Example Input: Question: How long had he been king when Perseud led the Macedonians in the Third Macedonian War? Passage 1:1964 is a documentary film produced by Insignia Films for the American Experience series about political, social and cultural events in the United States for the calendar year 1964. It is based partly on Jon Margolis book The Last Innocent Year: America in 1964. The documentary depicts the year 1964 as significant and epic in that following the assassination of President John F. Kennedy in late 1963, 1964, as a presidential election year, becomes a departure point for American history, with lasting effects today. It is also the year of the British Invasion led by the Beatles, when Cassius Clay fights Sonny Liston for the World Heavyweight Championship, the year after Betty Friedan's book, The Feminine Mystique, is published, and the year Republican activist, Phyllis Schlafly's book, A Choice, Not an Echo, is published. It is also the year of Freedom Summer, an initiative by the Student Nonviolent Coordinating Committee to register African-Americans in Mississippi, the subsequent murders of Chaney, Goodman, and Schwerner, three CORE activists, in Mississippi by white supremacists that created a national sensation, and the Harlem riot of 1964, culminating in the Berkeley Free Speech Movement at the University of California at Berkeley. A recurrent theme of the film is its departure as a presidential election year, with President Lyndon B. Johnson running as the expected Democratic Party nominee and the nomination of U.S. Senator Barry Goldwater selected through a grassroots campaign for the Republican nomination for President of the United States, that defines the future divisions of the US political party competition.
 Passage 2:The Battle of Callinicus () was fought in 171 BC between the Kingdom of Macedon and the Roman Republic near a hill called Callinicus, close to the Roman camp at Tripolis Larisaia, five kilometres north of Larissa, the capital of Thessaly. It was fought during the first year of the Third Macedonian War (171-168 BC). The Macedonians were led by their king, Perseus of Macedon, while the Roman force was led by the consul Publius Licinius Crassus. The Macedonians were supported by Cotys IV, the king of the Odrysian kingdom (the largest state in Thrace) and his forces, by Cretan mercenaries and by auxiliaries of mixed nationalities. The Romans had their Italian allies with them and were supported by soldiers provided by Eumenes II of Pergamon, as well as a force of Thessalian cavalry and Greek allies. The battle saw the deployment of troops with cavalry intermixed with light infantry. Although the battle was actually inconclusive because Perseus withdrew before it came to a conclusion, it was considered a Macedonian victory because the Romans suffered heavy casualties.
 Passage 3:During the Napoleonic wars, Île de France became a base from which the French navy, including squadrons under Rear Admiral Linois or Commodore Jacques Hamelin, and corsairs such as Robert Surcouf, organised raids on British merchant ships. The raids (see Battle of Pulo Aura and Mauritius campaign of 1809–1811) continued until 1810 when the British sent a strong expedition to capture the island. The first British attempt, in August 1810, to attack Grand Port resulted in a French victory, one celebrated on the Arc de Triomphe in Paris. A subsequent and much larger attack launched in December of the same year from Rodrigues, which had been captured a year earlier, was successful. The British landed in large numbers in the north of the island and rapidly overpowered the French, who capitulated (see Invasion of Isle de France). In the Treaty of Paris (1814), the French ceded Île de France together with its territories including Rodrigues and Seychelles to Great Britain. The island then reverted to its former name, 'Mauritius'.

Example Input: Question: Who succeeded Khalid's son as ruler of  the family's stronghold? Passage 1:The team began the 1888 season with part-time outfielder, Dave Rowe, as their player-manager. On April 18, they suffered a 10–3 loss to Tony Mullane and the Cincinnati Reds in their first game, however, they collected their first win the next day. Although they had a win–loss record of 43–89 in their initial season, finishing last out of the league's eight teams, and went through two managerial changes, there were a couple of bright moments; on June 6, Henry Porter threw a no-hitter, and on June 13, Sam Barkley hit for the cycle. The franchise's only future Hall of Fame player, "Slidin'" Billy Hamilton, began his career as a part-time outfielder in 1888, and was their starting right fielder in 1889. Bill Watkins, who had finished the 1888 season as the team's manager, stayed in that role for the full 1889 season, and guided them to an improved win–loss record of 55–82, with two ties, finishing seventh among the league's eight teams.
