Q: Context: The European Union (EU) is a political and economic union of member states that are located primarily in Europe. It has an area of , and an estimated population of over 510 million. The EU has developed an internal single market through a standardised system of laws that apply in all member states. EU policies aim to ensure the free movement of people, goods, services, and capital within the internal market, enact legislation in justice and home affairs, and maintain common policies on trade, agriculture, fisheries, and regional development. Within the Schengen Area, passport controls have been abolished. A monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency., A republic (from ) is a sovereign state, country, or government which is organized with a form of government in which power resides in elected individuals representing the citizen body and government leaders exercise power according to the rule of law. In modern times, the definition of a republic commonly refers to a government which excludes a monarch. Currently, 147 of the world's 206 sovereign states use the word "republic" as part of their official names; not all of these are republics in the sense of having elected governments, nor do all nations with elected governments use the word "republic" in their names., Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries., Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe. It includes 16 constituent states, covers an area of , and has a largely temperate seasonal climate.

The city is situated on the river Elbe., Berlin is the capital and the largest city of Germany as well as one of its constituent 16 states. With a population of approximately 3.5 million people, Berlin is the second most populous city proper and the seventh most populous urban area in the European Union. Located in northeastern Germany on the banks of rivers Spree and Havel, it is the centre of the Berlin-Brandenburg Metropolitan Region, which has about 6 million residents from more than 180 nations. Due to its location in the European Plain, Berlin is influenced by a temperate seasonal climate. Around one-third of the city's area is composed of forests, parks, gardens, rivers and lakes., A parliamentary republic is a republic that operates under a parliamentary system of government where the executive branch (the government) derives its legitimacy from and is accountable to the legislature (the parliament). There are a number of variations of parliamentary republics. Most have a clear differentiation between the head of government and the head of state, with the head of government holding real power, much like constitutional monarchies. Some have combined the roles of head of state and head of government, much like presidential systems, but with a dependency upon parliamentary power., Düsseldorf (Low Franconian, Ripuarian: "Düsseldörp" ) is the capital city of the German state of North Rhine-Westphalia and the seventh most populous city in Germany. Düsseldorf is an international business and financial centre, renowned for its fashion and trade fairs. The city is headquarters to one Fortune Global 500 and two DAX companies. Messe Düsseldorf organises nearly one fifth of premier trade shows., Thom Barron ( born March 27 , 1971 , in Germany ) , is the stage name of a gay pornographic film actor ; he is considered to be Germany 's best - known international gay pornographic film actor ., Munich (also in British English ) is the capital and largest city of the German state of Bavaria, on the banks of River Isar north of the Bavarian Alps. Munich is the third largest city in Germany, after Berlin and Hamburg, and the 12th biggest city of the European Union, with a population of above 1.5 million. The Munich Metropolitan Region is home to 5.8 million people., The euro (sign: €; code: EUR) is the official currency of the eurozone, which consists of 19 of the member states of the European Union: Austria, Belgium, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Slovakia, Slovenia, and Spain. The currency is also officially used by the institutions of the European Union and four other European countries, as well as unilaterally by two others, and is consequently used daily by some 337 million Europeans . Outside of Europe, a number of overseas territories of EU members also use the euro as their currency., Frankfurt am Main is a metropolis and the largest city in the German state of Hesse and the fifth-largest city in Germany, with a 2015 population of 731,095 within its administrative boundaries, and 2.3 million in its urban area. The city is at the centre of the larger Frankfurt Rhine-Main Metropolitan Region, which has a population of 5.8 million and is Germany's second-largest metropolitan region after Rhine-Ruhr. Since the enlargement of the European Union in 2013, the geographic centre of the EU is about to the east of Frankfurt's CBD, the Bankenviertel. Frankfurt is culturally and ethnically diverse, with around half of the population, and a majority of young people, having a migration background. A quarter of the population are foreign nationals, including many expatriates., Cologne is the largest city in the German federal State of North Rhine-Westphalia and the fourth-largest city in Germany (after Berlin, Hamburg, and Munich). It is located within the Rhine-Ruhr metropolitan region, one of the major European metropolitan regions and the largest in Germany, with more than ten million