TASK DEFINITION: In this task, you are given a context, a subject, a relation, and many options. Based on the context, from the options select the object entity that has the given relation with the subject. Answer with text (not indexes).
PROBLEM: Context: In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, trivial name, trivial epithet, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; this kind of name is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is by no means always the case., Verdigris is the common name for a green pigment obtained through the application of acetic acid to copper plates or the natural patina formed when copper, brass or bronze is weathered and exposed to air or seawater over a period of time. It is usually a basic copper carbonate, but near the sea will be a basic copper chloride. If acetic acid is present at the time of weathering, it may consist of copper(II) acetate., 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., 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., Green is the color between blue and yellow on the spectrum of visible light. It is evoked by light with a predominant wavelength of roughly 495570 nm. In the subtractive color system, used in painting and color printing, it is created by a combination of yellow and blue, or yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors.
The modern English word green comes from the Middle English and Anglo-Saxon word "grene", from the same Germanic root as the words "grass" and "grow". It is the color of living grass and leaves and as a result is the color most associated with springtime, growth and nature. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content.
In surveys made in Europe and the United States, green is the color most commonly associated with nature, life, health, youth, spring, hope and envy. In Europe and the U.S. green is sometimes associated with death (green has several seemingly contrary associations), sickness, or the devil, but in China its associations are very positive, as the symbol of fertility and happiness. In the Middle Ages and Renaissance, when the color of clothing showed the owner's social status, green was worn by merchants, bankers and the gentry, while red was the color of the nobility. The "Mona Lisa" by Leonardo da Vinci wears green, showing she is not from a noble family; the benches in the British House of Commons are green, while those in the House of Lords are red. Green is also the traditional color of safety and permission; a green light means go ahead, a green card permits permanent residence in the United States. It is the most important color in Islam. It was the color of the banner of Muhammad, and is found in the flags of nearly all Islamic countries, and represents the lush vegetation of Paradise. It is also often associated with the culture of Gaelic Ireland, and is a color of the flag of Ireland. Because of its association with nature, it is the color of the environmental movement. Political groups advocating environmental protection and social justice describe themselves as part of the Green movement, some naming themselves Green parties. This has led to similar campaigns in advertising, as companies have sold green, or environmentally friendly, products., The genus Stropharia ( sometimes known by the common name roundheads ) is a group of medium to large agarics with a distinct membranous ring on the stipe . Well - known members of this genus include the edible Stropharia rugosoannulata and the blue - green verdigris agarics ( Stropharia aeruginosa and allies ) . Stropharia are not generally regarded as good to eat and there are doubts over the edibility of several species . However the species Stropharia rugosoannulata is regarded as exquisitely edible when young , is now the premier mushroom for outdoor bed culture by mycophiles in temperate climates ., Stropharia rugosoannulata, commonly known as the wine cap stropharia, "garden giant", burgundy mushroom or king stropharia (Japanese: "saketsubatake"), is an agaric of the family Strophariaceae found in Europe and North America, and introduced to Australia and New Zealand., 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., Woodland is a low-density forest forming open habitats with plenty of sunlight and limited shade. Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are referred to as forests. , An agaric or is a type of mushroom fungus fruiting body characterized by the presence of a pileus (cap) that is clearly differentiated from the stipe (stalk), with lamellae (gills) on the underside of the pileus. "Agaric" can also refer to a basidiomycete species characterized by an agaric-type fruiting body. Archaically agaric meant 'tree-fungus' (after Latin "agaricum"); however, that changed with the Linnaean interpretation in 1753 when Linnaeus used the generic name "Agaricus" for gilled mushrooms., Stropharia aeruginosa, commonly known as the verdigris agaric, is a medium-sized green, slimy woodland mushroom, found on lawns, mulch and woodland from spring to autumn. The edibility of this mushroom is controversial - some sources claim that it is edible, while others claim it to be poisonous, although effects are little known and its toxic constituents undescribed., The Strophariaceae are a family of fungi in the order Agaricales. Under an older classification, the family covered 18 genera and 1316 species. The species of Strophariaceae have red-brown to dark brown spore prints, while the spores themselves are smooth and have an apical germ pore. These agarics are also characterized by having a cutis-type pileipellis. Ecologically, all species in this group are saprotrophs, growing on various kinds of decaying organic matter. The family was circumscribed in 1946 by mycologists Rolf Singer and Alexander H. Smith., Subject: stropharia, Relation: parent_taxon, Options: (A) agaricus (B) animal (C) area (D) areas (E) leonardo (F) plant (G) stropharia (H) strophariaceae

