Q: Context: Korea is a historical state in East Asia, since 1945 divided into two distinct sovereign states: North Korea (officially the "Democratic People's Republic of Korea") and South Korea (officially the "Republic of Korea"). Located on the Korean Peninsula, Korea is bordered by China to the northwest and Russia to the northeast. It is separated from Japan to the east by the Korea Strait and the East Sea., Rikishi () is the Japanese term for a professional sumo wrestler. The two kanji characters that make up the word are "strength/power" and "gentleman/samurai"; consequently, and more idiomatically, 'a gentleman of strength'. This is reflective of the strength and toughness expected of a sumo wrestler and the gentleman samurai image still afforded to sumo wrestlers who have continued into modern times to dress as the samurai of old., The calls a professional sumo wrestler, or "rikishi", to the "dohy" (wrestling ring) immediately prior to his bout. He does this by calling the name of each wrestler fighting in turn whilst holding a traditional folding fan., The is the body that operates and controls professional sumo wrestling in Japan under the jurisdiction of the Japanese Ministry of Education, Culture, Sports, Science and Technology. "Rikishi" (active wrestlers), "gyji" (referees), "tokoyama" (hairdressers), and "yobidashi" (ushers/handymen), are all on the Association's payroll, but the organisation is run entirely by "toshiyori" (elders). The organization has its headquarters in Yokoami, Sumida, Tokyo., Taiwan, officially the Republic of China (ROC), is a state in East Asia. Neighbors include China (officially the People's Republic of China, abbreviated as PRC) to the west, Japan to the northeast, and the Philippines to the south.
Taiwan is the most populous state that is not a member of the United Nations, and the one with the largest economy., Tokyo, officially Tokyo Metropolis, is the capital of Japan and one of its 47 prefectures. The Greater Tokyo Area is the most populous metropolitan area in the world. It is the seat of the Emperor of Japan and the Japanese government. Tokyo is in the Kant region on the southeastern side of the main island Honshu and includes the Izu Islands and Ogasawara Islands. Formerly known as Edo, it has been the de facto seat of government since 1603 when Shogun Tokugawa Ieyasu made the city his headquarters. It officially became the capital after Emperor Meiji moved his seat to the city from the old capital of Kyoto in 1868; at that time Edo was renamed Tokyo. Tokyo Metropolis was formed in 1943 from the merger of the former and the ., A ritual "is a sequence of activities involving gestures, words, and objects, performed in a sequestered place, and performed according to set sequence." Rituals may be prescribed by the traditions of a community, including a religious community. Rituals are characterized but not defined by formalism, traditionalism, invariance, rule-governance, sacral symbolism, and performance., Japan ("Nippon" or "Nihon" ; formally "" or "Nihon-koku", means "State of Japan") is a sovereign island nation in Eastern Asia. Located in the Pacific Ocean, It is lying off the eastern coast of the Asia Mainland (east of China, Korea, Russia) and stretching from the Sea of Okhotsk in the north to the East China Sea and near Taiwan in the southwest. , Sadanoyama Shinmatsu (   , born February 18 , 1938 as Shinmatsu Sasada ) is a former sumo wrestler from Nagasaki Prefecture , Japan . He was the sport 's 50th yokozuna . After his retirement he was the head coach of Dewanoumi stable and served as head of the Japan Sumo Association ., China, officially the People's Republic of China (PRC), is a unitary sovereign state in East Asia. With a population of over 1.381 billion, it is the world's most populous country. The state is governed by the Communist Party of China, and its capital is Beijing. It exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities (Beijing, Tianjin, Shanghai, and Chongqing), and two mostly self-governing special administrative regions (Hong Kong and Macau), and claims sovereignty over Taiwan. The country's major urban areas include Shanghai, Guangzhou, Beijing, Chongqing, Shenzhen, Tianjin and Hong Kong. China is a great power and a major regional power within Asia, and has been characterized as a potential superpower., A tokoyama () is a hairdresser employed by the Japan Sumo Association to cut and prepare sumo wrestlers' hair, which is done in a "chonmage" style. The Sumo Association ranks them according to experience and ability and only the most senior "tokoyama" are entitled to prepare the more ornate "oicho", or ginkgo leaf form of topknot, which "sekitori" ranked wrestlers wear in their bouts and on other formal occasions. It may not seem to the casual observer that such a position is necessary, but the elaborate hairstyle of sumo wrestlers, especially "sekitori", combined with the combative nature of sumo bouts and sumo practice make it necessary for these professionals to be on hand to maintain the topknots as they are expected to look., The sport originated in Japan, the only country where it is practiced professionally. It is generally considered a "gendai bud" (a modern Japanese martial art), but this definition is misleading, as the sport has a history spanning many centuries.
Many ancient traditions have been preserved in sumo, and even today the sport includes many ritual elements, such as the use of salt purification, from the days when sumo was used in the Shinto religion. Life as a wrestler is highly regimented, with rules regulated by the Japan Sumo Association. Most sumo wrestlers are required to live in communal sumo training stables, known in Japanese as "heya", where all aspects of their daily livesfrom meals to their manner of dressare dictated by strict tradition., A Gyji () is a referee in professional sumo wrestling in Japan., The demotion of Futen to the "makushita" division in July 2010 left the stable without any "sekitori" (wrestlers in the salaried divisions) for the first time since 1898. This continued until Dewahayate was promoted to the "juryo" division for the November 2014 tournament (in which he managed only 5 wins and was immediately demoted). In January 2015 the stable saw ex-"maegashira" Towanoyama announce his retirement, leaving Dewaotori and the 44-year-old Dewanosato, with four tournament in "juryo" between them, as the only other wrestlers apart from Dewahayate with any "sekitori" experience. However shortly afterwards the stable recruited former amateur "yokozuna" Mitakeumi who quickly made "juryo" in July 2015 and the top "makuuchi" division in January 2016. , A sekitori () is a "rikishi" (sumo wrestler) who is ranked in one of the top two professional divisions: "makuuchi" and "jry". 
The name literally translates to having taken the barrier, as only a relatively small fraction of those who enter professional sumo achieve "sekitori" status., Russia (from the  Rus'), also officially known as the Russian Federation, is a country in Eurasia. At , Russia is the largest country in the world by surface area, covering more than one-eighth of the Earth's inhabited land area, and the ninth most populous, with over 140 million people at the end of March 2016. The European western part of the country is much more populated and urbanised than the eastern, about 77% of the population live in European Russia. Russia's capital Moscow is one of the largest cities in the world, other major urban centers include Saint Petersburg, Novosibirsk, Yekaterinburg, Nizhny Novgorod and Samara., Subject: sadanoyama shinmatsu, Relation: occupation, Options: (A) emperor (B) hairdresser (C) major (D) ministry (E) referee (F) religion (G) religious (H) rikishi (I) saint (J) sovereign (K) taiwan

A: rikishi

Q: Context: 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., 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., Labroides is a genus of wrasses native to the Indian and Pacific Oceans . This genus is collectively known as cleaner wrasses and its species are cleaner fish ., 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., 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., Cleaner shrimp is a common name for a number of swimming decapod crustaceans that clean other organisms of parasites. They belong to any of three families, Hippolytidae (including the Pacific cleaner shrimp, "Lysmata amboinensis"), Palaemonidae (including the spotted "Periclimenes magnificus") and Stenopodidae (including the banded coral shrimp, "Stenopus hispidus") . The last of these families is more closely related to lobsters and crabs than it is to the remaining families. The term "cleaner shrimp" is sometimes used more specifically for the family Hippolytidae and the genus "Lysmata"., Cichlids are fish from the family Cichlidae in the order Perciformes. Cichlids are members of a suborder known as Labroidei, along with the wrasses (Labridae), damselfishes (Pomacentridae), and surfperches (Embiotocidae). This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Cichlids are popular freshwater fish kept in the home aquarium., Cleaner fish are fish that provide a service to other fish species by removing dead skin and ectoparasites. This cleaning symbiosis is an example of mutualism, an ecological interaction that benefits both parties involved. However, the cleaner fish may sometimes cheat and consume mucus or tissue, thus creating a form of parasitism. A wide variety of fish including wrasse, cichlids, catfish, pipefish, and gobies display cleaning behaviors. Similar behavior is found in other groups of animals, such as cleaner shrimps., Pipefishes or pipe-fishes (Syngnathinae) are a subfamily of small fishes, which, together with the seahorses and seadragons, form the family Syngnathidae., The wrasses are a family, Labridae, of marine fish, many of which are brightly colored. The family is large and diverse, with over 600 species in 82 genera, which are divided into 9 subgroups or tribes.
They are typically small fish, most of them less than long, although the largest, the humphead wrasse, can measure up to . They are efficient carnivores, feeding on a wide range of small invertebrates. Many smaller wrasses follow the feeding trails of larger fish, picking up invertebrates disturbed by their passing. Juveniles of some representatives of the genera "Bodianus", "Epibulus","Cirrhilabrus", "Oxycheilinus", and "Paracheilinus" hide among the tentacles of the free-living mushroom coral "Heliofungia actiniformis"., In biology/ecology, parasitism is a non-mutual relationship between species, where one species, the parasite, benefits at the expense of the other, the host. Traditionally "parasite" (in biological usage) referred primarily to organisms visible to the naked eye, or macroparasites (such as helminths). Parasites can be microparasites, which are typically smaller, such as protozoa, viruses, and bacteria. Examples of parasites include the plants mistletoe and cuscuta, and animals such as hookworms., A fish is any member of a group of organisms that consist of all gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well. However, traditionally fish are rendered obsolete or paraphyletic by excluding the tetrapods (i.e., the amphibians, reptiles, birds and mammals which all descended from within the same ancestry). Because in this manner the term "fish" is defined negatively as a paraphyletic group, it is not considered a formal taxonomic grouping in systematic biology. The traditional term pisces (also ichthyes) is considered a typological, but not a phylogenetic classification., Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia and the Piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, "Vandellia cirrhosa". There are armour-plated types and there are also naked types, neither having scales. Despite their name, not all catfish have prominent barbel. Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus "Corydoras", are important in the aquarium hobby. Many catfish are nocturnal, but others (many "Auchenipteridae") are "crepuscular" or "diurnal" (most "Loricariidae or" "Callichthyidae" for example)., Subject: labroides, Relation: parent_taxon, Options: (A) animal (B) areas (C) cichlidae (D) corydoras (E) cuscuta (F) embiotocidae (G) hagfish (H) hippolytidae (I) homo (J) labridae (K) labroidei (L) lysmata (M) olfactores (N) palaemonidae (O) perciformes (P) pipefish (Q) plant (R) pomacentridae (S) protozoa (T) siluriformes (U) stenopodidae (V) stenopus (W) syngnathidae (X) vandellia

Q: Context: In computer science, a memory leak is a type of resource leak that occurs when a computer program incorrectly manages memory allocations in such a way that memory which is no longer needed is not released. In object-oriented programming, a memory leak may happen when an object is stored in memory but cannot be accessed by the running code. A memory leak has symptoms similar to a number of other problems and generally can only be diagnosed by a programmer with access to the program's source code., In computing, source code is any collection of computer instructions, possibly with comments, written using a human-readable programming language, usually as ordinary text. The source code of a program is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source code. The source code is often transformed by an assembler or compiler into binary machine code understood by the computer. The machine code might then be stored for execution at a later time. Alternatively, source code may be interpreted and thus immediately executed., Free software, freedom-respecting software, or software libre is computer software distributed under terms that allow the software users to run the software for any purpose as well as to study, change, and distribute the software and any adapted versions. Free software is a matter of liberty, not price: users, individually or collectively, are free to do what they want with it, including the freedom to redistribute the software free of charge, or to sell it, or charge for related services such as support or warranty for profit., A computer program is a collection of instructions that performs a specific task when executed by a computer. A computer requires programs to function, and typically executes the program's instructions in a central processing unit., Object code, or sometimes an object module, is what a computer compiler produces. In a general sense object code is a sequence of statements or instructions in a computer language, usually a machine code language (i.e., binary) or an intermediate language such as Register transfer language., The River Cam is the main river flowing through Cambridge in eastern England. After leaving Cambridge, it flows north and east into the Great Ouse to the south of Ely at Pope's Corner. The Great Ouse connects the Cam to the North Sea at King's Lynn: The total distance from Cambridge to the sea is about and is navigable for punts, small boats, and rowing craft. The Great Ouse also connects to England's canal system via the Middle Level Navigations and the River Nene. In total, the Cam runs for around from its furthest source (near Debden in Essex) to its confluence with the Great Ouse. , A compiler is a computer program (or a set of programs) that transforms source code written in a programming language (the source language) into another computer language (the target language), with the latter often having a binary form known as object code. The most common reason for converting source code is to create an executable program., Valgrind is a programming tool for memory debugging, memory leak detection, and profiling., Cambridge is a university city and the county town of Cambridgeshire, England, on the River Cam about north of London. At the United Kingdom Census 2011, its population was 123,867, including 24,488 students., A census of the population of the United Kingdom is taken every ten years. The 2011 census was held in all countries of the UK on 27 March 2011. It was the first UK census which could be completed online via the Internet. The Office for National Statistics (ONS) is responsible for the census in England and Wales, the General Register Office for Scotland (GROS) is responsible for the census in Scotland, and the Northern Ireland Statistics and Research Agency (NISRA) is responsible for the census in Northern Ireland., A programming language is a formal computer language designed to communicate instructions to a machine, particularly a computer. Programming languages can be used to create programs to control the behavior of a machine or to express algorithms., A programming tool or software development tool is a computer program that software developers use to create, debug, maintain, or otherwise support other programs and applications. The term usually refers to relatively simple programs, that can be combined together to accomplish a task, much as one might use multiple hand tools to fix a physical object. The ability to use a variety of tools productively is one hallmark of a skilled software engineer., bzip2 is a free and open-source file compression program that uses the BurrowsWheeler algorithm. It only compresses single files and is not a file archiver. It is developed and maintained by Julian Seward. Seward made the first public release of bzip2, version 0.15, in July 1996. The compressor's stability and popularity grew over the next several years, and Seward released version 1.0 in late 2000., Julian Seward is a compiler writer and Free Software contributor who lives in Cambridge , UK . He is commonly known for creating the bzip2 compression tool , as well as the valgrind memory debugging toolset founded in 2000 . In 2006 , he won a second Google - O'Reilly Open Source Award for his work on Valgrind . Julian currently works at Mozilla ., A file archiver is a computer program that combines a number of files together into one archive file, or a series of archive files, for easier transportation or storage. File archivers may employ lossless data compression in their archive formats to reduce the size of the archive., Subject: julian seward, Relation: occupation, Options: (A) compiler (B) computer (C) engineer (D) king (E) programming (F) science (G) united kingdom (H) writer
