Q: Context: Tonga (or ; Tongan: "Puleanga Fakatui o Tonga"), officially the Kingdom of Tonga, is a Polynesian sovereign state and archipelago comprising 169 islands of which 36 are inhabited. The total surface area is about scattered over of the southern Pacific Ocean. It has a population of 103,000 people of whom 70% reside on the main island of Tongatapu., A prime minister is the most senior minister of cabinet in the executive branch of government, often in a parliamentary or semi-presidential system. In many systems, the prime minister selects and may dismiss other members of the cabinet, and allocates posts to members within the government. In most systems, the prime minister is the presiding member and chairman of the cabinet. In a minority of systems, notably in semi-presidential systems of government, a prime minister is the official who is appointed to manage the civil service and execute the directives of the head of state.
In parliamentary systems fashioned after the Westminster system, the prime minister is the presiding and actual head of government and head of the executive branch. In such systems, the head of state or the head of state's official representative (i.e. the monarch, president, or governor-general) usually holds a largely ceremonial position, although often with reserve powers., This is a list of Prime Ministers ( until 1970 , Premiers ) of Tonga from the establishment of that office in 1876 until the present day ., Tongatapu is the main island of the Kingdom of Tonga and the location of its capital Nukualofa. It is located in Tonga's southern island group, to which it gives its name, and is the country's most populous island, with approximately 71,260 residents (2006), 70.5% of the national population, on . Its maximum height is . Tongatapu is Tonga's centre of government and the seat of its monarchy., An archipelago, sometimes called an island group or island chain, is a chain, cluster or collection of islands. The word "archipelago" is derived from the Greek "- arkhi-" ("chief") and " pelagos" ("sea") through the Italian "arcipelago". In Italian, possibly following a tradition of antiquity, the Archipelago (from medieval Greek "*" and Latin "archipelagus") was the proper name for the Aegean Sea and, later, usage shifted to refer to the Aegean Islands (since the sea is remarkable for its large number of islands). It is now used to refer to any island group or, sometimes, to a sea containing a small number of scattered islands., 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., Polynesia ( from "poly" "many" + "nsos" "island") is a subregion of Oceania, made up of over 1,000 islands scattered over the central and southern Pacific Ocean. The indigenous people who inhabit the islands of Polynesia are termed Polynesians and they share many similar traits including language family, culture, and beliefs. Historically, they were experienced sailors and used stars to navigate during the night., Subject: prime minister of tonga, Relation: instance_of, Options: (A) 1 (B) archipelago (C) area (D) capital (E) chain (F) cluster (G) collection (H) family (I) government (J) island (K) location (L) name (M) number (N) ocean (O) position (P) sea (Q) share (R) sovereign state (S) state (T) subregion (U) surface (V) tradition (W) word

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. The Appalachian Mountains run through its middle. The commonwealth borders Delaware to the southeast, Maryland to the south, West Virginia to the southwest, Ohio to the west, Lake Erie and the Canadian province of Ontario to the northwest, New York to the north, and New Jersey to the east., Ohio is an Eastern state in the Great Lakes region of the United States. Ohio is the 34th largest by area, the 7th most populous, and the 10th most densely populated of the 50 United States. The state's capital and largest city is Columbus., A postal code (also known locally in various English-speaking countries throughout the world as a postcode, post code, Eircode, PIN Code or ZIP Code ) is a series of letters and/or digits, sometimes including spaces or punctuation, included in a postal address for the purpose of sorting mail., New Jersey is a state in the Northeastern United States and mid-Atlantic regions of the United States. It is bordered on the north and east by New York, on the southeast and south by the Atlantic Ocean, on the west by Pennsylvania, and on the southwest by Delaware. New Jersey is the fourth-smallest state but the 11th-most populous and the most densely populated of the 50 United States. New Jersey lies entirely within the combined statistical areas of New York City and Philadelphia and is the third-wealthiest U.S. state by per capita income as of 2014., Delaware is a state located in the Mid-Atlantic and/or Northeastern regions of the United States. It is bordered to the south and west by Maryland, to the northeast by New Jersey, and to the north by Pennsylvania. The state takes its name from Thomas West, 3rd Baron De La Warr, an English nobleman and Virginia's first colonial governor., West Virginia is a state located in the Appalachian region of the Southern United States. It is bordered by Virginia to the southeast, Kentucky to the southwest, Ohio to the northwest, Pennsylvania to the north (and, slightly, east), and Maryland to the northeast. West Virginia is the 41st largest by area, the 38th most populous, and has the second lowest household income of the 50 United States. The capital and largest city is Charleston., This list of current cities , towns , unincorporated communities , counties , and other recognized places in the U.S. state of Pennsylvania also includes information on the number and names of counties in which the place lies , and its lower and upper zip code bounds , if applicable ., Ontario, one of the 13 provinces and territories of Canada, is located in east-central Canada. It is Canada's most populous province by a large margin, accounting for nearly 40 percent of all Canadians, and is the second-largest province in total area. Ontario is fourth-largest in total area when the territories of the Northwest Territories and Nunavut are included. 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

