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 Input: Question: What age was the cartoonist and painter that White met in 2002? Passage 1:The Mets went on to sweep the Atlanta Braves in the 1969 National League Championship Series, but were heavy underdogs heading into the 1969 World Series against the Baltimore Orioles. Following a 4-1 loss in the series opener with Cy Young award winner Seaver on the mound, it seemed as if the Mets had little chance against the Orioles. However, the Mets bounced back, winning the next four games to capture their first world championship. Besides catching every inning in the post-season, Grote contributed offensively with a single in Game Two to keep a ninth inning rally alive and Al Weis followed with the game-winning hit. With Game Four tied, Grote doubled to start the tenth inning, then pinch runner Rod Gaspar scored the winning run when an errant throw hit J.C. Martin on the wrist. With Grote calling the pitches, the Mets pitching staff held the Orioles hitters to a .146 batting average during the series.
Passage 2:In 2002, White met the cartoonist and painter Gary Panter, better known as the designer of The Pee-wee Herman Show. They began collaborating on light shows, beginning the third incarnation of the Joshua Light Show, which continues to perform. Beginning with a series of performances at the Anthology Film Archives in 2004, the Joshua Light Show performs at festivals, museums and venues such as the Skirball Center, Abrons Art Center, the Museum of Contemporary Art Detroit, the Hayden Planetarium, the Barbican Centre, UC Davis, and the San Francisco Exploratorium. In 2007, the light show formed a relationship with composer and curator Nick Hallett. The Joshua Light Show has also been featured in museum exhibitions such as "Visual Music" at the Hirshhorn Museum in Washington DC and "The Summer of Love", originating at the Tate Liverpool, then travelling to Frankfurt, Vienna and the Whitney Museum in 2008. The Joshua Light Show's "Liquid Loops" was recently included in the exhibition "60-'69" at the Museum of Modern Art and was acquired by the museum for their permanent collection. In 2014 White collaborated with the artist Guy Richards Smit to create the video/installation/performance project "The Grossmalerman Show."
Passage 3:Born in Brescia, Italy, he began music lessons at the age of three, initially with the violin, but quickly switched to the piano. At eleven he entered the Milan Conservatory, graduating three years later at fourteen. In 1938, at the age of eighteen, he began his international career by entering the Ysaye International Festival in Brussels, Belgium, where he was placed seventh. A brief account of this competition, at which Emil Gilels took first prize and Moura Lympany second, is given by Arthur Rubinstein, who was one of the judges. According to Rubinstein, Benedetti Michelangeli gave "an unsatisfactory performance, but already showed his impeccable technique." A year later he earned first prize in the Geneva International Competition, where he was acclaimed as "a new Liszt" by pianist Alfred Cortot, a member of the judging panel, which was presided over by Ignacy Jan Paderewski.

Example Input: Question: Which of the two units held in reserve had more soldiers? Passage 1:As designed in 1931, the He 46 was a two-seat sesquiplane of mixed construction. The upper wing was swept back 10. This is a common trick when a change in an aircraft's design moves the center of gravity to the rear; rather than moving the whole wing back to counter for the shift, it is easier to simply angle the wings back slightly, which requires very little change to the basic design, or even the overall structure of the wing. (The similarly angled wings on the Fairey Swordfish are due to just such a mid-program change to the weight distribution of the aircraft.) The tailplane was mounted high and braced by struts. The undercarriage was fixed, and the tail was fitted with a skid rather than a wheel. The He 46 prototype first flew in late 1931; its flight characteristics were good, but design improvements were incorporated. The small lower wing was removed, while the mainplane was increased in area by 22% and braced to the fuselage, transforming the He 46 into a parasol-wing monoplane. A more powerful engine was added to the second prototype, and a single 7.92mm (.312in) MG 15 machine gun for the rear seat was added to the third prototype.
Passage 2:In planning for the actual attack, Manteuffel had divided his 5th Panzer Army into three corps composed of infantry, tanks, and supporting artillery. The main effort, or schwerpunkt, would consist of XLVII Panzer Corps and LVIII Panzer Corps advancing west across the River Our at Ouren from the south or left flank of the German army front. They would then occupy the transportation center of Bastogne, before crossing the Meuse River at Namur. The third group, LXVI Corps, would advance west on either side of the Schnee Eifel. This northernmost, or right wing, element would flank and begin an envelopment of the American forces occupying fortifications on the Schnee Eifel and then converge on the town of Winterspelt. From there, LXVI Corps would cross the Our river and occupy St. Vith on the first day of the attack. LXVI Corps was the weakest of the three corps, with no attached tank division or motor transport, but did include an attached assault gun battalion. The Panzer Lehr Division (Armor Demonstration Division) and the Fuhrer Begleit Brigade (Fuhrer Escort Brigade) were to be held in reserve, with the Fuhrer Begleit only usable with Model's express permission. Manteuffel's preference for the "little slam", or limited solution, was reflected in the absence of planning beyond reaching the Meuse River.