inhabitants., Stuttgart ( Swabian: "Schduagert"), often nicknamed the ""Schwabenmetropole"" in reference to its location in the center of Swabia and the local dialect spoken by some natives, is the capital and largest city of the German state of Baden-Württemberg. It is located on the Neckar river in a fertile valley locally known as the "Stuttgarter Kessel" an hour from the Swabian Jura and the Black Forest. Stuttgart's name comes from the Old High German word ""Stuogarten"," or "stud farm"  a reference to the city's founding in 950 AD as a stud farm. Stuttgarts urban area has a population of 623,738, and a further making it the sixth largest city in Germany, 2.7 million people live in the citys administrative region, and another 5.3 million people in its metropolitan area, making it the fourth largest metropolitan area in Germany., Subject: thom barron, Relation: place_of_birth, Options: (A) atlantic ocean (B) austria (C) baden (D) banks (E) berlin (F) capital city (G) caucasus (H) central (I) centre (J) cologne (K) cyprus (L) düsseldorf (M) estonia (N) eu (O) fertile (P) forest (Q) frankfurt am main (R) german (S) germany (T) hamburg (U) ireland (V) italy (W) jura (X) luxembourg (Y) malta (Z) most ([) munich (\) of (]) republic (^) ruhr (_) saxon (`) southeast (a) stuttgart (b) union (c) westphalia

The first Robert Capa Gold Medal was awarded in 1955 to Howard Sochurek., San Francisco (SF) (Spanish for Saint Francis) officially the City and County of San Francisco, is the cultural, commercial, and financial center of Northern California. It is the birthplace of the United Nations. Located at the north end of the San Francisco Peninsula, San Francisco is about in area, making it the smallest countyand the only consolidated city-countywithin the state of California. With a density of about 18,451 people per square mile (7,124 people per km), San Francisco is the most densely settled large city (population greater than 200,000) in California and the second-most densely populated major city in the United States after New York City. San Francisco is the fourth-most populous city in California, after Los Angeles, San Diego, and San Jose, and the 13th-most populous city in the United Stateswith a census-estimated 2015 population of 864,816. The city and its surrounding areas are known as the San Francisco Bay Area, and are a part of the larger OMB-designated San Jose-San Francisco-Oakland combined statistical area, the fifth most populous in the nation with an estimated population of 8.7 million., The councilmanager government form is one of two predominant forms of local government in the United States; the other common form of local government is the mayorcouncil government form, which characteristically occurs in large cities. Councilmanager government form also is used in county governments in the United States and the governing body in a county may be called a council, a commission, freeholders, aldermen, and such. The councilmanager form also is used for municipal government in Canada and in Ireland, among many other countries, both for city councils and county councils., Alameda (; Spanish: ) is a city in Alameda County, California, United States. It is located on Alameda Island and Bay Farm Island, and is adjacent to and south of Oakland and east of San Francisco across the San Francisco Bay. Bay Farm Island, a portion of which is also known as "Harbor Bay Isle", is not actually an island, and is part of the mainland adjacent to the Oakland International Airport. The city's estimated 2016 population was 79,277. Alameda is a charter city, rather than a general law city, allowing the city to provide for any form of government.

Q: Context: A gemstone (also called a gem, fine gem, jewel, precious stone or semi-precious stone) is a piece of mineral crystal which, in cut and polished form, is used to make jewelry or other adornments. However, certain rocks (such as lapis lazuli) or organic materials that are not minerals (such as amber, jet, and pearl) are also used for jewelry and are therefore often considered to be gemstones as well. Most gemstones are hard, but some soft minerals are used in jewelry because of their luster or other physical properties that have aesthetic value. Rarity is another characteristic that lends value to a gemstone. Apart from jewelry, from earliest antiquity engraved gems and hardstone carvings, such as cups, were major luxury art forms. A gem maker is called a lapidary or gemcutter; a diamond worker is a diamantaire., Garnets are a group of silicate minerals that have been used since the Bronze Age as gemstones and abrasives., The interdisciplinarity field of materials science, also commonly termed materials science and engineering, involves the discovery and design of new materials, with an emphasis on solids. The intellectual origins of materials science stem from the Enlightenment, when researchers began to use analytical thinking from chemistry, physics, and engineering to understand ancient, phenomenological observations in metallurgy and mineralogy. Materials science still incorporates elements of physics, chemistry, and engineering. As such, the field was long considered by academic institutions as a sub-field of these related fields. Beginning in the 1940s, materials science began to be more widely recognized as a specific and distinct field of science and engineering, and major technical universities around the world created dedicated schools of the study. 
