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

Context: The New South Wales Legislative Council, or upper house, is one of the two chambers of the parliament of the Australian state of New South Wales. The other is the Legislative Assembly. Both sit at Parliament House in the state capital, Sydney. The Assembly is referred to as the lower house and the Council as the upper house. It is normal for legislation to be first deliberated on and enacted in the lower house, and then considered in the upper house, which acts in the main as a house of review. The Council has 42 members, elected by proportional representation in which the whole state is treated as a single electorate. Members serve eight-year terms, which are staggered so that half the Council is up for election every four yearsroughly coinciding with elections to the Legislative Assembly., The Australian Senate is the upper house of the bicameral Parliament of Australia, the lower house being the House of Representatives. The composition and powers of the Senate are established in Chapter I, Part II of the Australian Constitution. There are a total of 76 senators: 12 senators are elected from each of the six states (regardless of population) and two from each of the two autonomous internal territories (the Australian Capital Territory and the Northern Territory). Senators are popularly elected under the single transferable vote system of proportional representation. , Elaine Blanche Nile ( 20 March 1936 -- 17 October 2011 ) was an Australian politician who represented the Christian Democratic Party in the New South Wales Legislative Council between 1998 and 2002 . Nile was married to Fred Nile from 1958 until her death ., New South Wales (abbreviated as NSW) is a state on the east coast of :Australia. It borders Queensland to the north, Victoria to the south, and South Australia to the west. It has a coast line with the Tasman Sea on its east side. The Australian Capital Territory is an enclave within the state. New South Wales' state capital is Sydney, which is also Australia's most populous city. , the estimated population of New South Wales was 7.5 million, making it Australia's most populous state. Just under two-thirds of the state's population, 4.67 million, live in the Greater Sydney area. Inhabitants of New South Wales are referred to as "New South Welshmen"., Frederick John "Fred" Nile ED MLC (born 15 September 1934) is an Australian politician and ordained Christian minister. Nile has been a member of the New South Wales Legislative Council since 1981, except for a period in 2004 when he resigned to unsuccessfully contest the Australian Senate at the 2004 federal election. Nile was re-elected at the March 2007 state election and is currently Assistant President of the Legislative Council. He is the longest-serving member of the New South Wales parliament. In November 2009 he stated his decision to retire in 2015, but later announced his decision to accept the Christian Democratic Party (CDP) nomination for the NSW Legislative Council at the New South Wales State Election on 28 March 2015., Subject: elaine nile, Relation: position_held, Options: (A) 12 (B) 15 (C) 4 (D) member of the new south wales legislative council (E) new south wales legislative council (F) politician (G) senate

Context: Heme or haem (from Greek "haima" meaning blood) is a cofactor consisting of an Fe (ferrous) ion contained in the centre of a heterocyclic macrocycle organic compound called a porphyrin, made up of four pyrrolic groups joined together by methine bridges. Not all porphyrins contain iron, but a substantial fraction of porphyrin-containing metalloproteins have heme as their prosthetic group; these are known as hemoproteins. Hemes are most commonly recognized as components of hemoglobin, the red pigment in blood, but are also found in a number of other biologically important hemoproteins such as myoglobin, cytochrome, catalase, heme peroxidase, and endothelial nitric oxide synthase., Hemodialysis, also spelled haemodialysis, commonly called kidney dialysis or simply dialysis, is a process of purifying the blood of a person whose kidneys are not working normally. This type of dialysis achieves the extracorporeal removal of waste products such as creatinine and urea and free water from the blood when the kidneys are in a state of kidney failure. Hemodialysis is one of three renal replacement therapies (the other two being kidney transplant and peritoneal dialysis). An alternative method for extracorporeal separation of blood components such as plasma or cells is apheresis., A disease is a particular abnormal condition, a disorder of a structure or function, that affects part or all of an organism. The study of disease is called pathology which includes the causal study of etiology. Disease is often construed as a medical condition associated with specific symptoms and signs. It may be caused by external factors such as pathogens, or it may be caused by internal dysfunctions particularly of the immune system such as an immunodeficiency, or a hypersensitivity including allergies and autoimmunity., Creatinine (or ; from ) is a breakdown product of creatine phosphate in muscle, and is usually produced at a fairly constant rate by the body (depending on muscle mass)., Porphyria is a group of diseases in which substances called porphyrins build up, affecting the skin or nervous system. The types that affect the nervous system are also known as acute porphyria. Symptoms of acute porphyria include abdominal pain, chest pain, vomiting, confusion, constipation, fever, and seizures. These symptoms typically come and go with attacks that last for days to weeks. Attacks may be triggered by alcohol, smoking, stress, or certain medications. If the skin is affected, blisters or itching may occur with sunlight exposure.
