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: Where does the route end that 104 intersects with in Stamford? Passage 1:Irene was daughter of despotēs Theodore Komnenos Doukas, ruler of Epirus, and Maria Petraliphaina (sister of the sebastokratōr John Petraliphas). In 1230 Irene and her family were captured by the troops of tsar Ivan Asen II of Bulgaria in the battle of Klokotnitsa and they were taken in Tarnovo, where Irene grew up in the Palace. Irene became known for her beauty and the widowed tsar fell in love with her. They married in 1237. According to a Byzantine author, Ivan Asen II loved Irene "no less than Antony loved Cleopatra", and she may have been his mistress for some years before their marriage in 1237. By marrying Irene, Ivan Asen II would have broken church canons, as his daughter, Maria Asanina Komnena, from his marriage to Anna (Anisia) was married to Irene's uncle, Manuel of Thessalonica. There is some evidence that the Bulgarian church opposed the marriage and that a patriarch (called either Spiridon or Vissarion) was deposed or executed by the irate tsar.
 Passage 2:Dido Elizabeth Belle was born into slavery in 1761 in the British West Indies to an enslaved African woman known as Maria Belle. (Her name was spelled as Maria Bell in her daughter's baptism record.) Her father was 24-year-old Sir John Lindsay, a member of the Lindsay family of Evelix branch of the Clan Lindsay and a descendant of the Clan Murray, who was a career naval officer and then captain of the British warship HMS Trent, based in the West Indies. He was the son of Sir Alexander Lindsay, 3rd Baronet and his wife Amelia, daughter of David Murray, 5th Viscount Stormont. Lindsay is thought to have found Maria Belle held as a slave on a Spanish ship which his forces captured in the Caribbean; he appears to have taken her as his concubine (see plaçage). Lindsay returned to London after the war in 1765 with his young daughter, Dido Belle. When they arrived in England he took her to Kenwood House just outside the city, the home of his uncle, William Murray, 1st Earl of Mansfield, and his wife Elizabeth Murray, Countess of Mansfield. Belle was baptised as Dido Elizabeth Belle in 1766 at St. George's, Bloomsbury. The Murray family raised Belle as an educated woman along with their niece and Dido's cousin, Lady Elizabeth Murray, whose mother had died. However, Belle remained a slave until Mansfield finally granted her freedom from slavery in his will in 1793.
 Passage 3:Route 104 begins at an intersection with Route 137 in the Bulls Head section of Stamford and heads north, passing by GE Capital, then crossing the Rippowam River, up through North Stamford and onto New York state line. About north of the river, Route 104 crosses under the Merritt Parkway (Route 15) at Exit 34 into the North Stamford section of the city. After another , Route 104 crosses over the Mianus River, through the Long Ridge section of the city, as it heads towards the New York state line. The road ends in the town of Pound Ridge, New York and continues as Westchester County Road 3. Route 104 is known as Long Ridge Road throughout its length and is classified as a principal arterial road, carrying traffic volumes of as much as 30,000 vehicles per day, particularly near the Merritt Parkway interchange. Route 104 is four lanes wide from Route 137 to Route 15, and two lanes wide north of Route 15.
