PROBLEM: Context: Friedrich Engels (or  28 November 1820  5 August 1895) was a German philosopher, social scientist, journalist, and businessman. He founded Marxist theory together with Karl Marx. In 1845, he published "The Condition of the Working Class in England", based on personal observations and research in Manchester., A journalist is a person who collects, writes, or distributes news or other current information. A journalist's work is called journalism. A journalist can work with general issues or specialize in certain issues. However, most journalists tend to specialize, and by cooperating with other journalists, produce journals that span many topics. For example, a sports journalist covers news within the world of sports, but this journalist may be a part of a newspaper that covers many different topics., Jean - Laurent - Frederick Longuet ( 1876 -- 1938 ) was a French socialist and Karl Marx 's grandson . Son of Charles and Jenny Longuet . French lawyer and Socialist who in the First World War and founder and editor of the newspaper Le Populaire . He was a pacifist , but also supported war credits during the course of the First World War . At the Strasbourg Congress in 1918 his policy was adopted by the majority of the French Section of the Workers ' International ( SFIO ) socialist party . After the Tours Congress of 1920 where the Communists gained the majority he supported the minority and joined the centrist Two - and - a - half International ( the Vienna Union ) . He criticized the League Against Imperialism created in 1927 and supported by the Comintern . Longuet supported pro-Zionist positions at the Socialist International meeting in Brussels in 1930 and at a speech to a Zionist group in Paris in 1935 ., A pamphlet is an unbound booklet (that is, without a hard cover or binding). It may consist of a single sheet of paper that is printed on both sides and folded in half, in thirds, or in fourths, called a "leaflet", or it may consist of a few pages that are folded in half and saddle stapled at the crease to make a simple book., The Communist Manifesto (originally Manifesto of the Communist Party) is an 1848 political pamphlet by German philosophers Karl Marx and Friedrich Engels. Commissioned by the Communist League and originally published in London (in German as "Manifest der Kommunistischen Partei") just as the revolutions of 1848 began to erupt, the "Manifesto" was later recognised as one of the world's most influential political manuscripts. It presents an analytical approach to the class struggle (historical and then-present) and the problems of capitalism and the capitalist mode of production, rather than a prediction of communism's potential future forms., An economist is a practitioner in the social science discipline of economics., Trier, formerly known in English as Treves, is a city in Germany on the banks of the Moselle. Trier lies in a valley between low vine-covered hills of red sandstone in the west of the state of Rhineland-Palatinate, near the border with Luxembourg and within the important Moselle wine region., Karl Marx (5 May 1818  14 March 1883) was a German-born scientist, philosopher, economist, sociologist, journalist, and revolutionary socialist. Born in Trier to a middle-class family, he later studied political economy and Hegelian philosophy. As an adult, Marx became stateless and spent much of his life in London, England, where he continued to develop his thought in collaboration with German thinker Friedrich Engels and published various works, the most well-known being the 1848 pamphlet "The Communist Manifesto". His work has since influenced subsequent intellectual, economic, and political history., A philosopher is someone who practices philosophy, which involves rational inquiry into areas that are outside of either theology or science. The term "philosopher" comes from the Ancient Greek ("philosophos") meaning "lover of wisdom". The coining of the term has been attributed to the Greek thinker Pythagoras (6th century BC)., Political economy is a term used for studying production and trade, and their relations with law, custom, and government, as well as with the distribution of national income and wealth. "Political economy" originated in moral philosophy. It was developed in the 18th century as the study of the economies of states, or "polities", hence the term "political" economy., Subject: jean longuet, Relation: place_of_birth, Options: (A) engels (B) england (C) german (D) germany (E) hard (F) london (G) manchester (H) march (I) most (J) of (K) trier

