Context: A chain gun is a type of machine gun or autocannon that uses an external source of power to cycle the weapon rather than diverting energy from the cartridge , and does so via a continuous loop of chain similar to that used on a motorcycle or bicycle . '' Chain gun '' is a registered trademark of Alliant Techsystems Inc. for a chain - powered weapon ., The word bullet is a firearm term. A bullet is a projectile expelled from the barrel of a firearm. The term is from Middle French and originated as the diminutive of the word boulle (boullet) which means "small ball." Bullets are made of a variety of materials. They are available singly as they would be used in muzzle loading and cap and ball firearms, as part of a paper cartridge, and much more commonly as a component of metallic cartridges. Bullets are made in a large numbers of styles and constructions depending on how they will be used. Many bullets have specialized functions, such as hunting, target shooting, training, defense, and warfare. , An autocannon or automatic cannon is a large, fully automatic, rapid-fire projectile weapon that fires armour-piercing or explosive shells, as opposed to the bullet fired by a machine gun. Autocannons often have a larger calibre than a machine gun (e.g., 20mm or greater), but are usually smaller than a field gun or other artillery. When used on its own, the word "autocannon" indicates a single-barrel weapon. When multiple rotating barrels are involved, the word "rotary" is added, and such a weapon is referred to as a "rotary autocannon." Modern autocannons are typically not single soldier-portable or stand-alone units, rather they are usually vehicle-mounted, aircraft-mounted, or boat-mounted, or even remote-operated as in some naval applications. As such, ammunition is typically fed from a belt to reduce reloading or for a faster rate of fire, but a magazine remains an option. They can use a variety of ammunition: common shells include high-explosive dual-purpose types (HEDP), any variety of armour-piercing (AP) types, such as composite rigid (APCR) or discarding sabot types (APDS)., A battle rifle is a military service rifle that fires a full-power rifle cartridge, such as 7.6251mm NATO, 7.6254mmR, 7.92x57mm Mauser, .303 British, or .30-06 Springfield. Compared to assault rifles and their intermediate cartridges, the higher-caliber rounds provide greater power and range, though they have greater weight and produce stronger recoil, making them less than ideal for fully automatic fire., A field gun is an artillery piece. Originally the term referred to smaller guns that could accompany a field army on the march and when in combat could be moved about the battlefield in response to changing circumstances (field artillery), as opposed to guns installed in a fort (garrison artillery/coastal artillery), or to siege cannon or mortars which were too large to be moved quickly, and would be used only in a prolonged siege., A submachine gun (SMG) is an air-cooled, magazine-fed, automatic carbine designed to fire pistol cartridges. The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun., Rate of fire is the frequency at which a specific weapon can fire or launch its projectiles. It is usually measured in rounds per minute (RPM or round/min), or rounds per second (RPS or round/s)., A machine gun is a fully automatic mounted or portable firearm, designed to fire bullets in quick succession from an ammunition belt or magazine, typically at a rate of 300 to 1800 rounds per minute. Fully automatic firearms are generally categorized as submachine guns, assault rifles, battle rifles, automatic shotguns, machine guns, or autocannons. Machine guns with multiple rotating barrels are referred to as "rotary machine guns"., An automatic shotgun is an automatic firearm that fires shotgun shells and uses some of the energy of each shot to automatically cycle the action and load a new round. It will fire repeatedly until the trigger is released or ammunition runs out. Automatic shotguns have a very limited range, but provide tremendous firepower at close range., A shotgun (also known as a scattergun, or historically as a fowling piece) is a firearm that is usually designed to be fired from the shoulder, which uses the energy of a fixed shell to fire a number of small spherical pellets called shot, or a solid projectile called a slug. Shotguns come in a wide variety of sizes, ranging from 5.5mm (.22inch) bore up to bore, and in a range of firearm operating mechanisms, including breech