You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

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.

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

New input: Question: Is the show that "Hurricane!" is part of still airing today? Passage 1:William Briwere was granted the lordship of the Manor of Bridgwater by John of England in 1201, and founded Bridgwater Friary. Through Briwere's influence, King John granted three charters in 1200; for the construction of Bridgwater Castle, for the creation of a borough, and for a market. Bridgwater Castle was a substantial structure built in Old Red Sandstone, covering a site of 8 or 9 acres (32,000 to 36,000 m²). A tidal moat, up to wide in places, flowed about along the line of the modern thoroughfares of Fore Street and Castle Moat, and between Northgate and Chandos Street. The main entrance opposite the Cornhill was built with a pair of adjacent gates and drawbridges. In addition to a keep, located at the south-east corner of what is now King Square, documents show that the complex included a dungeon, chapel, stables and a bell tower. Built on the only raised ground in the town, the castle controlled the crossing of the town bridge. A thick portion of the castle wall and water gate can still be seen on West Quay, and the remains of a wall of a building that was probably built within the castle can be viewed in Queen Street. The foundations of the tower forming the north-east corner of the castle are buried beneath Homecastle House. William Briwere also founded St John's hospital which, by the time of the Dissolution of the Monasteries under Henry VIII, was worth the substantial sum of almost 121 pounds, as well as starting the construction of the town's first stone bridge. William Briwere also went on to found the Franciscan Bridgwater Friary in the town.

Meteorologists Hugh Willoughby, Bob Sheets (then director of the National Hurricane Center) and Jeff Masters were shown in the episode. The episode was released on VHS home video under the same episode title and distributed by WGBH Boston video. In 2004, the Nova episode was released on DVD and featured a different cover picture and title style. In 1997, UAV Corp. also distributed the Nova episode under the title "Deadly Hurricanes" which contains additional footage of Hurricane Andrew and Hurricane Iniki of 1992.
