Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage 1: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lô during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,
. Passage 2: John Ford (1894–1973) was an American film director whose career spanned from 1913 to 1971. During this time he directed more than 140 films. Born in Maine, Ford entered the filmmaking industry shortly after graduating from high school with the help of his older brother, Francis Ford, who had established himself as a leading man and director for Universal Studios. After working as an actor, assistant director, stuntman, and prop man – often for his brother – Universal gave Ford the opportunity to direct in 1917. Initially working in short films, he quickly moved into features, largely with Harry Carey as his star. In 1920 Ford left Universal and began working for the Fox Film Corporation. During the next ten years he directed more than 30 films, including the westerns The Iron Horse (1924) and 3 Bad Men (1926), both starring George O'Brien, the war drama Four Sons and the Irish romantic drama Hangman's House (both 1928 and both starring Victor McLaglen). In the same year of these last two films, Ford directed his first all-talking film, the short Napoleon's Barber. The following year he directed his first all-talking feature, The Black Watch.
. Passage 3: Since the late 1970s, the central part of NYU is its Washington Square campus in the heart of Greenwich Village. Despite being public property, and expanding the Fifth Avenue axis into Washington Square Park, the Washington Square Arch is the unofficial symbol of NYU. Until 2008, NYU's commencement ceremony was held in Washington Square Park. However, due to space constraints, ceremonies are now held at the Yankee Stadium. Important facilities at Washington Square are the Elmer Holmes Bobst Library, designed by Philip Johnson and Richard Foster, who also designed several other structures, such as Tisch Hall, Meyer Hall, and the Hagop Kevorkian Center. When designing these buildings Johnson and Foster also set up a master plan for a complete redesign of the NYU Washington Square campus. However, it was never implemented. Other historic buildings include the Silver Center (formerly known as "Main building"); the Brown Building of Science; Judson Hall, which houses the King Juan Carlos I of Spain Center; Vanderbilt Hall, the historic townhouse row on Washington Square North; The Grey Art Gallery at 100 Washington Square East, housing the New York University art collection and featuring museum quality exhibitions; the Kaufman Management Center; and the Torch Club – the NYU dining and club facility for alumni, faculty, and administrators. Just a block south of Washington Square is NYU's Washington Square Village, housing graduate students and junior and senior faculty residences in the Silver Towers, designed by I. M. Pei, where an enlargement of Picasso's sculpture Bust of Sylvette (1934) is displayed.

Solution: 1
Reason: The question refers to the 704th unit and task about war which is decribed by Passage 1.

Now, solve this instance: Question: What is the population of the town where Gawler established his own firm? Passage 1:Maryanoff has been active in the fields of medicinal chemistry and organic chemistry. He is an inventor of topiramate, a unique sugar sulfamate drug, which has been marketed worldwide for the treatment of epilepsy and migraine, attaining annual sales of more than $2 billion. Topiramate is also a principal component of the antiobesity drug Qsymia. Maryanoff is an internationally renowned expert in drug design and drug discovery, especially in the application of protein structure-based drug design. He made seminal contributions to understanding the stereochemistry and mechanism of the Wittig reaction; adapted the cobalt-catalyzed alkyne trimerization to the synthesis of macrocycles; and devised novel peptides that undergo self-assembly to mimic native collagen structurally and functionally. Maryanoff is an author on 280 scientific publications, including several books (editor), book chapters, and review articles. He is an inventor on 100 issued U.S. patents, has presented over 185 invited lectures worldwide, and mentored 11 postdoctoral associates. Maryanoff organized and edited a special memorial issue of the Journal of Medicinal Chemistry to honor the memory of Dr. Paul Janssen (2005) and has served on numerous editorial advisory boards for scientific journals and research grant review committees.
 Passage 2:Gawler was born in Adelaide, South Australia, to Caroline (née Philpot) and Henry Gawler. His grandfather, George Gawler, was the second Governor of South Australia. Gawler attended St Peter's College, Adelaide, and then studied law at the University of Adelaide. Gawler was called to the bar in South Australia in 1886, and left for Western Australia later that year, establishing his own firm in Perth. At one time, he was in partnership with Robert Bruce Burnside, a future Supreme Court justice. Having previously served on the Peppermint Grove Road Board for a period, Gawler was elected to parliament at a 1910 Legislative Council by-election, which had been caused by the resignation of Walter Kingsmill. He died in office in May 1915 (aged 54), of typhoid fever. He had married Eva Mary Waldeck in 1893, with whom he had four children.
 Passage 3:Benfica's first competitive game was an away Primeira Liga opener against Rio Ave. Sánchez Flores did not have Reyes, and Jonathan Urretaviscaya started instead. At the Estádio dos Arcos, the home team scored first with a 55th-minute goal from José Semedo. A minute later Benfica evened the score, with Urreta assisting Nuno Gomes for the 1–1 final result. It was the fourth consecutive time that Benfica failed to win their league start. Sánchez Flores said that Rio Ave created unexpected problems: "It was not a easy game. We had a quality opponent, who left us trailing when we were not expecting it." During the last week of August Benfica brought in Honduran striker David Suazo on loan, sold right-back Nélson Marcos to Betis and was paired with Italian side Napoli in the UEFA Cup first-round draw on 29 August. A day later, Benfica hosted Porto for the first Clássico of the season. The visitors started better, converting a 10th-minute penalty kick for a Kostas Katsouranis foul against Lucho González. In the 56th minute, Cardozo exploited a mistake by Helton to head in the equaliser. Three minutes later Katsouranis was sent off, but Benfica held the tie until the final whistle. Quique Flores said, "It was a good game. In normal conditions we would have done better, but circumstances made it a little harder."
