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.

Let me give you an 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.

Question: How many Star Trek films had been created by the time United States v. Ancheta got underway? Passage 1:During the 1780s and 1790s, German-speaking Lutherans began to move west from the original 13 states on the Atlantic coast into the portion of the old Northwest Territory formed 1787, that is now the future state of Ohio (and included territories north of the Ohio River, future states of Indiana, Illinois, Michigan, Wisconsin, and eastern Minnesota), with the numbers increasing after Ohio gained statehood in 1803. The Pennsylvania Ministerium sent two itinerant Lutheran pastors, Wilhelm Georg Forster and Johannes Stauch, to minister to the immigrants. By 1818 the Ministerim has sent another ten pastors, including Paul Henkel and John Michael Steck. These pastors began meeting together as the Ohio Conference of the Pennsylvania Ministerium, with the first convention on October 17–19, 1812, in Washington County, Pennsylvania. and the last on September 20–24, 1817, in New Philadelphia, Ohio. However, the Ohio Conference was not an independent synod, and so any candidates for the pastoral office were required to go to Pennsylvania for ordination. Most candidates found it difficult to make that trip across the Appalachian Mountains, so instead the Ohio Conference merely licensed them to preach. In order to remedy this, the conference asked for and received permission from the Pennsylvania Ministerium to form a new synod, and on September 14, 1818, in Somerset, Ohio, the General Council of the Evangelical Lutheran Preachers in Ohio and the Adjacent States () was organized.
 Passage 2:In 2006, Klausner presided over United States v. Ancheta, the federal prosecution of Jeanson James Ancheta of Downey, California, the first botnet-related prosecution in U.S history. Following Ancheta's guilty plea, Klausner sentenced Ancheta to 57 months in prison for various botnet-related crimes. In 2016, Klausner presided over a copyright case filed by the estate of Spirit guitarist Randy Wolfe against Led Zeppelin founders Robert Plant and Jimmy Page. The estate of Wolfe alleged that Wolfe was entitled to a writing credit for the song "Stairway to Heaven"; Klausner ruled in April 2016 that a jury could find "substantial similarity" between the elements of the two songs. In another copyright case arising from the Star Trek fan film Prelude to Axanar, Klausner rejected various motions by both parties in January 2017, setting the stage for a civil trial on the matter to go forward. The parties settled the suit. In August 2017, Klausner dismissed a class-action lawsuit filed by boxing fans who contended that the 2015 Floyd Mayweather Jr. vs. Manny Pacquiao boxing match was deceptively marketed because Pacquiao failed to disclose a shoulder injury that affected his performance. Klausner ruled that fans of sporting events have no right to have the event meet their expectations for excitement. In October 2017, Klausner ruled in favor of the plaintiff Coachella Music Festival in a lawsuit against the fledgling "Filmchella" film festival, finding that the names were likely to cause consumer confusion.
 Passage 3:Shreveport was once a major player in United States oil business, and at one time could boast Standard Oil of Louisiana as a locally based company. The Louisiana branch was later absorbed by Standard Oil of New Jersey. Beginning in 1930, United Gas Corporation, the nation's busiest pipeline operator and massive integrated oil company, was headquartered in Shreveport. Pennzoil performed a hostile takeover in 1968, and forced a merger. In the 1980s, the oil and gas industry suffered a large economic downturn. This affected all of the regional economy, and many companies cut back jobs or went out of business, including a large retail shopping mall, South Park Mall, which closed in the late 1990s. Its major facilities were adapted for use by Summer Grove Baptist Church. Shreveport suffered severely from this recession, and many residents left the area. Since that time, Shreveport has largely transitioned to a service economy. In particular, there has been rapid growth in the gaming industry. The city hosts various riverboat gambling casinos, and, before Hurricane Katrina in 2005, was second only to New Orleans in Louisiana tourism. Nearby Bossier City is home to one of the three horse racetracks in the state, Harrah's Louisiana Downs. Casinos in Shreveport-Bossier include Sam's Town Casino, Eldorado Casino, Horseshoe Casino, Boomtown Casino, Diamond Jacks Casino (formerly Isle of Capri), and Margaritaville Resort Casino. The Shreveport-Bossier Convention and Tourist Bureau is the official tourism information agency for the region. The bureau maintains a comprehensive database of restaurants, accommodations, attractions, and events.
