Question: Context: A university ("a whole", "a corporation") is an institution of higher (or tertiary) education and research which grants academic degrees in various subjects. 
Universities typically provide undergraduate education and postgraduate education., Virginia Polytechnic Institute and State University, popularly known as Virginia Tech, is a public, land-grant, research university with a main campus in Blacksburg, Virginia, educational facilities in six regions statewide, and a study-abroad site in Switzerland. Through its Corps of Cadets ROTC program, Virginia Tech is also designated as a one of six senior military colleges in the country. As the commonwealth's third-largest university, Virginia Tech offers 225 undergraduate and graduate degree programs to some 30,600 students and manages a research portfolio of $513 million, the largest of any university in Virginia. The university fulfills its land-grant mission of transforming knowledge to practice through technological leadership and by fueling economic growth and job creation locally, regionally, and across Virginia., Blacksburg is an incorporated town in Montgomery County, Virginia, United States, with a population of 42,620 at the 2010 census. Blacksburg is dominated economically and demographically by the presence of Virginia Tech (Virginia Polytechnic Institute and State University)., John Redd Hutcheson ( January 13 , 1886 -- January 13 , 1962 ) was the ninth President of Virginia Tech. He served from January 12 , 1945 to August 12 , 1947 . VPI alumnus John Redd Hutcheson , known as Dr. Jack , agreed to take the job as president of VPI only for a few years . A former school teacher , high school principal , and university instructor , Hutcheson started working for the Virginia Agricultural Extension Service in 1914 as a livestock specialist and became its director in 1919 , developing a national reputation as an agricultural leader . Shortly after the affable Hutcheson took over the presidency on August 14 , 1945 , Japan surrendered to end World War II , and a two - day celebration ensued . When the fall quarter began soon thereafter , enrollment nearly doubled that of the previous quarter . The new president worked to prepare the campus for the influx of returning veterans as the college moved from wartime to peacetime conditions . The veterans generally had no interest in joining the corps of cadets , and for the first time , during winter quarter 1946 , civilians outnumbered cadets on campus . With the explosion in civilian students , 3,100 living on campus and another 900 day students came a need for housing . To help resolve the problem for married veterans , the college installed a trailer court that students called Vetsville surrounding the Solitude House , which was converted into a community center to serve the trailer court residents . Two additional trailer courts that students called Cassell Heights after financial and business manager Stuart K. Cassell followed in the area east of present - day Cassell Coliseum . The college also rented dormitory space at the Radford Arsenal to house other students and converted several buildings there into classrooms ; the new location became known as Rad - Tech. During this period , the board of visitors created a vice president position , which was filled by Walter S. Newman , to handle curriculum development . Hutcheson himself created an office of admissions to assist C. P. `` Sally '' Miles , dean of the college , with the thousands of applications for admission that poured into the school . Under Hutcheson , VPI added a master of science in applied mechanics , permitted day students to drive their own automobiles to and from designated campus parking lots , resumed activities including football , and student organizations that had been dropped during World War II , and created an office of student affairs . The board of visitors approved the final plans for an alumni war memorial and the proposed Mall leading to the memorial . The school received the first invitation ever issued to a Virginia college team to play in a bowl game , the Sun Bowl on New Year 's Day in 1947 . In December 1946 Hutcheson was hospitalized , and Newman , working with Cassell , took over his duties . In May 1947 Newman was named acting president . Concerned about Hutcheson 's health , the board voted on August 12 to relieve him of his presidential duties but elected him to the new position of chancellor and named Newman president , effective September 1 , 1947 . Hutcheson recovered , and in 1948 he became president of the newly established VPI Educational Foundation . He retired as chancellor in 1956 to devote full attention to the foundation , which he served until his death on January 23 , 1962 . Hutcheson Hall , an academic building on the Virginia Tech Campus is named in honor of Hutcheson ., Subject: john redd hutcheson, Relation: educated_at, Options: (A) undergraduate education (B) virginia polytechnic institute and state university

