Context: The Ginglymostomatidae are a cosmopolitan family of carpet sharks , containing two monotypic genera of nurse sharks . Common in shallow , tropical and subtropical waters , these sharks are sluggish and docile bottom - dwellers . Nurse sharks typically attack humans only if directly threatened . The name nurse shark is thought to be a corruption of nusse , a name which once referred to the catsharks of the family Scyliorhinidae . The nurse shark family name , Ginglymostomatidae , derives from the Greek words ginglymos ( ) meaning '' hinge '' and stoma ( ) meaning '' mouth '' ., In cryptography, SHARK is a block cipher identified as one of the predecessors of Rijndael (the Advanced Encryption Standard)., The nurse shark ("Ginglymostoma cirratum") is a shark in the family Ginglymostomatidae. Nurse sharks can reach a length of , and are native to warmer parts of the Atlantic and East Pacific., Carpet sharks are sharks classified in the order Orectolobiformes. Sometimes the common name "carpet shark" (named so because many species resemble ornately patterned carpets) is used interchangeably with "wobbegong", which is the common name of sharks in the family Orectolobidae. Carpet sharks have five gill slits, two spineless dorsal fins, and a small mouth that does not extend past the eyes. Many species have barbels., Subject: ginglymostomatidae, Relation: parent_taxon, Options: (A) ginglymostomatidae (B) orectolobiformes (C) shark

Ex Output:
orectolobiformes

Context: 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., Maritime Southeast Asia is the maritime region of Southeast Asia as opposed to mainland Southeast Asia and comprises Malaysia, Brunei, the Philippines, Singapore and Indonesia. Maritime Southeast Asia is sometimes also referred to as "island Southeast Asia" or "insular Southeast Asia". The 19th-century term "Malay Archipelago" refers to a largely similar area. , 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., Indonesia (or ; Indonesian: ), officially the Republic of Indonesia, is a unitary sovereign state and transcontinental country located mainly in Southeast Asia with some territories in Oceania. Situated between the Indian and Pacific oceans, it is the world's largest island country, with more than seventeen thousand islands. At , Indonesia is the world's 14th-largest country in terms of land area and world's 7th-largest country in terms of combined sea and land area. It has an estimated population of over 260 million people and is the world's fourth most populous country, the most populous Austronesian nation, as well as the most populous Muslim-majority country. The world's most populous island of Java contains more than half of the country's population., Borneo is the third-largest island in the world and the largest island in Asia. At the geographic centre of Maritime Southeast Asia, in relation to major Indonesian islands, it is located north of Java, west of Sulawesi, and east of Sumatra., 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., 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., The true frogs, family Ranidae, have the widest distribution of any frog family. They are abundant throughout most of the world, occurring on all continents except Antarctica. The true frogs are present in North America, northern South America, Europe, Asia, Madagascar, Africa, and from the East Indies to New Guinea; the species native to Australiathe Australian wood frog ("Hylarana daemelii")is restricted to the far north., Meristogenys is a genus of true frogs from Borneo . Its tadpoles are easily recognizable by their divided upper lip with ribs on the outside . Its closest living relative is apparently the Hole - in - the - head frog ( Huia cavitympanum ) , type species of the highly polyphyletic '' wastebin genus '' Huia . Meristogenys , having been proposed far more recently than Huia , might be included in the latter on grounds of phylogeny , as most if not all species placed in the Huia seem to belong elsewhere . But a group of species traditionally placed in Huia as well as the genus Clinotarsus are very close relatives , and therefore a taxonomic revision of this group is probably better deferred until the relationships of all taxa involved have been properly assessed ., Subject: meristogenys, Relation: parent_taxon, Options: (A) animal (B) area (C) homo (D) ranidae

