Example Input: Question: What type of weapon did von Manteuffel and Karl Twesten use in their duel? Passage 1:Sabita Devi (1914–1965) was a Hindi film actress in Indian cinema. She is stated to be one of the "prominent" leading ladies of the "pioneering era" of Indian cinema along with Mehtab, Bibbo, Durga Khote, Gohar, Devika Rani and Seeta Devi. A Jewess by birth, she changed her name to find acceptability in Hindi cinema like the other Anglo-Indian and Jewish actresses of her time, Sulochana (Ruby Myers), Seeta Devi (Renee Smith), Madhuri (Beryl Claessen), and Manorama (Erin Daniels). After initially working with British Dominion Films Ltd., Calcutta, she shifted to Bombay and performed mainly in films produced by Sagar Movietone with her co-star in most films being Motilal. Some of the popular films with Motilal were Dr. Madhurika (1935) and Kulvadhu (1937) directed by Sarvottam Badami. Their first film together was Shaher Ka Jadoo (1934), which was also Motilal's debut film, and then Lagna Bandhan (1936) both directed by Kaliprasad Ghosh. She acted in Silver King (1935) with Motilal. It was an action film directed by C. M. Luhar, which became a "huge success".
 Passage 2:Promoted lieutenant-colonel in 1852, and colonel (and commanding officer of the 5th Uhlans) in 1853, Manteuffel was sent on important diplomatic missions to Vienna and St Petersburg. In 1857 he was promoted to major-general and chief of the Prussian Military Cabinet (the King's military advisers). He gave strong support to the Prince Regent's plans for the reorganization of the army. In 1861 he was violently attacked in a pamphlet by Karl Twesten (1820–1870), a Liberal leader, whom he had wounded in a duel, for which Manteuffel insisted on being briefly imprisoned. He was promoted to lieutenant-general for the coronation of William I on 18 October 1861 and saw active service in that rank in the Danish War of 1864, then at its conclusion was appointed civil and military governor of Schleswig. In the Austrian War of 1866 he first occupied Holstein and afterwards commanded a division under Vogel von Falkenstein in the Hanoverian campaign, then in July succeeded Vogel in command of the Army of the Main.
 Passage 3:Page attended the Okemos Montessori School (now called Montessori Radmoor) in Okemos, Michigan, from 1975 to 1979, and graduated from East Lansing High School in 1991. He attended Interlochen Center for the Arts as a saxophonist for two summers while in high school. Page holds a Bachelor of Science in computer engineering from the University of Michigan, with honors and a Master of Science in computer science from Stanford University. While at the University of Michigan, Page created an inkjet printer made of Lego bricks (literally a line plotter), after he thought it possible to print large posters cheaply with the use of inkjet cartridges—Page reverse-engineered the ink cartridge, and built all of the electronics and mechanics to drive it. Page served as the president of the Beta Epsilon chapter of the Eta Kappa Nu fraternity, and was a member of the 1993 "Maize & Blue" University of Michigan Solar Car team. As an undergraduate at the University of Michigan, he proposed that the school replace its bus system with a personal rapid transit system, which is essentially a driverless monorail with separate cars for every passenger. He also developed a business plan for a company that would use software to build a music synthesizer during this time.

Example Input: Question: How many years had the Ballet Russe de Monte Carlo been doing performances the year that Rudenko signed up with them? Passage 1:In 1938 Rudenko was signed up to the Ballet Russe de Monte Carlo, where, at 17, she was their youngest soloist. Her stage name was Lubov Roudenko, and she was also popularly known as "Spitfire Lu-Lu." She had a can-can sequence in the 1938 ballet Gaîté Parisienne choreographed specially for her by Léonide Massine. She would later reprise this role in the 1941 Oscar-nominated short film The Gay Parisian. Whilst with the Ballet Russes, Rudenko was the subject of several drawings by Henri Matisse in 1939. Four of his portrait sketches of her are now in the Fogg Museum. Matisse also made a drawing of Rudenko in the ballet  Rouge et Noir. While on tour with the Ballet Russe, Rudenko performed the role of the Cowgirl in the 1942 ballet Rodeo until the tour reached New York and Agnes de Mille, the original choreographer, reclaimed the role for herself. Disappointed by this, Rudenko quit the Ballet Russes, and took a better-paid job performing in a Broadway production of The Merry Widow. This production launched at the Majestic Theatre on 4 August 1943, with Rudenko and James Starbuck leading the character dances, including a comic polka and a can-can number. After this, Rudenko played Grisette in Nellie Bly, a short-lived 1946 musical based on the life of Nellie Bly, and then became lead dancer for the 1946-49 Broadway production of Annie Get Your Gun, but following a knee injury, decided to pursue a career in fashion design. She continued performing until 1951, appearing in the 1950-51 Olsen and Johnson revue Pardon our French.
