[EX Q]: Context: The Umbau - Wagen or Umbauwagen was a type of German railway passenger coach operated by the Deutsche Bundesbahn ( DB ) which appeared in the mid- 1950s . The name means `` rebuild coach '' and they were made by rebuilding or converting former state railway ( Länderbahn ) compartment coaches , many of which were over 30 years old ., Deutsche Bahn AG (abbreviated as "DB", "DB AG" or "DBAG") is a German railway company. Headquartered in Berlin, it is a private joint-stock company (AG), with the Federal Republic of Germany being its single shareholder. Deutsche Bahn describes itself as the second-largest transport company in the world, after the German postal and logistics company Deutsche Post / DHL, and is the largest railway operator and infrastructure owner in Europe. It carries about two billion passengers each year., The Deutsche Bundesbahn or DB (German Federal Railway) was formed as the state railway of the newly established Federal Republic of Germany (FRG) on 7 September 1949 as a successor of the Deutsche Reichsbahn-Gesellschaft (DRG). The DB remained the state railway of West Germany until after German reunification, when it was merged with the former East German Deutsche Reichsbahn (DR) to form Deutsche Bahn AG, which came into existence on 1 January 1994., The German reunification was the process in 1990 in which the German Democratic Republic (GDR/East Germany) joined the Federal Republic of Germany (FRG/West Germany) to form the reunited nation of Germany, and when Berlin reunited into a single city, as provided by its then Grundgesetz constitution Article 23. The end of the unification process is officially referred to as German unity, celebrated on 3 October (German Unity Day). Following German reunification, Berlin was once again designated as the capital of united Germany., Subject: umbau-wagen, Relation: operator, Options: (A) deutsche bahn (B) deutsche bundesbahn (C) germany

[EX Q]: Context: In geography, statistics and archaeology, a settlement, locality or populated place is a community in which people live. A settlement can range in size from a small number of dwellings grouped together to the largest of cities with surrounding urbanized areas. Settlements may include hamlets, villages, towns and cities. A settlement may have known historical properties such as the date or era in which it was first settled, or first settled by a particular people., A marginal sea is a division of an ocean, partially enclosed by islands, archipelagos, or peninsulas, adjacent to or widely open to the open ocean at the surface, and/or bounded by submarine ridges on the sea floor., A ship canal is a canal especially intended to accommodate ships used on the oceans, seas or lakes to which it is connected, as opposed to a barge canal intended to carry barges and other vessels specifically designed for river and/or canal navigation. Because of the constraints of accommodating vessels capable of navigating large bodies of open water, a ship canal typically offers deeper water and higher bridge clearances than a barge canal of similar vessel length and width constraints. , France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans and had a total population of almost 67 million people as of January 2017. It is a unitary semi-presidential republic with the capital in Paris, the country's largest city and main cultural and commercial centre. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse and Bordeaux., 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., A village is a clustered human settlement or community, larger than a hamlet but smaller than a town, with a population ranging from a few hundred to a few thousand. Though often located in rural areas, the term urban village is also applied to certain urban neighbourhoods. Villages are normally permanent, with fixed dwellings; however, transient villages can occur. Further, the dwellings of a village are fairly close to one another, not scattered broadly over the landscape, as a dispersed settlement., Belgium , officially the Kingdom of Belgium, is a sovereign state in Western Europe bordered by France, the Netherlands, Germany, Luxembourg, and the North Sea. It is a small, densely populated country which covers an area of and has a population of about 11 million people. Straddling the cultural boundary between Germanic and Latin Europe, Belgium is home to two main linguistic groups: the Dutch-speaking, mostly Flemish community, which constitutes about 59% of the population, and the French-speaking, mostly Walloon population, which comprises 41% of all Belgians. Additionally, there is a small group of German-speakers who live in the East Cantons located around the High Fens area, and bordering Germany., Western Europe, also West Europe, is the region comprising the western part of the European continent. There may be differences between the geopolitical and purely geographic definitions of the term., Rotterdam is a city in the Netherlands, located in South Holland, within the RhineMeuseScheldt river delta at the North Sea. Its history goes back to 1270 when a dam was constructed in the Rotte river by people settled around it for safety. In 1340 Rotterdam was granted city rights by the Count of Holland and slowly grew into a major logistic and economic centre. Nowadays it is home to Europe's largest port and has a population of 633,471 (city proper), ranking second in the Netherlands. The Greater Rijnmond area is home to approximately 1.4 million people and the Rotterdam The Hague Metropolitan Area makes for the 168th most populous urban area in the world. Rotterdam is part of the yet larger Randstad conurbation with a total population of 7,100,000., The North Sea is a marginal sea of the Atlantic Ocean located between Great Britain, Scandinavia, Germany, the Netherlands, Belgium, and France. An epeiric (or "shelf") sea on the European continental shelf, it connects to the ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, with an area of around ., The continental shelf is an underwater landmass which extends from a continent, resulting in