Q: Context: In the context of spaceflight, a satellite is an artificial object which has been intentionally placed into orbit. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as Earth's Moon., A rocket (from Italian "rocchetto" "bobbin") is a missile, spacecraft, aircraft or other vehicle that obtains thrust from a rocket engine. Rocket engine exhaust is formed entirely from propellant carried within the rocket before use. Rocket engines work by action and reaction and push rockets forward simply by expelling their exhaust in the opposite direction at high speed, and can therefore work in the vacuum of space., The Douglas DC - 8 ( also known as the McDonnell Douglas DC - 8 ) is a four - engine long - range narrow - body jet airliner built from 1958 to 1972 by the Douglas Aircraft Company . Launched after the competing Boeing 707 , the DC - 8 nevertheless kept Douglas in a strong position in the airliner market , and remained in production until 1972 when it began to be superseded by larger wide - body designs , including the Boeing 747 , McDonnell Douglas DC - 10 and Lockheed L - 1011 TriStar . The DC - 8 's design allowed it a slightly larger cargo capacity than the 707 and some re-engined DC - 8s are still in use as freighters ., An airliner is a type of aircraft for transporting passengers and air cargo. Such aircraft are most often operated by airlines. Although the definition of an airliner can vary from country to country, an airliner is typically defined as an aircraft intended for carrying multiple passengers or cargo in commercial service., Boeing Commercial Airplanes (BCA) is a division of The Boeing Company. It designs, assembles, markets, and sells jet airliners and business jets (Boeing Business Jets); it also provides product-related maintenance and training to customers worldwide. It operates from division headquarters in Renton, Washington, with more than a dozen engineering, manufacturing, and assembly facilities located throughout the U.S. and internationally. BCA includes the assets of the Douglas Aircraft division of the former McDonnell Douglas Corporation, which merged with Boeing in 1997. The current President and CEO of Boeing Commercial Airplanes is Raymond Conner, the former head of Sales, Marketing and Services., The fuselage (from the French "fusele" "spindle-shaped") is an aircraft's main body section that holds crew and passengers or cargo. In single-engine aircraft it will usually contain an engine, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage which in turn is used as a floating hull. The fuselage also serves to position control and stabilization surfaces in specific relationships to lifting surfaces, required for aircraft stability and maneuverability., A jet engine is a reaction engine discharging a fast-moving jet that generates thrust by jet propulsion. This broad definition includes airbreathing jet engine(turbojets, turbofans, ramjets, and pulse jets) and non-airbreathing jet engines (such as rocket engines). In general, jet engines are combustion engines., An S-duct (or "serpentine inlet") is a type of jet engine intake duct used in several types of trijet aircraft. In this configuration, the intake is in the upper rear center of the aircraft, above or below the stabilizer, while the exhaust and engine is at the rear of the aircraft. The S-duct is located in the tail, or empennage, of the aircraft. The shape of the S-duct is distinctive and easily recognized, and was used in several aircraft, beginning in 1962 with the Hawker Siddeley Trident. Currently, the Dassault Falcon 7X and Dassault Falcon 900 business jets, and the Tupolev Tu-154M narrow-body airliner in limited production, are the only aircraft in production that use the S-duct design., The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the "turbo" portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the "fan", a ducted fan that uses the mechanical energy from the gas turbine to accelerate air rearwards. Thus, whereas all the air taken in by a turbojet passes through the turbine (through the combustion chamber), in a turbofan some of that air bypasses the turbine. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of those contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core compared to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working in concert; engines that use more jet thrust relative to fan thrust are known as "low-bypass turbofans", conversely those that have considerably more fan thrust than jet thrust are known as "high-bypass". Most commercial aviation jet engines in use today are of the high-bypass type, and most modern military fighter engines are low-bypass. Afterburners are not used on high-bypass turbofan engines but may be used on either low-bypass turbofan or turbojet engines., A cargo aircraft (also known as freight aircraft, freighter, airlifter or cargo jet) is a fixed-wing aircraft that is designed or converted for the carriage of cargo rather than passengers. Such aircraft usually do not incorporate passenger amenities and generally feature one or more large doors for loading cargo. Freighters may be operated by civil passenger or cargo airlines, by private individuals or by the armed forces of individual countries (for the last see military transport aircraft).
