Example Input: Question: How many years had the station been on air when it switched its call sign to WGVC? Passage 1:The station became WQXL in 1962 after the station was sold to the Belk Broadcasting Company. The WOIC call sign resurfaced that same year on 1320 AM (now WISW). WQXL originally aired a Big Band format, which eventually gave way to a Top 40 format by the end of the decade. However it was handicapped with a daytime-only signal and was unsuccessful in competing against format rivals 1230 WNOK and 1400 WCOS, which each had full-time signals. Probably its most notable personality was Mackie "Cactus" Quave who had worked at 560 WIS (now WVOC) and had a successful kids TV show on NBC Network affiliate Channel 10 WIS-TV. WQXL switched to country music in the summer of 1966, but again was bested by rival 620 WCAY (now WGCV). In 1973, the station switched to religious programming and eventually adopted a Contemporary Christian format.
 Passage 2:Dominguín was also a socialite, having friends like Pablo Picasso and romances with the American actress Ava Gardner and the fashion model China Machado. In 1955, he married actress Lucia Bosé, who gave birth to his son Miguel Bosé, a Grammy-award winning singer. He also occasionally appeared in films, predominantly playing himself in cameo roles, in movies such as Around the World in 80 Days (1956), Testament of Orpheus (1960), and The Picasso Summer (1969). In 1959, he and his brother-in-law, Antonio Ordóñez, engaged in a bullfighting rivalry that was chronicled by Ernest Hemingway in his book, The Dangerous Summer. Ordóñez won. In 1964 he was a mystery guest on the US TV show What's My Line?.
 Passage 3:The ascot is descended from the earlier type of cravat widespread in the early 19th century, most notably during the age of Beau Brummell, made of heavily starched linen and elaborately tied around the neck. Later in the 1880s, amongst the upper-middle-class in Europe men began to wear a more loosely tied version for formal daytime events with daytime full dress in frock coats or with morning coats. It remains a feature of morning dress for weddings today. The Royal Ascot race meeting at the Ascot Racecourse gave the ascot its name, although such dress cravats were no longer worn with morning dress at the Royal Ascot races by the Edwardian era. The ascot was still commonly worn for business with morning dress in the late 19th and very early 20th centuries.

Example Input: Question: What country is Gasaton Cros' birthplace now found? Passage 1:The Chronicon Angliae Petriburgense is a 14th-century chronicle written in Medieval Latin at Peterborough Abbey, England, covering events from 604 to 1368, although the original manuscript ends with an entry for 868, and the remainder was added in the 17th century. It survives as part of a composite manuscript volume held at the British Library with the mark Cotton Claudius A.v, in which it appears on folios 2–45. An edition of the Chronicon was published in 1723 by Joseph Sparke, in a collection of English histories by various writers. According to John Allen Giles, in the preface to his own edition published by the Caxton Society in 1845, the Chronicon was attributed by both Simon Patrick and Henry Wharton to John of Caleto (or "Caux"), who was an abbot of Peterborough (1250–1262). Giles reported a marginal note in the manuscript making a similar attribution, besides a similar note at the beginning of the manuscript stating that it belonged to Peterborough Abbey. However, Giles observed that this manuscript attribution was "comparatively modern", and regarded the chronicle's author as unknown. In Giles's view, the Chronicon is "extremely valuable both on account of the numerous facts which it contains, and for the [700 years] which it embraces."
 Passage 2:Born in Berlin to the distinguished Prussian military family von Bülow, originally from Mecklenburg, he enlisted in the Prussian Army and was assigned to the 2nd Guards regiment of infantry in 1864. He saw action during the Austro-Prussian War in 1866 and gained distinction at Königgrätz. Von Bülow served through the Franco-Prussian War of 1870 as a junior officer, winning the Iron Cross Second Class. A Captain of the German General Staff in 1877, von Bülow was promoted to Colonel and assigned to the 9th Guards Regiment in 1894. In 1897, von Bülow was a major-general and became director of the Central Department in the German War Ministry. In 1900 he was promoted to lieutenant-general and in 1901 was appointed general commanding the Guards Division. He was Commander of the German III Corps from 1903 until his appointment as Inspector of the German 3rd Army in 1912.
 Passage 3:Colonel Marie Augstin Gaston Cros (known as Gaston Cros) (6 October 1861 – 10 May 1915) was a French army officer and archaeologist. He was born in Alsace and was displaced when that territory was incorporated into the German Empire. He joined the French Army as a lieutenant and saw action in Tonkin before spending several years surveying in Tunisia, receiving the honours of membership of Vietnamese and Tunisian orders and appointment as a chevalier of the Legion of Honour. In 1901 Cros was appointed head of the French archaeological expedition to Girsu, Iraq to continue the work of Ernest de Sarzec. His work over the next five years included the tracing of the thick city wall and for his work there received a letter of commendation from Gaston Doumergue, the Minister of Fine Arts, and the award of the Golden Palms of the Ordre des Palmes Académiques. Promoted to lieutenant-colonel, Cros served in the French protectorate of Morocco from 1913, seeing action in the Zaian War.

In the 1920s he worked in the field of literary criticism and psychology as a professor at the University of Turku and is said to have been the first to introduce gestalt psychology to Finland. He was a part of the cultural circles of the time with the likes of Jean Sibelius and Frans Eemil Sillanpää. In 1916 he married the painter Anna Lovisa Snellman, who was granddaughter of Johan Vilhelm Snellman. He had University positions as lecturer in Helsinki and professor in Turku, and in 1930 he was appointed professor of theoretical philosophy at the University of Helsinki. In the 1930s, Kaila was closely associated with the Vienna Circle.
 Passage 3:Port is produced from grapes grown and processed in the demarcated Douro region. The wine produced is then fortified by the addition of a neutral grape spirit known as aguardente to stop the fermentation, leaving residual sugar in the wine, and to boost the alcohol content. The fortification spirit is sometimes referred to as brandy but it bears little resemblance to commercial brandies. The wine is then stored and aged, often in barrels stored in a Lodge (meaning "cellar") as is the case in Vila Nova de Gaia, before being bottled. The wine received its name, "port", in the later half of the 17th century from the seaport city of Porto at the mouth of the Douro River, where much of the product was brought to market or for export to other countries in Europe. The Douro valley where port wine is produced was defined and established as a protected region, and the name Douro thus an official appellation, in 1756, making it the third oldest, after Chianti (1716) and Tokaj (1730).
