Example Input: Question: How old was Burns when she played as Jessie Owens? Passage 1:Within weeks, many Americans could recite favorite lines from the record, including "the rubber schwan [swan] is mine", and "move ahead...with great vigah [vigor]", the latter lampooning the President's own words. The album poked fun at Kennedy's PT-109 history; the rocking chairs he used for his painful back; the Kennedy clan's well-known athleticism, football games and family togetherness; children in the White House; and Jackie Kennedy's soft-spoken nature and her redecoration of the White House; and many other bits of knowledge that the public was eager to consume. Kennedy himself was said to have given copies of the albums as Christmas gifts, and once greeted a Democratic National Committee group by saying, "Vaughn Meader was busy tonight, so I came myself." According to UPI reporter Merriman Smith, during a Cabinet meeting Kennedy played the entire record for everyone. At one press conference, Kennedy was asked if the album had produced "annoyment (sic) or enjoyment." He jokingly responded, "I listened to Mr. Meader's record and, frankly, I thought it sounded more like Teddy than it did me. So, now he's annoyed."
 Passage 2:From 1998 to 2001, Burns starred in Baywatch as the character Jessie Owens. In 2001, she appeared as Vicki Vale in one of several "Batman" commercials for OnStar, opposite Bruce Thomas's Batman. Burns hosted NBC's Dog Eat Dog from June 2002 to August 2003 and was nominated for a Teen Choice Award. Burns starred in North Shore, a prime-time soap opera that ran for 21 episodes in 2004 and 2005. In 2006, she starred in the WB series Pepper Dennis playing Kathy Dinkle. In 2009, Burns appeared in the first twelve episodes of the updated Melrose Place playing Vanessa, the most recent wife of Dr. Michael Mancini (Thomas Calabro) and mother of his older son's five-year-old son, Noah. Burns was given the chance to participate in the first season of the ABC celebrity diving reality competition Splash but turned it down because of an injury she had received when diving a few years before.
 Passage 3:Prior to the 2004–05 season, the Lakers traded Payton and Rick Fox to the Boston Celtics for center Chris Mihm, small forward Jumaine Jones and point guard Chucky Atkins. While Payton expressed displeasure with the trade, he ultimately did report to Boston and began the 2004–05 season as the Celtics' starting point guard. On February 24, 2005 Payton was traded to the Atlanta Hawks in a deal that brought former Celtic Antoine Walker back to Boston. The Hawks then waived Payton immediately following the trade, and he returned a week later to Boston as a free agent. Payton started all 77 games he played for Boston and averaged 11.3 points per game and 6.1 assists as the Celtics won the Atlantic Division before losing in the first round to the Indiana Pacers.

 Passage 2:Merivale was the second son of John Herman Merivale (1770–1844) and Louisa Heath Drury, daughter of Joseph Drury, headmaster of Harrow. He was educated at Harrow School under George Butler from 1818 to 1824, where his chief schoolfriends were Charles Wordsworth and Richard Chenevix Trench. He took part in the Eton versus Harrow cricket match in 1824. In 1824 he was offered a post in the Indian civil service, and went for a short time to Haileybury College, where he did well in Oriental languages. Deciding against an Indian career, he went up to St John's College, Cambridge in 1826. Among other distinctions he came out as fourth classic in 1830, and in 1833 was elected fellow of St John's. He was a member of the Apostles' Club, his fellow-members including Tennyson, A. H. Hallam, Monckton Milnes, W. H. Thompson, Trench and James Spedding. Merivale was the main protagonist on the Cambridge side in instigating the Oxford and Cambridge Boat Race held at Henley on Thames in 1829. He rowed at number four in the Cambridge boat in the race which Oxford won.

Example Input: Question: In what year did Ostashenko's country join the first world war? Passage 1:Born Michael Sean Brotherton in Granite City, Illinois, he grew up in St. Louis, Missouri where he graduated from the John Burroughs School in 1986. He then headed south for college attending Rice University, from where he graduated Magna Cum Laude in 1990 with a BS in electrical engineering.

From 1996 to 1999 he was a postdoctoral fellow at the Institute of Geophysics and Planetary Physics at Lawrence Livermore National Laboratory working primarily with Wil van Breguel and Robert Becker on the Very Large Array's FIRST survey related projects. From 1999-2002, he was a postdoctoral researcher at the National Optical Astronomy Observatory and FUSE Science Team Associate working with Richard Green in Tucson, Arizona. He is currently a tenured professor of astronomy at the University of Wyoming at Laramie, where he's been since 2002.
 Passage 2:The Battle of Lexington and Concord was the first conflict in the American Revolutionary War. On April 19, 1775, a force of British Army regulars marched from Boston to Concord to capture a cache of arms that was reportedly stored in the town. Forewarned by Samuel Prescott (who had received the news from Paul Revere), the colonists mustered in opposition. Following an early-morning skirmish at Lexington, where the first shots of the battle were fired, the British expedition under the command of Lt. Col. Francis Smith advanced to Concord. There, colonists from Concord and surrounding towns (notably a highly drilled company from Acton led by Isaac Davis) repulsed a British detachment at the Old North Bridge and forced the British troops to retreat. Subsequently, militia arriving from across the region harried the British troops on their return to Boston, culminating in the Siege of Boston and the outbreak of the war.
 Passage 3:Ostashenko was born on 19 June 1896 in the village of Bolshaya Lyubshchina, Yanovichskoy volost, Vitebsky Uyezd, Vitebsk Governorate to a peasant family. He graduated from four grades at a gymnasium. During World War I, he was mobilized for military service on 7 August 1915, being sent to the 4th Company of the Reserve Battalion of the Petrograd Lifeguard Regiment in Petrograd. With the battalion, he fought with the Southwestern Front between July 1916 and February 1917, then returned to Petrograd before being demobilized on 13 March 1918. In July, he volunteered for the Red Army, serving in the Vitebsky Uyezd military commissariat as a clerk and instructor organizer. From May 1919 Ostashenko served as a Red Army man and political soldier – a Communist mobilized to conduct political work in the army – in the march battalion of the Vitebsk Reserve Regiment. From July he served as an assistant platoon commander in the 84th Rifle Regiment of the 10th Rifle Division, which fought against the Northwestern Army near Petrograd as part of the 15th Army of the Western Front. He entered the Smolensk Commanders' Infantry Courses in November and upon graduation in June 1920 became a platoon commander in the Rzhev-based 2nd Reserve Regiment. This assignment proved to be brief and a month later, Ostashenko became adjutant of the 4th Landing Detachment for armored trains with the Western Front. He fought with the detachment, which provided landing parties for armored trains, in the Polish–Soviet War and was wounded twice.
