Input: Context: Russia (from the  Rus'), also officially known as the Russian Federation, is a country in Eurasia. At , Russia is the largest country in the world by surface area, covering more than one-eighth of the Earth's inhabited land area, and the ninth most populous, with over 140 million people at the end of March 2016. The European western part of the country is much more populated and urbanised than the eastern, about 77% of the population live in European Russia. Russia's capital Moscow is one of the largest cities in the world, other major urban centers include Saint Petersburg, Novosibirsk, Yekaterinburg, Nizhny Novgorod and Samara., The Roman Empire (Koine and Medieval Greek:   , tr. ) was the post-Roman Republic period of the ancient Roman civilization, characterized by government headed by emperors and large territorial holdings around the Mediterranean Sea in Europe, Africa and Asia. The city of Rome was the largest city in the world BC AD, with Constantinople (New Rome) becoming the largest around 500 AD, and the Empire's populace grew to an estimated 50 to 90 million inhabitants (roughly 20% of the world's population at the time). The 500-year-old republic which preceded it was severely destabilized in a series of civil wars and political conflict, during which Julius Caesar was appointed as perpetual dictator and then assassinated in 44 BC. Civil wars and executions continued, culminating in the victory of Octavian, Caesar's adopted son, over Mark Antony and Cleopatra at the Battle of Actium in 31 BC and the annexation of Egypt. Octavian's power was then unassailable and in 27 BC the Roman Senate formally granted him overarching power and the new title "Augustus", effectively marking the end of the Roman Republic., Asia is Earth's largest and most populous continent, located primarily in the eastern and northern hemispheres and sharing the continental landmass of Eurasia with the continent of Europe. Asia covers an area of , about 30% of Earth's total land area and 8.7% of the Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Asia is notable for not only its overall large size and population, but also dense and large settlements as well as vast barely populated regions within the continent of 4.4 billion people., The Battle of Adrianople (9 August 378), sometimes known as the Battle of Hadrianopolis, was fought between an Eastern Roman army led by the Eastern Roman Emperor Valens and Gothic rebels (largely Thervings as well as Greutungs, non-Gothic Alans, and various local rebels) led by Fritigern. The battle took place about north of Adrianople (modern Edirne in European Turkey, near the border with Greece and Bulgaria) in the Roman province of Thracia. It ended with an overwhelming victory for the Goths and the death of Emperor Valens., Ermanaric ( Gothic : Aírmanareiks ; Latin : Ermanaricus ; Old English : Eormenric ; Old Norse : Jrmunrekr ; died 376 ) was a Greuthungian Gothic King who before the Hunnic invasion evidently ruled a sizable portion of Oium , the part of Scythia inhabited by the Goths at the time . He is mentioned in two Roman sources ; the contemporary writings of Ammianus Marcellinus and in Getica by the 6th - century historian Jordanes . Modern historians have postulated that Ermanaric at one point ruled a realm stretching from the Baltic Sea to the Black Sea as far eastwards as the Ural Mountains ., The Ural Mountains, or simply the Urals, are a mountain range that runs approximately from north to south through western Russia, from the coast of the Arctic Ocean to the Ural River and northwestern Kazakhstan.
The mountain range forms part of the conventional boundary between the continents of Europe and Asia. Vaygach Island and the islands of Novaya Zemlya form a further continuation of the chain to the north into the Arctic Ocean., Filimer was an early Gothic king, according to Jordanes. He was the son of Gadareiks and the fifth generation since Berig settled with his people in Gothiscandza. When the Gothic nation had multiplied Filimer decided to move his people to Scythia where they defeated the Sarmatians. They then named their new territory "Oium", meaning "in the waterlands". This migration would have taken place about 230 years before Jordanes wrote his ""Origin of the Goths""., Longitude (or , Australian and British also ), is a geographic coordinate that specifies the east-west position of a point on the Earth's surface. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (). Meridians (lines running from the North Pole to the South Pole) connect points with the same longitude. By convention, one of these, the Prime Meridian, which passes through the Royal Observatory, Greenwich, England, was allocated the position of zero degrees longitude. The longitude of other places is measured as the angle east or west from the Prime Meridian, ranging from 0° at the Prime Meridian to +180° eastward and 180° westward. Specifically, it is the angle between a plane containing the Prime Meridian and a plane containing the North Pole, South Pole and the location in question. (This forms a right-handed coordinate system with the axis (right hand thumb) pointing from the Earth's center toward the North Pole and the axis (right hand index finger) extending from Earth's center through the equator at the Prime Meridian.), The Baltic Sea (  ; ) is a sea of the Atlantic Ocean, enclosed