Aircraft designed for cargo flight usually have features that distinguish them from conventional passenger aircraft: a wide/tall fuselage cross-section, a high-wing to allow the cargo area to sit near the ground, a large number of wheels to allow it to land at unprepared locations, and a high-mounted tail to allow cargo to be driven directly into and off the aircraft., The Lockheed L-1011 TriStar, commonly referred to as the L-1011 (pronounced "L-ten-eleven") or TriStar, is a medium-to-long-range, wide-body trijet airliner by Lockheed Corporation. It was the third wide-body airliner to enter commercial operations, after the Boeing 747 and the McDonnell Douglas DC-10. The airliner has a seating capacity up to 400 passengers and a range over . Its trijet configuration has three Rolls-Royce RB211 engines with one engine under each wing, and a third engine, center-mounted with an S-duct air inlet embedded in the tail and the upper fuselage. The aircraft has an autoland capability, an automated descent control system, and available lower deck galley and lounge facilities., An aerospace manufacturer is a company or individual involved in the various aspects of designing, building, testing, selling, and maintaining aircraft, aircraft parts, missiles, rockets, and/or spacecraft. Aerospace is a high technology industry., The McDonnell Douglas DC-10 is a three-engine wide-body jet airliner manufactured by McDonnell Douglas. The DC-10 has range for medium- to long-haul flights, capable of carrying a maximum of 380 passengers. Its most distinguishing feature is the two turbofan engines mounted on underwing pylons and a third engine at the base of the vertical stabilizer. The model was a successor to McDonnell Douglas's DC-8 for long-range operations, and competed in the same markets as the Lockheed L-1011 TriStar, which has a similar layout. In its early years the DC-10 had a poor safety record; however, this has greatly improved over time., A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by jet engines (jet propulsion)., McDonnell Douglas was a major American aerospace manufacturing corporation and defense contractor formed by the merger of McDonnell Aircraft and the Douglas Aircraft Company in 1967. Between then and its own merger with Boeing in 1997, it produced a number of well-known commercial and military aircraft such as the DC-10 airliner and F-15 Eagle air-superiority fighter., The Boeing 747 is an American wide-body commercial jet airliner and cargo aircraft, often referred to by its original nickname, "Jumbo Jet", or "Queen of the Skies". Its distinctive "hump" upper deck along the forward part of the aircraft makes it among the world's most recognizable aircraft, and it was the first wide-body produced. Manufactured by Boeing's Commercial Airplane unit in the United States, the original version of the 747 was envisioned to have 150 percent greater capacity than the Boeing 707, one of the common large commercial aircraft of the 1960s. First flown commercially in 1970, the 747 held the passenger capacity record for 37 years. , the 747 has been involved in 60 hull-loss accidents resulting in 3,718 fatalities., An airplane or aeroplane (informally plane) is a powered, fixed-wing aircraft that is propelled forward by thrust from a jet engine or propeller. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research. Commercial aviation is a massive industry involving the flying of tens of thousands of passengers daily on airliners. Most airplanes are flown by a pilot on board the aircraft, but some are designed to be remotely or computer-controlled., The Boeing Company is an American multinational corporation that designs, manufactures, and sells airplanes, rotorcraft, rockets, and satellites worldwide. The company also provides leasing and product support services. Boeing is among the largest global aircraft manufacturers; it is the second-largest defense contractor in the world based on 2015 revenue, and is the largest exporter in the United States by dollar value. Boeing stock is a component of the Dow Jones Industrial Average., A trijet is a jet aircraft powered by three jet engines. Early twinjet designs were limited by the FAA's 60-minute rule, whereby the flight path of twin-engine jetliners was restricted to within 60 minutes' flying time from a suitable airport, in case of engine failure. In 1964, this rule was lifted for trijet designs, as they had a greater safety margin. This led to a flurry of trijet designs, which in their heyday of the 1980s were the most popular airliner configuration. However, subsequent improvements in engine reliability and a corresponding relaxation in airline safety rules made the trijet obsolete for normal passenger services, and no manufacturer now produces three-engine airliners., A multinational corporation"" or worldwide Enterprise is a corporate organization that owns or controls production of goods or services in one or more countries other than their home country. It can also be referred as an international corporation, a transnational corporation, or a stateless corporation., The Dow Jones Industrial Average , also called DJIA, the Industrial Average, the Dow Jones, the Dow Jones Industrial, ^DJI, the Dow 30 or simply the Dow, is a stock market index, and one of several indices created by "Wall Street Journal" editor and Dow Jones & Company co-founder Charles Dow. The industrial average was first calculated on May 26, 1896. Currently owned by S&P Dow Jones Indices, which is majority owned by S&P Global, it is the most notable of the Dow Averages, of which the first (non-industrial) was first published on February 16, 1885. The averages are named after Dow and one of his business associates, statistician Edward Jones. It is an index that shows how 30 large publicly owned companies based in the United States have traded during a standard trading session in the stock market. It is the second-oldest U.S. market index after the Dow Jones Transportation Average, which was also created by Dow.
