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.
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-Lo 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 (18941973) 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.

Problem: Question: What was the rope made from that the use of running rigging has evolved from? Passage 1:Running rigging is the cordage used to control the shape and position of the sails. Materials have evolved from the use of Manilla rope to synthetic fibers, which include dacron, nylon and kevlar. Running rigging varies between fore-and-aft rigged vessels and square-rigged vessels. They have common functions between them for supporting, shaping and orienting sails, which employ different mechanisms. For supporting sails, halyards (sometimes haulyards), are used to raise sails and control luff tension. On gaff-rigged vessels, topping lifts hold the yards across the top of the sail aloft. Sail shape is usually controlled by lines that pull at the corners of the sail, including the outhaul at the clew and the downhaul at the tack on fore-and-aft rigs. The orientation of sails to the wind is controlled primarily by sheets, but also by braces, which position the yard arms with respect to the wind on square-rigged vessels.
Passage 2:During the first week of September 1861, all pretense of neutrality in Kentucky ended when Maj. Gen. Leonidas Polk ordered Brig. Gen. Gideon Pillow advance Confederate troops up to Hickman, Kentucky. On September 18, Kentucky legislature approved the introduction of Federal troops from outside the state, the pro-Confederate legislators staying away. The next day, Simon Bolivar Buckner, former commander of the Kentucky State Guard, established a Confederate headquarters at Bowling Green, Kentucky, while troops under Felix K. Zollicoffer seized Barbourville. Shortly afterwards, Zollicoffer arrived at Cumberland Ford with approximately 3,200 men, consisting of four infantry regiments, a field battery of six guns, and four cavalry companies. This posed an imminent threat to Union control of central Kentucky, at a time when increasing numbers of Confederates in the Big Sandy Valley of eastern Kentucky appeared about to enter the Bluegrass region through McCormack's Gap (Frenchburg). In response, Brig. Gen. George H. Thomas ordered troops from Camp Dick Robinson to southeast Kentucky to halt any movement toward Big Hill, Richmond and Lexington. Former Vice President of the United States John C. Breckinridge and his ally, Col. Humphrey Marshall, added to Thomas's concerns with a call for "Peace Men" and "States' Rights Men" to assemble in Lexington for drill. However, both Breckinridge and Marshall instead rode to Mt. Sterling to join the Confederate forces in western Virginia, where Marshall took command of the Army of Eastern Kentucky posted at Piketon (Pikeville).
Passage 3:He adopted "Danish" as his Takhallus (pen-name). Bachay, Titli, Phool, his first collection of poems, was published in 1997. He quickly garnered recognition for the anger he expressed through his works, in which he often made reference to his experiences as a member of the African diaspora; his work attracted the attention of leading Urdu critic Shamsur Rahman Farooqi, who had them published in Indian literary journal Shabkhoon. In 2000, he emigrated to the United States; he had remarked to a friend that he would prefer to be "a third class citizen of a first class country than a first class citizen of a third class country," but put off going through the procedures for almost two years due to his ambivalence about leaving his home. He first took up residence in the Kew Gardens neighborhood of Queens, New York City; he chose it because of its diversity, which helped him to feel less of a stranger as well as affording him the opportunity to study others' cultures. At first, he could only find job as a security guard, but he eventually joined the faculty of New York University; he later moved to the University of Maryland as a language consultant.
