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: What is the birthdate of the person who Juan David García Bacca criticized causing him to go into exile? Passage 1:On 26 March 2015, it was announced that Treweek was to become the next Bishop of Gloucester, the diocesan bishop of the Diocese of Gloucester. Though there had been two women appointed bishops previously in the Church of England, she was the first woman to be appointed a diocesan bishop, rather than as a suffragan bishop. She was the first woman to become a bishop in the Province of Canterbury, jointly with Sarah Mullally, Bishop of Crediton. On 15 June 2015, her election was confirmed during a sitting of the Arches Court of Canterbury at St Mary-le-Bow, City of London. At this point, she legally became the Bishop of Gloucester. On 22 July 2015, she was consecrated a bishop by Justin Welby, the Archbishop of Canterbury, during a ceremony at Canterbury Cathedral. She and Sarah Mullally (later Bishop of London) were the first women to be ordained as bishops at Canterbury Cathedral. On 19 September, she was installed at Gloucester Cathedral as the 41st Bishop of Gloucester.
 Passage 2:During the Second World War Hakewill-Smith initially served as Commanding Officer (CO) of the 5th Battalion, Devonshire Regiment, for several months from May 1940 and from September that year, as the CO of the 4th/5th Battalion, Royal Scots Fusiliers, as an acting lieutenant colonel. He was promoted to temporary brigadier on 30 March 1941, and commanded the 157th Infantry Brigade until late March 1942. He then became Director of Organization at the War Office before assuming command of the 155th Infantry Brigade in mid-February 1943. On 26 December 1943, promoted to temporary major general, he assumed command of the mountain warfare-trained 52nd (Lowland) Infantry Division from Major-General Neil Ritchie as its General Officer Commanding (GOC). He commanded the 52nd Division during the campaign in North-West Europe, from October 1944 until May 1945.
 Passage 3:Garcia Bacca studied under the Claretians and became a priest in 1925. He continued his formative studies at the University of Munich, University of Zurich and the University of Paris. Yet he quit the Church during the 1930s and began to study philosophy at the University of Barcelona. In 1936 he went into exile because of his criticism of Francisco Franco, traveling first to Ecuador, where he taught at the Central University of Ecuador (1939–42) where he became a close friend with the writer Alfredo Pareja Diezcanseco, then to México, where he taught at the UNAM (1942–46) and finally establishing in Venezuela in 1946 and becoming a Venezuelan citizen in 1952. He started teaching upon his arrival at the Central University of Venezuela in 1946 until his retirement in 1971. He won the National Prize for Literature in 1978 for his life's work.

Example Input: Question: Which of the two units held in reserve had more soldiers? Passage 1:As designed in 1931, the He 46 was a two-seat sesquiplane of mixed construction. The upper wing was swept back 10°. This is a common trick when a change in an aircraft's design moves the center of gravity to the rear; rather than moving the whole wing back to counter for the shift, it is easier to simply angle the wings back slightly, which requires very little change to the basic design, or even the overall structure of the wing. (The similarly angled wings on the Fairey Swordfish are due to just such a mid-program change to the weight distribution of the aircraft.) The tailplane was mounted high and braced by struts. The undercarriage was fixed, and the tail was fitted with a skid rather than a wheel. The He 46 prototype first flew in late 1931; its flight characteristics were good, but design improvements were incorporated. The small lower wing was removed, while the mainplane was increased in area by 22% and braced to the fuselage, transforming the He 46 into a parasol-wing monoplane. A more powerful engine was added to the second prototype, and a single 7.92 mm (.312 in) MG 15 machine gun for the rear seat was added to the third prototype.
 Passage 2:In planning for the actual attack, Manteuffel had divided his 5th Panzer Army into three corps composed of infantry, tanks, and supporting artillery. The main effort, or schwerpunkt, would consist of XLVII Panzer Corps and LVIII Panzer Corps advancing west across the River Our at Ouren from the south or left flank of the German army front. They would then occupy the transportation center of Bastogne, before crossing the Meuse River at Namur. The third group, LXVI Corps, would advance west on either side of the Schnee Eifel. This northernmost, or right wing, element would flank and begin an envelopment of the American forces occupying fortifications on the Schnee Eifel and then converge on the town of Winterspelt. From there, LXVI Corps would cross the Our river and occupy St. Vith on the first day of the attack. LXVI Corps was the weakest of the three corps, with no attached tank division or motor transport, but did include an attached assault gun battalion. The Panzer Lehr Division (Armor Demonstration Division) and the Führer Begleit Brigade (Führer Escort Brigade) were to be held in reserve, with the Führer Begleit only usable with Model's express permission. Manteuffel's preference for the "little slam", or limited solution, was reflected in the absence of planning beyond reaching the Meuse River.
