In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.

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: In which country was MS Al Andalus Express built? Passage 1:MS Al Andalus Express (formerly Nord Pas-de-Calais) is a freight ferry owned by Eurotunnel and operated by FRS Iberia/Maroc. She was built in 1987 by Chantiers du Nord et de la Mediterranee, Dunkirk (Yard No 325) for Societe Nationale des Chemin de Fer Francais (SNCF), Paris as a multi-purpose passenger and roll-on roll-off ferry for lorries and railway vehicles. After the introduction of Eurotunnel there was no need for a train ferry, so SNCF was losing money running her. She was acquired by SNAT and Stena Sealink in 1989, which operated the Nord Pas-de-Calais until 31 December 1995. From 1 January 1996 SNAT operated as SeaFrance. The vessel was renamed SeaFrance Nord Pas-de-Calais. SeaFrance operated until November 2011, and was liquidated on 9 January 2012. Eurotunnel won the bid for the three of the former SeaFrance vessels the original name of the vessel was restored, dropping the SeaFrance prefix. MyFerryLink started running on 20 August 2012, although Nord Pas-de-Calais joined in November 2012 following a refit. Following MyFerryLink's cessation of operations, mostly cited due to financial issues, the ferry was used directly by Eurotunnel to carry hazmat cargoes that are not allowed on regular train services.
 Passage 2:Lange was born in Warsaw into the patriotic Jewish family of Henryk Lange (1815–1884) and Zofia née Eisenbaum (1832–1897). His father took part in the November Uprising against the Russian Partition of Poland. He was an admirerer of Romantic literature and its ideals. Antoni Lange enrolled at Warsaw University but around 1880 he was expelled for his patriotic activity by the Tsarist namiestnik Apuchtin who ruled the university at that time. He supported himself financially as a tutor but also published poetry under the pen-names Napierski and Antoni Wrzesień. He decided to study in Paris where he encountered new trends in literature, philosophy and art. In France he became familiar with the theories of Jean Martin Charcot, as well as Spiritualism, parapsychology, the philosophy of Arthur Schopenhauer and Friedrich Nietzsche, oriental religions, European and Eastern literature and modern literary criticism. He took part in the literary meetings of Stéphane Mallarmé.
 Passage 3:Bulgaria was focused on actions in Thrace and Macedonia. It deployed its main force in Thrace, forming three armies. The First Army (79,370 men), under general Vasil Kutinchev with three infantry divisions, was deployed to the south of Yambol, with direction of operations along the Tundzha river. The Second Army (122,748 men), under general Nikola Ivanov, with two infantry divisions and one infantry brigade, was deployed west of the First and was assigned to capture the strong fortress of Adrianople (Edirne). According to the plans, the Third Army (94,884 men), under general Radko Dimitriev, was deployed east of and behind the First, and was covered by the cavalry division hiding it from Turkish view. The Third Army had three infantry divisions and was assigned to cross the Stranja mountain and to take the fortress of Kirk Kilisse (Kırklareli). The 2nd (49,180) and 7th (48,523 men) divisions were assigned independent roles, operating in Western Thrace and Eastern Macedonia respectively.

Example Input: Question: What were the combined ages of Nigel Patrick and Jack Warner the year that they were staring in a movie that Brian Wilde had an uncredited role as a small-time crook? Passage 1:He had an early uncredited role as a small-time crook in the 1954 film Forbidden Cargo, starring Jack Warner and Nigel Patrick, and a small but significant and dramatic part in the horror film Night of the Demon (1957). His early television work included the series The Love of Mike (1960) and supporting Tony Hancock in episodes of his ATV series in 1963. Wilde also played Detective Superintendent Halcro in a series of two-part thrillers about undercover Scotland Yard officers, The Men from Room Thirteen (BBC, 1959–61). He had minor roles in films such as Life for Ruth (1962), The Bargee (1964), The Jokers (1967) and Carry On Doctor (1967), and on television in Room at the Bottom (1966–67) as Mr Salisbury. His first major television success was in 1970 as refuse depot manager "Bloody Delilah" in the ITV sitcom The Dustbinmen. He showed his sinister side as the mischievous magician Mr Peacock in the children's drama series Ace of Wands between 1970 and 1972. That year he starred as a murderer in The Uninvited, an episode of the BBC's supernatural thriller series Out of the Unknown. Also in 1971, in the television drama Elizabeth R, Wilde played the efficient, merciless 'rackmaster' Richard Topcliffe, who was charged with the torture of prisoners in the Tower of London. He played a character in the 1970s British children's series The Ghosts of Motley Hall, by Richard Carpenter.
 Passage 2:The role of the deoxyriboside form of 8-oxoguanine, 8-oxo-2'-deoxyguanosine (abbreviated 8-oxo-dG or 8-OHdG) in cancer and aging also applies to 8-oxoguanine. Oxoguanine glycosylase is employed in the removal of 8-oxoguanine from DNA by the process of base excision repair. As described in oxoguanine glycosylase, deficient expression of this enzyme causes 8-oxoguanine to accumulate in DNA. This accumulation may then lead upon replication of DNA to mutations including some that contribute to carcinogenesis. 8-oxoguanine is usually formed by the interaction of reactive oxygen species (ROS) with the guanine base in DNA under conditions of oxidative stress; as noted in the article about them, such species may have a role in aging and male infertility, and 8-oxoguanine can be used to measure such stress.
 Passage 3:Achaea was founded in 1205 by William of Champlitte and Geoffrey I of Villehardouin, who undertook to conquer the Peloponnese on behalf of Boniface of Montferrat, King of Thessalonica. With a force of no more than 100 knights and 500 foot soldiers, they took Achaea and Elis, and after defeating the local Greeks in the Battle of the Olive Grove of Koundouros, became masters of the Morea. The victory was decisive, and after the battle all resistance from the locals was limited to a few forts, that continued to hold out. The fort of Araklovon in Elis, was defended by Doxapatres Boutsaras and withstood the attacks until 1213, when the garrison finally surrendered. The fort of Monemvasia, and the castles of Argos, Nauplia and Corinth under Leo Sgouros held out until his suicide in 1208. By 1212, these too had been conquered, and organized as the lordship of Argos and Nauplia, and only Monemvasia continued to hold out until 1248. William of Champlitte ruled Achaea until he departed for France to assume an inheritance, but died on the way there in 1209. He was succeeded by Geoffrey I of Villehardouin, who ruled until his own death in 1219.
