Context: A regnal name, or reign name, is a name used by some monarchs and popes during their reigns, and used subsequently to refer to them. The term is simply the adjective "regnal", of or relating to a reign, monarch, or kingdom, modifying "name". Since ancient times, monarchs have frequently, but not always, chosen to use a different name from their original name when they accede to the monarchy.
The regnal name is usually followed by a regnal number (ordinal), usually written as a Roman numeral (VI rather than 6), to provide a unique identification for that monarch among other monarchs of that realm. In some cases, the monarch has more than one regnal name, but the regnal number is based on only one of those names, for example Charles X Gustav of Sweden, George Tupou V of Tonga. If a monarch reigns in more than one realm, he or she may carry different ordinals in each one, as they are each assigned chronologically, and some realms may have had different numbers of rulers of the same regnal name previously. For example, the same person was both King James I of England (along with Ireland) and King James VI of Scotland., 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 stage name, also called a screen name, is a pseudonym used by performers and entertainers such as actors, comedians, and musicians., A name is a term used for identification. Names can identify a class or category of things, or a single thing, either uniquely, or within a given context. A personal name identifies, not necessarily uniquely, a "specific" individual human. The name of a specific entity is sometimes called a proper name (although that term has a philosophical meaning also) and is, when consisting of only one word, a proper noun. Other nouns are sometimes called "common names" or (obsolete) "general names". A name can be given to a person, place, or thing; for example, parents can give their child a name or a scientist can give an element a name., A pseudonym (and ) or alias is a name that a person or group assumes for a particular purpose, which can differ from their original or true name (orthonym). Pseudonyms include stage names and user names (both called "screen names"), ring names, pen names, nicknames, aliases, superhero identities and code names, gamer identifications, and regnal names of emperors, popes, and other monarchs. Historically, they have often taken the form of anagrams, Graecisms, and Latinisations, although there are many other methods of choosing a pseudonym., Anthony Peter "Tony" Hatch (born 30 June 1939), also credited as Fred Nightingale and Mark Anthony, is an English composer for musical theatre and television. He is also a noted songwriter, pianist, arranger and producer., A ring name is a stage name used by a professional wrestler, martial artist, or a boxer. While some ring names may have a fictitious first name and surname, others may simply be a nickname from the moves that they do or their talents in the ring., An anagram is direct word switch or word play, the result of rearranging the letters of a word or phrase to produce a new word or phrase, using all the original letters exactly once; for example, the word anagram can be rearranged into nag-a-ram. Someone who creates anagrams may be called an "anagrammatist". The original word or phrase is known as the "subject" of the anagram. Anagrams are often used as a form of mnemonic device as well., A nickname is a substitute for the proper name of a familiar person, place, or thing, for affection or ridicule., A monarch is the sovereign head of state in a monarchy. A monarch may exercise the highest authority and power in the state, or others may wield that power on behalf of the monarch. Typically a monarch either personally inherits the lawful right to exercise the state's sovereign rights (often referred to as "the throne" or "the crown") or is selected by an established process from a family or cohort eligible to provide the nation's monarch. Alternatively, an individual may become monarch by conquest, acclamation or a combination of means. A monarch usually reigns for life or until abdication. , The pope (from "pappas", a child's word for "father") is the Bishop of Rome and, therefore, the leader of the worldwide Catholic Church. The primacy of the Roman bishop is largely derived from his role as the traditional successor to Saint Peter, to whom Jesus is supposed to have given the keys of Heaven and the powers of "binding and loosing", naming him as the "rock" upon which the church would be built. The current pope is Francis, who was elected on 13 March 2013, succeeding Benedict XVI., In modern popular fiction, a superhero (sometimes rendered super-hero or super hero) is a type of costumed heroic character who possesses supernatural or superhuman powers and who is dedicated to fighting crime, protecting the public, and usually battling supervillains. A female superhero is sometimes called a superheroine (also rendered super-heroine or super heroine). Fiction centered on such characters, especially in American comic books since the 1930s, is known as superhero fiction., `` Sugar and Spice '' is a 1963 song by Merseybeat band The Searchers written by Tony Hatch under the pseudonym Fred Nightingale . It made number two on the UK charts ( on Pye ) and number 44 in the USA charts . A chorus `` Sugar and spice and all things nice '' contains a reference to a nursery rhyme What Are Little Boys Made Of ? . Covers included a hit for The Cryan ' Shames , whose version was released in 1966 on the Chicago - based Destination label . The song became a local and regional hit for the band and finally peaked at number 49 on the Billboard Hot 100 chart . The Cryan ' Shames ' recording of the song was included on the influential 1972 compilation Nuggets : Original Artyfacts from the First Psychedelic Era , 1965 -- 1968 ., Subject: sugar and spice , Relation: instance_of, Options: (A) adjective (B) bishop (C) character (D) child (E) class (F) combination (G) conquest (H) crown (I) distance (J) england (K) fiction (L) group (M) head of state (N) hero (O) human (P) june (Q) march (R) may (S) monarch (T) name (U) nation (V) nickname (W) number (X) numeral (Y) page (Z) pen ([) person (\) personal name (]) presentation (^) proper noun (_) pseudonym (`) publisher (a) ring (b) role (c) saint (d) single (e) stage (f) state (g) superhero (h) surname (i) television (j) the crown (k) user (l) word (m) word play (n) work

