[Q]: Context: In cryptography, a block cipher is a deterministic algorithm operating on fixed-length groups of bits, called "blocks", with an unvarying transformation that is specified by a symmetric key. Block ciphers operate as important elementary components in the design of many cryptographic protocols, and are widely used to implement encryption of bulk data., The Ecuadorian horned frog ( Ceratophrys testudo ) is a species of frog in the Ceratophryidae family . It is endemic to Ecuador . Its natural habitats are subtropical or tropical moist montane forests and intermittent freshwater marshes ., Ecuador, officially the Republic of Ecuador (which literally translates as "Republic of the Equator"), is a representative democratic republic in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean to the west. Ecuador also includes the Galápagos Islands in the Pacific, about west of the mainland., The Cretaceous is a geologic period and system that spans 79 million years from the end of the Jurassic Period million years ago (Mya) to the beginning of the Paleogene Period Mya. It is the last period of the Mesozoic Era. The Cretaceous Period is usually abbreviated K, for its German translation "Kreide" (chalk)., In cryptography, FROG is a block cipher authored by 
Georgoudis, Leroux and Chaves. The algorithm can work with any block size between 8 and 128 bytes, and supports key sizes between 5 and 125 bytes. The algorithm consists of 8 rounds and has a very complicated key schedule. , The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures.
The size of the byte has historically been hardware dependent and no definitive standards existed that mandated the size. The "de facto" standard of eight bits is a convenient power of two permitting the values 0 through 255 for one byte. The international standard IEC 80000-13 codified this common meaning. Many types of applications use information representable in eight or fewer bits and processor designers optimize for this common usage. The popularity of major commercial computing architectures has aided in the ubiquitous acceptance of the 8-bit size., In geology, a supercontinent is the assembly of most or all of Earth's continental blocks or cratons to form a single large landmass. However, the definition of a supercontinent can be ambiguous. Many earth scientists, such as P.F. Hoffman (1999), use the term "supercontinent" to mean "a clustering of nearly all continents". This definition leaves room for interpretation when labeling a continental body and is easier to apply to Precambrian times. Using the first definition provided here, Gondwana (a.k.a. Gondwanaland) is not considered a supercontinent, because the landmasses of Baltica, Laurentia and Siberia also existed at the same time but physically separate from each other. The landmass of Pangaea is the collective name describing all of these continental masses when they were in proximity to one another. This would classify Pangaea as a supercontinent. According to the definition by Rogers and Santosh (2004), a supercontinent does not exist today. Supercontinents have assembled and dispersed multiple times in the geologic past (see table). The positions of continents have been accurately determined back to the early Jurassic. However, beyond , continental positions are much less certain., The Ceratophryidae, known as common horned frogs, are a family of frogs found in South America. It is a relatively small family with three extant genera and 12 species. However, fossils of the giant "Beelzebufo" from Cretaceous Madagascar suggest the taxon may have once ranged throughout the prehistoric supercontinent of Gondwana., The Equator usually refers to an imaginary line on the Earth's surface equidistant from the North Pole and South Pole, dividing the Earth into the Northern Hemisphere and Southern Hemisphere. The Equator is about long; some 78.7% lies across water and 21.3% over land., Madagascar, officially the Republic of Madagascar, and previously known as the Malagasy Republic, is an island country in the Indian Ocean, off the coast of Southeast Africa. The nation comprises the island of Madagascar (the fourth-largest island in the world), and numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian peninsula around 88 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of its wildlife is found nowhere else on Earth. The island's diverse ecosystems and unique wildlife are threatened by the encroachment of the rapidly growing human population and other environmental threats., 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., Colombia (or ), officially the Republic of Colombia, is a transcontinental country largely situated in the northwest of South America, with territories in Central America. Colombia shares a border to the northwest with Panama, to the east with Venezuela and Brazil and to the south with Ecuador and Peru. It shares its maritime limits with Costa Rica, Nicaragua, Honduras, Jamaica, the Dominican Republic and Haiti. It is a unitary, constitutional republic comprising thirty-two departments. The territory of what is now Colombia was originally inhabited by indigenous peoples including the Muisca, the Quimbaya and the Tairona., Beelzebufo ampinga (or ) was a particularly large species of prehistoric frog described in 2008. Common names assigned by the popular media include devil frog, devil toad, and the frog from hell., Cryptography or cryptology (from Greek "kryptós", "hidden, secret"; and "graphein", "writing", or "-logia", "study", respectively) is the practice and study of techniques for secure communication in the presence of third parties called adversaries. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages; various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation are central to modern cryptography. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, and electrical engineering. Applications of cryptography include ATM cards, computer passwords, and electronic commerce., In cryptography, the so-called product ciphers are a certain kind of ciphers, where the (de-)ciphering of data is done in "rounds". The general setup of each round is the same, except for some hard-coded parameters and a part of the cipher key, called a subkey. A key schedule is an algorithm that, given the key, calculates the subkeys for these rounds., South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere. It is also considered a subcontinent of the Americas, which is the model used in nations that speak Romance languages. The reference to South America instead of other regions (like Latin America or the Southern Cone) has increased in the last decades due to changing geopolitical dynamics (in particular, the rise of Brazil)., The Galápagos Islands (official name: "Archipiélago de Colón", other Spanish name: "Islas Galápagos") are an archipelago of volcanic islands distributed on either side of the Equator in the Pacific Ocean surrounding the centre of the Western Hemisphere, west of continental Ecuador, of which they are a part. The islands are known for their vast number of endemic species and were studied by Charles Darwin during the voyage of the "Beagle", as his observations and collections contributed to the inception of Darwin's theory of evolution by natural selection., In paleogeography, Gondwana,