Ex Output:
ranidae

Context: Between 1991 and 2006, the station was the dividing point of electrification systems (south of the station, including the station, was 1500V DC and north was 20,000V AC) so that all regional trains from Osaka and Kyoto using DC-only electric multiple units terminated at this station. In 2006 the DC zone was extended to Tsuruga Station, but there still exist some terminating trains at Nagahama., The Japan Railways Group, more commonly known as , consists of seven for-profit companies that took over most of the assets and operations of the government-owned Japanese National Railways on April 1, 1987. Most of the liability of the JNR was assumed by the JNR Settlement Corporation., The , or Kobe earthquake, occurred on January 17, 1995 at 05:46:53 JST (January 16 at 20:46:53 UTC) in the southern part of Hygo Prefecture, Japan, known as Hanshin. It measured 6.9 on the moment magnitude scale and 7 on the JMA Shindo intensity scale. The tremors lasted for approximately 20 seconds. The focus of the earthquake was located 17km beneath its epicenter, on the northern end of Awaji Island, 20km away from the city of Kobe., Beneath a square in front of the JR station is Hokutetsu-Kanazawa Station, the terminal of the Hokuriku Railroad Asanogawa Line., The is a commuter rail line in the Osaka-Kobe-Kyoto Metropolitan Area owned and operated by West Japan Railway Company (JR West). The name applies to the section of the Tkaid Main Line between Kyoto Station and Osaka Station., The is a network of high-speed railway lines in Japan operated by five Japan Railways Group companies. Starting with the Tkaid Shinkansen in 1964, the network has expanded to currently consist of of lines with maximum speeds of , of Mini-shinkansen lines with a maximum speed of , and of spur lines with Shinkansen services. The network presently links most major cities on the islands of Honshu and Kyushu, and Hakodate on northern island of Hokkaido, with an extension to Sapporo under construction and scheduled to commence in March 2031. The nickname bullet train is sometimes used in English for these high-speed trains., The is located in the northwestern part of Honshu, the main island of Japan. It lies along the Sea of Japan within the Chbu region. It is almost equivalent to Koshi Province and Hokurikud area in pre-modern Japan., The is a 176.6 kilometer railway line owned by West Japan Railway Company (JR West) connecting Maibara Station in Maibara, Shiga, with Kanazawa Station in Kanazawa, Ishikawa. It serves the Hokuriku region on the northern central coast of Honshu, the largest island of Japan, as well as offering connections to the regions of Kansai, Tkai, Kant, and Thoku., An electric multiple unit or EMU is a multiple unit train consisting of self-propelled carriages, using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. Most EMUs are used for passenger trains, but some have been built or converted for specialised non-passenger roles, such as carrying mail or luggage, or in departmental use, for example as de-icing trains. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs., The station opened on July 1, 1889. Since 1987, its main operator has been JR West, although JR Central administers the Shinkansen tracks., Lines.
Tsuruga Station is served by the following JR West lines., Economy.
Kita-ku, particularly the Umeda area surrounding Osaka Station, is one of the main commercial centers of Osaka. Kita-ku is also a financial administration center, housing the headquarters of the Japan Mint and the Osaka branch of the Bank of Japan., The is the nickname of portions of the Tokaido Main Line and the Sanyo Main Line, between Osaka Station in Osaka, Osaka Prefecture and Himeji Station in Himeji, Hygo Prefecture. The line, along with the JR Kyoto Line and the Biwako Line, forms a contiguous service that is the main trunk of West Japan Railway Company's Urban Network commuter rail network in the Osaka-Kobe-Kyoto Metropolitan Area. The line also offers continuous service to the Gakkentoshi Line via the JR Tzai Line. It was damaged during the 1995 Great Hanshin earthquake., , also referred to as , is one of the Japan Railways Group (JR Group) companies and operates in western Honshu. It has its headquarters in Kita-ku, Osaka., The is a major Japanese railway line of the Japan Railways Group (JR Group) network, connecting and Kbe stations. It is long, not counting its many freight feeder lines around the major cities. The high-speed Tokaido Shinkansen largely parallels the line., As of August 1, 2006, the city has an estimated population of 40,349 and a population density of 161 persons per km. The total area is 250.46km.,
Operation.
All trains make local stop at every station on the line. Some trains terminate at Amagasaki, but most westbound trains continue on the Kobe Line to Nishi-Akashi and on the Takarazuka Line to Tsukaguchi and Takarazuka. All eastbound trains continue past Kyobashi on the Gakkentoshi Line., Honshu had a population of 103 million , mostly concentrated in the coastal lowlands, notably in the Kant plain where 25% of the total population resides in the Greater Tokyo Area. As the historical center of Japanese culture and political power, the island includes several past Japanese capitals, including Kyoto, Nara, and Kamakura. Much of the island's southern shore forms part of the Taiheiy Belt, a megalopolis that spans several of the Japanese islands., The Biwako Line ( Biwako - sen ) is the nickname used by the operator of the West Japan Railway Company ( JR West ) to refer to the portion of the Tkaid Main Line ( between Maibara Station and Kyoto Station ) and the Hokuriku Main Line ( between Maibara Station and Nagahama Station ) . The section , along with JR Kyoto Line and JR Kobe Line , forms a contiguous service that is the main trunk of JR West 's '' Urban Network '' commuter rail network in the Osaka - Kobe - Kyoto Metropolitan Area ., Historically a merchant city, Osaka has also been known as the and served as a center for the rice trade during the Edo period., The station building is located close to the Sanyo Electric Railway Himeji Station and Himeji Castle., History.
Present-day Hygo Prefecture includes the former provinces of Harima, Tajima, Awaji, and parts of Tanba and Settsu., Commuter rail, also called suburban rail, is a passenger rail transport service that primarily operates between a city centre, and the middle to outer suburbs beyond 15km (10 miles) and commuter towns or other locations that draw large numbers of commuterspeople who travel on a daily basis. Trains operate following a schedule, at speeds varying from 50 to 200km/h (30 to 125mph).