an area of relatively shallow water known as a shelf sea. Much of the shelves were exposed during glacial periods and interglacial periods., A ship is a large buoyant watercraft. Ships are generally distinguished from boats based on size, shape and cargo or passenger capacity. Ships are used on lakes, seas, rivers, and oceans for a variety of activities, such as the transport of people or goods, fishing, entertainment, public safety, and warfare. Historically, a "ship" was a sailing vessel with at least three square-rigged masts and a full bowsprit., The Hague (or "<nowiki>'</nowiki>s-Gravenhage" ) is a city located in the western coast of the Netherlands, and the capital city of the province of South Holland., Maassluis is a city in the western Netherlands, in the province of South Holland. The municipality had a population of in and covers of which water., South Holland is a province in the midwestern Netherlands. It has a population of just over 3.6 million (as of 2015) and a population density of about , making it the country's most populous province and one of the world's most densely populated areas. Situated on the North Sea in the west of the Netherlands, South Holland covers an area of , of which is water. It borders North Holland to the north, Utrecht and Gelderland to the east, and North Brabant and Zeeland to the south. The provincial capital is The Hague, while its largest city is Rotterdam., A sea is a large body of salt water that is surrounded in whole or in part by land. More broadly, "the sea" is the interconnected system of Earth's salty, oceanic watersconsidered as one global ocean or as several principal oceanic divisions. The sea moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. Although the sea has been traveled and explored since prehistory, the modern scientific study of the seaoceanographydates broadly to the British "Challenger" expedition of the 1870s. The sea is conventionally divided into up to five large oceanic sectionsincluding the International Hydrographic Organization's four named oceans (the Atlantic, Pacific, Indian, and Arctic) and the Southern Ocean; smaller, second-order sections, such as the Mediterranean, are known as "seas"., A country is a region that is identified as a distinct national entity in political geography. A country may be an independent sovereign state or one that is occupied by another state, as a non-sovereign or formerly sovereign political division, or a geographic region associated with sets of previously independent or differently associated people with distinct political characteristics. Regardless of the physical geography, in the modern internationally accepted legal definition as defined by the League of Nations in 1937 and reaffirmed by the United Nations in 1945, a resident of a country is subject to the independent exercise of legal jurisdiction., The Nieuwe Waterweg ( `` New Waterway '' ) is a ship canal in the Netherlands from het Scheur ( a branch of the Rhine - Meuse - Scheldt delta ) west of the town of Maassluis to the North Sea at Hook of Holland : the Maasmond , where the Nieuwe Waterweg connects to the Maasgeul . It is the artificial mouth of the river Rhine . The Nieuwe Waterweg , which opened in 1872 and has a length of approximately 20.5 kilometres ( 12.7 mi ) , was constructed to keep the city and port of Rotterdam accessible to seafaring vessels as the natural Meuse - Rhine branches silted up . The Waterway is a busy shipping route since it is the primary access to one of the busiest ports in the world , the Europoort of Rotterdam . At the entrance to the sea , a flood protection system called Maeslantkering has been installed ( completed in 1997 ) . There are no bridges or tunnels across the Nieuwe Waterweg ., The Hook of Holland is a town in the southwestern corner of Holland (hence the name; "hoek" means "corner"), at the mouth of the New Waterway shipping canal into the North Sea. The town is administered by the municipality of Rotterdam as a district of that city. Its district covers an area of 16.7 km, of which 13.92 km is land. On 1 January 1999 it had an estimated population of 9,400., An ocean (the sea of classical antiquity) is a body of saline water that composes much of a planet's hydrosphere. On Earth, an ocean is one of the major conventional divisions of the World Ocean, which covers almost 71% of its surface. These are, in descending order by area, the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic Oceans. The word "sea" is often used interchangeably with "ocean" in American English but, strictly speaking, a sea is a body of saline water (generally a division of the world ocean) partly or fully enclosed by land., The Atlantic Ocean is the second largest of the world's oceans with a total area of about . It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World"., The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union., The Kingdom of the Netherlands , commonly known as the Netherlands, is a sovereign state and constitutional monarchy with territory in western Europe and in the Caribbean., Utrecht is the capital and most populous city in the Dutch province of Utrecht. It is located in the eastern corner of the Randstad conurbation and is the fourth largest city in the Netherlands with a population of in ., Holland is a region and former province on the western coast of the Netherlands. The name "Holland" is also frequently used to informally refer to the whole of the country of the Netherlands. This usage is commonly accepted in other countries, and not entirely uncommon among the Dutch themselves, though some in the Netherlands and particularly in other regions of the country may find it undesirable, misleading or insulting., Canals and navigations are human-made channels for water conveyance (supply), or to service water transport vehicles. In the vernacular, both are referred to as 'canals', and in most cases, the engineered works will have a series of dams and locks that create areas of low speed current flow. These areas are referred to as" 'slack water levels'," often just called 'levels'.
