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.
One 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.

Explanation: The question refers to the 704th unit and task about war which is decribed by Passage 1.

Now, solve this: Question: What type of car did Wilson Fittipadli use at the Belgium race? Passage 1:RAF Mildenhall opened on 16 October 1934. King George V reviewed 350 aircraft there in 1935 on the occasion of his Silver Jubilee. This historical event is commemorated by a memorial tablet located in front of the Building 562, the current 100 ARW headquarters. During World War II, Mildenhall became a bomber station, flying Vickers Wellingtons, Short Stirlings and Avro Lancasters. It was also the headquarters of 3 Group Bomber Command. From 1950, Mildenhall became home to bombers and later tanker aircraft of the United States Air Force. Throughout the 1950s, Strategic Air Command bomber units were deployed on a regular rotational basis from the United States to the United Kingdom. The B-47 Stratojet was a familiar sight in the skies over RAF Mildenhall and RAF Upper Heyford at this time, as entire wings deployed on 90-day rotations. From 1976 to 1990, the SR-71 Blackbird was flown out of Mildenhall by Detachment 4 of the 9th Strategic Reconnaissance Wing of the USAF. RAF Mildenhall was, until 2003, the home of the largest military-sponsored air show in Europe, when it was cancelled because of increasing operational requirements.
 Passage 2:Brabham replaced Schenken with Argentinian Carlos Reutemann for 1972. Hill remained with the team, but Brabham put the Argentinian in the BT34. The 1972 Argentine Grand Prix saw Reutemann take pole in his first grand prix but finish seventh. The Argentinian retired from South Africa with fuel system failure. Reutemann broke his ankle after a mechanical failure on his Rondel Racing entered Brabham at Thruxton during a Formula Two race. The BT34 was not used at the Spanish and Monaco Grands Prix. For Belgium, Brabham entered a third car for Brazilian Wilson Fittipaldi, but he retired with a broken gearbox. The Brazilian finished eighth at the French Grand Prix. Fittipaldi finished 12th at Britain despite having stopped the car on lap 69 with broken suspension. The Brazilian finished seventh at the German Grand Prix. Fittipaldi retired from the final four races of the year, brake failure at Austria, broken suspension in Italy, broken gearbox at Canada and engine failure at the United States.
 Passage 3:In July 1952, Loring transferred to the 36th Fighter-Bomber Squadron full-time, where he served as operations officer. In this role he returned to combat duty, this time as a jet aircraft fighter pilot operating the F-80 Shooting Star. Missions for this unit primarily concerned close air support, air strikes and interdiction missions supporting United Nations Command ground troops in the country. In this role, Loring's unit primarily fought North Korean and Chinese ground targets. By November 22, 1952, Loring had completed 50 combat missions. At that time the ground battle in Korea had developed into a stalemate, with the two sides firmly entrenched along the 38th Parallel. Throughout November, the UN forces had been launching Operation Showdown against two targets: Triangle Hill and Sniper Ridge, northwest of Kunwha, north of the 38th Parallel. During the battle, the Chinese managed to amass 133 large caliber guns, 24 BM-13 rocket launchers and 47 anti-aircraft guns in the largest Chinese artillery operation during the Korean War, and it posed a serious threat to ground troops of the ROK 2nd Infantry Division operating in the area. The artillery was heavily guarded, forcing the UN forces to use airpower to combat them.