PROBLEM: Context: An anode is an electrode through which conventional current flows into a polarized electrical device. A common mnemonic is ACID for "anode current into device". The direction of (positive) electric current is opposite to the direction of electron flow: (negatively charged) electrons flow out the anode to the outside circuit., An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). The word was coined by William Whewell at the request of the scientist Michael Faraday from the Greek words "elektron", meaning amber (from which the word electricity is derived), and "hodos", a way., Semiconductors are crystalline or amorphous solids with distinct electrical characteristics. They are of high electrical resistance   higher than typical resistance materials, but still of much lower resistance than insulators. Their resistance decreases as their temperature increases, which is behavior opposite to that of a metal. Finally, their conducting properties may be altered in useful ways by the deliberate, controlled introduction of impurities ("doping") into the crystal structure, which lowers its resistance but also permits the creation of semiconductor junctions between differently-doped regions of the extrinsic semiconductor crystal. The behavior of charge carriers which include electrons, ions and electron holes at these junctions is the basis of diodes, transistors and all modern electronics., Silicon is a chemical element with symbol Si and atomic number 14. A hard and brittle crystalline solid with a blue-gray metallic luster, it is a tetravalent metalloid. It is a member of group 14 in the periodic table, along with carbon above it and germanium, tin, lead, and flerovium below. It is rather unreactive, though less so than germanium, and has great chemical affinity for oxygen; as such, it was first prepared and characterized in pure form only in 1823 by Jöns Jakob Berzelius., Electronics is the science of controlling electrical energy electrically, in which the electrons have a fundamental role. Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes, integrated circuits, associated passive electrical components, and interconnection technologies. Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit., Selenium is a chemical element with symbol Se and atomic number 34. It is a nonmetal with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium. It rarely occurs in its elemental state or as pure ore compounds in the Earth's crust. Selenium (Greek  "selene" meaning "Moon") was discovered in 1817 by Jöns Jacob Berzelius, who noted the similarity of the new element to the previously discovered tellurium (named for the Earth)., An intrinsic semiconductor, also called an undoped semiconductor or i-type semiconductor, is a pure semiconductor without any significant dopant species present. The number of charge carriers is therefore determined by the properties of the material itself instead of the amount of impurities. In intrinsic semiconductors the number of excited electrons and the number of holes are equal: n = p., Germanium is a chemical element with symbol Ge and atomic number 32. It is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. Pure germanium is a semiconductor with an appearance similar to elemental silicon. Like silicon, germanium naturally reacts and forms complexes with oxygen in nature. Unlike silicon, it is too reactive to be found naturally on Earth in the free (elemental) state., A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations. The scientific study of crystals and crystal formation is known as crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification., In electronics, a diode is a two-terminal electronic component that conducts primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance to the flow of current in one direction, and high (ideally infinite) resistance in the other. A semiconductor diode, the most common type today, is a crystalline piece of semiconductor material with a pn junction connected to two electrical terminals. A vacuum tube diode has two electrodes, a plate (anode) and a heated cathode. Semiconductor diodes were the first semiconductor electronic devices. The discovery of crystals' rectifying abilities was made by German physicist Ferdinand Braun in 1874. The first semiconductor diodes, called cat's whisker diodes, developed around 1906, were made of mineral crystals such as galena. Today, most diodes are made of silicon, but other semiconductors such as selenium or germanium are sometimes used., A pn junction is a boundary or interface between two types of semiconductor material, p-type and n-type, inside a single crystal of semiconductor. The "p" (positive) side contains an excess of holes, while the "n" (negative) side contains an excess of electrons. The p-n junction is created by doping, for example by ion implantation, diffusion of dopants, or by epitaxy (growing a layer of crystal doped with one type of dopant on top of a layer of crystal doped with another type of dopant). If two separate pieces of material were used, this would introduce a grain boundary between the semiconductors that would severely inhibit its utility by scattering the electrons and holes., Galena, also called lead glance, is the natural mineral form of lead(II) sulfide. It