SOLUTION: strophariaceae

PROBLEM: Context: Eugene Hugh Beaumont (February 16, 1909  May 14, 1982) was an American actor and television director. He was also licensed to preach by the Methodist church. Beaumont is best known for his portrayal of Ward Cleaver on the television series "Leave It to Beaver", originally broadcast from 1957 to 1963. He also sold Christmas trees and would rush home to his farm in Minnesota when production ended. This is why a different voice playing Ward narrated some episodes. He had earlier played the role of the private detective Michael Shayne in a series of films in the 1940s., Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency. For example, if a newborn baby's heart beats at a frequency of 120 times a minute, its periodthe time interval between beatsis half a second (that is, 60 seconds divided by 120 beats). Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio (sound) signals, radio waves, and light., Oral tradition, or oral lore, is a form of human communication wherein knowledge, art, ideas and cultural material is received, preserved and transmitted orally from one generation to another. The transmission is through speech or song and may include folktales, ballads, chants, prose or verses. In this way, it is possible for a society to transmit oral history, oral literature, oral law and other knowledge across generations without a writing system, or in parallel to a writing system. Indian religions such as Buddhism, Hinduism and Jainism, for example, have used an oral tradition, in parallel to a writing system, to transmit their canonical scriptures, secular knowledge such as Sushruta Samhita, hymns and mythologies from one generation to the next., Day the World Ended is a 1955 post-apocalyptic science fiction film directed by Roger Corman. The story centers on a heroic scientist who, among others, must face off against a mutant monster after an atomic war destroys human civilization. Chet Huntley of NBC, later of "The Huntley-Brinkley Report", served as narrator. The film was released by American International Pictures as a double feature with "The Phantom from 10,000 Leagues"., NeWS (Network extensible Window System) is a discontinued windowing system developed by Sun Microsystems in the mid-1980s. Originally known as "SunDew", its primary authors were James Gosling and David S. H. Rosenthal. The NeWS interpreter was based on PostScript (as was the later Display PostScript, although the two projects were otherwise unrelated) extending it to allow interaction and multiple "contexts" to support windows. Like PostScript, NeWS could be used as a complete programming language, but unlike PostScript, NeWS could be used to make complete interactive programs with mouse support and a GUI., Leave It to Beaver is an American television sitcom about an inquisitive and often naïve boy, Theodore "The Beaver" Cleaver (portrayed by Jerry Mathers), and his adventures at home, in school, and around his suburban neighborhood. The show also starred Barbara Billingsley and Hugh Beaumont as Beaver's parents, June and Ward Cleaver, and Tony Dow as Beaver's brother Wally. The show has attained an iconic status in the United States, with the Cleavers exemplifying the idealized suburban family of the mid-20th century., A B movie is a low-budget commercial movie that is not an arthouse film. In its original usage, during the Golden Age of Hollywood, the term more precisely identified a film intended for distribution as the less-publicized, bottom half of a double feature. Although the U.S. production of movies intended as second features largely ceased by the end of the 1950s, the term "B movie" continued to be used in the broader sense it maintains today. In its postGolden Age usage, there is ambiguity on both sides of the definition: on the one hand, the primary interest of many inexpensive exploitation films is prurient; on the other, many B movies display a high degree of craft and aesthetic ingenuity., Brett Halliday (July 31, 1904  February 4, 1977), primary pen name of Davis Dresser, was an American mystery writer, best known for the long-lived series of "Michael Shayne" novels he wrote, and later commissioned others to write. Dresser wrote non-series mysteries, westerns and romances under the names Asa Baker, Matthew Blood, Kathryn Culver, Don Davis, Hal Debrett, Anthony Scott, Peter Field, and Anderson Wayne., The Big Three television networks are the three major traditional commercial broadcast television networks in the United States: ABC, CBS and NBC. Beginning in 1948 until the late 1980s, the Big Three networks dominated U.S. television., Advertising is an audio or visual form of marketing communication that employs an openly sponsored, nonpersonal message to promote or sell a product, service or idea. Sponsors of advertising are often businesses who wish to promote their products or services. Advertising is differentiated from public relations in that an advertiser usually pays for and has control over the message. It is differentiated from personal selling in that the message is nonpersonal, i.e., not directed to a particular individual.