The disease is usually inherited from a person's parents and is due to a mutation in one of the genes that make heme. Some types are autosomal dominant and others are autosomal recessive. One type, porphyria cutanea tarda, may also be due to increased iron in the liver, hepatitis C, alcohol, or HIV/AIDS. The underlying mechanism results in a decrease in the amount of heme produced and a build-up of substances involved in making heme. Porphyrias may also be classified by whether the liver or the bone marrow is affected. Diagnosis is typically by blood, urine, and stool tests. Genetic testing may be done to determine the specific mutation.
Treatment depends on the type of porphyria and a person's symptoms. The treatment of porphyria of the skin generally involves the avoidance of sunlight. The treatment for acute porphyria may involve giving intravenous heme or a glucose solution. Rarely a liver transplant may be carried out.
The frequency of porphyria is unclear. It is estimated that it affects 1 to 100 per 50,000 people. Rates vary around the world. Porphyria cutanea tarda is believed to be the most common type. The disease was described at least as early as 370 BC by Hippocrates. The underlying mechanism was first described by Felix Hoppe-Seyler in 1871. The name "porphyria" is from the Greek , "porphyra", meaning "purple", a reference to the color of the urine that may occur during an attack. , Enzymes are macromolecular biological catalysts. Enzymes accelerate, or catalyze, chemical reactions. The molecules at the beginning of the process upon which enzymes may act are called substrates and the enzyme converts these into different molecules, called products. Almost all metabolic processes in the cell need enzymes in order to occur at rates fast enough to sustain life. The set of enzymes made in a cell determines which metabolic pathways occur in that cell. The study of enzymes is called "enzymology"., The kidneys are two bean-shaped organs found on the left and right sides of the body in vertebrates. They filter the blood in order to make urine, to release and retain water, and to remove waste. They also control the ion concentrations and acid-base balance of the blood. Each kidney feeds urine into the bladder by means of a tube known as the ureter., Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells., Urea, also known as carbamide, is an organic compound with the chemical formula CO(NH). This amide has two NH groups joined by a carbonyl (C=O) functional group., Skin is the soft outer covering of vertebrates. Other animal coverings, such as the arthropod exoskeleton have different developmental origin, structure and chemical composition. The adjective cutaneous means "of the skin" (from Latin "cutis", skin). In mammals, the skin is an organ of the integumentary system made up of multiple layers of ectodermal tissue, and guards the underlying muscles, bones, ligaments and internal organs. Skin of a different nature exists in amphibians, reptiles, and birds. All mammals have some hair on their skin, even marine mammals like whales, dolphins, and porpoises which appear to be hairless.
