 Passage 2:Relations between the people of Afghanistan and India traces to the Indus Valley Civilisation. Following Alexander the Great's brief occupation, the successor state of the Seleucid Empire controlled the region known today as Afghanistan. In 305 BCE, they ceded much of it to the Indian Maurya Empire as part of an alliance treaty. The Mauryans brought Buddhism from India and controlled the area south of the Hindu Kush. Their decline began 60 years after Ashoka's rule ended, leading to the Hellenistic reconquest of the region by the Greco-Bactrians. Much of it soon broke away from the Greco-Bactrians and became part of the Indo-Greek Kingdom. The Indo-Greeks had been defeated and expelled by the Indo-Scythians in the late 2nd century BCE. Much of Afghanistan has been influenced by Buddhist, Hindu and Zoroastrian cultures until the arrival of Islam in the 7th century. But despite many Afghans converting to Islam, the Muslims and Hindus lived side by side.
 Passage 3:There is evidence that the Second Bulgarian Empire ruled at least nominally the Wallachian lands up to the Rucăr–Bran corridor as late as the late 14th century. In a charter by Radu I, the Wallachian voivode requests that tsar Ivan Alexander of Bulgaria order his customs officers at Rucăr and the Dâmboviţa River bridge to collect tax following the law. The presence of Bulgarian customs officers at the Carpathians indicates a Bulgarian suzerainty over those lands, though Radu's imperative tone hints at a strong and increasing Wallachian autonomy. Under Radu I and his successor Dan I, the realms in Transylvania and Severin continued to be disputed with Hungary. Basarab was succeeded by Nicholas Alexander, followed by Vladislav I. Vladislav attacked Transylvania after Louis I occupied lands south of the Danube, conceded to recognize him as overlord in 1368, but rebelled again in the same year; his rule also witnessed the first confrontation between Wallachia and the Ottoman Empire (a battle in which Vladislav was allied with Ivan Shishman). After the Magyar conquest (10-11th century), Transylvania had become an autonomous and multi-ethnic voivodeship led by a voivode appointed by the King of Hungary until the 16th century. Several Kings of Hungary invited settlers from Central and Western Europe, such as the Saxons, to come to Transylvania and occupy the region. The Szeklers were brought to southeastern Transylvania as border guards. Romanians are mentioned by the Hungarian documents (township called Olahteluk) in the 13th century (1283) in Bihar County. The "land of Romanians" (Terram Blacorum) appeared in Fogaras, and this area was mentioned under the name "Olachi" in 1285. After the collapse of the Hungarian Kingdom (following the disastrous Battle of Mohács, 1526) the region became the independent Principality of Transylvania until 1711.

 Passage 2:While all other places in the Verbandsgemeinde can trace their foundings back to Frankish times and the Early Middle Ages, Neu-Bamberg's roots go back only as far as the Late Middle Ages; it is thus the newest place in the collective municipality. It is possible that Saint Maximin's Abbey in Trier once had landholds in what is now Neu-Bamberg, from which the Raugraves’ landhold arose, to which belonged the porphyry crag in the Appelbach valley, upon which, about 1250, they began building the castle. When the Raugraves founded this Neue Baumburg ("New Baumburg") about 1200 after building the Alte Baumburg ("Old Baumburg"), a new village arose below it. The villagers of nearby Sarlesheim gave their old village up and moved to this new one. Also living in the village were service personnel who had to care for the lordly estate, the livestock, the grazing land and the cropfields. In a 1253 document, the stronghold's existence is witnessed for the first time. On 13 March of that year, Raugrave Heinrich I and his brother Rupprecht II, together with their cousin Konrad I from the Old Baumburg, settled the mutual arrangements for the inheritance rights to their holdings. To distinguish their new comital seat from the old castle, the Alte Baumburg on the heights at the edge of the Alsenz valley, the Raugraves named the new castle Neue Baumburg, from which developed, after various shifts in pronunciation over the centuries, to "Neu-Bamberg". Nevertheless, the 1253 document does not put a name to this place, but rather says: Novum castrum apud Sarlesheim ("new castle near Sarlesheim"). Sarlesheim was a village that lay right near what is now the village of Neu-Bamberg, but later vanished. It had its first documentary mention together with the castle in the Raugraves’ 1253 document. The castle is nowadays a ruin crowning the crag where it was built. It can be seen far beyond the village. Just when the Raugraves, who instituted a constituent county here on their own territory, laid the foundation stone for the complex and completed it is unknown. The document mentioned above was the first to bear witness to its past. It seems clear, though, that by that time, it had been largely completed, at least in its most important parts. Already by the late 13th century, quite a big village had arisen here. The first Jews settled here in 1276 and in 1320, Emperor Ludwig, at Raugrave of Altenbaumburg Georg II's request, afforded the village Imperial protection. The castle and the village that had by now arisen were mentioned by name in a 1285 document. On 1 October of that year, Raugrave Heinrich II transferred to his wife Adelheid, born a countess of Sayn, the castle with all its walls and mountain perimeter as a widow's seat. Another document from 1297 describes the village as a Stadt ("town"). The