Advertising is communicated through various mass media, including old media such as newspapers, magazines, Television, Radio, outdoor advertising or direct mail; or new media such as search results, blogs, websites or text messages. The actual presentation of the message in a medium is referred to as an advertisement or "ad"., Comcast Corporation (formerly registered as Comcast Holdings) is an American global telecommunications conglomerate that is the largest broadcasting and cable television company in the world by revenue. It is the second-largest pay-TV company after the AT&T-DirecTV acquisition, largest cable TV company and largest home Internet service provider in the United States, and the nation's third-largest home telephone service provider. Comcast services U.S. residential and commercial customers in 40 states and in the District of Columbia. The company's headquarters are located in Philadelphia, Pennsylvania. As the owner of the international media company NBCUniversal since 2011, Comcast is a producer of feature films and television programs intended for theatrical exhibition and over-the-air and cable television broadcast., Monochrome describes paintings, drawings, design, or photographs in one color or values of one color. A monochromatic object or image reflects colors in shades of limited colors or hues. Images using only shades of grey (with or without black or white) are called grayscale or black-and-white. However, scientifically speaking, monochromatic light refers to visible light of a narrow band of wavelengths (see spectral color)., Science fiction (often shortened to SF, sci-fi or scifi) is a genre of speculative fiction, typically dealing with imaginative concepts such as futuristic science and technology, space travel, time travel, faster than light travel, parallel universes, and extraterrestrial life. Science fiction often explores the potential consequences of scientific and other innovations, and has been called a "literature of ideas." It usually avoids the supernatural, and unlike the related genre of fantasy, historically science fiction stories were intended to have a grounding in science-based fact or theory at the time the story was created, but this connection is now limited to hard science fiction., Chicago (or ), officially the City of Chicago, is the third-most populous city in the United States, and the fifth-most populous city in North America. With over 2.7 million residents, it is the most populous city in the state of Illinois and the Midwestern United States, and the county seat of Cook County. The Chicago metropolitan area, often referred to as Chicagoland, has nearly 10 million people and is the third-largest in the U.S., Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies as high as 300 GHz to as low as 3 kHz, though some definitions describe waves above 1 or 3 GHz as microwaves, or include waves of any lower frequency. At 300 GHz, the corresponding wavelength is , and at 3 kHz is . Like all other electromagnetic waves, they travel at the speed of light. Naturally occurring radio waves are generated by lightning, or by astronomical objects. , Cary Grant (born Archibald Alexander Leach; January 18, 1904  November 29, 1986) was a British-American actor, known as one of classic Hollywood's definitive leading men. He began a career in Hollywood in the early 1930s, and became known for his transatlantic accent, debonair demeanor, and light-hearted approach to acting and sense of comic timing. He became an American citizen in 1942., The National Broadcasting Company (NBC) is an American commercial broadcast television network that is the flagship property of NBCUniversal, a subsidiary of Comcast. The network is headquartered in the Comcast Building (formerly known as the GE Building) at Rockefeller Center in New York City, with additional major offices near Los Angeles (at Universal City Plaza), Chicago (at the NBC Tower) and soon in Philadelphia at Comcast Innovation and Technology Center. The network is part of the Big Three television networks. NBC is sometimes referred to as the "Peacock Network", in reference to its stylized peacock logo, which was originally created in 1956 for its then-new color broadcasts and became the network's official emblem in 1979., A detective is an investigator, usually a member of a law enforcement agency. Some are private persons, and may be known as private investigators, as "The Eye That Never Sleeps", the motto of the Pinkerton Detective Agency or shortened to simply "private eyes"., A television network is a telecommunications network for distribution of television program content, whereby a central operation