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: When was the Bureau of Scientific Relations disbanded? Passage 1:Rafael "Rafi" Eitan (; 23 November 1926 – 23 March 2019) was an Israeli politician and intelligence officer. He also led Gil and served as Minister of Senior Citizens. He was in charge of the Mossad operation that led to the arrest of Adolf Eichmann. He served as an advisor on terrorism to Prime Minister Menachem Begin, and in 1981 he was appointed to head the Bureau of Scientific Relations, then an intelligence entity on par with Mossad, Aman and Shabak. Eitan assumed responsibility for and resigned over the Jonathan Pollard affair, and the Bureau was disbanded. He was subject to an arrest warrant issued by the United States FBI. From 1985 until 1993, he was head of the government's Chemicals company, which was expanded under his leadership. After 1993, he became a businessman, noted for several large scale agricultural and construction ventures in Cuba. He was the chairman of the Vetek (Seniority) Association – the Senior Citizens Movement.
 Passage 2:In January 1996 former National Geographic photographer Charles O'Rear was on his way from his home in St. Helena, California, in the Napa Valley north of San Francisco, to visit his girlfriend, Daphne Irwin (whom he later married), in the city, as he did every Friday afternoon. He was working with Irwin on a book about the wine country. He was particularly alert for a photo opportunity that day, since a storm had just passed over and other recent winter rains had left the area especially green. Driving along the Sonoma Highway (California State Route 12 and 121) he saw the hill, free of the vineyards that normally covered the area; they had been pulled out a few years earlier following a phylloxera infestation. "There it was! My God, the grass is perfect! It's green! The sun is out; there's some clouds," he remembered thinking. He stopped somewhere near the Napa–Sonoma county line and pulled off the road to set his Mamiya RZ67 medium-format camera on a tripod, choosing Fujifilm's Velvia, a film often used among nature photographers and known to saturate some colors. O'Rear credits that combination of camera and film for the success of the image. "It made the difference and, I think, helped the 'Bliss' photograph stand out even more," he said. "I think that if I had shot it with 35 mm, it would not have nearly the same effect." While he was setting up his camera, he said it was possible that the clouds in the picture came in. "Everything was changing so quickly at that time." He took four shots and got back into his truck. According to O'Rear, the image was not digitally enhanced or manipulated in any way.
 Passage 3:In 1998, one week after winning E3 Harelbeke and the Brabantse Pijl in the same weekend, he won the Tour of Flanders, thereby equaling the race's record of three wins. One week later, Museeuw made a horrific fall in Paris–Roubaix on the Trouée d'Arenberg cobbled sector, leaving his kneeknap shattered. On top came a dangerous gangrene infection which nearly forced doctors to amputate his left leg. He fought back and resumed cycling after a long healing process, finishing third in the Tour of Flanders of 1999 and ninth in Paris–Roubaix, exactly one year after his horror crash. In 2000 he won Paris–Roubaix a second time after a 44 km solo. Upon crossing the finish line in victory, he lifted his left leg, pointing to his knee as a reminder of the injury that had almost ended his career two years before. Later that year, he was again injured in a motor cycle accident, causing a severe head trauma and several days in a coma. His dogged determination and powerful riding style won him legions of fans all over the world and made him all the more popular in his native Flanders.
