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 was the price of the land that the United States bought from France in 1803? Passage 1:Originally the property of the Toronto Maple Leafs, the young goalie played seven games for the Leafs in the 1960–61 season. Picked up by the Montreal Canadiens in the inter-league draft the following season, Maniago underwent a lengthy apprenticeship in the minor leagues, spending the better part of five years on the farm. The high point of his years with Montreal was a 14-game stint in relief of the ailing Jacques Plante during the 1963 season. He had a sparkling season for the Minneapolis Bruins of the Central Hockey League in 1965, winning the league's most valuable player award, after which he was dealt to the New York Rangers. Maniago competed against Ed Giacomin and Don Simmons for the starting goal position in 1966, playing 28 games for the last place team. On March 12, 1966, in Chicago, Maniago allowed the Chicago Black Hawks' star left winger Bobby Hull's 51st goal of the season, the first time in league history that any player had scored more than 50 goals in one year. After the game, Maniago insisted that Chicago's crafty forward Eric Nesterenko had interfered with him during the play: "Nesterenko lifted the blade of my stick, and the puck went under it." Giacomin firmly won the job the next season as the much-improved Rangers made the playoffs, and Maniago played in just six games as his backup.

 Passage 3:Although born a native of Powhatan County, Virginia, William Ashley had already moved to Ste. Genevieve, in what was then a part of the Louisiana Territory, when it was purchased by the United States from France in 1803. On a portion of this land, later known as Missouri, Ashley made his home for most of his adult life. Ashley moved to St. Louis, around 1808, and became a Brigadier General in the Missouri Militia, during the War of 1812. Before the war, he did some real estate speculation and earned a small fortune manufacturing gunpowder from a lode of saltpeter mined in a cave, near the headwaters of the Current River in Missouri. When Missouri was admitted to the Union, William Henry Ashley was elected its first Lieutenant Governor, serving, from 1820–1824, under Governor Alexander McNair. Ashley ran for governor of Missouri, in the August 1824 election, but was defeated.