also Gondwanaland, is the name given to an ancient supercontinent. It is believed to have sutured between about 573 and 510 million years ago (Mya), joining East Gondwana to West Gondwana. Gondwana formed prior to Pangaea, and later became part of it., Peru , officially the Republic of Peru, is a country in western South America. It is bordered in the north by Ecuador and Colombia, in the east by Brazil, in the southeast by Bolivia, in the south by Chile, and in the west by the Pacific Ocean. Peru is an extremely biodiverse country with habitats ranging from the arid plains of the Pacific coastal region in the west to the peaks of the Andes mountains vertically extending from the north to the southeast of the country to the tropical Amazon Basin rainforest in the east with the Amazon river., Subject: ecuadorian horned frog, Relation: instance_of, Options: (A) algorithm (B) assembly (C) block cipher (D) border (E) cipher (F) coast (G) collective (H) communication (I) computer (J) constitutional republic (K) continent (L) country (M) cryptography (N) data (O) deterministic algorithm (P) eight (Q) era (R) family (S) geology (T) hotspot (U) information (V) international standard (W) key (X) landmass (Y) line (Z) mathematics ([) model (\) name (]) number (^) ocean (_) official (`) period (a) population (b) power of two (c) practice (d) processor (e) product (f) public (g) reference (h) region (i) representative (j) republic (k) river (l) single (m) size (n) species (o) study (p) subcontinent (q) supercontinent (r) table (s) taxon (t) three (u) transcontinental country (v) work (w) writing

[Q]: Context: The Lophotrochozoa ("crest/wheel animals") are a major grouping of protostome animals. The taxon was discovered based on molecular data. Molecular evidence such as a result of studies of the evolution of small-subunit ribosomal RNA (rRNA) supports the monophyly of the phyla listed in the infobox shown at right., Protostomia (from Greek - "proto-" "first" and  "stoma" "mouth") are a clade of animals. Together with the deuterostomes and xenacoelomorpha, they make up the Bilateria, mostly comprising animals with bilateral symmetry and three germ layers. The major distinctions between deuterostomes and protostomes are found in embryonic development: most (but, confusingly, not all) protostomes undergo Protostomy, whereas most deuterostomes undergo Deuterostomy., The Spiralia are a morphologically diverse clade of animals , including within their number of molluscs , annelids , platyhelminths and other phyla . The Spiralian clade of animals are more commonly referred to as the Lophotrochozoa , although whether these two terms are equivalent is debated , as noted further below . More uncontroversially , the term Spiralia is applied to those phyla that exhibit canonical spiralian cleavage . Spiral cleavage , from which this group draws its name , is a pattern of early development found in most ( but not all ) members of the Lophotrochozoa ., Subject: spiralia, Relation: parent_taxon, Options: (A) bilateria (B) lophotrochozoa (C) phyla (D) xenacoelomorpha

[Q]: Context: Seating capacity is the number of people who can be seated in a specific space, in terms of both the physical space available, and limitations set by law. Seating capacity can be used in the description of anything ranging from an automobile that seats two to a stadium that seats hundreds of thousands of people. The largest sporting venue in the world, the Indianapolis Motor Speedway, has a permanent seating capacity for more than 235,000 people and infield seating that raises capacity to an approximate 400,000., Michie Stadium / maki / is an outdoor football stadium on the campus of the U.S. Military Academy in West Point , New York . The home field for the Army Black Knights , it opened in 1924 and has a current seating capacity of 38,000 . The stadium sits at the upper portion of campus , directly west of Lusk Reservoir . The field is at an elevation of 335 feet ( 102 m ) above sea level and runs in the traditional north - south configuration , with the press box above the west sideline . Because of the view offered by its location overlooking the Hudson River and the medieval - style campus below , it was rated as Sports Illustrated 's # 3 sports venue of the 20th century ., The Indianapolis Motor Speedway, located in Speedway, Indiana, (an enclave suburb of Indianapolis) in the United States, is the home of the Indianapolis 500 and the Brickyard 400. It is located on the corner of 16th Street and Georgetown Road, approximately west of Downtown Indianapolis., Orange County is a county located in the U.S. state of New York. As of the 2010 census, the population was 372,813. The county seat is Goshen. This county was first created in 1683 and reorganized with its present boundaries in 1798., West Point is the oldest continuously occupied military post in the United States. West Point was established in 1775 by George Washington who considered it the most important strategic position in America. Until January 1778, West Point was not occupied by the military. On January 27, 1778, Brigadier General Samuel Holden Parsons and his brigade crossed the ice on the Hudson River and climbed to the plain on West Point and from that day to the present, West Point has been occupied by the United States Army. It comprises approximately including the campus of the United States Military Academy at West Point, which is also frequently called "West Point". It is a Census Designated Place (CDP) located in the Town of Highlands in Orange County, New York, located on the western bank of the Hudson River. The population was 6,763 at the 2010 census. It is part of the New York-Newark-Jersey City, NY-NJ-PA Metropolitan Statistical Area as well as the larger New York-Newark, NY-NJ-CT-PA Combined Statistical Area., The United States Military Academy (USMA), also known as West Point, Army, The Academy, or simply The Point, is a four-year coeducational federal service academy located in West Point, New York in Orange County.
