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.
One 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.

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

Now, solve this: Question: How many children does the artist have who Cantrell worked as a professional backing vocalist for in the late 1990s? Passage 1:In the years since September 11, 2001, Clinton has been subject to criticism that he failed to capture Osama bin Laden as President. In a September 24, 2006, interview with Fox News' Chris Wallace on Fox News Sunday, Clinton challenged his critics. According to Clinton, he faced criticism from various conservatives during his administration for being too obsessed with Bin Laden. Clinton also noted that his administration created the first comprehensive anti-terrorist operation, led by Richard Clarke—whom Clinton accuses the Bush Administration of demoting. Clinton also said he worked hard to try to kill Bin Laden. Former international negotiator and current businessman, financier and media commentator Mansoor Ijaz claimed that from 1996–1998, he had opened up unofficial negotiations with Sudan to lift terrorism sanctions from that country in exchange for intelligence information about the terrorist groups Islamic Jihad, Hezbollah and Hamas. He claimed that Sudan was also prepared to offer custody of terrorist mastermind Osama bin Laden, who had been living in the country and launching operations. According to Ijaz, neither Clinton nor National Security Advisor Sandy Berger responded to the situation. Bin Laden later left Sudan and established his operations in Afghanistan under the protection of the Taliban and, with his network, planned out terrorist attacks against American interests worldwide, including attacks on American embassies in Tunisia and Sudan as well as the bombing of USS Cole. The most infamous were the attacks of September 11, 2001 that occurred under Clinton's successor, George W. Bush nine months after Clinton left office. However, the 9/11 Commission Report later found no credible evidence to support the Sudan custody offer as the American Ambassador to the Sudan had no legal basis to ask for custody due to no indictment against Bin Laden:
 Passage 2:In the late-1990s, Cantrell established as a professional backing vocalist for artists such as Sean "Puffy" Combs. In 1999, she became member of the girl band 8th Avenue, a protegé of singer Teddy Riley. While the band recorded several songs and appeared on Blackstreet's 1999 album Finally, their material was left unused after Riley left Blackstreet to reform his previous group Guy and Blackstreet were subsequently dropped by Interscope Records, also leading to 8th Avenue's disbandment. Soon after, Cantrell was introduced by both a dancer friend and R&B singer Usher to Red Zone Entertainment head, music producer Tricky Stewart. Stewart originally wanted her to become a member of his girl group 321, but soon offered Cantrell to work with her as a solo artist following a fruitful recording session. Cantrell subsequently moved in with Stewart and his girlfriend in their Atlanta house, and was promptly placed with Arista Records head Antonio "L.A." Reid who offered the singer a contract with the company after hearing one song she wrote and sang in front of him and his staff. After a bidding war with several different labels, Reid's bid was the highest, prompting Cantrell to sign with them.
 Passage 3:MacDowall was appointed Lieutenant-Colonel of the 57th Regiment of Foot in 1791 and served in Flanders in 1793 and after serving as Commander-in-Chief in Ceylon from 1798 to 1804.

He was appointed Commander-in-Chief of the Madras Army in 1807. He was made Colonel of the 41st Regiment of Foot in 1808. Following a period of dispute with the civil government of Madras over his exclusion from its council, and the affair of the arrest of Quartermaster-General John Munro, he resigned his commission in January 1809 and took ship for England on the East Indiaman Lady Jane Dundas. The ship was lost with all hands near the Cape of Good Hope in March 1809.