loading, single-barreled, double or combination gun, pump-action, bolt-, and lever-action, semi-automatic, and even fully automatic variants., Artillery is a class of large military weapons built to fire munitions far beyond the range and power of infantry's small arms. Early artillery development focused on the ability to breach fortifications, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility providing the largest share of an army's total firepower., An assault rifle is a selective-fire rifle that uses an intermediate cartridge and a detachable magazine. Assault rifles were first used during World War II. Though Western nations were slow to accept the assault rifle concept after World War II, by the end of the 20th century they had become the standard weapon in most of the world's armies, replacing semi-automatic rifles, battle rifles and sub-machine guns in most roles. Examples include the StG 44, AK-47 and the M16 rifle., Subject: chain gun, Relation: subclass_of, Options: (A) ability (B) action (C) ammunition (D) army (E) artillery (F) assault rifle (G) autocannon (H) battle (I) battle rifle (J) belt (K) bullet (L) cannon (M) class (N) energy (O) field gun (P) fire (Q) firearm (R) fort (S) gun (T) hunting (U) infantry (V) lighter (W) machine (X) magazine (Y) march (Z) military ([) option (\) part (]) power (^) projectile (_) rate (') rifle (a) service (b) shooting (c) shot (d) shotgun (e) single (f) solid (g) submachine gun (h) technology (i) term (j) variety (k) vehicle (l) weapon (m) word

Context: The Canadian titles debate has been ongoing since the presentation to the Canadian House of Commons of the Nickle Resolution in 1917. This resolution marked the earliest attempt to establish a Canadian government policy requesting the sovereign not to grant knighthoods, baronetcies, and peerages to Canadians and set the precedent for later policies restricting Canadians from accepting titles from foreign countries. Dissatisfaction with the British honours system led to the gradual creation of a separate system for Canada., Louise Lecavalier , OC ( born October 3 , 1958 ) is a Canadian dancer , known as one of the icons of Canadian contemporary dance . Lecavalier was born and raised in Montreal , Canada . She began her professional dance career at the age of eighteen when she joined Le Groupe Nouvelle Aire . It was there that she met Edouard Lock . Lecavalier became Lock 's main character and inspiration in his company La La La Human Steps . With her mane of platinum dreadlocks , her physical power and her mastery of the full - body barrel jump , which looks like a horizontal pirouette , her image was a signature for the company . She was the perfect embodiment of Lock 's frenetic and technically punishing androgynous aesthetic in works such as Human Sex ( 1985 ) and Infante , c'est destroy ( 1991 ) . She joined La La La Human Steps in 1981 for its production of Oranges and went on to perform in each of the company 's productions up until Salt in 1998 . In 1985 , Louise Lecavalier became the first Canadian to win a Bessie Award in New York for her performance in Businessman in the Process of Becoming an Angel ( 1983 ) . The London Times critic found Lock 's '' extravagant '' play poor but stated that there were '' ... two women who seemed quite skilled at performing various odd dance steps ; the fair - haired one ( Louise Lecavalier ) had a pleasing bravado whenever the production gave her half a chance . '' She danced in Human Sex ( 1985 ) , New Demons ( 1987 ) , Infante , c'est destroy ( 1991 ) and finally , 2 ( 1995 ) and Salt ( 1998 ) . Lecavalier also participated in each of La La La 's major collaborations , including David Bowie 's Sound + Vision Tour in 1990 and Fame ' 90 music video , The Yellow Shark concerts , performed by Frank Zappa and Germany 's Ensemble Modern in Frankfurt , Berlin , and Vienna in 1992 , and the film Inspirations from director Michael Apted in 1996 . In May 1999 , Louise Lecavalier received the Jean A. Chalmers National Award , Canada 's most distinguished dance prize . In 2003 , she appeared with Tedd Robinson in Lula and the Sailor as part of a concert of duets choreographed by Robinson . In the winter of 2005 , she co-produced Cobalt Rouge with the National Arts Centre in Ottawa , the Biennale di Venezia and Theatre de la Ville in Paris . The work features Lecavalier with dancers Marc Boivin , Masaharu Imazu , and Tedd Robinson , and musician / composer Yannick Rieu . Lecavalier has been a guest teacher at New York University on several