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: What were the combined ages of Abu al-Dahab and Ismail Bey the year that they were dispatched by Ali Bey? Passage 1:John Michael Drew (17 October 1865 – 17 July 1947) was an Australian politician who served as a member of the Western Australian Legislative Council for 41 years in two separate terms between 1900 and his death in 1947. Born at Wanerenooka, Northampton, Western Australia, Drew established and edited several newspapers circulating in the Geraldton region before entering politics. A strong opponent of federation, he was elected to the Legislative Council in 1900. Nominally independent, Drew aligned himself with the Labor Party, and served in several Labor ministries during the early 1900s, in positions such as Minister for Agriculture, Minister for Lands, and Colonial Secretary. He officially joined the party in 1911, having been admitted to caucus sittings the previous year. During World War I, Drew supported conscription, but this issue, coupled with the ineffectual Scaddan Ministry, led to him losing his seat at the 1918 election. He regained his seat at the 1924 election, and subsequently served as chief secretary of the party, as well as Minister for Education, Health, and the North-West. Drew died of cancer in 1947, and was buried at Karrakatta Cemetery.
 Passage 2:Also in 1764, while Uthman was leading the annual Hajj pilgrimage, he had a violent confrontation with Ali Bey al-Kabir, an influential mamluk from Egypt. When Ali Bey was exiled by the governor of Egypt to Gaza (part of Damascus Eyalet) in 1766, Uthman attempted to drive him out. Uthman managed to have his son, Darwish Pasha, appointed as the governor of Sidon in November 1770 and sometime prior to that, had his other son, Muhammad Pasha, appointed as governor of Tripoli. In 1771, Ali Bey, by now the rebellious governor of Egypt, had dispatched an army under commanders Abu al-Dahab and Ismail Bey to subdue Damascus. Together with Zahir, the combined armies of Egypt and Palestine defeated Uthman's army outside of Damascus and Uthman fled north to the city of Homs. The city fell shortly thereafter, although they did not capture the Citadel of Damascus, which was subsequently besieged. However, Abu al-Dahab suddenly withdrew from the area, citing his fears of violating Islamic principles since seizing an Ottoman province was in effect a direct challenge to the authority of the Ottoman sultan, who held the highest religious honor as the caliph of Islam.
 Passage 3:In June 1974, Guilfoyle was appointed to Billy Snedden's shadow ministry as the Coalition's spokesperson for the media. She supported Malcolm Fraser in the March 1975 leadership spill, and when he was successful she was moved to the higher-profile education portfolio. Following the dismissal of the Whitlam Government in November 1975, Guilfoyle was appointed Minister for Education in Fraser's caretaker ministry. This made her the first woman to hold a cabinet-level ministerial portfolio; is the first woman to be appointed to a Cabinet portfolio following her appointment as Minister for Education in the first Fraser government in 1975 she was the second woman appointed to cabinet, after Enid Lyons, and the second to be given a ministerial portfolio, after Annabelle Rankin. In December 1975, following the Coalition's victory at the 1975 election, Guilfoyle was appointed Minister for Social Security in the second Fraser Ministry. Her new portfolio was initially placed outside of cabinet, but she was reinstated in July 1976 after Ivor Greenwood's retirement. According to Fraser, she "contributed significantly to cabinet debates ... she could be totally relied on and she could think for herself – she wasn't a captive to the bureaucracy".
