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: 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: How many days after he broke his leg did Port Vale defeat the Bristol Rovers? Passage 1:In 1897, a European exhibitor first screened a selection of silent short films at the Victoria Public Hall in Madras. The films all featured non-fictional subjects; they were mostly photographed records of day-to-day events. In Madras (present-day Chennai), the Electric Theatre was established for the screening of silent films. It was a favourite haunt of the British community in Madras. The theatre was shut down after a few years. This building is now part of a post office complex on Anna Salai (Mount Road). The Lyric Theatre was also built in the Mount Road area. This venue boasted a variety of events, including plays in English, Western classical music concerts, and ballroom dances. Silent films were also screened as an additional attraction. Swamikannu Vincent, an employee of the South Indian Railways in Coimbatore, purchased a film projector and silent films from the Frenchman Du Pont and set up a business as film exhibitor. He erected tents for screening films. His tent cinema became popular and he travelled all over the state with his mobile unit. In later years, he produced talkies and also built a cinema in Coimbatore.
 Passage 2:He joined Third Division club Port Vale in October 1987, manager John Rudge splashing out £20,000. Scoring on his debut at Vale Park in a 2–1 win over Bristol Rovers on 19 October, he was soon a big hit, becoming the club's joint-top scorer in the 1987–88 season with 10 goals (along with Darren Beckford). He played 48 league and cup games in 1988–89 but broke his leg in a 1–1 draw at Bolton Wanderers on 25 April 1989, and so missed out on the play-off final victory over Bristol Rovers. He managed to recover, but did not re-capture his first team position and in March 1990 was loaned back to Peterborough United, who were then under Mark Lawrenson's stewardship; Peterborough paid £40,000 for his services on a permanent basis the next month.
 Passage 3:The 2005–06 NBA season would be the first and only NBA season for the 28-year-old 7 ft 0 in center to play in the National Basketball Association (NBA) with the Los Angeles Clippers. During this season, N'Dong barely played any notable parts with the team, appearing in 23 games with a 7-minute per game average, starting only once for them. However, the Clippers would ultimately have a surprising season under their belt in his sole season there, making it to the Western Conference semifinals for the first time in franchise history, barely upsetting the Phoenix Suns in the process. In December 2006, he signed with the Russian club Spartak St. Petersburg. N'Dong moved to the Spanish ACB league later that season and signed with Unicaja Málaga for the 2006–07 ACB League Play-Offs to replace the injured Daniel Santiago. On July 14, 2007, he re-signed with Malaga on a one-season contract. He has also played with the Cleveland Cavaliers NBA Summer League squad in 2007.

Example Input: Question: Where is the headquarters of the publishing house which published The Divine located? Passage 1:Mauro González moved out to Temperley on 13 July, while Lucas Wilchez did the opposite on 16 July. Almagro held three friendlies on 16 July, two versus Colegiales and one against the Argentina U23s; they'd draw one and lose two. Maximiliano García agreed to go to Comunicaciones on 18 July. New player Facundo Suárez netted a goal in each game as Almagro drew and then beat Ferro Carril Oeste on 20 July. Gustavo Turraca returned to Primera B Nacional on loan on 23 July, having been relegated from it with Los Andes in 2018–19. On 24 July, Agustín Coscia was loaned from Rosario Central. A friendly with Quilmes was postponed on 26 July, in order to preserve the Estadio Centenario Ciudad de Quilmes pitch following heavy rain; rescheduling was confirmed.
 Passage 2:Charles Bertram was born in London in 1723. He was the son of an English silk dyer who was usually accounted to have emigrated to Copenhagen, Denmark, among the retinue of Princess Louisa, a daughter of George II, upon her marriage to Crown Prince Frederick of Denmark in 1743. (The prince became King Frederick V three years later.) Other sources suggest the father immigrated earlier, in 1738. The father established himself as a hosier in 1744, and Charles seems to have benefited from the warm reception that Louisa and her retinue received from the Danes. On 5 July 1747, Charles petitioned the University of Copenhagen's Consortium for admission to study history, antiquities, philosophy, and mathematics. This seems to have been granted, although students were generally required to adhere to the Danish Church and Bertram remained Anglican. He became a friend and protégé of Hans Gram, the royal librarian and a member of the privy council. On 23 March 1748, Bertram petitioned the king to be permitted to give public lectures on the English language and became a teacher of English in the Royal Marine Academy in Copenhagen. (Some accounts name him as a professor, rather than a tutor; if so, that status would have been granted some years later, as he was a new undergraduate in 1747.) His 1749 chrestomathy An Essay on the Excellency and Style of the English Tongue has been called the initiation of English-language printing in Denmark. A brother apparently died at sea in 1752, and at some point he married Cathrine Marie Gold.
 Passage 3:The Divine was published in the U.S. by First Second Books, featuring a blurb by author Yann Martel, best known for the international bestseller Life of Pi. It was released in July 2015 and has hit the New York Times Best Sellers list. It has since received highly positive reviews. Publishers Weekly had chosen The Divine for "top ten graphic novel for spring 2015", describing it later on as: "Heady, hellacious, and phantasmagoric". Jesse Karp on his Booklist review wrote: "Stunning artwork and creeping dread weave together in this satisfying and moving page-turner". Douglas Wolk from The New York Times described it as "a too rare example of artists getting top billing", referring to the artwork by Asaf and Tomer Hanuka. Joshua Rivera from GQ wrote: "The Divine's story is unflinching and raw, and its art is quite possibly the most beautiful of any comic this year". Michael Mechanic from Mother Jones called it "beautifully rendered", while io9 defined it as "Your next comics obsession". Rich Barrett from Mental Floss chose it for "The most interesting comics of the week" and praised it for being "stunning, cohesive combination [of elements]". Terry Hong, from The Smithsonian Asian Pacific American Center blog, wrote: "can’t-turn-away riveting [...] Unrelenting and uninterruptible", and the Eisner nominated comics blog Comics & Cola dubbed it "superb" and chose it for its pick of the month.