 Passage 3:On 7 October 1593, the superintendent of the Venetian Republic founded a revolutionary new kind of settlement: Palmanova. The city’s founding date commemorated the victory of the Christian forces (supplied primarily by the Italian states and the Spanish kingdom) over the Ottoman Turks in the Battle of Lepanto in 1571, during the War of Cyprus. Also honored on 7 October was Saint Justina, chosen as the city's patron saint. Using all the latest military innovations of the 16th century, this small town was a fortress in the shape of a nine-pointed star, designed by Vincenzo Scamozzi. Between the points of the star, ramparts protruded so that the points could defend each other. A moat surrounded the town, and three large, guarded gates allowed entry. The construction of the first circle, with a total circumference of , took 30 years. Marcantonio Barbaro headed a group of Venetian noblemen in charge of building the town, Marcantonio Martinego was in charge of construction, and Giulio Savorgnan acted as an adviser. A second phase of construction took place between 1658 and 1690, and the outer line of fortifications was completed between 1806 and 1813 under the Napoleonic domination. The final fortress consists of: 9 ravelins, 9 bastions, 9 lunettes, and 18 cavaliers.

Example Input: Question: Between Young's 1969 album and his 1970 album, which sold more copies? Passage 1:He re-found his scoring form in the third tier scoring 16 times 1978–79 and seven times in 1979–80. He moved to Portsmouth in December 1980 and his six goals helped "Pompey" gain promotion to the Third Division. He scored 15 goals in 1980–81 but he failed to find the target in 1981–82 and left for Welsh side Wrexham. He scored just five goals in 1982–83 as the "Dragons" suffered relegation to the Fourth Division. Wrexham had a poor 1983–84 season as they finished in 20th position but Gregory scored a career best of 20 goals and helped Wrexham to win the Welsh Cup which at the time allowed entrance into European competitions. He played in both legs as Fourth Division Wrexham over came Portuguese club FC Porto but Italian side AS Roma proved too strong. He remained at Wrexham until the summer of 1986 and ended his career at with a season at his first club Peterborough United.
 Passage 2:Members of this band had already released an album in 1968 as The Rockets, and had appeared on record twice with Neil Young as Crazy Horse. The core trio from the Rockets, Danny Whitten, Billy Talbot, and Ralph Molina, provided instrumental backing for Young's 1969 album Everybody Knows This Is Nowhere, and performed on some songs from Young's 1970 album After the Gold Rush. Producer/keyboardist Jack Nitzsche, who had been a member of Phil Spector's Wrecking Crew and played on records by The Rolling Stones, had worked with Young on his debut album and on tracks for Buffalo Springfield. He was drafted into Crazy Horse to back up Young on their short tour in early 1970. During sessions for Gold Rush, they met teenage guitar prodigy Nils Lofgren, who joined the band in time for this album, picking up a contract with Reprise Records after the exposure garnered from their association with Young.
 Passage 3:Bundy was born in Malmö, Sweden, the son of Håkan Bundy and his wife Märta (née Thorell). When he was two-year-old Bundy suffered from polio - infantile paralysis. Then there was still no vaccine. He was lucky, a nerve in one calf was infected, while a two-year girl in his circle of friends, who also had the disease, died. He received a Candidate of Law degree from Lund University in 1946 and served at the Ministry for Foreign Affairs in 1948 and 1953. Bundy served in Prague in 1949, Paris in 1950, Canberra in 1957, Cairo in 1958 and Tehran in 1960. He was first secretary at the Foreign Ministry in 1960, director in 1963 and the acting chargé d'affaires in Nicosia in 1964. Bundy was commercial counsellor at the embassy in Washington, D.C. in 1965, deputy director at the Foreign Ministry in 1971 and embassy counsellor in Helsinki in 1972. He was ambassador in Kuwait City, Doha, Manama and Abu Dhabi from 1977 to 1980 and in Tehran from 1980 to 1985. Bundy served in the Foreign Ministry in Stockholm from 1985 to 1986.
