustules show a wide diversity in form, but are usually almost bilaterally symmetrical, hence the group name. The symmetry is not perfect since one of the valves is slightly larger than the other, allowing one valve to fit inside the edge of the other. Fossil evidence suggests that they originated during, or before, the early Jurassic period. Only male gametes of centric diatoms are capable of movement by means of flagella. Diatom communities are a popular tool for monitoring environmental conditions, past and present, and are commonly used in studies of water quality., New Zealand is an island nation in the southwestern Pacific Ocean. The country geographically comprises two main landmassesthat of the North Island, or Te Ika-a-Mui, and the South Island, or Te Waipounamuand numerous smaller islands. New Zealand is situated some east of Australia across the Tasman Sea and roughly south of the Pacific island areas of New Caledonia, Fiji, and Tonga. Because of its remoteness, it was one of the last lands to be settled by humans. During its long period of isolation, New Zealand developed a distinct biodiversity of animal, fungal and plant life. The country's varied topography and its sharp mountain peaks, such as the Southern Alps, owe much to the tectonic uplift of land and volcanic eruptions. New Zealand's capital city is Wellington, while its most populous city is Auckland., Cook Strait lies between the North and South Islands of New Zealand. It connects the Tasman Sea on the northwest with the South Pacific Ocean on the southeast, and runs next to the capital city, Wellington. It is wide at its narrowest point, and is considered one of the most dangerous and unpredictable waters in the world., A moraine is any glacially formed accumulation of unconsolidated glacial debris (soil and rock) that occurs in both currently and formerly glaciated regions on Earth (i.e. a past glacial maximum), through geomorphological processes. Moraines are formed from debris previously carried along by a glacier and normally consist of somewhat rounded particles ranging in size from large boulders to minute glacial flour. Lateral moraines are formed at the side of the ice flow and terminal moraines at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines, till-covered areas with irregular topography, and medial moraines which are formed where two glaciers meet., New Caledonia is a special collectivity of France located in the southwest Pacific Ocean, east of Australia and east of Metropolitan France. The archipelago, part of the Melanesia subregion, includes the main island of Grande Terre, the Loyalty Islands, the Chesterfield Islands, the Belep archipelago, the Isle of Pines, and a few remote islets. The Chesterfield Islands are in the Coral Sea. Locals refer to Grande Terre as "" ("the pebble")., Fiji ((), officially the Republic of Fiji, is an island country in Melanesia in the South Pacific Ocean about northeast of New Zealand's North Island. Its closest neighbours are Vanuatu to the west, New Caledonia to the southwest, New Zealand's Kermadec Islands to the southeast, Tonga to the east, the Samoas and France's Wallis and Futuna to the northeast, and Tuvalu to the north., A moraine-dammed lake occurs when the terminal moraine has prevented some meltwater from leaving the valley. Its most common shape is that of a long ribbon (ribbon lake). 
Example of moraine dammed lakes include:, Climate is the statistics of weather, usually over a 30-year interval. It is measured by assessing the patterns of variation in temperature, humidity, atmospheric pressure, wind, precipitation, atmospheric particle count and other meteorological variables in a given region over long periods of time. Climate differs from weather, in that weather only describes the short-term conditions of these variables in a given region., The Pacific Ocean is the largest of the Earth's oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south and is bounded by Asia and Australia in the west and the Americas in the east., Chile, officially the Republic of Chile, is a South American country occupying a long, narrow strip of land between the Andes to the east and the Pacific Ocean to the west. It borders Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage in the far south. Chilean territory includes the Pacific islands of Juan Fernández, Salas y Gómez, Desventuradas, and Easter Island in Oceania. Chile also claims about of Antarctica, although all claims are suspended under the Antarctic Treaty., Sheep rearing is the raising and breeding of domestic sheep. It is a branch of animal husbandry. Sheep are raised principally for their meat (lamb and mutton), milk (sheep's milk), and fiber (wool). They also yield sheepskin and parchment., Rats are various medium-sized, long-tailed rodents of the superfamily Muroidea. "True rats" are members of the genus "Rattus", the most important of which to humans are the black rat, "Rattus rattus", and the brown rat, "Rattus norvegicus". Many members of other rodent genera and families are also referred to as rats, and share many characteristics with true rats., A habitat is an ecological or environmental area that is inhabited by a particular species of animal, plant, or other type of organism. The term typically refers to the zone in which the organism lives and where it can find food, shelter, protection and mates for reproduction. It is the natural environment in which an organism lives, or the physical environment that surrounds a species population., Australia, officially the Commonwealth of Australia, is a country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the world's sixth-largest country by total area. The neighbouring countries are Papua New Guinea, Indonesia and East Timor to the north; the Solomon Islands and Vanuatu to the north-east; and New Zealand to the south-east. Australia's capital is Canberra, and its largest urban area is Sydney., The Tekapo River flows occasionally through the Mackenzie Basin , Canterbury , in New Zealand 's South Island , although the riverbed is now often dry in the upper reaches . It maintains a constant flow below the confluence of several tributaries , notably the Merryburn , Forks , and Greys streams . The lower reaches ( below the Merryburn confluence ) are popular with anglers chasing brown and rainbow trout , although recent infestation by the invasive algae didymo ( Didymosphenia geminata ) has somewhat limited angling opportunities . Originally , the river flowed southwest for 25 kilometres ( 16 mi ) from the southern end of Lake Tekapo before joining with the Pukaki River and flowing into the northern end of Lake Benmore . However , the water from Lake Tekapo