 Passage 2:The original Munster Football Association was founded in 1901 and it is believed that a Munster League was founded within a few years. The 1909–10 season saw six teams representing the Highland Light Infantry, the Royal Welch Fusiliers, the Durham Light Infantry, the Sherwood Foresters, the King's Regiment and Haulbowline all playing in the Munster League First Division. In the Munster Cup the Highland Light Infantry lost 1–0 to the Royal Welsh Fusilers in the final played at Turner's Cross. However this league was effectively disbanded during the First World War and Irish War of Independence era. In 1921 Harry Buckle, a former Ireland international, settled in Cork and began working for the Ford Motor Company. Finding little or no association football activity in the city, Buckle initially founded Fordsons F.C. and then helped found the County Cork–based South Munster League for the team to play in. In addition to playing and coaching with the new club, Buckle also served as president of the Tipperary/Limerick based – North Munster League and helped reform the Munster Football Association. By 1922–23 the South Munster League and North Munster Leagues had effectively merged to become the Munster Senior League. Barrackton United of the South Munster League became the first post–First World War Munster Senior League champions after defeating Cahir Park F.C. of the North Munster League in a play-off.
 Passage 3:Khalid was a member of the Shayban tribe, dominant in the region of Diyar Bakr in the northern Jazira, and third son of Yazid ibn Mazyad al-Shaybani, who served twice as Arab governor (ostikan) of Arminiya (a large province encompassing the whole of Transcaucasia). Khalid served in the same office no less than four times: in 813/814, 828–832, briefly in 841 and again under Caliph al-Wathiq (r. 842–845). In his first tenure, he showed himself conciliatory towards the native Christian population and the nakharar princes, but his second tenure was marked by the brutal suppression of several revolts by local Arab magnates, as well as the harsh treatment of the Christian population. As a result, when his re-appointment to the office was announced in 841, a rebellion broke out, forcing the Abbasid government to recall him immediately. Nevertheless, al-Wathiq assigned Arminiya to Khalid. The latter arrived in the province at the head of an army, and crushed any opposition. He died soon after at Dvin, where he was buried. He was succeeded by his son, Muhammad. His younger son Haytham ibn Khalid ruled in the family's stronghold of Shirvan, and was the first to claim the title of Shirvanshah.

Example Input: Question: What side was the Austro-Hungarian army on? Passage 1:In the 1980s, with the support of Swami Omanand Saraswati, he catalogued and evaluated metallic artefacts of the so-called Copper Hoard Culture by means of European methods and models for the first time, whereby numerous finds came to light especially in the Kanya Gurukul in Narela/Haryana. These artefacts appear to be non-functional objects, probably used in rituals or simply deposited in hoards, to judge from a lack of use-wear. Far away in Odisha, Yule published a find from a metals period cemetery in Sankarjang which may be the earliest musical instrument in India. He documented the early historic fortress at Sisupalgarh by means of a laser scanner, ground penetrating radar and a hand-held GPS receiver. Together with Corinna Borchert, Yule uncovered illegal building development within this nationally protected Mauryan site. From 2001-2004 in India, Yule documented so-called mud forts and other archaeological sites for the first time, especially in Odisha along the Mahanadi and Chhattisgarh. Images of his work especially in Odisha appear in the image bank heidICON.
 Passage 2:In 2003, Minnesota-raised singer, writer, and guitarist Craig Finn and New York City bartender and bassist Galen Polivka began talking about starting a band. Finn and lead guitarist Tad Kubler (both formerly of Lifter Puller) developed the idea of The Hold Steady when, while watching The Band concert film The Last Waltz, Finn asked Kubler, "Dude, why aren't there any bands like this anymore?" The Hold Steady's 2004 debut album Almost Killed Me, released on Frenchkiss Records, was a sleeper hit among music critics, reaching No. 31 in the Pazz & Jop critics poll that year, an achievement which Finn described as "like being nominated for an Oscar or something." In May 2005, they were the first rock band to grace the front page of The Village Voice in 15 years . They were Blender's 2006 "Band of the Year".
 Passage 3:Antoni Chruściel was born on 16 July 1895 in the village of Gniewczyna Łańcucka halfway between Łańcut and Przeworsk, to Andrzej Chruściel, a local farmer and the vogt of that village. In 1909, while still a student at a local gymnasium in Jarosław, Chruściel joined the secret scouting troop; he was also active in the Zarzewie movement. In 1914, after the outbreak of the First World War he moved to Lwów, where he joined the Eastern Legion. Soon afterwards, as a citizen of Austria-Hungary, he was drafted into the Austro-Hungarian Army. After graduating from an NCO school in May 1915 he served at various posts, including his service as a commanding officer of a company of the 90th Infantry Regiment. After the dissolution of Austria-Hungary and the chaos at the eastern front, Chruściel's regiment was the only unit in the entire Austro-Hungarian Army to return to the barracks as an organized entity and with arms. Few weeks later Chruściel, together with most of his unit, joined the newly formed Polish Army.