occasions and continues to perform as an independent artist . In 2008 , she was made an Officer of the Order of Canada . On April 7 , 2010 she was awarded the Order of Canada . On December 7 , 2012 , her piece '' So Blue '' premiered in Dusseldorf . It was her first dance choreography . In May 2014 , Lecavalier received the Governor General 's Performing Arts Award for Lifetime Artistic Achievement in dance . The award is Canada 's highest honour in the performing arts ., An earl is a member of the nobility. The title is Anglo-Saxon in origin, akin to the Scandinavian form jarl, and meant "chieftain", particularly a chieftain set to rule a territory in a king's stead. In Scandinavia, it became obsolete in the Middle Ages and was replaced by duke ("hertig"/"hertug"/"hertog"). In later medieval Britain, it became the equivalent of the continental count (in England in the earlier period, it was more akin to a duke; in Scotland it assimilated the concept of mormaer). However, earlier in Scandinavia, "jarl" could also mean a sovereign prince. For example, the rulers of several of the petty kingdoms of Norway had the title of "jarl" and in many cases they had no less power than their neighbours who had the title of king. Alternative names for the "Earl/Count" rank in the nobility structure are used in other countries, such as Hakushaku during the Japanese Imperial era., A knight is a person granted an honorary title of "knighthood" by a monarch or other political leader for service to the monarch or country, especially in a military capacity. Historically, in Europe, knighthood was conferred upon mounted warriors. During the High Middle Ages, knighthood was considered a class of lower nobility. By the Late Middle Ages, the rank had become associated with the ideals of chivalry, a code of conduct for the perfect courtly Christian warrior. Often, a knight was a vassal who served as a fighter for a lord, with payment in the form of land holdings. The lords trusted the knights, who were skilled in battle on horseback. Since the early modern period, the title of knight is purely honorific, usually bestowed by a monarch, as in the British honours system, often for non-military service to the country. The modern female equivalent in the United Kingdom is Dame., Dance is a performance art form consisting of purposefully selected sequences of human movement. This movement has aesthetic and symbolic value, and is acknowledged as dance by performers and observers within a particular culture. Dance can be categorized and described by its choreography, by its repertoire of movements, or by its historical period or place of origin., Choreography is the art or practice of designing sequences of movements of physical bodies (or their depictions) in which motion, form, or both are specified. "Choreography" may also refer to the design itself. A choreographer is one who creates choreographies by practicing the art of choreography, a process known as "choreographing". Choreography is used in a variety of fields, including musical theater, cheerleading, cinematography, gymnastics, fashion shows, ice skating, marching band, show choir, theatre, synchronized swimming, cardistry, video game production and animated art. In the performing arts, choreography applies to human movement and form. In dance, choreography is also known as dance choreography or "dance composition"., Subject: louise lecavalier, Relation: occupation, Options: (A) canada (B) choreographer (C) duke (D) knight (E) leader (F) member (G) military (H) monarch (I) nobility (J) sovereign

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., Phractura is a genus of loach catfishes ( order Siluriformes ) that occur in Africa . Phractura species are elongated fish with a long caudal peduncle and bony scutes on the sides , back , and belly . Phractura species are often associated with vegetation . Phractura species , like other genera in Doumeinae , have a mouth modified into a suckermouth that allows it to clean to the objects and scrape the surface of the substrate ., 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., The loach catfishes are a family, Amphiliidae, of catfishes (order Siluriformes). They are widespread in tropical Africa, but are most common in streams at high elevations; most species are able to cling to rocks in fast-flowing streams. The 13 genera contain 68 species., 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., Subject: phractura, Relation: parent_taxon, Options: (A) amphiliidae (B) animal (C) homo