is the most important ore of lead and an important source of silver., Vacuum is space void of matter. The word stems from the Latin adjective "vacuus" for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a "perfect" vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is lower than atmospheric pressure. The Latin term in vacuo is used to describe an object that is surrounded by a vacuum., A dopant, also called a doping agent, is a trace impurity element that is inserted into a substance (in very low concentrations) to alter the electrical or optical properties of the substance. In the case of crystalline substances, the atoms of the dopant very commonly take the place of elements that were in the crystal lattice of the base material. The crystalline materials are frequently either crystals of a semiconductor such as silicon and germanium for use in solid-state electronics, or transparent crystals for use in the production of various laser types; however, in some cases of the latter, noncrystalline substances such as glass can also be doped with impurities., An electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form and are not to be confused with electrical elements, which are conceptual abstractions representing idealized electronic components., The electron is a subatomic particle, symbol or , with a negative elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron has a mass that is approximately 1/1836 that of the proton. Quantum mechanical properties of the electron include an intrinsic angular momentum (spin) of a half-integer value, expressed in units of the reduced Planck constant, "". As it is a fermion, no two electrons can occupy the same quantum state, in accordance with the Pauli exclusion principle. Like all matter, electrons have properties of both particles and waves: they can collide with other particles and can be diffracted like light. The wave properties of electrons are easier to observe with experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a larger De Broglie wavelength for a given energy., In physics, a charge carrier is a particle free to move, carrying an electric charge, especially the particles that carry electric charges in electrical conductors. Examples are electrons, ions and holes. In a conducting medium, an electric field can exert force on these free particles, causing a net motion of the particles through the medium; this is what constitutes an electric current. In different conducting media, different particles serve to carry charge:, In electronics, a vacuum tube, an electron tube, or just a tube (North America), or valve (Britain and some other regions), is a device that controls electric current between electrodes in an evacuated container.
Vacuum tubes mostly rely on thermionic emission of electrons from a hot filament or a cathode heated by the filament. This type is called a thermionic tube or thermionic valve. A phototube, however, achieves electron emission through the photoelectric effect. Not all electronic circuit valves/electron tubes are vacuum tubes (evacuated); gas-filled tubes are similar devices containing a gas, typically at low pressure, which exploit phenomena related to electric discharge in gases, usually without a heater., A cathode is the electrode from which a conventional current leaves a polarized electrical device. (This definition can be recalled by using the mnemonic "CCD" for "cathode current departs".) A conventional current describes the direction in which positive electronic charges move. Electrons have a negative charge, so the movement of electrons is opposite to the conventional current flow. Consequently, the mnemonic "cathode current departs" also means that electrons flow into the device's cathode., A PIN diode is a diode with a wide , undoped intrinsic semiconductor region between a p - type semiconductor and an n - type semiconductor region . The p - type and n - type regions are typically heavily doped because they are used for ohmic contacts . The wide intrinsic region is in contrast to an ordinary PN diode . The wide intrinsic region makes the PIN diode an inferior rectifier ( one typical function of a diode ) , but it makes the PIN diode suitable for attenuators , fast switches , photodetectors , and high voltage power electronics applications ., Subject: pin diode, Relation: instance_of, Options: (A) approximation (B) base (C) behavior (D) case (E) charge (F) chemical (G) chemical element (H) component (I) conductor (J) constant (K) crystal (L) diode (M) direction (N) electric current (O) electrode (P) electron (Q) electronic circuit (R) electronic component (S) electronics (T) force (U) formation (V) generation (W) group (X) interface (Y) junction (Z) laboratory ([) laser (\) mass (]) material (^) member (_) metal (`) mineral (a) mnemonic (b) motion (c) negative (d) ore (e) part (f) particle (g) physics (h) principle (i) process (j) role (k) semiconductor (l) semiconductor diode (m) side (n) single (o) space (p) state (q) structure (r) study (s) symbol (t) system (u) temperature (v) test (w) word

