[EX Q]: Context: Lake Erie is the fourth-largest lake (by surface area) of the five Great Lakes in North America, and the thirteenth-largest globally if measured in terms of surface area. It is the southernmost, shallowest, and smallest by volume of the Great Lakes and therefore also has the shortest average water residence time. At its deepest point Lake Erie is deep. Lake Erie's northern shore is bounded by the Canadian province of Ontario, with the U.S. states of Ohio, Pennsylvania, and New York on its southern and easternmost shores and Michigan on the west. These jurisdictions divide the surface area of the lake by water boundaries. The lake was named by the Erie people, a Native Americans people who lived along its southern shore. That Iroquoian tribe called it ""Erige"" "("cat")" because of its unpredictable and sometimes violently dangerous nature. It is a matter of conjecture whether the lake was named after the tribe, or if the tribe was called ""Erie"" because of its proximity to the lake., The hyphen () is a punctuation mark used to join words and to separate syllables of a single word. The use of hyphens is called hyphenation. The hyphen should not be confused with dashes (, , , ), which are longer and have different uses, or with the minus sign (), which is also longer in some contexts., Maryland is a state located in the Mid-Atlantic region of the United States, bordering Virginia, West Virginia, and Washington, D.C. to its south and west; Pennsylvania to its north; and Delaware to its east. The state's largest city is Baltimore, and its capital is Annapolis. Among its occasional nicknames are "Old Line State", the "Free State", and the "Chesapeake Bay State". The state is named after Henrietta Maria of France, the wife of Charles I of England. , ZIP Codes are a system of postal codes used by the United States Postal Service (USPS) since 1963. The term "ZIP", an acronym for Zone Improvement Plan, was chosen to suggest that the mail travels more efficiently, and therefore more quickly (zipping along), when senders use the code in the postal address. The basic format consists of five numerical digits. An extended ZIP+4 code, introduced in 1983, includes the five digits of the ZIP Code, a hyphen, and four additional digits that determine a more specific location within a given ZIP Code., A digit is a numeric symbol (such as "2" or "5") used in combinations (such as "25") to represent numbers (such as the number 25) in positional numeral systems. The name "digit" comes from the fact that the 10 digits (Latin "digiti" meaning fingers) of the hands correspond to the 10 symbols of the common base 10 numeral system, i.e. the decimal (ancient Latin adjective "decem" meaning ten) digits., The mail or post is a system for physically transporting documents and other small packages; or, the postcards, letters, and parcels themselves. A postal service can be private or public, though many governments place restrictions on private systems. Since the mid-19th century national postal systems have generally been established as government monopolies with a fee on the article prepaid. Proof of payment is often in the form of adhesive postage stamps, but postage meters are also used for bulk mailing. Modern private postal systems are typically distinguished from national postal agencies by the names "courier" or "delivery service"., Pennsylvania (Pennsylvania German: "Pennsylvaani"), officially the Commonwealth of Pennsylvania, is a state located in the northeastern and Mid-Atlantic regions of the United States.

It is home to the nation's capital city, Ottawa, and the nation's most populous city, Toronto., The Appalachian Mountains, often called the Appalachians, are a system of mountains in eastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. It once reached elevations similar to those of the Alps and the Rocky Mountains before naturally occurring erosion. The Appalachian chain is a barrier to east-west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most roads running east or west., Subject: list of places in pennsylvania: b, Relation: is_a_list_of, Options: (A) ancient (B) baron (C) capital (D) century (E) city (F) governor (G) household income (H) lake (I) location (J) name (K) people (L) postal code (M) single (N) state (O) symbol (P) system (Q) term

He has won several prestigious accolades for his contributions to the video game industry., The Commodore 64, also known as the C64, C-64, C= 64, or occasionally CBM 64 or VIC-64 in Sweden, is an 8-bit home computer introduced in January 1982 by Commodore International. It is listed in the Guinness World Records as the highest-selling single computer model of all time, with independent estimates placing the number sold between 10 and 17 million units. Volume production started in early 1982, marketing in August for . Preceded by the Commodore VIC-20 and Commodore PET, the C64 took its name from its of RAM. It had superior sound and graphical specifications compared to other earlier systems such as the Apple II and Atari 800, with multi-color sprites and a more advanced sound processor., A video game publisher is a company that publishes video games that they have either developed internally or have had developed by a video game developer. As with book publishers or publishers of DVD movies, video game publishers are responsible for their product's manufacturing and marketing, including market research and all aspects of advertising., Airborne Ranger is a video game developed and released by MicroProse in 1987 for the Amstrad CPC, Commodore 64, ZX Spectrum, and MS-DOS. It is an action game in which a sole U.S. Army Ranger is sent to infiltrate the enemy territory to complete various objectives. Amiga and Atari ST versions were released few years later and were a wholly independent development effort and different from gameplay standpoint., The action game is a video game genre that emphasizes physical challenges, including handeye coordination and reaction-time. The genre includes diverse subgenres such as fighting games, shooter games and platform games which are widely considered the most important action games, though some real-time strategy games are also considered to be action games., X-COM (sometimes stylized as "X-Com") is a science fiction video game franchise featuring an elite international organization tasked with countering alien invasions of Earth. The series began with the strategy video game "" created by Mythos Games and MicroProse in 1994. The original line up by MicroProse included six published and at least two cancelled games, as well as two novels. The "X-COM" series, in particular its original entry, achieved a sizable cult following and has influenced many other video games; including the creation of a number of clones, spiritual successors, and unofficial remakes., The ZX Spectrum is an 8-bit personal home computer released in the United Kingdom in 1982 by Sinclair Research Ltd.