Passage 3:On 7 October 1593, the superintendent of the Venetian Republic founded a revolutionary new kind of settlement: Palmanova. The city's founding date commemorated the victory of the Christian forces (supplied primarily by the Italian states and the Spanish kingdom) over the Ottoman Turks in the Battle of Lepanto in 1571, during the War of Cyprus. Also honored on 7 October was Saint Justina, chosen as the city's patron saint. Using all the latest military innovations of the 16th century, this small town was a fortress in the shape of a nine-pointed star, designed by Vincenzo Scamozzi. Between the points of the star, ramparts protruded so that the points could defend each other. A moat surrounded the town, and three large, guarded gates allowed entry. The construction of the first circle, with a total circumference of , took 30 years. Marcantonio Barbaro headed a group of Venetian noblemen in charge of building the town, Marcantonio Martinego was in charge of construction, and Giulio Savorgnan acted as an adviser. A second phase of construction took place between 1658 and 1690, and the outer line of fortifications was completed between 1806 and 1813 under the Napoleonic domination. The final fortress consists of: 9 ravelins, 9 bastions, 9 lunettes, and 18 cavaliers.

Example Input: Question: How long had Hafez al-Assad been the President of Syria for by the year he sent troops into Lebanon to fight PLO forces? Passage 1:PA 741 begins at an intersection with PA 722 in the borough of East Petersburg in Lancaster County, heading to the south on two-lane undivided Lemon Street, which is unsigned and locally maintained. The road passes homes prior to crossing into East Hempfield Township, where it becomes Rohrerstown Road and continues through industrial parks. PA 741 gains a center left-turn lane and becomes signed at the Commercial Avenue intersection. The route continues to an interchange with PA 283, at which point it becomes state-maintained. The road crosses the Little Conestoga Creek into Manheim Township after PA 283. The route becomes two lanes again and turns east prior to turning southwest and crossing the Little Conestoga Creek back into East Hempfield Township. At this point, PA 741 becomes McGovernville Road and comes to a bridge over Norfolk Southern's Lititz Secondary and Amtrak's Keystone Corridor. The road passes a mix of homes and woods as it comes to the Harrisburg Pike intersection, where it makes a turn to the south onto Rohrerstown Road, a three lane road with a center left-turn lane. PA 741 passes homes to the west and a branch of Lancaster General Hospital to the east prior to coming to the US 30 interchange. In the area of the interchange, PA 741 is briefly a divided highway. Following US 30, the route becomes a two-lane undivided road and passes residences prior to crossing Norfolk Southern's Columbia Secondary and entering the residential and commercial community of Rohrerstown. Here, PA 741 crosses PA 23. After leaving Rohrerstown, the road passes a mix of farms and businesses prior to an intersection with PA 462.
Passage 2:Blignaut went to the State School in his birthplace Paarl, where he subsequently attended the Gymnasium (Grammar School). After his exams Blignaut went to Cape Town, where he joined the colonial administration. In 1861 he passed the examination for the State Service Certificate of the Cape Colony and in 1862 he moved to the Orange Free State. Here he was appointed to the position of clerk to the Landdrost and Justice of the Peace of Philippolis (17 September 1862). At the time, civil, judicial, and military administration were still very much in the same hand. In view of Basotho threats, President Brand ordered the reorganisation of the Orange Free State defence, and the formulation of clear regulations for the different Volunteer Corps, which were administered by the Landdrosts' offices. For Philippolis Blignaut and J.G. Fraser attended the conference.
Passage 3:According to historians William Cleveland and Martin Bunton, Beirut became an international banking center because of its "laissez-faire economic system". Business owners from Cairo, Damascus, and Baghdad moved to Beirut for economic opportunities. Despite Lebanon's cultural liberalism and economic prosperity, sectarian tensions remained as citizens identified themselves through their sects. With Muslims calling for greater representation and with Cold War tensions, Lebanese leadership had to decide whether to ally with the West or with Egypt, Syria and its Arab history. Christians wanted to continue alliances with the West but Muslims were drawn to Nasser's pan-Arabism. Multiple factors including sectarian tensions and Palestinian refugee settlement in southern Lebanon contributed to the beginnings of the Lebanese Civil War. In 1976, Syrian President Hafez al-Assad sent troops into Lebanon to fight PLO forces on behalf of Christian militias. This led to escalated fighting until a cease-fire agreement later that year that allowed for the stationing of Syrian troops within Lebanon. The Syrian presence in Lebanon quickly changed sides; soon after they entered Lebanon they had flip-flopped and began to fight the Christian nationalists in Lebanon they allegedly entered the country to protect. The Kateab Party and the Lebanese Forces under Bachir Gemayel strongly resisted the Syrians in Lebanon. Following the Israeli invasion into Lebanon in 1982, new Lebanese President Amine Gemayel sought the support of Syrian troops to stabilize the region. Syria fought Israeli troops after the latter's invasion of Lebanon.
