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: What country is the Bristol Channel located in? Passage 1:Taft Broadcasting would be reorganized as Great American Broadcasting in 1987. However, the company would declare bankruptcy in 1993, and was reorganized as Citicasters, Inc. (their sister AM station would be sold to another locally-based company, Jacor). In 1996, Citicasters itself merged with Jacor; as part of the merger, WKRQ was sold to Boston-based American Radio Systems (ARS) on March 7, 1997 (this separated WKRQ from their long-time TV sister station). However, in September 1997, Infinity Broadcasting (which was renamed CBS Radio in December 2005) would acquire ARS as part of a group deal; the merger was completed the following June. CBS owned WKRQ until November 2006, when it was sold to Entercom. Entercom, in turn, announced in January 2007 that it would be swapping its entire Cincinnati cluster, including WKRQ, to Bonneville International together with three radio stations in Seattle, Washington, for all three of Bonneville's FM radio stations in San Francisco, California, and $1 million cash. In May 2007, the station launched an online stream from its website at www.wkrq.com. Also that month, Bonneville officially took over the operations of Entercom's former Cincinnati radio cluster through a local marketing agreement. Entercom officially closed on its acquisition of the stations on November 30. The sale of the Cincinnati cluster to Bonneville was conditionally approved in November 2007, with the remainder of the deal finally approved in March 2008. The official transfer of the Cincinnati stations to Bonneville took place on March 14.
 Passage 2:Thomson, a wing half, started his career with Thornton Rangers in his native Fife, before moving to Dundee, where he played for four years. In 1929 he moved to Everton. His Everton career had an inauspicious start, with the club suffering relegation in his first season. The following season, he gained a Second Division winners medal as Everton made an immediate return to the top flight, and then added a First Division medal in 1932 as Everton became champions. Later that year he made his international debut, representing Scotland in a 5–2 home international defeat against Wales, though this was to be his only international appearance. He played in the 1933 FA Cup Final, helping Everton to a 3–0 win against Manchester City. Later in his time at Everton first team appearances became more uncommon for Thomson as he was displaced from the team by Joe Mercer. Thomson retired from playing in 1938, having made 299 appearances for Everton, in which he scored five goals.
 Passage 3:Because of the natural layout of the harbour, Ilfracombe became a significant safe port (registered port of refuge) on the Bristol Channel. It also had trade routes between Kinsale and Tenby, which made the port stronger. In 1208 it was listed as having provided King John with ships and men to invade Ireland; in 1247 it supplied a ship to the fleet that was sent to conquer the Western Isles of Scotland; 6 ships, with 79 men were sent to support the siege of Calais. Ilfracombe was the last disembarkation point for two large forces sent to subdue the Irish. The building which sits on Lantern Hill by the harbour, known as St Nicholas's Chapel (built 1361) is reputed to be the oldest working lighthouse in the UK; a light/beacon has been there for over 650 years. The town was also home to the Bowen family. James Bowen was master of HMS Queen Charlotte, the flagship of Richard, Earl Howe at the 1794 "Glorious First of June" battle. James Bowen was commissioned by Howe for his leadership in the battle, he rose through the levels - commander of the Argot, the Dreadnought, and in Georgian England titled "defender of Madeira", led the fleet which rescued the British army at Corunna in the Peninsula war, and retired as a Rear Admiral, Commissioner of the Royal Navy. Captain Richard Bowen (1761–1797) James Bowen's younger brother, a British naval commander on the ship HMS Terpsichore, served under Lord Nelson, and was killed at the battle of Santa Cruz de Tenerife. John Bowen (1780–1827), son of James Bowen, a naval officer and colonial administrator founded the first settlement of Tasmania at Risdon Cove in 1803 - the settlement which later became known as Hobart. Lieutenant A E Down, was initially posted to Ilfracombe to lead a protection ship for the customs and excise, he married a local girl, rose through the levels to retire as vice Admiral, his son joined the navy aged 14 (his first navy kit is on display at National Maritime Museum Greenwich). In 1802 James Meek married Down's daughter and settled in the town, James Meek was appointed the Comptroller of Victuals to the Royal Navy in 1832, he was knighted, and died in Ilfracombe 1852.
