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 input: 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.

Q: Question: On what date did Recitation win its maiden race at Newbury Racecourse? Passage 1:After finishing third over five furlongs on his racecourse debut, Recitation won a maiden race over the same distance at Newbury Racecourse, beating I'll See You by half a length. The colt was then moved up sharply in class for the Group Three Coventry Stakes over six furlongs at Royal Ascot in June in which he was ridden by Greville Starkey and started at odds of 11/1. In a performance which Timeform described as "a revelation", Recitation took the lead a quarter mile from the finish and drew clear of the field to win easily by five lengths from Motavato, Bel Bolide and Another Realm. The form of the race was subsequently boosted when the third and fourth placed horses won the Gimcrack Stakes and the Richmond Stakes respectively. In the July Stakes at Newmarket Racecourse Recitation started 2/5 favourite against two opponents, but was beaten two and a half lengths by Age Quod Agis.
Passage 2:WEA was at first reluctant to issue it as a single, and even Howard initially had a few doubts about whether commercial radio was ready for such a weighty political subject; however, Howard insisted on its release to make a statement on the British invasion of Australia. "Solid Rock" peaked at No.#2 on the Australian Kent Music Report Singles Chart, remaining in the Top50 for 26 weeks. It also reached No.#31 on the US Billboard Mainstream Rock Chart and appeared on the Billboard Hot 100. In November 2013, "Solid Rock" was voted No. 20 in the 3MMM/Herald-Sun Australian Top-40 chart of the last 40 years. Goanna released their debut album, Spirit of Place, in December. It was produced by Trevor Lucas, a member of UK folk rock group Fairport Convention, who had returned to Australia in 1979. Spirit of Place reached No.2 on the Kent Music Report Albums Chart, within two weeks of its release and remained there for 10 weeks, alternating with Midnight Oil's 10, 9, 8, 7, 6, 5, 4, 3, 2, 1 for the No. 1 & No. 2 spot. It also reached No.179 on the US Billboard 200. For the album, Goanna were Rose Bygrave on keyboards, Peter Coughlan on bass guitar, Graham Davidge (ex-Little River Band) on guitar, Warrick Harwood, Shane Howard, his sister Marcia Howard on backing vocals, Mick "The Reverend" O'Connor on keyboards and Robbie Ross on drums. An ever-changing line-up saw Harwood reluctantly leave the band. The follow-up single "Razors Edge" released in March 1983 reached No. 36 on the national charts.
Passage 3:Born into a noble Polish family in South-eastern Poland, she was the daughter of Wadysaw Skarzynski and his wife, Dorota Goebiowska. Teresa was educated at an elite Catholic boarding school for girls, run by the Sisters of the Immaculate Conception, in Jazowiec in the Podole region. In 1902 she married Count Edward ubienski (18711919), a member of a once powerful clan and went to live on the family estate in aszow. They had a son, Stanisaw, born in 1906 followed by a daughter, Izabela, born in 1910. There, Teresa became an active member of the Polish Red Cross and continued supporting the 14th Regiment of Jazlowiec Uhlans, an association dating from her school days. She was widowed in 1919. Her son attended a military academy and passed out as a cavalry officer, later killed in the September campaign of 1939. Early during the German occupation of Poland in World War II Teresa moved to Warsaw and lived at no. 6 Sierpnia Street. During the occupation, she organised assistance for the civilian population of the capital. Her flat was also the venue of clandestine meetings of the Polish resistance cells. In 1942, she was betrayed to the Nazi authorities, arrested and taken to the Pawiak prison for interrogation. From there, she was sent to Auschwitz concentration camp and later moved to Ravensbruck concentration camp where her death sentence was commuted owing to the timely intervention of the Swedish Red Cross.
