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.

Let me give you an 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.

Question: Who was the older, John C. Jacobs or his predecessor? Passage 1:He served aboard the submarines HMS Porpoise and HMS Thrasher earning the Distinguished Service Cross for his service in the latter in 1942. As commanding officer of the submarine HMS Sceptre he sank almost 15,000 tons of enemy shipping and took part in Operation Source, the attacks on heavy German warships in Norwegian waters by towed midget submarines. He commanded the submarine HMS Alderney from 1946, the submarine HMS Aeneas from 1950 and then the aircraft carrier in the 1960s. He became Director-General Weapons (Naval) at the Ministry of Defence in 1969 and Deputy Chief of the Defence Staff (Operational Requirements) in 1970 before retiring in 1973.
 Passage 2:In early September 1914, 18-year old Lewis attended a recruitment meeting organised by a Major Birt, who was also his father's employer, which drew crowds of 2000–3000 people before enlisting in the 11th (Service) Battalion of the Welsh Regiment which had been formed little over a month before as the Cardiff Commercial Battalion, a pals unit. At 10 a.m. the next day, Lewis, was one of 75 local volunteers who left Milford Haven before being split into smaller groups with Lewis and 45 others travelling to Maindy Barracks in Cardiff, the rest joining the Royal Engineers or the Royal Artillery. Two days later, his unit was moved to Lewes as part of the 67th Brigade. He also underwent training at Eastbourne, Hastings, Aldershot and Seaford. On 5 September 1915, just over a year after enlisting, Lewis and his unit sailed to Boulogne, France from Southampton. Several days after his arrival, he was attached to the 9th Border Regiment as a machine gunner.
 Passage 3:The caucus of Democratic State legislators met on January 15, State Senator Albert P. Laning, of Buffalo, presided. All but one of the legislators were present, only Assemblyman John M. Roscoe, of Schoharie County, was sick. The caucus nominated Francis Kernan for the U.S. Senate. Kernan had been the Democratic/Liberal Republican candidate for Governor in November 1872 but had been defeated by John Adams Dix. Now Kernan was the choice of Tammany boss John Kelly who had succeeded the corrupt William M. Tweed. Kelly was opposed by John C. Jacobs, who proposed Ex-State Senator Henry C. Murphy, Jacobs's predecessor from the 3rd District, and the Democratic candidate who had lost the U.S. Senate elections in 1867 and 1869 when the Democrats were the minority. Kelly stood firm in his intention to dominate the Democratic Party, and had the caucus nomination made by viva voce vote instead of the more traditional secret ballot. Jacobs and Murphy had expected to get votes from many legislators who would not dare to cross Kelly openly, but had to abandon their hopes when the secret ballot was voted down 74 to 13.
