Part 1. Definition
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.
Part 2. 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.

Part 3. Exercise
Question: In what Georgia counties is the Chattahoochee-Oconee National Forest located? Passage 1:San Severo lies on the Daunia, and various Neolithic settlements have been detected. In the early Middle Ages, the area was not inhabited or defined. Between the Lombards and the Byzantine ages, the Benedictine monastery at Cassino was established, and with it, the cult of the apostle of Saint Severinus of Noricum. San Severo was founded in the 11th century around a small church built by the Benedictine monks from Montecassino. It rapidly developed as a trade town. In 1053, it was the scene of the historical victory of Robert Guiscard over the papal troops under Pope Leo IX (see Battle of Civitate). In the eleventh century, San Severo was the route of the Via Sacra Langobardorum and a primitive church arose dedicated to Saint Severino, from which continued an influx of pilgrims to Monte Sant'Angelo and movement of people and goods. The town was therefore called Castellum Sancti Severini ("Fortified Town of San Severo").
 Passage 2:The movement of Protestant Reformation, led by Martin Luther in the Holy Roman Empire and John Calvin in France, had an important impact on music in Paris. Under Calvin's direction, between 1545 and 1550 books of psalms were translated from Latin into French, turned into songs, and sung at reformed services in Paris. The Catholic establishment reacted fiercely to the new movement; the songs were condemned by the College of Sorbonne, the fortress of orthodoxy, and in 1549 one Protestant tailor in Paris, Jacques Duval, was burned at the stake, along with his song book. When the campaign against the new songs proved ineffective, the Catholic Church, at the Council of Trent (1545-1563) which launched the Counter-Reformation, also launched a musical counter-reformation. It was calling for an end to complex but unintelligible chants, simpler melodies, and more serious and elevated lyrics.
 Passage 3:SR 255 begins at an intersection with SR 115 (Clarkesville Highway) east of Cleveland, in White County. The route heads northeast, and crosses over Blue Creek and travels through Batesville. Farther to the east, it passes New Blue Creek Cemetery and intersects SR 384 (Duncan Bridge Road). It then crosses over Brasstown Creek shortly before it crosses over Chattahoochee River and enters Habersham County. Just after the county line, SR 255 crosses over Amys Creek and meets SR 17 (Unicoi Turnpike). The two highways share a concurrency, heading in a northwestern direction. During the concurrency, SR 17/SR 255 intersect SR 255 Alt. (Ben T. Huiet Highway) and cross Maudlin Mill, Car, and Chickamauga Creeks before they reach Sautee Nacoochee. At Maudlin Mill Creek, they cross back into White County. There, SR 255 splits to the north. Just prior to curving to the northeast, the route crosses over Ben Creek, and just after that curve, it crosses over Bean Creek and enters Chattahoochee-Oconee National Forest. Northeast of Bean Creek, SR 255 intersects Sky Lake Road, which leads to Sky Lake. Just after Sky Lake Road, the highway has a second crossing over Chickamauga Creek. It heads to the east, and re-enters Habersham County, at the same time exiting the Chattahoochee-Oconee National Forest. A short while afterward, SR 255 has a second intersection with SR 255 Alt. Just northeast of that intersection, the route re-enters the Chattahoochee–Oconee National Forest. The highway heads north-northeast to meet its northern terminus, an intersection with SR 197 in Batesville. SR 255 travels through the historic Sautee Valley Historic District.