rulers allowed the townsmen such rights, freedoms and favours as those enjoyed by the Oppenheimers. Furthermore, in 1330, the king granted Neu-Bamberg the right to hold a weekly market on Mondays. This shows that the settlement was a particular candidate for fostering. In 1337, the Raugraves pledged a half share in the castle and the small town of Neu-Bamberg to Archbishop of Mainz Heinrich III against a payment of 1,300 pounds in Heller. In 1369, the Counts Palatine of the Rhine, as well as a few towns, managed to secure entry rights to the half of the town that had remained in the Raugraves’ hands. After 1400, the shares in the ownership of the village were as follows: the Electorate of Mainz held a five-eighths share; the Lords of Daun/Counts of Falkenstein held a one-eighth share; the Counts of Sponheim held a two-eighths share, although by 1403, they had transferred their ownership share to Johann, Marshal of Waldeck. Neu-Bamberg formed an Amt in its own right within the Electorate of Mainz, and its territory also included the villages of Volxheim, Siefersheim, Wöllstein, Gumbsheim and Pleitersheim, along with each one's outlying countryside. Electoral Mainz's Praefectura Neobaumbergensis, as this was called, existed until the French Revolution. It kept its seat at the building that later served as a school and now as the municipal hall. In 1467, Prince-Archbishop-Elector Adolf II of Mainz pledged part of Neu-Bamberg to Count Wirich VII of Daun-Falkenstein. When this part passed by way of inheritance to the Duke of Lorraine in 1661, the then Prince-Archbishop-Elector of Mainz redeemed it in 1663. When a dispute broke out in 1668 with Elector Palatine Karl Ludwig over certain thoroughfare rights through Neu-Bamberg, the Prince-Archbishop-Elector of Mainz sued the Elector Palatine at the Reichskammergericht. The ruling on the dispute was just transferred to the Counts Palatine's declared adversaries, the Margraves of Baden, who quickly assigned the whole Neu-Bamberg landhold to the Archbishop of Mainz. In the disagreement over the local lordship, the castle and the village's fortifications were destroyed. In 1717, Neu-Bamberg was lastingly assigned by treaty in 1717 to the Electorate of Mainz, thereafter becoming an Electoral Mainz Amt to which the Electoral Mainz villages of Volxheim and Siefersheim were subject, as were Wöllstein, Gumbsheim and Pleitersheim, which were jointly ruled with Nassau-Saarbrücken. Mainz held the small castle town until the French conquest in the late 18th century. High jurisdiction is one of the most prominent features of mediaeval and even early-modern lordly power, with the gallows as its hallmark. Hence, it is to be understood that the execution places were to be set up in such exposed, widely visible spots as the Galgenberg ("Gallows Mountain") near Neu-Bamberg, which climbs up steeply right behind the Weidenmühle (mill) on the road going towards Wonsheim. The surroundings up at the hilltop where the gallows stood gives the same grim impression that came to mind when people who lived centuries ago thought of such places: bare, infertile land covered only in sparse grass, above which here and there only scanty shrubs grew. The last of the likely not few times when Neu-Bamberg was pillaged and plundered over its eventful history came in October 1796 by French Revolutionary troops. It lasted two days. Just before this event, the French had been engaging the Austrians nearby. The plunderers took all the village's livestock away with them to their camp. The Revolution of 1848 echoed lastingly in this small castle village, which in 1815 already had 478 inhabitants. An eyewitness, master tinsmith Karl Luttenberger, later told the following:One evening fire could be seen burning all round on the heights. Our townsman Johann Schlamp III, a freedom-fighter captain, fetched himself the Ries orchestra's big drum out of the dance hall, a wooden spoon from the kitchen and worked his way through the laneways in such a way that he soon had a goodly number of people behind him. Thereupon, a parade to the Schloßberg ("Castle Mountain") formed… A militia was also formed, with wooden shotguns, who met one Sunday with those from Fürfeld and Wonsheim. The meeting, which had begun with much enthusiasm ended less praiseworthily: during a drinking binge, an argument, and then a fight, broke out. When in the end the movement was beaten by the Prussians, the militiamen wished they had never said or done anything. In 1866, four men from Neu-Bamberg went to war in the Prussian forces against Austria, fighting in the Austro-Prussian War, among them Philipp and Michael Bremmer, who also fought alongside 17 others from the village in the Franco-Prussian War (1870–1871); one of them did not come back from the latter war. It was, however, not only war and other disputes that defined village life at that time. The local stone industry was experiencing decisive growth through technical innovation. In 1898, when the Sprendlingen–Fürfeld railway line was completed, stone could be shipped by rail to its various destinations. Shortly thereafter, trucks were also hauling stone cargoes. Steam engines, which drove the gravel quarries, also made it possible to increase production, as did electricity, which began to be transmitted to the village from Kreuznach in 1917. As early as 1909, Neu-Bamberg also enjoyed the modern convenience of a watermain. The village's sportsmen joined together in 1906 to form the Turn- und Sportverein (gymnastic and sport club). The First World War tore many young men from Neu-Bamberg. Twenty-four of them fell in that war, and six were listed as missing in action.