PROBLEM: Context: The Vancouver Canucks are a professional ice hockey team based in Vancouver, :British Columbia. They are members of the Pacific Division of the Western Conference of the National Hockey League (NHL). The Canucks play their home games at Rogers Arena, formerly known as General Motors Place, which has an official capacity of 18,860. Henrik Sedin is currently the captain of the team, Willie Desjardins is the head coach and Jim Benning is the general manager., The Tampa Bay Lightning is a professional ice hockey team based in Tampa, Florida. It is a member of the Atlantic Division of the Eastern Conference of the National Hockey League (NHL). Tampa Bay has one Stanley Cup championship in their history, in 200304. The team is often referred to as the Bolts, and the nickname is used on the current third jersey. The Lightning plays home games in the Amalie Arena in Tampa., In ice hockey, the goaltender is the player responsible for preventing the hockey puck from entering their team's net, thus preventing the opposing team from scoring. The goaltender usually plays in or near the area in front of the net called the "goal crease" (often referred to simply as " the crease" or "the net"). Goaltenders tend to stay at or beyond the top of the crease to cut down on the angle of shots. In today's age of goaltending there are two common styles, butterfly and hybrid (hybrid is a mix of the traditional stand-up style and butterfly technique). Because of the power of shots, the goaltender wears special equipment designed to protect the body from direct impact. The goalie is one of the most valuable players on the ice, as their performance can greatly change the outcome or score of the game. One-on-one situations, such as breakaways and shootouts, have the tendency to highlight a goaltender's pure skill, or lack thereof. Only one goaltender is allowed to be on the ice for each team at any given time., The Chicago Blackhawks (spelled Black Hawks until 1986, and known colloquially as the Hawks) are a professional ice hockey team based in Chicago, Illinois. They are members of the Central Division of the Western Conference of the National Hockey League (NHL). They have won six Stanley Cup championships since their founding in 1926. The Blackhawks are one of the "Original Six" NHL teams along with the Detroit Red Wings, Montreal Canadiens, Toronto Maple Leafs, Boston Bruins and New York Rangers. Since , the club's home rink is the United Center. The club had previously played for 65 years at Chicago Stadium., The City of New York, often called New York City or simply New York, is the most populous city in the United States. With an estimated 2015 population of 8,550,405 distributed over a land area of just , New York City is also the most densely populated major city in the United States. Located at the southern tip of the state of New York, the city is the center of the New York metropolitan area, one of the most populous urban agglomerations in the world. A global power city, New York City exerts a significant impact upon commerce, finance, media, art, fashion, research, technology, education, and entertainment, its fast pace defining the term "New York minute". Home to the headquarters of the United Nations, New York is an important center for international diplomacy and has been described as the cultural and financial capital of the world., Ice hockey is a contact team sport played on ice, usually in a rink, in which two teams of skaters use their sticks to shoot a vulcanized rubber puck into their opponent's net to score points. Ice hockey teams usually consist of six players each: one goaltender, and five players who skate up and down the ice trying to take the puck and score a goal against the opposing team., The National Hockey League (NHL) is a professional ice hockey league currently composed of 31 member clubs. Of the 30 clubs currently playing, 23 are in the United States and 7 in Canada. Headquartered in New York City, the NHL is considered to be the premier professional ice hockey league in the world, and one of the major professional sports leagues in the United States and Canada. The Stanley Cup, the oldest professional sports trophy in North America, is awarded annually to the league playoff champion at the end of each season., Ronald T. Sutter ( born December 2 , 1963 ) is a retired Canadian professional ice hockey player . He is the brother of Brian , Brent , Darryl , Duane and Rich Sutter , all of whom played in the National Hockey League ( NHL ) . He is the twin brother of Rich and was the last Sutter brother to retire from the NHL ., Richard G. Sutter (born December 2, 1963) is a Canadian retired professional ice hockey right winger who played 13 seasons in the National Hockey League (NHL) for the Pittsburgh