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 river that bounded the “Gericht auf der Höhe” was the longest? Passage 1:Lea Hall is a former country house standing to the northwest of the village of Wimboldsley, Cheshire, England. It dates from the early part of the 18th century, and was built for the Lowndes family. During the 19th century the house was owned by Joseph Verdin. Additions, including dormer windows, were made in the 19th century. During the 20th century the house was divided into three flats. The house is constructed in red brick with ashlar dressings and a tiled roof. It is in two storeys, with an attic and a basement. The roof is large and hipped, with a viewing platform. The entrance front is symmetrical, in five bays, the central bay protruding slightly forward. This bay contains a doorway with a swan's nest pediment decorated with scrolls, and containing a crest with the initials J V (for Joseph Verdin). The authors of the Buildings of England series describe the house as a "perfect brick box, delightful if just a little funny to look at". It is recorded in the National Heritage List for England as a designated Grade II* listed building.
 Passage 2:Following its involvement in The Troop, FujiFilm commissioned Glory Film Co. to make a series of films to demonstrate its new motion picture filmstocks. For these projects Glory employed leading cinematographers: Oscar-winners Jack Cardiff OBE, BSC, ASC, (The African Queen) and Ronnie Taylor BSC (Gandhi) together with Phedon Papamichael ASC (Walk the Line), John de Borman BSC (The Full Monty), Sue Gibson BSC (Spooks), Thierry Arbogast AFC (The Fifth Element), Ron Stanett CSC (Evel Knievel) and Tony Pierce-Roberts BSC (A Room With a View). The films were shot at Pinewood (LightsII) and Shepperton studios (Lights II, Return of The Shadow), with locations including Hastings in East Sussex (The Glow). 'Lights II' (2005) featured the last cinema performance of John Mills (at age 96). He played a tramp and was photographed by cinematographer Jack Cardiff, himself 90 years old.
 Passage 3:The mediaeval historical development that Homberg experienced closely matches that experienced by neighbouring villages such as Kirrweiler, Deimberg, Buborn, Langweiler and Hausweiler. Like these places, Homberg belonged until 1140 to the Nahegau, and then thereafter until 1263 to the Waldgraviate, which itself had arisen from the Nahegau. As far as is now known, Homberg had its first documentary mention in 1319. In the document in question, an arbitrator confirmed that Waldgrave Friedrich of Kyrburg had to forgo all his claims to rights to Hoenberg and a series of other places in the “Gericht auf der Höhe” (“Court on the Heights”). The Gericht auf der Höhe was said to be a constituent district of the “Hochgericht auf der Heide” (“High Court on the Heath”), which comprised, roughly, lands in a triangle bounded by the Nahe, the Glan and the Steinalp (another river). The 1319 document dealt with a dispute between the two Waldgravial sidelines of Kyrburg and Dhaun-Grumbach. About 1344, in his own documents, the name “Friedrich von Hoenberg” appeared. He was obviously a nobleman who came from Homberg, but nothing else about him has come to light. The villages under the Gericht auf der Höhe, among which was Homberg, were pledged first, in 1363, by Johann von Dhaun to Sponheim-Starkenburg and then in 1443 by Waldgrave and Rhinegrave Friedrich to the last of the Counts of Veldenz, namely Friedrich III, whose daughter Anna married King Ruprecht's son Count Palatine Stephan. The document whereby this arrangement was laid out referred to the village's inhabitants as the “poor people of Grumbach”. By uniting his own Palatine holdings with the now otherwise heirless County of Veldenz – his wife had inherited the county upon her father Friedrich III's death in 1444, but not his comital title – and by redeeming the hitherto pledged County of Zweibrücken, Stephan founded a new County Palatine, as whose comital residence he chose the town of Zweibrücken: the County Palatine – later Duchy – of Palatinate-Zweibrücken. Thus, Homberg, and the other villages, too, lay within this duchy, but they were all returned to the Waldgraviate in 1477 when the pledge was redeemed.