provides programming to many television stations or pay television providers. Until the mid-1980s, television programming in most countries of the world was dominated by a small number of broadcast networks. Many early television networks (such as the BBC, NBC or CBC) evolved from earlier radio networks., A television director directs the activities involved in making a television program and is part of a television crew., Richard Denning (March 27, 1914  October 11, 1998) was an American actor best known for starring in science fiction films of the 1950s, including "Unknown Island" (1948), "Creature from the Black Lagoon" (1954), "Target Earth" (1954), "Day the World Ended" (1955), "Creature with the Atom Brain" (1955), and "The Black Scorpion" (1957). Denning also appeared in the film "An Affair to Remember" (1957) with Cary Grant and on radio with Lucille Ball, as George and Liz Cooper, in "My Favorite Husband" (19481951), the forerunner of television's "I Love Lucy"., Lloyd Benedict Nolan (August 11, 1902  September 27, 1985) was an American film and television actor. Among his many roles, Nolan is remembered for originating the roles of private investigator Michael Shayne in a series of 1940s B Movies. , Entertainment is a form of activity that holds the attention and interest of an audience, or gives pleasure and delight. It can be an idea or a task, but is more likely to be one of the activities or events that have developed over thousands of years specifically for the purpose of keeping an audience's attention. Although people's attention is held by different things, because individuals have different preferences in entertainment, most forms are recognisable and familiar. Storytelling, music, drama, dance, and different kinds of performance exist in all cultures, were supported in royal courts, developed into sophisticated forms and over time became available to all citizens. The process has been accelerated in modern times by an entertainment industry that records and sells entertainment products. Entertainment evolves and can be adapted to suit any scale, ranging from an individual who chooses a private entertainment from a now enormous array of pre-recorded products; to a banquet adapted for two; to any size or type of party, with appropriate music and dance; to performances intended for thousands; and even for a global audience., Rockefeller Center is a large complex consisting of 19 highrise commercial buildings covering between 48th and 51st Streets in New York City. Commissioned by the Rockefeller family, it is located in the center of Midtown Manhattan, spanning the area between Fifth Avenue and Sixth Avenue. It was declared a National Historic Landmark in 1987., A television set, more commonly called a television, TV, TV set, television receiver, or telly, is a device that combines a tuner, display, and loudspeakers for the purpose of viewing television. Introduced in the late 1920s in mechanical form, television sets became a popular consumer product after World War II in electronic form, using cathode ray tubes. The addition of color to broadcast television after 1953 further increased the popularity of television sets in the 1960s, and an outdoor antenna became a common feature of suburban homes. The ubiquitous television set became the display device for the first recorded media in the 1970s, such as Betamax, VHS and later DVD. It was also the display device for the first generation of home computers (e.g., Timex Sinclair 1000) and video game consoles (e.g., Atari) in the 1980s. In the 2010s flat panel television incorporating liquid-crystal displays, especially LED-backlit LCDs, largely replaced cathode ray tubes and other displays., I Love Lucy is a landmark American television sitcom starring Lucille Ball, Desi Arnaz, Vivian Vance, and William Frawley. The black-and-white series originally ran from October 15, 1951, to May 6, 1957, on CBS. After the series ended in 1957, however, a modified version continued for three more seasons with 13 one-hour specials; it ran from 1957 to 1960. It was first known as "The Lucille Ball-Desi Arnaz Show" and later in reruns as "The LucyDesi Comedy Hour"., The NBC Tower is an office tower on the Near North Side of Chicago, Illinois, United States located at 454 North Columbus Drive (455 North Cityfront Plaza is also used as a vanity address for the building) in downtown Chicago's Magnificent Mile area. Completed in 1989, the 37-story building reaches a height of 627 feet (191 m). NBC's Chicago offices, studios, and owned-and-operated station WMAQ-TV are located here as of 1989 and on October 1, 1989, WMAQ-TV broadcast their first newscast