The "Industrial" portion of the name is largely historical, as many of the modern 30 components have little or nothing to do with traditional heavy industry. The average is price-weighted, and to compensate for the effects of stock splits and other adjustments, it is currently a scaled average. The value of the Dow is not the actual average of the prices of its component stocks, but rather the sum of the component prices divided by a divisor, which changes whenever one of the component stocks has a stock split or stock dividend, so as to generate a consistent value for the index. Since the divisor is currently less than one, the value of the index is larger than the sum of the component prices. Although the Dow is compiled to gauge the performance of the industrial sector within the American economy, the index's performance continues to be influenced by not only corporate and economic reports, but also by domestic and foreign political events such as war and terrorism, as well as by natural disasters that could potentially lead to economic harm., The Boeing 707 is a mid-sized, long-range, narrow-body, four-engine jet airliner built by Boeing Commercial Airplanes from 1958 to 1979. Its name is commonly pronounced as "seven oh seven". Versions of the aircraft have a capacity from 140 to 219 passengers and a range of ., A jet airliner (or "jetliner", or "jet") is an airliner powered by jet engines (passenger jet aircraft). Airliners usually have two or four jet engines; three-engined designs were popular in the 1970s but are less common today., The Douglas Aircraft Company was an American aerospace manufacturer based in Southern California. It was founded in 1921 by Donald Wills Douglas, Sr. and later merged with McDonnell Aircraft in 1967 to form McDonnell Douglas. Douglas Aircraft Company largely operated as a division of McDonnell Douglas (MD) after the merger. MD later merged with Boeing in 1997., A rotorcraft or rotary-wing aircraft is a heavier-than-air flying machine that uses lift generated by wings, called rotary wings or rotor blades, that revolve around a mast. Several rotor blades mounted on a single mast are referred to as a rotor. The International Civil Aviation Organization (ICAO) defines a rotorcraft as "supported in flight by the reactions of the air on one or more rotors". Rotorcraft generally include those aircraft where one or more rotors are required to provide lift throughout the entire flight, such as helicopters, cyclocopters, autogyros, and gyrodynes. Compound rotorcraft may also include additional thrust engines or propellers and static lifting surfaces., The McDonnell Aircraft Corporation was an American aerospace manufacturer based in St. Louis, Missouri. The company was founded on July 6, 1939 by James Smith McDonnell, and was best known for its military fighters, including the F-4 Phantom II, and manned spacecraft including the Mercury capsule and Gemini capsule. McDonnell Aircraft later merged with the Douglas Aircraft Company to form McDonnell Douglas in 1967., In aviation, autoland describes a system that fully automates the landing procedure of an aircraft's flight, with the flight crew supervising the process. Such systems enable aircraft to land in weather conditions that would otherwise be dangerous or impossible to operate in., Subject: douglas dc-8, Relation: use, Options: (A) aviation (B) civil aviation (C) combustion (D) commercial aviation (E) engine (F) engineering (G) fighter (H) home (I) industry (J) landing (K) military (L) production (M) propulsion (N) research (O) safety (P) service (Q) spaceflight (R) training (S) transport (T) vehicle (U) war
