Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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.

Solution: 1
Reason: The question refers to the 704th unit and task about war which is decribed by Passage 1.

Now, solve this instance: Question: Which of the operas that Vogl played at the Met had the longest run? Passage 1:He played the role of Loge in Richard Wagner's Das Rheingold at Munich Court Opera on September 22, 1869, with his wife, Therese Vogl, playing the role of Wellgunde. He also played the role of Siegmund in Wagner's Die Walküre, also at Munich, on June 26, 1870. Therese Vogl played the role of Siegmund's sister and lover Sieglinde in the same performance. His Munich debut was as Max in Weber's Der Freischütz. He sang at Bayreuth, Berlin, London and the Metropolitan Opera in New York City. At Bayreuth, he played the role of Loge in the first complete Ring cycle on August 13, 1876. His performance in the role caused fellow singer Lilli Lehmann to comment that he was born for the part and that his Loge had never been equalled. His debut at the Metropolitan Opera was in the title role of Lohengrin on January 1, 1890, and he also sang Loge, Siegmund, the title role of Tannhäuser, Tristan in Tristan und Isolde, and Siegfried in both Siegfried and Götterdämmerung at the Met. Heinrich Vogl was also the first performer to play the roles of Loge and Siegfried in London, which he did in the first Ring cycle in London at Her Majesty's Theatre, with Anton Seidl conducting and his wife playing the role of Brünnhilde.
 Passage 2:A well-known fictional mongoose is Rikki-Tikki-Tavi, who appears in a short story of the same title in The Jungle Book (1894) by Rudyard Kipling. In this tale set in India, the young mongoose saves his family from a krait and from Nag and Nagaina, two cobras. The story was later made into several films and a song by Donovan, among other references. A mongoose is also featured in Bram Stoker's novel The Lair of the White Worm. The main character, Adam Salton, purchases one to independently hunt snakes. Another mongoose features in the denouement of the Sherlock Holmes story "The Adventure of the Crooked Man", by Sir Arthur Conan Doyle. The Indian Tamil devotional film Padai Veetu Amman shows Tamil actor Vinu Chakravarthy changing himself into a mongoose by using his evil tantric mantra, to fight with goddess Amman. However, the mongoose finally dies in the hands of the goddess.
 Passage 3:Dani Sordo, who targeted himself for a podium finish, led nine-time world champion Sébastien Loeb by 7.2 seconds after two days. Both drivers benefited from low start positions in the sweltering mountain speed tests above León. Ott Tänak, 11 seconds off the pace in third, drove around overheating problems in his Toyota Yaris, ahead of last year winner Kris Meeke. Defending world champion Sébastien Ogier limited his losses from second in the start order in fifth place, despite a spin. Norwegian Andreas Mikkelsen was sixth, only 1.5 seconds behind the Frenchman. It was a nightmare catastrophe for championship leader Thierry Neuville. The road opener fared worst in the conditions and lost more than 20 seconds due to a fuel pressure problem and a power steering issue in his i20. He placed seventh overall when Jari-Matti Latvala retired with alternator problems before SS9. Elfyn Evans retired from the rally because of rolling out though he managed to reach the finish line, while teammate Teemu Suninen and Esapekka Lappi retired from the day due to hitting a barrier and crashing respectively. WRC 2 leader Pontus Tidemand, Gus Greensmith and Pedro Heller completed the top ten.