Many of the most pressing scientific problems humans currently face are due to the limits of the materials that are available. Thus, breakthroughs in materials science are likely to affect the future of technology significantly., In physics and materials science, the Curie temperature, or Curie point, is the temperature at which certain materials lose their permanent magnetic properties, to be replaced by induced magnetism. The Curie temperature is named after Pierre Curie, who showed that magnetism was lost at a critical temperature., Yttrium iron garnet ( YIG ) is a kind of synthetic garnet , with chemical composition Y3Fe2 ( FeO4 ) 3 , or Y3Fe5O12 . It is a ferrimagnetic material with a Curie temperature of 560 K. YIG may also be known as Yttrium ferrite garnet , or as Iron yttrium oxide or Yttrium iron oxide , the latter two names usually associated with powdered forms . In YIG , the five iron ( III ) ions occupy two octahedral and three tetrahedral sites , with the yttrium ( III ) ions coordinated by eight oxygen ions in an irregular cube . The iron ions in the two coordination sites exhibit different spins , resulting in magnetic behavior . By substituting specific sites with rare earth elements , for example , interesting magnetic properties can be obtained . YIG has a high Verdet constant which results in the Faraday effect , high Q factor in microwave frequencies , low absorption of infrared wavelengths down to 450 nm , and very small linewidth in electron spin resonance . These properties make it useful for MOI ( magnetic optical imaging ) applications in superconductors . YIG is used in microwave , acoustic , optical , and magneto - optical applications , e.g. microwave YIG filters , or acoustic transmitters and transducers . It is transparent for light wavelengths over 600 nm . It also finds use in solid - state lasers in Faraday rotators , in data storage , and in various nonlinear optics applications ., Physics (from , from "phúsis" "nature") is the natural science that involves the study of matter and its motion and behavior through space and time, along with related concepts such as energy and force. One of the most fundamental scientific disciplines, the main goal of physics is to understand how the universe behaves., An abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing which leads to part of the workpiece being worn away by friction. While finishing a material often means polishing it to gain a smooth, reflective surface, the process can also involve roughening as in satin, matte or beaded finishes. In short, the Ceramics which are used to cut, grind and polish other softer materials are known as Abrasives., Pierre Curie (15 May 1859  19 April 1906) was a French physicist, a pioneer in crystallography, magnetism, piezoelectricity and radioactivity. In 1903 he received the Nobel Prize in Physics with his wife, Marie Skodowska-Curie, and Henri Becquerel, "in recognition of the extraordinary services they have rendered by their joint researches on the radiation phenomena discovered by Professor Henri Becquerel"., The Bronze Age is a period characterized by the use of bronze, proto-writing, and other early features of urban civilization. The Bronze Age is the second principal period of the three-age Stone-Bronze-Iron system, as proposed in modern times by Christian Jürgensen Thomsen, for classifying and studying ancient societies., Subject: yttrium iron garnet, Relation: instance_of, Options: (A) age (B) april (C) art (D) cut (E) design (F) emphasis (G) energy (H) field (I) fine (J) force (K) gemstone (L) goal (M) group (N) material (O) matter (P) may (Q) mineral (R) motion (S) natural science (T) physics (U) point (V) principal (W) prize (X) process (Y) radioactivity (Z) science ([) stone (\) surface (]) temperature (^) three (_) value (`) writing