 Passage 2:Bhutia has had limited opportunities in playing overseas. On 30 September 1999, he travelled overseas to play for Bury in Greater Manchester, England. He became only the second Indian footballer to play professionally in Europe after Mohammed Salim. By penning a three-year contract he also became the first Indian footballer to sign for a European club. This followed unsuccessful trials for Bhutia with Fulham, West Bromwich Albion and Aston Villa. He had difficulty obtaining a visa and could not make his debut, until 3 October 1999 against Cardiff City. In that match, he came on as a substitute for Ian Lawson and played a part in Bury's second goal, which was scored by Darren Bullock after Bhutia's volley was deflected into his path. On 15 April 2000, he scored his first goal in the English league in the game against Chesterfield. A recurring knee injury limited him to only three games in his final season at Bury, and he was released after the club was placed in administration. His final appearance was a 3–0 defeat to Swindon Town on 27 August 2001.
 Passage 3:Of the 62 flying fox species evaluated by the IUCN as of 2018, 3 are considered critically endangered: the Aru flying fox, Livingstone's fruit bat, and the Vanikoro flying fox. Another 7 species are listed as endangered; 20 are listed as vulnerable, 6 as near threatened, 14 as least concern, and 8 as data deficient. A further 4 are listed as extinct: the dusky flying fox, the large Palau flying fox, the small Mauritian flying fox, and the Guam flying fox. Over half of the species are threatened today with extinction, and in particular in the Pacific, a number of species have died out as a result of hunting, deforestation, and predation by invasive species. Six flying fox species are believed to have gone extinct from 1864 to 2014: the Guam, large Palau, small Mauritian, dusky, large Samoan, and the small Samoan flying foxes.

Example Input: Question: Which of the two who collaborated together in the Dark Knight Trilogy films is older? Passage 1:Calvin Coolidge (born John Calvin Coolidge Jr.; ; July 4, 1872 – January 5, 1933) was an American politician and lawyer who served as the 30th president of the United States from 1923 to 1929. A Republican lawyer from New England, born in Vermont, Coolidge worked his way up the ladder of Massachusetts state politics, eventually becoming governor of Massachusetts. His response to the Boston Police Strike of 1919 thrust him into the national spotlight and gave him a reputation as a man of decisive action. The next year, he was elected vice president of the United States, and he succeeded to the presidency upon the sudden death of Warren G. Harding in 1923. Elected in his own right in 1924, he gained a reputation as a small government conservative and also as a man who said very little and had a rather dry sense of humor.
 Passage 2:Michael Caine is an English actor who has appeared in over 130 films and has had multiple television appearances. Caine's acting career began in the 1950s, when he was cast in many small, often uncredited roles in British films. Caine gained recognition as one of the most famous actors of the 1960s through his breakthrough role in the film Zulu (1964). He then portrayed spy Harry Palmer in the films The Ipcress File (1965), Funeral in Berlin (1966) and Billion Dollar Brain (1967). He also had starring roles in The Italian Job and Battle of Britain (both 1969). His role in Sleuth (1972) led him to an Academy Award for Best Actor nomination. Caine has won a Best Supporting Actor Oscar for the films Hannah and Her Sisters (1986) and The Cider House Rules (1999). More recently, Caine has gained a new following through his collaborations with British-American filmmaker Christopher Nolan in the Dark Knight Trilogy films, as well as Inception (2010) and Interstellar (2014).
 Passage 3:Yakov Hanecki was born in Warsaw, then in the Russian Empire, the son of Stanislav von Fürstenberg, a beer manufacturer of German descent, who had adopted Poland as his homeland. In 1896 he joined the Social Democracy of the Kingdom of Poland (SDKP - later the Social Democracy of the Kingdom of Poland and Lithuania (SDKPiL)) led by Rosa Luxemburg and her lover, Leo Jogiches. He moved to Germany in 1901 and studied in rapid succession at Berlin, Heidelberg, and Zurich universities. From 1902, he was a professional revolutionary, normally based in Cracow, under Austrian rule, organising the transport of illegal literature across the Russian border. In August 1903, as a member of the Main Administration of the SDKPiL, he was one of two Polish delegates to the Second Congress of the Russian Social Democratic Labour Party (RSDLP) in Brussels. The Congress later adjourned to London, under pressure from the Belgian police, and there the RSDLP split into its Bolshevik and Menshevik factions, but Hanecki and the other Polish delegate, Adolf Warski, did not make the journey to London, having failed to agree terms on which the RSDLP and SDKPiL could collaborate.