at 10 pm that evening at their new home, NBC Tower with the then-weeknight news team of Ron Magers, Carol Marin, John Coleman and Mark Giangreco. Later, Telemundo O&O WSNS-TV since their 2002 purchase by NBC. Formerly its former radio sister WMAQ/WSCR was located here. NBC's former Chicago FM property, WKQX and its sister station WLUP will move their studios to the NBC Tower in the summer of 2016., Lucille Désirée Ball (August 6, 1911  April 26, 1989) was an American actress, comedian, model, film-studio executive, and producer. She was best known as the star of the self-produced sitcoms "I Love Lucy", "The LucyDesi Comedy Hour", "The Lucy Show", "Here's Lucy", and "Life with Lucy"., Ward Cleaver, Jr. is a fictional character in the American television sitcom "Leave It to Beaver". Ward and his wife, June, are often invoked as archetypal suburban parents of the babyboomer 1950s. The couple are the parents of Wally, a thirteen-year-old in the eighth grade, and seven-year-old ("almost eight") second-grader Theodore, nicknamed "The Beaver". A typical episode from "Leave It to Beaver" follows a misadventure committed by one or both of the boys, and ends with the culprits receiving a moral lecture from their father and a hot meal from their mother., In physics and electrical engineering, a conductor is an object or type of material that allows the flow of an electrical current in one or more directions. A metal wire is a common electrical conductor. Electrical current is generated by the flow of negatively charged electrons, positively charged holes, and positive or negative ions in some cases. , My Favorite Husband is the name of an American radio program and network television series. The original radio show, starring Lucille Ball, evolved into the groundbreaking TV sitcom "I Love Lucy". The series was based on the novels "Mr. and Mrs. Cugat, the Record of a Happy Marriage" (1940) and "Outside Eden" (1945) written by Isabel Scott Rorick, which had previously been adapted into the Paramount Pictures feature film "Are Husbands Necessary?" (1942), co-starring Ray Milland and Betty Field., Television or TV is a telecommunication medium used for transmitting moving images in monochrome (black-and-white), or in color, and in two or three dimensions and sound. It can refer to a television set, a television program ("TV show"), or the medium of television transmission. Television is a mass medium, for entertainment, education, news, and advertising., Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form., A pen name ("nom de plume", or "literary double") is a pseudonym (or, in some cases, a variant form of a real name) adopted by an author and printed on the title page or by-line of his or her works in place of their "real" name. A pen name may be used to make the author's name more distinctive, to disguise his or her gender, to distance an author from some or all of his or her previous works, to protect the author from retribution for his or her writings, to combine more than one author into a single author, or for any of a number of reasons related to the marketing or aesthetic presentation of the work. The author's name may be known only to the publisher, or may come to be common knowledge., A writer is a person who uses written words in various styles and techniques to communicate their ideas. Writers produce various forms of literary art and creative writing such as novels, short stories, poetry, plays, screenplays, and essays as well as various reports and news articles that may be of interest to the public. Writers' texts are published across a range of media. Skilled writers who are able to use language to express ideas well often contribute significantly to the cultural content of a society. The word is also used elsewhere in the arts  such as songwriter  but as a standalone term, "writer" normally refers to the creation of written language. Some writers work from an oral tradition., In physics, energy is the property that must be transferred to an object in order to perform work on  or to heat  the object, and can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the mechanical work of moving it a distance of 1 metre against a force of 1 newton., A television program is a segment of content intended for broadcast on over-the-air, cable television, or Internet television, other than a commercial, trailer, or any other segment of content not serving as attraction for viewership. It may be a single production, or more commonly, a series of related productions (also called a television series or a television show)., Michael Shayne is a fictional private detective character created during the