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

[Q]: Context: A sovereign state is, in international law, a nonphysical juridical entity that is represented by one centralised government that has sovereignty over a geographic area. International law defines sovereign states as having a permanent population, defined territory, one government, and the capacity to enter into relations with other sovereign states. It is also normally understood that a sovereign state is neither dependent on nor subjected to any other power or state., Slavonski Brod is a city in eastern Croatia, with a population of 59,000 in 2011. Located in the region of Slavonia, it is the centre of Brod-Posavina County and a river port on the Sava river., Croatia, officially the Republic of Croatia, is a sovereign state between Central Europe, Southeast Europe, and the Mediterranean. Its capital city is Zagreb, which forms one of the country's primary subdivisions, along with its twenty counties. Croatia covers and has diverse, mostly continental and Mediterranean climates. Croatia's Adriatic Sea coast contains more than a thousand islands. The country's population is 4.28 million, most of whom are Croats, with the most common religious denomination being Roman Catholicism., Bosnia and Herzegovina (or ; B&H; Bosnian, Croatian, Serbian: "Bosna i Hercegovina" / a   ), sometimes called Bosnia-Herzegovina (BiH), and, in short, often known informally as Bosnia, is a country in Southeastern Europe located on the Balkan Peninsula. Sarajevo is the capital and largest city. Bordered by Croatia to the north, west, and south; Serbia to the east; Montenegro to the southeast; and the Adriatic Sea to the south, with a coastline about long surrounding the city of Neum. In the central and eastern interior of the country the geography is mountainous, in the northwest it is moderately hilly, and the northeast is predominantly flatland. The inland is a geographically larger region and has a moderate continental climate, with hot summers and cold and snowy winters. The southern tip of the country has a Mediterranean climate and plain topography., The Adriatic Sea is a body of water separating the Italian Peninsula from the Balkan peninsula and the Apennine Mountains from the Dinaric Alps and adjacent ranges. The Adriatic is the northernmost arm of the Mediterranean Sea, extending from the Strait of Otranto (where it connects to the Ionian Sea) to the northwest and the Po Valley. The countries with coasts on the Adriatic are Albania, Bosnia and Herzegovina, Croatia, Greece, Italy, Montenegro and Slovenia. The Adriatic contains over 1,300 islands, mostly located along its eastern, Croatian, coast. It is divided into three basins, the northern being the shallowest and the southern being the deepest, with a maximum depth of . The Otranto Sill, an underwater ridge, is located at the border between the Adriatic and Ionian Seas. The prevailing currents flow counterclockwise from the Strait of Otranto, along the eastern coast and back to the strait along the western (Italian) coast. Tidal movements in the Adriatic are slight, although larger amplitudes are known to occur occasionally. The Adriatic's salinity is lower than the Mediterranean's because the Adriatic collects a third of the fresh water flowing into the Mediterranean, acting as a dilution basin. The surface water temperatures generally range from in summer to in winter, significantly moderating the Adriatic Basin's climate., A city is a large and permanent human settlement. Although there is no agreement on how a city is distinguished from a town in general English language meanings, many cities have a particular administrative, legal, or historical status based on local law., Slavonia is, with Dalmatia, Croatia proper, and Istria, one of the four historical regions of Croatia. Taking up the east of the country, it roughly corresponds with five Croatian counties: Brod-Posavina, Osijek-Baranja, Požega-Slavonia, Virovitica-Podravina and Vukovar-Srijem, although the territory of the counties includes Baranya, and the definition of the western extent of Slavonia as a region varies. The counties cover or 22.2% of Croatia, inhabited by 806,19218.8% of Croatia's population. The largest city in the region is Osijek, followed by Slavonski Brod and Vinkovci. It is located in the Pannonian Basin, largely bordered by the Danube, Drava and Sava rivers. In the west, the region consists of the Sava and Drava valleys, and the mountains surrounding the Požega Valley, and plains in the east. Slavonia enjoys a moderate continental climate, with relatively low precipitation., Brod - Posavina County ( Croatian : Brodsko - posavska županija ) is the southern Slavonian county in Croatia . Its center is the city of Slavonski Brod and it spreads along the left bank of the Sava river , hence the name Posavina . Other notable towns include Nova Gradiška ., Croats are a nation and South Slavic ethnic group at the crossroads of Central Europe, Southeast Europe, and the Mediterranean Sea. Croats mainly live in Croatia and Bosnia and Herzegovina, but are an officially recognized minority in Austria, Czech Republic, Hungary, Italy, Montenegro, Romania, Serbia, and Slovakia. Responding to political, social and economic pressure, many Croats have migrated throughout Europe (especially Germany, Austria, Switzerland, France and Italy) and the Americas (particularly the United States, Canada, Argentina, and Chile), establishing a diaspora., A mediterranean climate or dry summer climate is the climate typical of the lands in the Mediterranean Basin. The lands around the Mediterranean Sea form the largest area where this climate type is found, but it also is found in most of coastal California, in parts of Western and South Australia, in southwestern South Africa, sections of Central Asia, and in central Chile., Zagreb is the capital and the largest city of Croatia. It is located in the northwest of the country, along the Sava river, at the southern slopes of the Medvednica mountain. Zagreb lies at an elevation of approximately above sea level. In the last official census of 2011 the population of the City of Zagreb was 792,875. The wider Zagreb metropolitan area includes the City of Zagreb and the separate Zagreb County bringing the total metropolitan area population up to 1,237,887. It is the biggest metropolitan area in Croatia, and the only one with a population of over one million., Nova Gradiška is a city located in the Brod-Posavina County of Croatia, population 14,229 (2011). It is located in the historic region of Slavonia, near the border to Bosnia and Herzegovina., The Sava is a river in Central Europe, a right side tributary of the Danube. It flows through Slovenia, Croatia, along the northern border of Bosnia and Herzegovina, through Serbia, discharging into the Danube in Belgrade.