Penguins, Philadelphia Flyers, Vancouver Canucks, St. Louis Blues, Chicago Blackhawks, Toronto Maple Leafs and Tampa Bay Lightning. He is part of the Sutter family, the family that sent 6 brothers to the NHL. He is the twin brother of Ron Sutter., The major professional sports leagues in the United States and Canada are the highest professional competitions of team sports in the United States and Canada. The four leagues universally included in the definition are Major League Baseball (MLB), the National Basketball Association (NBA), the National Football League (NFL), and the National Hockey League (NHL). Other prominent leagues include Major League Soccer (MLS) and the Canadian Football League (CFL)., The Pittsburgh Penguins are a professional ice hockey team based in Pittsburgh, Pennsylvania. They are members of the Metropolitan Division of the Eastern Conference of the National Hockey League (NHL). The franchise was founded in 1967 as one of the first expansion teams during the league's original expansion from six to twelve teams. The Penguins played in the Civic Arena, also known to Pittsburgh fans as "The Igloo", from the time of their inception through the end of the 200910 season. They moved into their new arena, PPG Paints Arena, to begin the 201011 NHL season. They have qualified for five Stanley Cup Finals, winning the Stanley Cup four times  in 1991, 1992, 2009, and 2016., The Sutter family, originally from Viking, Alberta, Canada, are one of the most famous families in the National Hockey League (NHL). Six brothers: Brent, Brian, Darryl, Duane, Rich and Ron, reached the NHL in the late 70s and early 80s. Four brothers, Brian, Duane, Darryl and Brent, have gone on to become coaches and general managers as well. All brothers played either for the Chicago Blackhawks or the St. Louis Blues at one point or another. A seventh brother named Gary is said by his brothers to have been the best hockey player of all seven boys. Rather than making his living as a hockey player, Gary stayed home to work on the family farm, as Rich remarked on an episode of the Canadian sports show "Off the Record"., The Toronto Maple Leafs (officially the Toronto Maple Leaf Hockey Club) are a professional ice hockey team based in Toronto, Ontario. They are members of the Atlantic Division of the Eastern Conference of the National Hockey League (NHL). The team is one of the "Original Six" league members. They are owned by Maple Leaf Sports & Entertainment, Ltd. and are represented by Chairman Larry Tanenbaum. In February 1999, they moved to the Air Canada Centre, which replaced Maple Leaf Gardens, the team's home since 1931., The Philadelphia Flyers are a professional ice hockey team based in Philadelphia, Pennsylvania. They are members of the Metropolitan Division of the Eastern Conference of the National Hockey League (NHL). Part of the 1967 NHL Expansion, the Flyers were the first expansion team in the post-Original Six era to win the Stanley Cup, victorious in 197374 and again in 197475., The Stanley Cup is the championship trophy awarded annually to the National Hockey League (NHL) playoff winner. Originally commissioned in 1892 as the "Dominion Hockey Challenge Cup", the trophy is named for Lord Stanley of Preston, thenGovernor General of Canada, who awarded it to Canada's top-ranking amateur ice hockey club, which the entire Stanley family supported, with the sons and daughters playing and promoting the game. The first Cup was awarded in 1893 to Montreal HC, and subsequent winners from 1893 to 1914 were determined by challenge games and league play. Professional teams first became eligible to challenge for the Stanley Cup in 1906. In 1915, the two professional ice hockey organizations, the National Hockey Association (NHA) and the Pacific Coast Hockey Association (PCHA), reached a gentlemen's agreement in which their respective champions would face each other annually for the Stanley Cup. After a series of league mergers and folds, it was established as the "de facto" championship trophy of the NHL in 1926 and then the "de jure" NHL championship prize in 1947., A team sport includes any sport which involves two or more players working together towards a shared objective. A team sport is an activity in which individuals are organized into opposing teams which compete to win. Examples are basketball, volleyball, water polo, handball, lacrosse, cricket, baseball, and the various forms of football and hockey., Ice is water frozen into a solid state. Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color., Subject: ron sutter, Relation: place_of_birth, Options: (A) alberta (B) british columbia (C) canada (D) canadian (E) center (F) centre (G) chicago (H) commerce (I) home (J) illinois (K) jersey (L) maple (M) new york (N) new york city (O) of (P) pennsylvania (Q) philadelphia (R) pittsburgh (S) polo (T) puck (U) stanley (V) tampa bay (W) toronto (X) vancouver (Y) viking (Z) winger ([) york