The main difference between them is that a navigation parallels a river and shares part of its waters, its drainage basin and leverages its resources by building dams and locks to increase and lengthen its long stretches of "deep enough" slack water levels while staying in its valley. In contrast, a canal cuts across a drainage divide atop a ridge (however humble), generally requiring an external water source above the highest elevation. Many canals have been built at elevations towering over valleys and others water ways crossing far below. Cities need a lot of fresh water and many canals with sources of water at a higher level can deliver water to a destination where there is a lack of water. The Roman Empire's Aqueducts were such water supply canals., The English Channel ("the Sleeve" [hence ] "Sea of Brittany" "British Sea"), also called simply the Channel, is the body of water that separates southern England from northern France, and joins the southern part of the North Sea to the rest of the Atlantic Ocean., A town is a human settlement larger than a village but smaller than a city. The size definition for what constitutes a "town" varies considerably in different parts of the world., The world is the planet Earth and all life upon it, including human civilization. In a philosophical context, the world is the whole of the physical Universe, or an ontological world. In a theological context, the "world" is the material or the profane sphere, as opposed to the celestial, spiritual, transcendent or sacred. The "end of the world" refers to scenarios of the final end of human history, often in religious contexts., In modern politics and history, a parliament is a legislative, elected body of government. Generally a modern parliament has three functions: representing the electorate, making laws, and overseeing the government ("i.e.", hearings, inquiries)., A lake is an area of variable size filled with water, localized in a basin, that is surrounded by land, apart from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, and therefore are distinct from lagoons, and are also larger and deeper than ponds, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which are usually flowing. Most lakes are fed and drained by rivers and streams., BARGE, the Big August Rec.Gambling Excursion, is a yearly convention held in Las Vegas during the first weekend of August. It consists of a series of tournaments both of poker and other gambling games, as well as a banquet and a host of informal social and gambling activities organized by attendees. Some of the well-known poker players who have participated either as speakers or players in the no limit holdem tournament include: Howard Lederer, Chris Ferguson, Phil Hellmuth Jr, Greg Raymer, Mason Malmuth, David Sklansky, Mike Caro, Matt Matros, Linda Johnson, Phil Gordon, Paul Phillips, Andy Bloch, William Chen, Doyle Brunson and many others., The Norwegian Sea is a marginal sea in the North Atlantic Ocean, northwest of Norway. It is located between the North Sea (i.e. north of the United Kingdom) and the Greenland Sea and adjoins the North Atlantic Ocean to the west and the Barents Sea to the northeast. In the southwest, it is separated from the Atlantic Ocean by a submarine ridge running between Iceland and the Faroe Islands. To the North, the Jan Mayen Ridge separates it from the Greenland Sea., Amsterdam is the capital and most populous municipality of the Kingdom of the Netherlands. Its status as the capital is mandated by the Constitution of the Netherlands, although it is not the seat of the government, which is The Hague. Amsterdam has a population of 847,176 within the city proper, 1,343,647 in the urban area, and 2,431,000 in the Amsterdam metropolitan area. The city is located in the province of North Holland in the west of the country. The metropolitan area comprises much of the northern part of the Randstad, one of the larger conurbations in Europe, with a population of approximately 7 million., The Netherlands  is the main constituent country of the Kingdom of the Netherlands. It is a densely populated country located in Western Europe with three island territories in the Caribbean. The European part of the Netherlands borders Germany to the east, Belgium to the south, and the North Sea to the northwest, sharing maritime borders with Belgium, the United Kingdom, and Germany. The largest cities in the Netherlands are Amsterdam, Rotterdam, The Hague and Utrecht. Amsterdam is the country's capital, while The Hague holds the Dutch seat of government and parliament. The name "Holland" is used to refer informally to the whole of the country of the Netherlands., Great Britain, also known as Britain , is a large island in the north Atlantic Ocean off the northwest coast of continental Europe. With an area of , Great Britain is the largest European island and the ninth-largest in the world. In 2011 the island had a population of about 61 million people, making it the world's third-most populous island after Java in Indonesia and Honshu in Japan. The island of Ireland is situated to the west of it, and together these islands, along with over 1,000 smaller surrounding islands, comprise the British Isles archipelago., 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. With about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular immigration destination in the world. Germany's capital and largest metropolis is Berlin. Other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart and Düsseldorf., Scandinavia is a historical and cultural region in Northern Europe characterized by a common ethnocultural North Germanic heritage and mutually intelligible North Germanic languages., The Caribbean (or ) is a region that consists of the Caribbean Sea, its islands (some surrounded by the Caribbean Sea and some bordering both the Caribbean Sea and the North Atlantic Ocean) and the surrounding coasts.
