Example Input: Question: How many years did the war last for which the 60th anniversary of its end was celebrated by the 2005 European Stars' Tour? Passage 1:Erdem Moralioglu is a Canadian and Turkish fashion designer. He was born in Montreal, Quebec, Canada to a Turkish father and an English mother (Nee Jeavons) and grew up between Montreal and Birmingham, England. A graduate of Marianopolis College, he earned a B.A. in fashion from Ryerson University in Toronto, Ontario, Canada and then worked as an intern for Vivienne Westwood.

Upon receiving his master's degree in 2003, he went on to close the 2003 RCA show with his graduate collection. He then moved to New York where he worked alongside Diane von Fürstenberg before relocating back to London to launch his own label, ERDEM, in 2005.
 Passage 2:Kalivodová first worked with the Prague State Opera in 2001, as part of the Pounding on the Iron Curtain project, a production of two operas by Vladimir Wimmer.

Example Input: Question: How old was the military engineer who scouted around Leith during the siege? Passage 1:After completing his secondary education at Highgate School, he attended King's College, Cambridge, earning his PhD in theoretical (high-energy) particle physics in 1971. After brief post-doc positions at SLAC and Caltech, he went to CERN and has held an indefinite contract there since 1978. He was awarded the Maxwell Medal and the Paul Dirac Prize by the Institute of Physics in 1982 and 2005 respectively, and is an Elected Fellow of the Royal Society of London since 1985 and of the Institute of Physics since 1991. He was awarded an Honorary Doctorate from the University of Southampton, and twice won the First Award in the Gravity Research Foundation essay competition (in 1999 and 2005). He is also Honorary Doctor at Uppsala University.
 Passage 2:The English King Henry VIII, angered by the Scots reneging on the initial agreement, made war on Scotland in 1544–1549, a period which the writer Sir Walter Scott later christened the "Rough Wooing". In May 1544 an English army landed at Granton and captured Leith to land heavy artillery for an assault on Edinburgh Castle, but withdrew after burning the town and the Palace of Holyrood over three days. Three years later, following another English invasion and victory at Pinkie Cleugh in 1547, the English attempted to establish a "pale" within Scotland. Leith was of prime strategic importance because of its vital role as Edinburgh's port, handling its foreign trade and essential supplies. The English arrived in Leith on 11 September 1547 and camped on Leith Links. The military engineer Richard Lee scouted around the town on 12 September looking to see if it could be made defensible. On 14 September the English began digging a trench on the south-east side of Leith near the Firth of Forth. William Patten wrote that the work was done as much for exercise as for defence, since the army only stayed for five days.
 Passage 3:Pieter van Laer (1599 – c. 1642) was a Dutch Golden Age painter of genre scenes, active for over a decade in Rome, where his nickname was Il Bamboccio. Artists working in his style, who often painted just such scenes of everyday life as Pliny lists, became known as the Bamboccianti, painters in Bamboccio's manner. Peiraikos is often mentioned in the controversies over the Bamboccianti, for example by Salvator Rosa in his Satires, and later by the Dutch biographer of artists, Samuel Dirksz van Hoogstraten in his Inleyding tot de Hooge Schoole der Schilderkonst (Introduction to the Academy of Painting), Rotterdam 1678. As genre painting became an important element of Dutch Golden Age painting, Peiraikos was used to provide classical precedent for such work, in the relatively few discussions of the appropriateness of such art by Karel van Mander in his Schilder-boeck (1604) and Arnold Houbraken in his The Great Theatre of Dutch Painters (1718–1719). Having originally been often rather cheap, by the late 17th century the best Dutch genre scenes became sought after by collectors across Europe at very high prices, a development following Pliny's account of Peiraikos that was bemoaned by Lessing in his Laocoon (1763), mentioning Dutch painting specifically.

Example Input: Question: Were all the 500cc motorcycles that Mackenzie raced on made by Japanese manufacturers? Passage 1:Parish began his career at Aston Villa, where he progressed through the club's Academy. He made his professional debut away from the club on loan at League Two side Lincoln City in 2011, before a short loan at Cardiff City where he made no appearances. He joined Cardiff on a permanent basis in January 2012, before being loaned out to Wycombe Wanderers later the same year. He was released by the club in 2013, again failing to make a first-team appearance. He joined Bristol City, where he went on to make 19 league appearances, but again found himself out on loan, on this occasion to Newport County. He later joined Blackpool for one season, and then played for Colchester United for one season, before joining Accrington Stanley. He then signed for Dundee where he spent two seasons.
 Passage 2:Mackenzie, who hails from Fankerton, near Denny, Stirlingshire; won the British Superbike Championship three times from 1996 to 1998 with the Rob McElnea-run Yamaha team, and the British 250cc and 350cc titles twice earlier in his career. He had a long career in the Grand Prix motorcycle racing circuit, debuting in 1984 in the 250cc class. He moved up to the 500cc class in 1986 on a Suzuki before spells on Honda and Yamaha motorcycles. He was 4th in the championship in 1990, and finished in the top 10 in the championship on five other occasions. His final racing season was the 2000 British Superbike series, although he did a farewell one-off at Knockhill in 2001 and stood in for the injured Yukio Kagayama at Donington Park in 2003.
 Passage 3:Assert was then matched against older horses for the first time in Britain's most prestigious weight-for-age race, the King George VI and Queen Elizabeth Stakes over one and a half miles at Ascot Racecourse on 24 July. He started the 10/11 favourite ahead of his half-brother Bikala who had beaten a strong field in the Prix Ganay on his previous start. The other main contenders were Kalaglow, Height of Fashion and Glint of Gold. Assert went past Bikala on the turn into the straight and held off a strong challenge from Glint of Gold, but was caught inside the final furlong and beaten a neck by Kalaglow. On 17 August Assert was ridden by Pat Eddery in the eleventh running of the Benson and Hedges Gold Cup over ten and a half furlongs at York Racecourse. Starting the 4/5 favourite against six British-trained opponents, he took the lead from the start and pulled clear in the straight vo win easily by six lengths from Norwick. A month later, Assert started the 1/4 favourite for the Joe McGrath Memorial Stakes over ten furlongs. With Roche back in the saddle, he went eight lengths clear in the straight before being eased down to win by three lengths from Kind of Hush. Timeform described the race as being "little more than an exercise gallop" for the winner. On 3 October, Assert started 5/2 favourite for the Prix de l'Arc de Triomphe on very soft ground at Longchamp Racecourse. He was well-positioned turning into the straight but dropped away in the closing stage and finished eleventh of the seventeen runners behind Akiyda.
