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: Does South Australia have a lot of wetlands? Passage 1:Following Operation Barbarossa, the German invasion of the Soviet Union in June 1941, and the entry of the United States into World War II in December 1941, the Soviet Union became a less attractive patron for Sheng than the Kuomintang. By 1943 Sheng Shicai switched his allegiance to the Kuomintang after major Soviet defeats at the hands of the Germans in World War II, all Soviet Red Army military forces and technicians residing in the province were expelled, and the Republic of China National Revolutionary Army units and soldiers belonging to Ma Bufang moved into Xinjiang to take control of the province. Ma Bufang helped the Kuomintang build roads linking Qinghai and Xinjiang, which helped both of them bring Xinjiang under their influence. At August 1942 Sheng met Dekanozov, former Soviet ambassador to Nazi Germany and Vice Commissar of the Ministry of Foreign Affairs of the USSR, in Ürümqi and demanded that the Soviet Union withdraw all military forces and political officers from Xinjiang in three months and remove all Soviet equipment from the territory of Soviet Concessions, including closing the Soviet oil fields in Tushangze (Jungaria) and the Soviet Aircraft Manufacturing Plant in Ürümqi. On 29 August 1942, the day after Dekanozov left Ürümqi, Sheng met Madame Chiang Kai-shek, wife of the Chinese Generalissimo, who flew to Ürümqi with a letter from Chiang Kai-shek promising his forgiveness to Sheng for all of his previous deals. Sheng was appointed the head of the Kuomintang branch in Xinjiang in 1943 and allowed Kuomintang cadres into the province. To forge his ties with Kuomintang, on 17 September 1942 Sheng arrested a number of Chinese communists sent to Xinjiang by the Central Committee of the Communist Party of China in 1938 and executed them in 1943. Among the executed was Mao Zemin, brother of Mao Zedong. In the summer of 1944, following the German defeat on the Eastern Front, Sheng attempted to reassert control over Xinjiang and turned to the Soviet Union for support again. He arrested a number of Kuomintang cadres in Ürümqi and sent a letter to Stalin offering to "incorporate Xinjiang into USSR as its 18th Soviet Socialistic Republic." Sheng Shicai asked Stalin for the post of ruler of the new Soviet Republic. Stalin refused to deal with Sheng and forwarded the confidential letter to Chiang Kai-shek. As a result, the Kuomintang removed him from the province in August 1944 and appointed him to a low-level post in the Ministry of Forestry in Chongqing.
 Passage 2:The Coongie Lakes is a freshwater wetland system located in the Far North region of South Australia. The lakes system is located approximately north of the Adelaide city centre. The wetlands includes lakes, channels, billabongs, shallow floodplains, deltas, and interdune swamps. It lies on the floodplain of Cooper Creek, an ephemeral river flowing through a desert landscape in the Lake Eyre Basin which rarely, after occasional large floods, empties into Lake Eyre. The wetland system has been recognised both as being of international importance by designation under the Ramsar Convention with a listing on 15 June 1987 and being nationally important within Australia with a listing in A Directory of Important Wetlands in Australia (DIWA). Its extent includes the regional town of Innamincka, the Malkumba-Coongie Lakes National Park, the Innamincka Regional Reserve, the Strzelecki Regional Reserve and the Coongie Lakes Important Bird Area.
 Passage 3:The oldest true fossils of baleen are only 15 million years old because baleen rarely fossilizes, and scientists believe it originated considerably earlier than that. This is indicated by baleen-related skull modifications being found in fossils from considerably earlier, including a buttress of bone in the upper jaw beneath the eyes, and loose lower jaw bones at the chin. Baleen is believed to have evolved around 30 million years ago, possibly from a hard, gummy upper jaw, like the one a Dall's porpoise has; it closely resembles baleen at the microscopic level. The initial evolution and radiation of baleen plates is believed to have occurred during Early Oligocene when Antarctica broke off from Gondwana and the Antarctic Circumpolar Current was formed, increasing productivity of ocean environments. This occurred because the current kept warm ocean waters away from the area that is now Antarctica, producing steep gradients in temperature, salinity, light, and nutrients, where the warm water meets the cold.