late 1930s by writer Brett Halliday . The character appeared in a series of seven films starring Lloyd Nolan for Twentieth Century Fox , four films from the low - budget Producers Releasing Corporation with Hugh Beaumont , a radio series under a variety of titles between 1944 and 1953 , and later in 1960 -- 1961 in a 32 - episode NBC television series starring Richard Denning in the title role ., Technology ("science of craft", from Greek , "techne", "art, skill, cunning of hand"; and , "-logia") is the collection of techniques, skills, methods and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation. Technology can be the knowledge of techniques, processes, and the like, or it can be embedded in machines which can be operated without detailed knowledge of their workings., Subject: michael shayne, Relation: occupation, Options: (A) acting (B) actor (C) actress (D) advertising (E) author (F) band (G) comedian (H) commercial (I) cook (J) detective (K) electrical engineering (L) engineering (M) entertainment (N) father (O) game (P) interpreter (Q) investigator (R) law enforcement (S) literary (T) major (U) member (V) model (W) narrator (X) physics (Y) private investigator (Z) programming ([) public relations (\) radio (]) science (^) songwriter (_) television (`) writer (a) writing system

PROBLEM: Context: Asia is Earth's largest and most populous continent, located primarily in the eastern and northern hemispheres and sharing the continental landmass of Eurasia with the continent of Europe. Asia covers an area of , about 30% of Earth's total land area and 8.7% of the Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Asia is notable for not only its overall large size and population, but also dense and large settlements as well as vast barely populated regions within the continent of 4.4 billion people., 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., The Atlantic Ocean is the second largest of the world's oceans with a total area of about . It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World"., 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., Sturgeon is the common name for the 27 species of fish belonging to the family Acipenseridae. Their evolution dates back to the Triassic some 245 to 208 million years ago. The family is grouped into four genera: "Acipenser", "Huso", "Scaphirhynchus" and "Pseudoscaphirhynchus". Four species may now be extinct. Two closely related species, "Polyodon spathula" (paddlefish) and "Psephurus gladius" (Chinese paddlefish, possibly extinct) are of the same order, Acipenseriformes, but are in the family Polyodontidae and are not considered to be "true" sturgeons. Both sturgeons and paddlefish have been referred to as "primitive fishes" because their morphological characteristics have remained relatively unchanged since the earliest fossil record. Sturgeons are native to subtropical, temperate and sub-Arctic rivers, lakes and coastlines of Eurasia and North America. 
Sturgeons are long-lived, late-maturing fishes with distinctive characteristics, such as a heterocercal caudal fin similar to that of sharks, and an elongated spindle-like body that is smooth-skinned, scaleless and armored with 5 lateral rows of bony plates called scutes. Several species can grow quite large, typically ranging 712 feet (2-3 m) in length. The largest sturgeon on record was a Beluga female captured in the Volga estuary in 1827, weighing and long. Most sturgeons are anadromous bottom-feeders which migrate upstream to spawn but spend most of their lives feeding in river deltas and estuaries. Some species inhabit freshwater environments exclusively while others primarily inhabit marine environments near coastal areas, and are known to venture into open ocean., 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., Eurasia is the combined continental landmass of Europe and Asia. The term is a portmanteau of its constituent continents. Located primarily in the Northern and Eastern Hemispheres, it is bordered by the Atlantic Ocean to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two different continents is a historical and cultural construct, with no clear physical separation between them; thus, in some parts of the world, Eurasia is recognized as the largest of five or six continents. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on the paleomagnet data., Africa is the world's second-largest and second-most-populous continent. At about 30.3 million km² (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20.4 % of its total land area. With 1.1 billion people as of 2013, it accounts for about 15% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west.
