Given the task definition, example input & output, solve the new input case.
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: 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.

New input case for you: Question: How old was Scotty Moore when Richards partnered with him for All the King's Men? Passage 1:The San Francisco Estuary is a major stop on the Pacific flyway for migrating waterfowl. Yet little is known about the flow of carbon in or out of the estuary via birds. Millions of waterfowl annually use the bay shallows as a refuge. Most of the birds are dabbling ducks that feed on submerged aquatic vegetation. Diving ducks (such as scaups) feed on epibenthic organisms like C. amurensis, representing a possible flow of carbon from that otherwise dead end. Two endangered species of birds are found here: the California least tern and the California clapper rail. Exposed bay muds provide important feeding areas for shorebirds, but underlying layers of bay mud pose geological hazards for structures near many parts of the bay perimeter. Piscivorous birds such as cormorants and pelicans also inhabit the estuary, but their trophic impact remains poorly studied.
 Passage 2:In the 1990s and 2000s Richards continued to contribute to a wide range of musical projects as a guest artist. A few of the notable sessions he has done include guitar and vocals on Johnnie Johnson's 1991 release Johnnie B. Bad, which he also co-produced; and lead vocals and guitar on "Oh Lord, Don't Let Them Drop That Atomic Bomb on Me" on the 1992 Charles Mingus tribute album Weird Nightmare. He duetted with country legend George Jones on "Say It's Not You" on the Bradley Barn Sessions (1994); a second duet from the same sessions, "Burn Your Playhouse Down", appeared on Jones' 2008 release Burn Your Playhouse Down – The Unreleased Duets. He partnered with Levon Helm on "Deuce and a Quarter" for Scotty Moore's album All the King's Men (1997). His guitar and lead vocals are featured on the Hank Williams tribute album Timeless (2001) and on veteran blues guitarist Hubert Sumlin's album About Them Shoes (2005). Richards also added guitar and vocals to Toots & the Maytals' recording of "Careless Ethiopians" for their 2004 album True Love, which won the Grammy Award for Best Reggae Album. Additionally, in December 2007 Richards released a download-only Christmas single via iTunes of "Run Rudolph Run"; and the B-side was a 2003 recorded version of the famous reggae song "Pressure Drop" featuring Toots Hibbert singing with Richards backed by original Maytals band members Jackie Jackson and Paul Douglas.
