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: Where is the Tiyas Military Airbase? Passage 1:A Military Shield detachment was present at the Palmyra frontline in December 2016, when ISIL launched a large-scale offensive in the area. This unit was later accused by the Tiger Forces to have fled in disarray after the first serious Islamist attacks, leaving Palmyra and Tadmor's remaining pro-government defenders to their fate. Soon after, Palmyra fell to ISIL, and the Military Security Shield Forces were among the pro-government units that sent reinforcements to help defend the nearby Tiyas Military Airbase from the next Islamist attack. The unit was also involved in the following government counter-offensive in the area. On 23 February 2017, al-Masdar News reported that over 900 Syrian Marines had joined the Military Security Shield Forces in order to avoid being drafted into the regular army. In June 2017, the Military Shield Forces took part in an anti-ISIL offensive in eastern Hama. Later that year, the militia took part in the battle to retake all of Deir ez-Zor city from ISIL. Afterwards, Military Shield militiamen began to garrison towns in eastern Syria which had been retaken from ISIL, such as Mayadin. The pro-opposition Syrian Observatory for Human Rights accused the militia of requisitioning food from local civilians during this time.
 Passage 2:Haggard was the son of John Haggard, a lawyer, and his wife Caroline Hodgson. His father was Chancellor of Lincoln, Winchester and Manchester. Haggard was educated at Christ Church, Oxford where he rowed for his college and university. In 1845 he was a member of the Oxford crew in the Boat Race. In 1846 at Henley, Haggard partnered William Milman to win Silver Wherries, beating Thomas Howard Fellows and his brother. He was also a member of the Oxford coxed four which won the Stewards' Challenge Cup. In 1847 he was a member of the Oxford eight which won the Grand Challenge Cup at Henley, beating Cambridge in a year when there was no Boat Race at Putney. He was also in the Christ Church four which won the Stewards' Challenge Cup in a row-over. In 1848 at Henley Haggard repeated the Grand Challenge Cup and Stewards' Challenge Cup wins, and also won the Silver Wherries with Milman again, when LD Bruce and S Wallace, their opponents in the final were disqualified.
 Passage 3:The first recorded sentence in the Polish language reads: "Day ut ia pobrusa, a ti poziwai" ("Let me grind, and you take a rest") — a paraphrase of the Latin "Sine, ut ego etiam molam." The work, in which this phrase appeared, reflects the culture of early Poland. The sentence was written within the Latin language chronicle Liber fundationis from between 1269 and 1273, a history of the Cistercian monastery in Henryków, Silesia. It was recorded by an abbot known simply as Piotr (Peter), referring to an event almost a hundred years earlier. The sentence was supposedly uttered by a Bohemian settler, Bogwal ("Bogwalus Boemus"), a subject of Bolesław the Tall, expressing compassion for his own wife who "very often stood grinding by the quern-stone." Most notable early medieval Polish works in Latin and the Old Polish language include the oldest extant manuscript of fine prose in the Polish language entitled the Holy Cross Sermons, as well as the earliest Polish-language Bible of Queen Zofia and the Chronicle of Janko of Czarnków from the 14th century, not to mention the Puławy Psalter.