by Scandinavia, Finland, the Baltic countries, and the North European Plain. It includes the Gulf of Bothnia, the Bay of Bothnia, the Gulf of Finland, the Gulf of Riga, and the Bay of Gdask. The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. A mediterranean sea of the Atlantic, with limited water exchange between the two bodies, the Baltic Sea drains through the Danish islands into the Kattegat by way of the straits of Øresund, the Great Belt, and the Little Belt., Oium or Aujum was a name for an area in Scythia, where the Goths, under King Filimer, arguably settled after leaving Gothiscandza, according to the "Getica" by Jordanes, written around 551. Jordanes does not give an etymology, but many scholars interpret this word as a dative plural to the widespread Germanic words *"auj-" or *"auw-" and means "well-watered meadow" or "island"., The Goths were an East Germanic people, two of whose branches, the Visigoths and the Ostrogoths, played an important role in the fall of the Western Roman Empire and the emergence of Medieval Europe. The Goths dominated a vast area, which at its peak under the Germanic king Ermanaric and his sub-king Athanaric possibly extended all the way from the Danube to the Don, and from the Black Sea to the Baltic Sea., Ammianus Marcellinus (born c. 325330 died c. 391400) was a Roman soldier and historian who wrote the penultimate major historical account surviving from Antiquity (preceding Procopius). His work, known as the Res Gestae, chronicled in Latin the history of Rome from the accession of the emperor Nerva in 96 to the death of Valens at the Battle of Adrianople in 378, although only the sections covering the period 353378 survive., The Black Sea is a body of water between Eastern Europe and Western Asia, bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. It is supplied by a number of major rivers, such as the Danube, Dnieper, Rioni, Southern Bug, and Dniester. The Black Sea has an area of (not including the Sea of Azov), a maximum depth of , and a volume of . It is constrained by the Pontic Mountains to the south and by the Caucasus Mountains to the east, and features a wide shelf to the northwest. The longest east-west extent is about ., De origine actibusque Getarum (""The Origin and Deeds of the Getae/Goths""), or the Getica, written in Late Latin by Jordanes (or "Iordanes/Jornandes") in or shortly after 551 AD, claims to be a summary of a voluminous account by Cassiodorus of the origin and history of the Gothic people, which is now lost. However, the extent to which Jordanes actually used the work of Cassiodorus is unknown. It is significant as the only remaining contemporaneous resource that gives the full story of the origin and history of the Goths. Another aspect of this work is its information about the early history and the customs of Slavs., Valens (328  9 August 378), fully "Flavius Julius Valens Augustus", was Eastern Roman Emperor from 364 to 378. He was given the eastern half of the empire by his brother Valentinian I after the latter's accession to the throne. Valens, sometimes known as the Last True Roman, was defeated and killed in the Battle of Adrianople, which marked the beginning of the collapse of the decaying Western Roman Empire., Procopius of Caesarea (; 500  554 AD) was a prominent late antique scholar from Palaestina Prima. Accompanying the Roman general Belisarius in the wars of the Emperor Justinian, he became the principal Byzantine historian of the 6th century, writing the "Wars" (or "Histories"), the "Buildings of Justinian" and the now-celebrated (and infamous) "Secret History". He is commonly held to be the last major historian of the ancient Western world., Romania is a sovereign state located in Southeastern Europe. It borders the Black Sea, Bulgaria, Ukraine, Hungary, Serbia, and Moldova. It has an area of and a temperate-continental climate. With 19.94 million inhabitants, the country is the seventh-most-populous member state of the European Union. The capital and largest city, Bucharest, with its 1,883,425 inhabitants is the sixth-largest city in the EU., The Nuclear Engine for Rocket Vehicle Application (NERVA) was a U.S. nuclear thermal rocket engine development program that ran for roughly two decades. NERVA was a joint effort of the U.S. Atomic Energy Commission (AEC) and NASA, managed by the Space Nuclear Propulsion Office (SNPO) until both the program and the office ended at the end of 1972., Riga is the capital and the largest city of Latvia. With 696,593 inhabitants (2015), Riga is the largest city of the Baltic states and home to one third of Latvia's population. The city lies on the Gulf of Riga, at the mouth of the Daugava. Riga's territory covers and lies between above sea level, on a flat and sandy plain., Finland , officially the Republic of Finland, is a sovereign state in Northern Europe. A peninsula with the Gulf of Finland to the south and the Gulf of Bothnia to the west, the country has land borders with Sweden to the northwest, Norway to the north, and Russia to the east. Estonia is south of the country across the Gulf of Finland. Finland is a Nordic country situated in the geographical region of Fennoscandia, which also includes Scandinavia. Finland's population is 5.5 million (2014), staying roughly on the same level over the past two decades. The majority of the population is concentrated in the