Example Input: 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., 20 mm 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 7.62×51mm NATO, 7.62×54mmR, 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 5.5 mm (.22 inch) 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

Example Input: Context: Ion Media Networks, Inc. (formerly known as Paxson Communications Corporation) is an American broadcasting company that owns and operates over 60 television stations in most major American markets (through its television stations group, Ion Media Television), as well as a digital sub-channel through that group & a major commercial television network. It is now a privately owned company., WQPX - TV is the Ion Television affiliate for Scranton / Wilkes - Barre , Pennsylvania . It is owned and operated by ion Media Networks ( the former Paxson Communications ) ., Wilkes-Barre (or ) is a city in the Commonwealth of Pennsylvania and the county seat of Luzerne County. It is one of the principal cities in the "ScrantonWilkes-BarreHazleton, PA Metropolitan Statistical Area". Located at the center of the Wyoming Valley, it is second in size only to the nearby city of Scranton. The ScrantonWilkes-BarreHazleton, PA Metropolitan Statistical Area had a population of 563,631 as of the 2010 Census, making it the fourth-largest metro/statistical area in the state of Pennsylvania. Wilkes-Barre and the surrounding Wyoming Valley are framed by the Pocono Mountains to the east, the Endless Mountains to the west, and the Lehigh Valley to the south. The Susquehanna River flows through the center of the valley and defines the northwestern border of the city., The Susquehanna River (Lenape: Siskëwahane) is a major river located in the northeastern United States. At long, it is the longest river on the American east coast that drains into the Atlantic Ocean. With its watershed, it is the 16th-largest river in the United States, and the longest river in the continental United States without commercial boat traffic today. In the Canal Era, navigation improvements were made to enhance the river for barge shipping of bulk goods by water transport on the Pennsylvania Canal; competition from faster transport via the railroad industry resulted in reducing the maintenance on the river.
The Susquehanna rises and flows through New York, Pennsylvania, and Maryland into the Chesapeake Bay. It forms from two main branches: the "North Branch", which rises in upstate New York and is regarded by federal mapmakers as the main branch, and the West Branch Susquehanna. Both of these waterways were improved by navigations throughout the 1820s and 1830s as the Pennsylvania Canal. Together with facilities of the Allegheny Portage Railroad, loaded barges were transferred from the canal and hoisted across the mountain ridge into the Pittsburgh area. The 82-mile Union Canal was completed in 1828 to connect Schuylkill River in Reading to the Susquehanna above Harrisburg. An 82-mile leg connecting the Susquehanna with the Delaware River was instead developed as the Philadelphia and Columbia Railroad, built by the Pennsylvania Canal Commission. The shorter West Branch, which rises in western Pennsylvania, joins the main stem of the Susquehanna near Northumberland in central Pennsylvania., The Endless Mountains are a chain of mountains in northeastern Pennsylvania. The Endless Mountains region includes Bradford, Sullivan, Susquehanna, and Wyoming counties. The highest peak in the region is the North Knob of Elk Mountain at 2693 feet (821 meters)., Ion Television is an American broadcast, cable, and satellite television network that is owned by Ion Media Networks.

Broadcasting began with AM radio, which came into popular use around 1920 with the spread of vacuum tube radio transmitters and receivers. Before this, all forms of electronic communication (early radio, telephone, and telegraph) were one-to-one, with the message intended for a single recipient. The term "broadcasting", borrowed from the agricultural method of sowing seeds in a field by casting them broadly about, was coined by either KDKA manager Frank Conrad or RCA historian George Clark around 1920 to distinguish this new activity of "one-to-many" communication; a single radio station transmitting to multiple listeners., Subject: wqpx-tv, Relation: inception, Options: (A) 1 (B) 1828 (C) 1920 (D) 1998 (E) 2007 (F) 563 (G) 60 (H) 821