The skin interfaces with the environment and is the first line of defense from external factors. For example, the skin plays a key role in protecting the body against pathogens and excessive water loss. Its other functions are insulation, temperature regulation, sensation, and the production of vitamin D folates. Severely damaged skin may heal by forming scar tissue. This is sometimes discoloured and depigmented. The thickness of skin also varies from location to location on an organism. In humans for example, the skin located under the eyes and around the eyelids is the thinnest skin in the body at 0.5 mm thick, and is one of the first areas to show signs of aging such as "crows feet" and wrinkles. The skin on the palms and the soles of the feet is 4 mm thick and the back is 14 mm thick and is the thickest skin in the body. The speed and quality of wound healing in skin is promoted by the reception of estrogen., An extracorporeal medical procedure is a medical procedure which is performed outside the body., Apheresis ( ("aphairesis", "a taking away")) is a medical technology in which the blood of a person is passed through an apparatus that separates out one particular constituent and returns the remainder to the circulation. It is thus an extracorporeal therapy., In medicine, dialysis (from Greek , "diàlysis", meaning "dissolution", , "dià", meaning "through", and , "lsis", meaning "loosening or splitting") is a process for removing waste and excess water from the blood and is used primarily as an artificial replacement for lost kidney function in people with kidney failure. Dialysis may be used for those with an acute disturbance in kidney function (acute kidney injury, previously acute renal failure) or progressive but chronically worsening kidney functiona state known as chronic kidney disease stage 5 (previously chronic kidney failure or end-stage renal disease). The latter form may develop over months or years, but in contrast to acute kidney injury is not usually reversible and dialysis is regarded as a "holding measure" until a kidney transplant can be performed or sometimes as the only supportive measure in those for whom a transplant would be inappropriate., Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetal and oxidizing agent that readily forms oxides with most elements as well as other compounds. By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula . This is an important part of the atmosphere and diatomic oxygen gas constitutes 20.8% of the Earth's atmosphere. Additionally, as oxides the element makes up almost half of the Earth's crust., Porphyria cutanea tarda (PCT) is the most common subtype of porphyria. The disease is named because it is a porphyria that often presents with skin manifestations later in life. The disorder results from low levels of the enzyme responsible for the fifth step in heme production. Heme is a vital molecule for all of the body's organs. It is a component of hemoglobin, the molecule that carries oxygen in the blood., Pseudoporphyria ( also known as `` Pseudoporphyria cutanea tarda '' ) is a bullous photosensitivity that clinically and histologically mimics porphyria cutanea tarda . The difference is that no abnormalities in urine or serum porphyrin is noted on laboratories . Pseudoporphyria has been reported in patients with chronic renal failure treated with hemodialysis and in those with excessive exposure to ultraviolet A ( UV - A ) by tanning beds ., Kidney failure, also known as renal failure or renal insufficiency, is a medical condition of impaired kidney function in which the kidneys fail to adequately filter metabolic wastes from the blood. The two main forms are acute kidney injury, which is often reversible with adequate treatment, and chronic kidney disease, which is often not reversible. In both cases, there is usually an underlying cause., Hemoglobin; also spelled haemoglobin (United Kingdom spelling) and abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein in the red blood cells of all vertebrates (with the exception of the fish family Channichthyidae) as well as the tissues of some invertebrates. Hemoglobin in the blood carries oxygen from the respiratory organs (lungs or gills) to the rest of the body (i.e. the tissues). There it releases the oxygen to permit aerobic respiration to provide energy to power the functions of the organism in the process called metabolism., Subject: pseudoporphyria, Relation: instance_of, Options: (A) adjective (B) animal (C) atmosphere (D) base (E) body fluid (F) cell (G) chemical (H) chemical element (I) chest (J) component (K) composition (L) condition (M) dioxygen (N) disease (O) environment (P) failure (Q) filter (R) fish (S) fluid (T) formula (U) frequency (V) function (W) functional group (X) group (Y) hepatitis (Z) hydrogen ([) injury (\) ion (]) line (^) location (_) mass (`) may (a) medicine (b) member (c) metabolism (d) order (e) organ (f) organic compound (g) organism (h) part (i) person (j) phosphate (k) procedure (l) process (m) product (n) production (o) role (p) set (q) show (r) skin (s) stage (t) standard (u) structure (v) subtype (w) technology (x) temperature (y) three (z) tissue ({) transport (|) treatment (}) two