Answer: virginia polytechnic institute and state university


Question: 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

Question: Context: Testosterone is the primary male sex hormone and an anabolic steroid. In men, testosterone plays a key role in the development of male reproductive tissues such as the testis and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair. In addition, testosterone is essential for health and well-being, and for the prevention of osteoporosis. Insufficient levels of testosterone in men may lead to abnormalities including frailty and bone loss., South Asia or Southern Asia is a term used to represent the southern region of the Asian continent, which comprises the sub-Himalayan SAARC countries and, for some authorities, adjoining countries to the west and east. Topographically, it is dominated by the Indian Plate, which rises above sea level as Nepal and northern parts of India situated south of the Himalayas and the Hindu Kush. South Asia is bounded on the south by the Indian Ocean and on land (clockwise, from west) by West Asia, Central Asia, East Asia, and Southeast Asia., Enzymes are macromolecular biological catalysts. Enzymes accelerate, or catalyze, chemical reactions. The molecules at the beginning of the process upon which enzymes may act are called substrates and the enzyme converts these into different molecules, called products. Almost all metabolic processes in the cell need enzymes in order to occur at rates fast enough to sustain life. The set of enzymes made in a cell determines which metabolic pathways occur in that cell. The study of enzymes is called "enzymology"., Asia-Pacific or Asia Pacific (abbreviated as APAC, Asia-Pac, AsPac, APJ, JAPA or JAPAC) is the part of the world in or near the Western Pacific Ocean. The region varies in size depending on which context, but it typically includes much of East Asia, South Asia, Southeast Asia, and Oceania., Dihydrotestosterone (DHT), or 5-dihydrotestosterone (5-DHT), also known as 5-androstan-17-ol-3-one, is an endogenous androgen sex steroid and hormone. The enzyme 5-reductase catalyzes the formation of DHT from testosterone in certain tissues including the prostate gland, seminal vesicles, epididymides, skin, hair follicles, liver, and brain. This enzyme mediates reduction of the C4-5 double bond of testosterone. Relative to testosterone, DHT is considerably more potent as an agonist of the androgen receptor (AR)., Southeast Asia or Southeastern Asia is a subregion of Asia, consisting of the countries that are geographically south of China, east of India, west of New Guinea and north of Australia. The region lies near the intersection of geological plates, with heavy seismic and volcanic activity. Southeast Asia consists of two geographic regions:, 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., East Asia is the eastern subregion of the Asian continent, which can be defined in either geographical or ethno-cultural terms. Geographically and geopolitically, it includes China, Hong Kong, and Macao; Mongolia and Taiwan; North and South Korea; and Japan; it covers about , or about 28% of the Asian continent, about twice the area of Europe., A steroid is an organic compound with four rings arranged in a specific configuration. Examples include the dietary lipid cholesterol, the sex hormones estradiol and testosterone and the anti-inflammatory drug dexamethasone. Steroids have two principal biological functions: certain steroids (such as cholesterol) are important components of cell membranes which alter membrane fluidity, and many steroids are signaling molecules which activate steroid hormone receptors., An agonist is a chemical that binds to a receptor and activates the receptor to produce a biological response. Whereas an agonist causes an action, an antagonist blocks the action of the agonist and an inverse agonist causes an action opposite to that of the agonist., Mesterolone is an orally applicable androgen and dihydrotestosterone ( DHT ) derivative . It is sold under the brand name Proviron ( as Provironum in Asia - Pacific region ) , by Bayer Schering Pharma ( earlier by Schering ) . In the late 70s and early 80s , it was used with some success in controlled studies of men suffering from various forms of depression . Mesterolone is a relatively weak androgen and rarely used for replacement therapies ., 5-reductases, also known as 3-oxo-5-steroid 4-dehydrogenases, are enzymes involved in steroid metabolism. They participate in 3 metabolic pathways: bile acid biosynthesis, androgen and estrogen metabolism. There are three isoenzymes of 5-reductase, which vary in different tissues with age., 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., The liver is a vital organ of vertebrates and some other animals. In the human, it is located in the upper right quadrant of the abdomen, below the diaphragm. The liver has a wide range of functions, including detoxification of various metabolites, protein synthesis, and the production of biochemicals necessary for digestion., 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., Androgen (from Greek "andro" meaning male human being), also called androgenic hormone or testoid, is any natural or synthetic compound, usually a steroid hormone, that stimulates or controls the development and maintenance of male characteristics in vertebrates by binding to androgen receptors. This includes the activity of the primary male sex organs and development of male secondary sex characteristics. Androgens were first discovered in 1936. Androgens increase in both boys and girls during puberty. Androgens are also the original anabolic steroids and the precursor of all estrogens. The primary and most well-known androgen is testosterone. Dihydrotestosterone (DHT) and androstenedione are less known generally, but are of equal importance in male development. DHT in the embryo life causes differentiation of penis, scrotum and prostate. Later in life DHT contributes to balding, prostate growth and sebaceous gland activity. Although androgens are described as male sex hormones, both males and females have them to varying degrees, as is also true of estrogens. They are one of three types of sex hormones, the others being estrogens like estradiol and progestogens like progesterone., Oceania (or ), also known as Oceanica, is a region centred on the islands of the tropical Pacific Ocean. Opinions of what constitutes Oceania range from its three subregions of Melanesia, Micronesia, and Polynesia to, more broadly, the entire insular region between Southeast Asia and the Americas, including Australasia and the Malay Archipelago., The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. The brain is located in the head, usually close to the sensory organs for senses such as vision. The brain is the most complex organ in a vertebrate's body. In a human, the cerebral cortex contains approximately 1533 billion neurons, each connected by synapses to several thousand other neurons. These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells., The androgen receptor (AR), also known as NR3C4 (nuclear receptor subfamily 3, group C, member 4), is a type of nuclear receptor that is activated by binding either of the androgenic hormones, testosterone, or dihydrotestosterone in the cytoplasm and then translocating into the nucleus. The androgen receptor is most closely related to the progesterone receptor, and progestins in higher dosages can block the androgen receptor., A double bond in chemistry is a chemical bond between two chemical elements involving four bonding electrons instead of the usual two. The most common double bond, that is between two carbon atoms, can be found in alkenes. Many types of double bonds exist between two different elements. For example, in a carbonyl group with a carbon atom and an oxygen atom. Other common double bonds are found in azo compounds (N=N), imines (C=N) and sulfoxides (S=O). In skeletal formula the double bond is drawn as two parallel lines (=) between the two connected atoms; typographically, the equals sign is used for this. Double bonds were first introduced in chemical notation by prominent Russian chemist Alexander Butlerov., A hair follicle is a mammalian skin organ that produces hair. Hair production occurs in phases, including growth (anagen), cessation (catagen), and rest (telogen) phases. Stem cells are responsible for hair production. The shape of the hair follicle has an effect on the hair shape and texture of the individual's hair., Subject: mesterolone, Relation: has_part, Options: (A) 0 (B) a (C) alexander (D) antarctica (E) arctic ocean (F) asia (G) brain (H) c (I) carbon (J) cell (K) chemistry (L) earth (M) eurasia (N) europe (O) formation (P) group (Q) human (R) key (S) lead (T) liver (U) malay archipelago (V) member (W) metabolism (X) micronesia (Y) o (Z) oceania ([) one (\) organ (]) organism (^) outer (_) pacific ocean (`) polynesia (a) s (b) set (c) south korea (d) speed (e) stem (f) temperature (g) the americas