 Passage 3:Colonel Patrick Roland John (born Roseau, 7 January 1938) was the Prime Minister of Dominica as well as the Premier of Dominica. During his premiership Dominica gained independence from the United Kingdom and he became the first Prime Minister of Dominica. He was leader of the Waterfront and Allied Workers' Union and mayor of Roseau before being elected to the legislature in 1970. He took on prime ministerial duties in 1974 following the resignation of Edward Oliver LeBlanc. After mass protest forced him to resign, John unsuccessfully attempted to overthrow the government of Prime Minister Eugenia Charles with the backing of white supremacist groups (in what became dubbed "Operation Red Dog"). As a result, he was jailed for twelve years, of which he served five years.

Question: In what year was the railway company that was authorized to build two extensions in 1873 founded? Passage 1:In 1873, the Hoylake and Birkenhead Railway was authorised to construct two extensions to its lines. One was a short connecting section near to Birkenhead docks, and the other was the extension from Hoylake to West Kirby. The station and the extension were opened on 1 April 1878 as the terminus of the Wirral Railway's route from Birkenhead Park station. The station's original signal box was built in 1886, to a London and North Western Railway (LNWR) design. This signal box was removed and replaced in 1932. After the opening of the Mersey Railway Tunnel in 1886, carriages were operated through Birkenhead Park, every half-hour, all the way to James Street station in Liverpool. As traffic increased, the line into West Kirby was doubled, from a single track, in 1896. After a board meeting on 28 October 1895, it was decided to extend the line from Hooton, into West Kirby. The station was relocated on the western side of the original station, with an enlarged island platform and rebuilt, in 1898-9, in red brick, with a turreted clock tower and mock Tudor frontage. A further platform was constructed for the Hooton line, on the eastern side of the original station. The site of the original station was used for goods sidings. In the present day, this is the site of The Concourse, a community building operated by Wirral Metropolitan Borough Council.
 Passage 2:Meléndez began his wrestling career in 1951 at age 18. During a lengthy tenure in his native Puerto Rico, he went under various monikers and learned the ropes with the likes of Pedro Morales and Carlos Colón Sr.. Meléndez made his United States debut at Sunnyside Garden in Long Island, New York in 1963. Primarily using the name Gypsy Joe by this point, he mainly worked for Nick Gulas and later Jerry Jarrett in the Southeastern region, particularly Mid-Southern Wrestling. During his Gulas run, he was often teamed with heels like Tojo Yamamoto, with whom he formed the No Pain Train, and The Cuban Assassin. He also joined forces with Frank Martinez to be collectively known as the Blue Infernos. The masked duo would attain tag team championships on numerous occasions. By the 1970s, Gypsy Joe was a local star of Chattanooga, Tennessee, regularly performing at Soldiers and Sailors Memorial Auditorium on Saturdays and appearing on local WDEF-TV. His career wasn't limited to the South, however, winning championships around the country as well as in Canada’s Stampede Wrestling.
 Passage 3:Coming off their win over the Steelers the Jets played an interconference duel with the Bears. In the first quarter the Jets trailed early as kicker Robbie Gould got a 37-yard field goal, followed by Matt Forte getting a 22-yard TD run. The Jets pulled ahead with RB Shonn Greene getting a 3-yard TD run, followed by CB Dwight Lowery returning an interception 20 yards for a touchdown, followed by RB LaDainian Tomlinson getting a 3-yard TD run letting the Jets lead 21–10. The lead was narrowed as QB Jay Cutler scrambled 2 yards for a touchdown, but was soon extended as kicker Nick Folk made a 26-yard field goal. They trailed again with Cutler completing a 40 and a 25-yard TD pass to wide receivers Devin Hester and Johnny Knox respectively, but soon were able to tie the game with QB Mark Sanchez throwing a 23-yard TD pass to WR Santonio Holmes. The Bears escaped the tie with Cutler finding Knox again on a 26-yard TD pass. The Jets tried to come back, but only came away with a 34-yard field goal from Folk. When the Jets got the ball back, Sanchez threw a pass intended for Holmes, only to be intercepted by safety Chris Harris with 0:58 to go.
