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: How many cities with a population greater than 1,000,000 did Idaho have the year Walker won the Cowboy Capital of the World Rodeo? Passage 1:Talladega Superspeedway, originally known as Alabama International Motor Superspeedway (AIMS), is a motorsports complex located north of Talladega, Alabama. It is located on the former Anniston Air Force Base in the small city of Lincoln. The track is a tri-oval and was constructed in the 1960s by the International Speedway Corporation, a business controlled by the France Family. Talladega is most known for its steep banking and the unique location of the start/finish line that's located just past the exit to pit road. The track currently hosts the NASCAR series such as the Sprint Cup Series, Xfinity Series and the Camping World Truck Series. Talladega is the longest NASCAR oval with a length of tri-oval like the Daytona International Speedway, which also is a tri-oval.
 Passage 2:In 2013, Walker continued to compete, winning the Cowboy Capital of the World Rodeo in Stephenville, Texas, the Pasadena Livestock Show and Rodeo, in Pasadena, Texas, the Champions Challenge, in Kissimmee, Florida, the Walla Walla, Washington, the Frontier Days Rodeo, the Sanders County Fair & Rodeo in Plains, Montana, the Jerome County Fair & Rodeo in Idaho, the Montana’s Biggest Weekend in Dillon, Montana, the Ogden Pioneer Days Rodeo in Utah, the Eagle County Fair & Rodeo in Colorado, the Rocky Pro Rodeo in Rocky Mountain House, Alberta, the Pony Express Days Rodeo, in Eagle Mountain, Utah, the inaugural Champions Challenge in Redding, California, the San Angelo Stock Show and Rodeo in San Angelo, Texas, and the 75th Annual Brighton Field Day Festival & Rodeo in Okeechobee, Florida. