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 city had a greater population when the "pod" system was enacted; Tucson, Arizona or Charlotte, North Carolina? Passage 1:West Suffield Mountain, like much of the Metacomet Ridge, is composed of basalt, also called traprock, a volcanic rock. The mountain formed near the end of the Triassic Period with the rifting apart of the North American continent from Africa and Eurasia. Lava welled up from the rift and solidified into sheets of strata hundreds of feet thick. Subsequent faulting and earthquake activity tilted the strata, creating the cliffs and ridgeline of West Suffield Mountain. Hot, dry upper slopes, cool, moist ravines, and mineral-rich ledges of basalt talus produce a combination of microclimate ecosystems on the mountain that support plant and animal species uncommon in greater Connecticut. West Suffield Mountain is also an important raptor migration path. (See Metacomet Ridge for more information on the geology and ecosystem of West Suffield Mountain).
 Passage 2:Mandal was selected in Nepal Under-19s fourteen man squad in the 2008 Under-19 World Cup, making six Youth One Day International appearances in the tournament. In 2010, Mandal was selected in Nepal's fourteen man squad for the 2010 World Cricket League Division Five in February 2010, making his senior debut in the tournament in a controversial match against the United States. Both teams would progress to the final of the tournament, where Mandal made his second appearance of the tournament. In April of that year, he played for Nepal in the 2010 ACC Trophy Elite, making six appearances. Having gained promotion in the World Cricket League by winning Division Five earlier in 2010, Nepal played in the Division Four in August of that year, with Mandal selected as part of Nepal's fourteen man squad for the tournament, where he made seven appearances. In November 2010, he played for Nepal in the 2010 Asian Games, making three appearances against Hong Kong, the Maldives and Sri Lanka, though Nepal didn't progress far enough in the tournament for Mandal to become a medalist.
 Passage 3:Once the S-curve is established, the committee must place the teams throughout the four regions. They were originally referred to as East, Mideast, Midwest, and West. In 1985, the Mideast designation became the Southeast, and later the South Regional in 1998. The women's tournament continued to use the Mideast terminology through 2004. In 2004, the NCAA started to identify the men's regions only by the city in which the regional semifinals and finals were played, with the same change being made for the women's tournament in 2005. The NCAA reverted to the East/South/Midwest/West designations for the men's tournament starting in 2007, but continues to designate women's regionals by their cities. Typically the cities selected will be spread throughout the country and conform roughly to the old geographic distinctions. While the regions are named for certain cities, the first and second round games are played in different cities which need not be anywhere near the regional finals. In 2005 the Austin, Texas men's regional was fed by games in Indianapolis, Indiana; Tucson, Arizona; Charlotte, North Carolina; and Worcester, Massachusetts. This is due to the "pod" system enacted before the 2002 tournament to minimize travel for as many teams as possible, especially in the early rounds. Any team may be sent to any region and any pod, although the tournament does try to keep teams, especially the top-seeded teams, closer to home. However, in 2004, Pittsburgh played its first two tournament games in Milwaukee and not in Buffalo or Columbus, cities to which it was closer. This was done to keep a lower-seeded team, the Wisconsin Badgers, close to its campus. Similarly, two east-coast teams, Maryland and Syracuse, traveled to Denver, where their opening round opponents were BYU and UTEP, both of which were geographically closer to Denver. In addition, in 2009, Kansas and West Virginia, the two higher seeds, traveled to Minneapolis to play their opponents North Dakota State and Dayton, although Dayton and North Dakota State are geographically closer to Minneapolis than Kansas and West Virginia. To make matters worse for both latter teams, Kansas City (Kansas) and Greensboro NC (West Virginia) were both 1st-2nd round sites that year.