Based on the Motorola 68000 family of microprocessors, the machine has a custom chipset with graphics and sound capabilities that were unprecedented for the price, and a pre-emptive multitasking operating system called AmigaOS. The Amiga provided a significant upgrade from earlier 8-bit home computers, including Commodore's own C64., A video game is an electronic game that involves human or animal interaction with a user interface to generate visual feedback on a video device such as a TV screen or computer monitor. The word "video" in "video game" traditionally referred to a raster display device, but as of the 2000s, it implies any type of display device that can produce two- or three-dimensional images. Some theorists categorize video games as an art form, but this designation is controversial., MS-DOS (; acronym for "Microsoft Disk Operating System") is a discontinued operating system for x86-based personal computers mostly developed by Microsoft. It was the most commonly used member of the DOS family of operating systems, and was the main operating system for IBM PC compatible personal computers during the 1980s and the early 1990s, when it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system by Microsoft Corporation., MicroProse was an American video game publisher and developer founded by "Wild" Bill Stealey and Sid Meier in 1982 as MicroProse Software Inc.

[EX Q]: Context: Infantry is the general branch of an army that engages in military combat on foot. As the troops who engage with the enemy in close-ranged combat, infantry units bear the largest brunt of warfare and typically suffer the greatest number of casualties during a military campaign. Historically, as the oldest branch of the combat arms, the infantry are the tip of the spear of a modern army, and continually undergo training that is typically more physically demanding and psychologically stressful than that of any other branch of the combat arms. Common representations of infantry fighting forces include the U.S. Army Infantry Branch, U.S. Marine Corps Infantry, Royal Canadian Infantry Corps, Infantry of the British Army, and the Royal Australian Corps of Infantry., Fortifications are military constructions or buildings designed for the defense of territories in warfare, and also used to solidify rule in a region during peace time. Humans have constructed defensive works for many thousands of years, in a variety of increasingly complex designs. The term is derived from the Latin "fortis" ("strong") and "facere" ("to make")., Self-propelled artillery (also called mobile artillery or locomotive artillery) is artillery equipped with its own propulsion system to move towards its target. Within the term are covered self-propelled guns (or howitzers) and rocket artillery. They are high mobility vehicles, usually based on continuous tracks carrying either a large howitzer, field gun, a mortar or some form of rocket or missile launcher. They are usually used for long-range indirect bombardment support on the battlefield., A siege is a military blockade of a city or fortress with the intent of conquering by attrition or assault. This derives from "sedere", Latin for "to sit". Siege warfare is a form of constant, low-intensity conflict characterized by one party holding a strong, static defensive position. Consequently, an opportunity for negotiation between combatants is not uncommon, as proximity and fluctuating advantage can encourage diplomacy., 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., A siege engine is a device that is designed to break or circumvent city walls and other fortifications in siege warfare. Some have been operated close to the fortifications, while others have been used to attack from a distance. From antiquity, siege engines were constructed largely of wood and tended to use mechanical advantage to fling stones and similar missiles. With the development of gunpowder and improved metallurgical techniques, siege engines became artillery. Collectively, siege engines or artillery together with the necessary troops and transport vehicles to conduct a siege are referred to as a siege-train., In international arms control, small arms include revolvers and pistols, rifles and carbines, assault rifles, submachine guns and light machine guns. Together with light weapons (heavy machine guns; hand-held grenade launchers; portable anti-aircraft and anti-tank guns; recoilless rifles; portable launchers of anti-aircraft and anti-tank missile systems; and mortars of calibres of less than 100 mm), they comprise the Small Arms and Light Weapons (SALW) protocol., Field artillery is a category of mobile artillery used to support armies in the field . These weapons are specialized for mobility , tactical proficiency , long range , short range and extremely long range target engagement . Until the early 20th century , field artillery were also known as foot artillery , for while the guns were pulled by beasts of burden ( often horses ) , the gun crews would usually march on foot , thus providing fire support mainly to the infantry . This was in contrast to horse artillery , whose emphasis on speed while supporting cavalry units necessitated lighter guns and crews riding on horseback . Whereas horse artillery has been superseded by self - propelled artillery , field artillery has survived to this day both in name and mission , albeit with motor vehicles towing the guns , carrying the crews and transporting the ammunition . Modern artillery has also advanced to rapidly deployable wheeled and tracked vehicles and precision delivered munitions capable of striking targets at ranges between 15 and 300 kilometers ., Subject: field artillery, Relation: has_part, Options: (A) a (B) artillery (C) engine (D) field (E) field gun (F) infantry (G) infantry corps (H) light (I) one (J) system (K) technology (L) train