southern region. In terms of area, it is the eighth largest country in Europe and the most sparsely populated country in the European Union., Flavius Magnus Aurelius Cassiodorus Senator (c. 485  c. 585), commonly known as Cassiodorus, was a Roman statesman and writer serving in the administration of Theoderic the Great, king of the Ostrogoths. "Senator" was part of his surname, not his rank., The Ostrogoths were the eastern branch of the later Goths (the other major branch being the Visigoths). The Ostrogoths traced their origins to the Greutungi  a branch of the Goths who had migrated southward from the Baltic Sea and established a kingdom north of the Black Sea, during the 3rd and 4th centuries. They built an empire stretching from the Black Sea to the Baltic. The Ostrogoths were probably literate in the 3rd century, and their trade with the Romans was highly developed. Their Danubian kingdom reached its zenith under King Ermanaric, who is said to have committed suicide at an old age when the Huns attacked his people and subjugated them in about 370., The Ural or Jayq/Zhayyq (, ), known as Yaik before 1775, is a river flowing through Russia and Kazakhstan in Eurasia. It originates in the southern Ural Mountains and ends at the Caspian Sea. At , it is the third-longest river in Europe after the Volga and the Danube, and the 18th-longest river in Asia. The Ural River is conventionally considered part of the boundary between the continents of Europe and Asia., 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"., Kazakhstan ( "Qazaqstan",  "Kazakhstan"), officially the Republic of Kazakhstan ("Qazaqstan Respwblïkas" "Respublika Kazakhstan"), is a transcontinental country in northern Central Asia and Eastern Europe. Kazakhstan is the world's largest landlocked country, and the ninth largest in the world, with an area of . Kazakhstan is the dominant nation of Central Asia economically, generating 60% of the region's GDP, primarily through its oil/gas industry. It also has vast mineral resources., Ukraine (tr. ) is a sovereign state in Eastern Europe, bordered by Russia to the east and northeast, Belarus to the northwest, Poland and Slovakia to the west, Hungary, Romania, and Moldova to the southwest, and the Black Sea and Sea of Azov to the south and southeast, respectively. Ukraine is currently in territorial dispute with Russia over the Crimean Peninsula which Russia annexed in 2014 but which Ukraine and most of the international community recognise as Ukrainian. Including Crimea, Ukraine has an area of , making it the largest country entirely within Europe and the 46th largest country in the world. It has a population of about 44.5 million, making it the 32nd most populous country in the world., In geography, latitude is a geographic coordinate that specifies the northsouth position of a point on the Earth's surface. Latitude is an angle (defined below) which ranges from 0° at the Equator to 90° (North or South) at the poles. Lines of constant latitude, or parallels, run eastwest as circles parallel to the equator. Latitude is used together with longitude to specify the precise location of features on the surface of the Earth.
Approximations employed.
Two levels of abstraction are employed in the definition of these coordinates. In the first step the physical surface is modelled by the geoid, a surface which approximates the mean sea level over the oceans and its continuation under the land masses. The second step is to approximate the geoid by a mathematically simpler reference surface. The simplest choice for the reference surface is a sphere, but the geoid is more accurately modelled by an ellipsoid. The definitions of latitude and longitude on such reference surfaces are detailed in the following sections. Lines of constant latitude and longitude together constitute a graticule on the reference surface. The latitude of a point on the "actual" surface is that of the corresponding point on the reference surface, the correspondence being along the normal to the reference surface which passes through the point on the physical surface. Latitude and longitude together with some specification of height constitute a geographic coordinate system as defined in the specification of the ISO 19111 standard., The Visigoths were the western branches of the nomadic tribes of Germanic peoples referred to collectively as the Goths. These tribes flourished and spread during the late Roman Empire in Late Antiquity, or the Migration Period. The Visigoths emerged from earlier Gothic groups (possibly the Thervingi) who had invaded the Roman Empire beginning in 376 and had defeated the Romans at the Battle of Adrianople in 378. Relations between the Romans and the Visigoths were variable, alternately warring with one another and making treaties when convenient. The Visigoths invaded Italy under Alaric I and sacked Rome in 410. After the Visigoths sacked Rome, they began settling down, first in southern Gaul and eventually in Spain and Portugal, where they founded the Visigothic Kingdom and maintained a presence from the 5th to the 8th centuries AD., Subject: ermanaric, Relation: date_of_birth, Options: (A) 1 (B) 10 (C) 140 (D) 1775 (E) 180 (F) 19 (G) 1972 (H) 20 (I) 230 (J) 27 (K) 29 (L) 30 (M) 325 (N) 328 (O) 330 (P) 370 (Q) 376 (R) 378 (S) 400 (T) 410 (U) 485 (V) 5 (W) 500 (X) 551 (Y) 554 (Z) 585 ([) 60 (\) 696 (]) 90 (^) 94
