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.
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-Lo 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 (18941973) 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.

Problem: Question: In what country are the Caha Mountains? Passage 1:Starting at Glengarriff, the Beara Way enters the Glengarriff Woods Nature Reserve and then climbs into the Caha Mountains to an altitude of as it traverses the pass north of Sugarloaf mountain before descending to reach the village of Adrigole. From Adrigole, the trail follows the southern flanks of Hungry Hill and the Slieve Mish Mountains to reach Castletownbere. A spur route makes a circuit of Bere Island, which is connected to Castletownbere by a ferry service. The route from Castletownbere to Allihies is via an old cattle droving path. Copper mining was the main activity in Ahillies for many years and the remains of abandoned mine working dot the landscape. Another circular spur route starts from Allihies and brings the trail to the very tip of the Beara Peninsula where a cable car connects the trail with Dursey Island. From Ahillies, the trail follows a miners' track and climbs the copper-rich crags above the village, crossing a mountain pass to reach Eyeries. A ridge along the coast connects Eyeries with Ardgroom. The trail then crosses into County Kerry to reach Tuosist, via Lauragh. From Tuosist, the Way crosses the northern slopes of Knockagarrane and then passes between Clonee Lough and Lough Inchiquin before crossing a mountain pass. The route diverges here, continuing north to Kenmare or south to Bonane. The final stage returns to Glengarriff via Bonane Heritage Park and Esk mountain. A spur route connects Glengarriff with Kealkill, Gougane Barra and Ballingeary.
Passage 2:The medicinal use of wine was frequently studied by the Greeks, including Hippocrates, who did extensive research on the topic. He used wine as a cure for fevers, to ease convalescence and as an antiseptic. He also studied the effect of wine on his patients' stool. Various types of wine were prescribed by Greek doctors for use as an analgesic, diuretic, tonic and digestive aid. The Greeks were also aware of some negative health effects, especially those arising from the consumption of wine beyond moderation. Athenaeus made frequent mention of wine's ability to induce hangover and suggested various remedies for it. The poet Eubulus noted that three bowls (kylikes) were the ideal amount of wine to consume. The quantity of three bowls to represent moderation is a recurring theme throughout Greek writing (today, the standard 750 ml bottle contains roughly three to six glasses of wine, depending on serving size). In his c. 375 BC play Semele or Dionysus, Eubulus has Dionysus say:
Passage 3:At the time, the Thirty Years' War was raging across Europe. Gabriel Bethlen, prince of Transylvania saw an opportunity to unite the two Hungarian principalities, Transylvania and Royal Hungary, and sacked Vienna in November 1619. He also asked Sultan Osman II for aid, but this was unsuccessful. The Commonwealth was relatively uninvolved in this war but the Polish king, Zygmunt III Waza, sent an elite and ruthless mercenary unit, the Lisowczycy, to aid his Habsburg allies. They defeated the Hungarian lord George Rakoczi at the Battle of Humenne in 1619, and thus, cut the supply lines of Transylvanian forces. Then Gaspar Graziani, ruler of Moldavia, switched sides and joined Poland.
