Example input: Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage 1: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lô during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,
. Passage 2: John Ford (1894–1973) was an American film director whose career spanned from 1913 to 1971. During this time he directed more than 140 films. Born in Maine, Ford entered the filmmaking industry shortly after graduating from high school with the help of his older brother, Francis Ford, who had established himself as a leading man and director for Universal Studios. After working as an actor, assistant director, stuntman, and prop man – often for his brother – Universal gave Ford the opportunity to direct in 1917. Initially working in short films, he quickly moved into features, largely with Harry Carey as his star. In 1920 Ford left Universal and began working for the Fox Film Corporation. During the next ten years he directed more than 30 films, including the westerns The Iron Horse (1924) and 3 Bad Men (1926), both starring George O'Brien, the war drama Four Sons and the Irish romantic drama Hangman's House (both 1928 and both starring Victor McLaglen). In the same year of these last two films, Ford directed his first all-talking film, the short Napoleon's Barber. The following year he directed his first all-talking feature, The Black Watch.
. Passage 3: Since the late 1970s, the central part of NYU is its Washington Square campus in the heart of Greenwich Village. Despite being public property, and expanding the Fifth Avenue axis into Washington Square Park, the Washington Square Arch is the unofficial symbol of NYU. Until 2008, NYU's commencement ceremony was held in Washington Square Park. However, due to space constraints, ceremonies are now held at the Yankee Stadium. Important facilities at Washington Square are the Elmer Holmes Bobst Library, designed by Philip Johnson and Richard Foster, who also designed several other structures, such as Tisch Hall, Meyer Hall, and the Hagop Kevorkian Center. When designing these buildings Johnson and Foster also set up a master plan for a complete redesign of the NYU Washington Square campus. However, it was never implemented. Other historic buildings include the Silver Center (formerly known as "Main building"); the Brown Building of Science; Judson Hall, which houses the King Juan Carlos I of Spain Center; Vanderbilt Hall, the historic townhouse row on Washington Square North; The Grey Art Gallery at 100 Washington Square East, housing the New York University art collection and featuring museum quality exhibitions; the Kaufman Management Center; and the Torch Club – the NYU dining and club facility for alumni, faculty, and administrators. Just a block south of Washington Square is NYU's Washington Square Village, housing graduate students and junior and senior faculty residences in the Silver Towers, designed by I. M. Pei, where an enlargement of Picasso's sculpture Bust of Sylvette (1934) is displayed.

Q: Question: How old was the Ottoman commander during the siege when the Russian Army achieved victory at Uzunahmet? Passage 1:On 4 November 1877 the Russian army achieved a victory at Uzunahmet, having inflicted heavy casualties on the Turks, which included 3,000 killed and wounded, 1,000 prisoners and 42 artillery pieces left by the panicked gunners, with a loss of only 1,200 men. Although the Turkish troops ceased resistance and were fleeing in disarray, with 4,000 of them deserting the army, a part of their infantry maintained order and retreated to the well-fortified position in Erzurum with 14 guns. The Russians, being miles away and exhausted by the battle, did not chase them and therefore missed a chance to capture Erzurum on the heels of the fleeing enemy. Having developed a plan of assault on the stronghold, the Russian army advanced under the cover of night, but had difficulties of movement control in the dark. A part of their troops from the 153th Infantry Regiment mistook their direction and captured one of the redoubts, Azizieh, all by themselves, without help from the rest of the army, but had to leave it due to the lack of support. All the three Turkish battalions stationed in the Azizieh redoubt were routed, numbering 1,600, whereas the Russians lost 400 or 600 men in this battle. After the Russians left Azizieh, the Turks made an attempt to counterattack them, but were successfully driven back. As the works of Erzurum were too strong to be taken by assault, the siege park was needed at Kars and in the following days the weather set in with a snowstorm, the Russians decided to withdraw their army and instead attack Kars, which they succeeded in capturing. Ahmed Muhtar Pasha, the Ottoman commander during the siege, requested reinforcements from Istanbul and was receiving them all through November. After epidemics broke out, he withdrew his forces to Bayburt for the remainder of the war. Muhtar Pasha was awarded the title Ghazi for his role in the defence of Erzurum, Gedikler and Yahniler. The city of Erzurum would be captured by the Russians a few months later, on 8 February 1878.
 Passage 2:José Efraín Ríos Montt (; June 16, 1926 – April 1, 2018) was a Guatemalan general, politician, and war criminal who served as President of Guatemala. Born in Huehuetenango, he was a dictator who took power as a result of a coup d'état on March 23, 1982. He was overthrown by his defense minister, Óscar Humberto Mejía Victores, in another coup d'état on August 8, 1983. In the 2003 presidential elections, Ríos Montt unsuccessfully ran as the candidate of the Guatemalan Republican Front (FRG). In 2007 he returned to public office as a member of Congress, thereby gaining prosecutorial immunity. He was protected from a pair of long-running lawsuits alleging war crimes against him and a number of his former ministers and counselors during their term in the presidential palace in 1982–83. His immunity ended on January 14, 2012, with the end of his term in legislative office. On January 26, 2012, he appeared in court in Guatemala and was formally indicted for genocide and crimes against humanity.
 Passage 3:In India, the state governments are the level of governments below the Union government. India is a Sovereign Socialist Secular Democratic Republic with a Parliamentary system of government. The Republic is governed in terms of the Constitution of India. Sovereignty is shared between the union and the state government, but the union government is given greater powers. The President is the constitutional head Executive of the State. Real executive power vests in a Union Council of Ministers with the Prime Minister as head of government. The States resembles the federal system. In the states, the Governor is the head of Executive, but real executive power vests with the Chief Minister who heads the Council of Ministers. The judicial setup of the country is headed by the Chief Justice of India at federal level, who presides over one of the largest judicial apparatus dispensing criminal, civil and all other forms of litigation, and Chief Justices of the High Courts at state level. The government head of its legal wing is the Attorney General of India at federal level and Advocate General at state level.
