Passage: The Greek Navy was relatively modern, strengthened by the recent purchase of numerous new units and undergoing reforms under the supervision of a British mission. Invited by Prime Minister Venizelos in 1910, the mission began its work upon its arrival in May 1911. Granted extraordinary powers and led by Vice Admiral Lionel Grand Tufnell, it thoroughly reorganized the Navy Ministry and dramatically improved the number and quality of exercises in gunnery and fleet maneuvers. In 1912, the core unit of the fleet was the fast armoured cruiser Georgios Averof, completed in 1910 and, at that time, the fastest and most modern warship in the combatant navies. It was complemented by three rather antiquated battleships of the Hydra class. There were also eight destroyers built in 1906-1907, and six new destroyers that were hastily bought in summer 1912 as the imminence of war became apparent. Nevertheless, at the outbreak of the war, the Greek fleet was far from ready. The Ottoman battlefleet retained a clear advantage in number of ships, speed of the main surface units and, more importantly, in the number and caliber of the ships' guns. In addition, as the war caught the fleet in the middle of its expansion and reorganization, fully a third of the fleet only reached Greece after hostilities had started, forcing the navy to reshuffle crews, who consequently suffered from lacking familiarization and training time. Coal stockpiles and other war stores were also in short supply, while the Georgios Averof had arrived with barely any ammunition, and would remain so until late November.
Question: What is the former year when eight destroyers were built?

Passage: The War of the Limburg Succession, was a series of conflicts between 1283 and 1289 for the succession in the Duchy of Limburg. The cause of the War of the Limburg Succession was the death of Waleran IV, Duke of Limburg in 1280, and his only daughter Ermengarde of Limburg in 1283. Waleran IV had no sons and Ermengarde had no children. Ermergarde had married Reginald I of Guelders, who now claimed the Duchy of Limburg. However, Waleran's nephew Adolf VIII of Berg, son of his elder brother Adolf VII of Berg, also claimed the Duchy. Unable to assert his claims, he sold them in 1283 to the mighty John I, Duke of Brabant. Between 1283 and 1288, several smaller confrontations occurred between both sides, none of them decisive. Meanwhile, most of the other local powers chose sides. Siegfried II of Westerburg, the Archishop of Cologne and ruler of the Electorate of Cologne, traditional enemy of the Duke of Brabant, forged an alliance with Reginald I, joined by Henry VI, Count of Luxembourg, and his brother Waleran I of Luxembourg, Lord of Ligny, as well as by Adolf, King of Germany. On the other side the Counts of Mark took the chance to affirm their independence from the Archbishop of Cologne and together with the Counts of Loon, Tecklenburg, and Waldeck allied with Brabant and Berg. The citizens of the City of Cologne, eager to emancipate themselves from the Archbishop's rule, also joined this alliance. After the decisive Battle of Worringen in 1288, won by Duke John I of Brabant and his allies, the Duchy of Limburg came in the possession of the Duke of Brabant. The City of Cologne gained its independence from the Archbishopric and finally the status of an Imperial city in 1475.
Question: How many people did Duke of Brabant forge an alliance with?

Passage: He played in 64 games for the Orioles, hitting for .257, 34 RBIs, 10 home runs and 59 hits. On September 6, 1996, he hit his 500th career home run off Felipe Lirafittingly, the home run came as a member of the Orioles, and also came exactly one year to the day that Ripken had broken Lou Gehrigs streak of 2,130 consecutive games played. Having already reached the 3,000 hits plateau the previous season, Murray joined Willie Mays and Hank Aaron as the only players ever to have hit at least 500 home runs and amassed 3,000 or more hits in their careers. Rafael Palmeiro, Alex Rodriguez, and Albert Pujols have since joined the club. He participated in the Orioles playoff run, as the team advanced to the 1996 American League Championship Series against the Yankees after having beat his old team in the ALDS. In nine total postseason games, he went 10-for-30 while hitting one home run. After being granted free agency by the Orioles, Murray was signed as a free agent by the Los Angeles Angels on December 18, 1996. He played 55 total games in the 1997 season, 46 with the Angels and 9 with the Dodgers. He had a .219 batting average along with 15 RBIs, 3 home runs, and 35 hits. His last home run was with the Angels, hitting one off Bob Tewksbury in the second inning in a 4-3 loss. He was released by the Angels on August 14. On August 20, he was signed by the Dodgers. In nine total games with the Dodgers, he had a .294 batting average, 3 RBIS and 2 hits. On October 30, he was granted free agency. He retired after the 1997 season with 504 home runs; as of 2011, Mickey Mantle is the only switch-hitter who has hit more home runs (536). Murray hit a home run from both sides of the plate in 11 games; he retired tied with Chili Davis for first place in this category. This co-record has since been broken by Mark Teixeira.