is now diverted via a canal to Lake Pukaki as part of the Waitaki hydroelectric scheme . These lakes are used to store water , and occasionally during a particularly heavy snow melt or if the power stations or canal need servicing , water may be spilt from either the dam or canal back into the riverbed . These events are much anticipated by kayakers , to the extent that they have been known to re-shape parts of the riverbed to create `` better '' rapids ., Intermontane is a physiographic adjective formed from the prefix "inter-" (""signifying among, between, amid, during, within, mutual, reciprocal") and the adjective "montane" (""inhabiting, or growing in mountainous regions, especially cool, moist upland slopes below the timberline."") , Tonga (or ; Tongan: "Puleanga Fakatui o Tonga"), officially the Kingdom of Tonga, is a Polynesian sovereign state and archipelago comprising 169 islands of which 36 are inhabited. The total surface area is about scattered over of the southern Pacific Ocean. It has a population of 103,000 people of whom 70% reside on the main island of Tongatapu., A lake is an area of variable size filled with water, localized in a basin, that is surrounded by land, apart from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, and therefore are distinct from lagoons, and are also larger and deeper than ponds, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which are usually flowing. Most lakes are fed and drained by rivers and streams., The Waitaki district, in the Canterbury and Otago regions of New Zealand, straddles the traditional border between the two regions, the Waitaki River., The Southern Alps (Mori: K Tiritiri o te Moana ) are a mountain range extending along much of the length of New Zealand's South Island, reaching its greatest elevations near the island's western side. The term "Southern Alps" generally refers to the entire range, although separate names are given to many of the smaller ranges that form part of it., The Tasman Sea (Mori: "Te Tai-o-Rehua") is a marginal sea of the South Pacific Ocean, situated between Australia and New Zealand. It measures about across and about from north to south. The sea was named after the Dutch explorer Abel Janszoon Tasman, who was the first recorded European to encounter New Zealand and Tasmania. The British explorer Captain James Cook later extensively navigated the Tasman Sea in the 1770s as part of his first voyage of exploration., Wellington is the capital city and second most populous urban area of New Zealand, with residents. It is at the south-western tip of the North Island, between Cook Strait and the Rimutaka Range. Wellington is the major population centre of the southern North Island and is the administrative centre of the Wellington Region, which also includes the Kapiti Coast and Wairarapa. As the nation's capital city, the New Zealand Government and Parliament, Supreme Court and most of the civil service are based in the city., Tectonic uplift is the portion of the total geologic uplift of the mean Earth surface that is not attributable to an isostatic response to unloading. While isostatic response is important, an increase in the mean elevation of a region can only occur in response to tectonic processes of crustal thickening (such as mountain building events), changes in the density distribution of the crust and underlying mantle, and flexural support due to the bending of rigid lithosphere., Subject: tekapo river, Relation: located_in_the_administrative_territorial_entity, Options: (A) alpine (B) argentina (C) auckland (D) auckland region (E) australia (F) basin (G) bolivia (H) caledonia (I) canberra (J) canterbury region (K) chile (L) district (M) earth (N) fiji (O) futuna (P) hot (Q) indonesia (R) lakes (S) loyalty islands (T) mainland (U) metropolitan france (V) most (W) mountain (X) new zealand (Y) north (Z) north island ([) northwest (\) of (]) pacific ocean (^) papua (_) river (`) rock (a) solomon islands (b) south (c) southwest (d) sydney (e) tasmania (f) the valley (g) three lakes (h) time (i) tonga (j) tongatapu (k) upland (l) waitaki district (m) wallis (n) wallis and futuna (o) wellington

The conference name is also commonly used to refer to those eight schools as a group beyond the sports context. The eight institutions are Brown University, Columbia University, Cornell University, Dartmouth College, Harvard University, the University of Pennsylvania, Princeton University, and Yale University. The term "Ivy League" has connotations of academic excellence, selectivity in admissions, and social elitism., Columbia University (officially Columbia University in the City of New York) is a private Ivy League research university in Upper Manhattan, New York City. It was established in 1754 as King's College by royal charter of George II of Great Britain. Columbia is the oldest college in the state of New York and the fifth chartered institution of higher learning in the country, making it one of nine colonial colleges founded before the Declaration of Independence. After the American Revolutionary War, King's College briefly became a state entity, and was renamed Columbia College in 1784. A 1787 charter placed the institution under a private board of trustees before it was renamed Columbia University in 1896 when the campus was moved from Madison Avenue to its current location in Morningside Heights occupying of land. Columbia is one of the fourteen founding members of the Association of American Universities, and was the first school in the United States to grant the M.D. degree., A royal charter is a formal document issued by a monarch as letters patent, granting a right or power to an individual or a body corporate. They were, and are still, used to establish significant organisations such as cities (with municipal charters) or universities and learned societies. Charters should be distinguished from warrants and letters of appointment, as they have perpetual effect. Typically, a Royal Charter is produced as a high-quality work of calligraphy on vellum. The British monarchy has issued over 980 royal charters. Of these about 750 remain in existence. The earliest was to the town of Tain in 1066, making it the oldest Royal Burgh in Scotland, followed by the University of Cambridge in 1231. Charters continue to be issued by the British Crown, a recent example being that awarded to the Chartered Institute for the Management of Sport and Physical Activity, on 7 April 2011., Guillermo Antonio Calvo ( born 1941 ) is an Argentine - American economist who is Director of Columbia University 's mid-career Program in Economic Policy Management in their School of International and Public Affairs ( SIPA ) .