Context: Protist is an informal term for any eukaryotic organism that is not an animal, plant or fungus. The protists do not form a natural group, or clade, but are often grouped together for convenience, like algae or invertebrates. In some systems of biological classification, such as the popular 5-kingdom scheme proposed by Robert Whittaker in 1969, the protists make up a kingdom called Protista, composed of "organisms which are unicellular or unicellular-colonial and which form no tissues.", The metamonads are a large group of flagellate amitochondriate protozoa . Their composition is not entirely settled , but they include the retortamonads , diplomonads , and possibly the parabasalids and oxymonads as well . These four groups are all anaerobic , occurring mostly as symbiotes of animals ., A flagellate is a cell or organism with one or more whip-like organelles called flagella. The word "flagellate" also describes a particular construction (or level of organization) characteristic of many protists (eukaryotic organisms) and their means of motion. The term presently does not imply any specific relationship or classification of the organisms that possess flagellae. However, the term "flagellate" is included in other terms (such as "dinoflagellate" and "choanoflagellata") which are more formally characterized., The retortamonads are a small group of flagellates, most commonly found in the intestines of animals as commensals, although a free-living species called the "Chilomastix cuspidata" exists. They are grouped under the taxon, Archezoa. They are usually around 5-20 m in length, and all of their small subunit ribosomal RNA gene sequences are very similar to each other. There are two genera: "Retortamonas" with two flagella, and "Chilomastix" with four. In both cases there are four basal bodies anterior to a prominent feeding groove, and one flagellum is directed back through the cell, emerging from the groove., The dinoflagellates (Greek  "dinos" "whirling" and Latin "flagellum" "whip, scourge") are a large group of flagellate protists that constitute the phylum Dinoflagellata. Most are marine plankton, but they are common in freshwater habitats, as well. Their populations are distributed depending on temperature, salinity, or depth. Many dinoflagellates are known to be photosynthetic, but a large fraction of these are in fact mixotrophic, combining photosynthesis with ingestion of prey (phagotrophy). In terms of number of species, dinoflagellates form one of the largest groups of marine eukaryotes, although this group is substantially smaller than the diatoms. Some species are endosymbionts of marine animals and play an important part in the biology of coral reefs. Other dinoflagellates are unpigmented predators on other protozoa, and a few forms are parasitic (see for example "Oodinium", "Pfiesteria"). Some dinoflagellates produce resting stages, called dinoflagellate cysts or dinocysts, as part of their lifecycles., Subject: metamonad, Relation: instance_of, Options: (A) animal (B) biology (C) cell (D) clade (E) classification (F) construction (G) dinos (H) group (I) organism (J) organization (K) plant (L) taxon (M) term (N) whip

Context: The AEK-971 is a Soviet / Russian selective fire assault rifle that was developed at the Kovrov Mechanical Plant (KMZ) by chief designer Sergey Koksharov in the late 1970s and 1980s. The primary model, the AEK-971, uses the 5.45×39mm round fed from standard 30-round or larger box magazines used by the AK-74, AK-74M, and similar weapons., The 5.45×39mm cartridge is a rimless bottlenecked rifle cartridge. It was introduced into service in 1974 by the Soviet Union for use with the new AK-74 assault rifle. It gradually supplemented, then largely replaced the 7.62×39mm round in service., Kovrov is a city in Vladimir Oblast, Russia, located on the right bank of the Klyazma River (a tributary of the Oka). Kovrov's population as of the 2010 Census was 145,214; down from 155,499 recorded in the 2002 Census, and further down from 159,942 recorded in the 1989 Census). In terms of population, it is the second-largest city in Vladimir Oblast (after Vladimir). In 1977, Kovrov's population had been estimated at 140,000., The AK-107 is a Russian 5.45×39mm assault rifle developed from the AK-100-series. It features a "balanced" operating system, similar to that used in the AEK-971. In this case, the designation AK does not indicate "Avtomat Kalashnikova" but "Alexandrov/Kalashnikov". The revised designation indicates the incorporation of a new gas system, designed by Youriy Alexandrov, for Kalashnikov-pattern rifles., The AO - 38 is a 5.45 × 39mm assault rifle and AK derivative designed by Peter Andreevich Tkachev and first to use the Balanced Automatic Recoil System ( BARS ) to improve stability giving better accuracy over AK - 74 's . Its derivatives are the AK - 107 and AEK - 971 ., Russia (from the  Rus'), also officially known as the Russian Federation, is a country in Eurasia. At , Russia is the largest country in the world by surface area, covering more than one-eighth of the Earth's inhabited land area, and the ninth most populous, with over 140 million people at the end of March 2016. The European western part of the country is much more populated and urbanised than the eastern, about 77% of the population live in European Russia. Russia's capital Moscow is one of the largest cities in the world, other major urban centers include Saint Petersburg, Novosibirsk, Yekaterinburg, Nizhny Novgorod and Samara., The AK-74 (Russian: or "Kalashnikov automatic rifle model 1974") is an assault rifle developed in the early 1970s by Russian designer Mikhail Kalashnikov as the replacement for the earlier AKM (itself a refined version of the AK-47). It uses a smaller 5.45×39mm cartridge, replacing the 7.62×39mm chambering of earlier Kalashnikov-pattern weapons., The AK-47, or AK as it is officially known (also known as the Kalashnikov) is a selective-fire (semi-automatic and automatic), gas-operated 7.62×39 mm assault rifle, developed in the Soviet Union by Mikhail Kalashnikov. It is officially known in the Soviet documentation as "Avtomat Kalashnikova"., Subject: ao-38 assault rifle, Relation: country_of_origin, Options: (A) russia (B) soviet union
