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.

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 7.92 mm (.312 in) 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 Führer Begleit Brigade (Führer Escort Brigade) were to be held in reserve, with the Führer 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.

Question: Who was the oldest among those players who tied for second highest scorer in FIFA World Cup qualifying? Passage 1:McDowell appeared as Dr. Samuel Loomis in Rob Zombie's remakes of Halloween and Halloween II (in 2007 and 2009, respectively). Although the films were not well received critically, they performed better at the box office and McDowell was widely praised for his performances and for being perfectly cast. He also played Desmond LaRochette in Robert Whitlow's The List (2007), and Irish patriarch Enda Doyle in Red Roses and Petrol (2003). His next film is the Canadian vampire comedy rock and roll film Suck (2009) with actor/director Rob Stefaniuk and the upcoming Alex Wright film Two Wolves. In December 2009, he made an appearance in the music video "Snuff" by the heavy metal band Slipknot. He appears, uncredited, as the curator Lombardi, in the film The Book of Eli (2010). McDowell portrayed Satan in the Christian comedy thriller film Suing the Devil (2011).
 Passage 2:When Jaya Prada was a teenager, she performed a dance at her school's annual function. A film director in the audience offered her a three-minute dance number in the Telugu film Bhoomi Kosam. She was hesitant, but her family encouraged her to accept it. She was paid only 10 rupees for her work in the film, but the rushes of those three minutes of film were shown to the major figures of the Telugu film industry. Major filmmakers offered her starring roles in quality films, and she accepted them. She became a huge star in 1976 with major hit films. Director K. Balachander's black-and-white film Anthuleni Katha (1976) showcased her dramatic skills; K. Viswanath's color film Siri Siri Muvva (1976) showed her playing a mute girl with excellent dancing skills; and her title role as Sita in the big-budget mythological film Seetha Kalyanam confirmed her versatility. In 1977, she starred in Adavi Ramudu, which broke box office records and which permanently cemented her star status. The song "Aaresukoboyi Paresukunnanu" performed by Prada and co-star N.T. Rama Rao became a mass hit. Important filmmakers were casting her and repeating her in their films. Filmmaker Vijay introduced her to Kannada cinema in his 1977 super-hit movie Sanadi Appanna alongside Kannada matinee idol Raj Kumar. The movie is also known to be the only movie to feature shehnai rendition by Ustad Bismillah Khan. Jaya Prada repeated her successful pairing with Rajkumar in films such as Huliya Halina Mevu (1979), Kaviratna Kalidasa (1983) and Shabdavedhi (2000). In 1979, K. Balachander repeated her in the Tamil film Ninaithale Inikkum opposite Kamal Haasan and Rajinikanth in which she played a terminally-ill patient. She continued to act in more films in Telugu opposite actors such NTR, ANR, Krishna, Krishnam Raju and Sobhan Babu throughout the 70s and 80s. K. Viswanath remade Siri Siri Muvva (1976) in Hindi as Sargam, introducing Jayaprada to Bollywood in 1979. The film was successful and she became a star there as well. She earned her first Filmfare nomination as Best Actress but couldn't capitalize on her success since she couldn't speak Hindi.
 Passage 3:Alexis Sánchez is a Chilean professional footballer who represents the Chile national football team as a striker. Nicknamed El Niño Maravilla ("The Boy Wonder"), he made his debut for his country in a 1–0 victory over New Zealand in April 2006. His first international goal came on his eighth appearance for Chile when he scored Chile's only goal in a 2–1 defeat to Switzerland in a friendly tournament in Vienna. , Sánchez is his country's top scorer and has the most caps, with 43 goals in 132 appearances. He passed the previous record of 37, held by Marcelo Salas, when he scored the opening goal against Germany in the group stage of the 2017 FIFA Confederations Cup in June 2017. He scored most recently against Ecuador in a 2–1 win during the 2019 Copa América. Despite Sánchez scoring seven goals, making him second-equal top scorer in 2018 FIFA World Cup qualifying (along with Lionel Messi, Gabriel Jesus and Felipe Caicedo), Chile failed to qualify for the finals. Sánchez made his most recent and 132nd appearance for Chile in a 0–0 draw against Colombia in October 2019.
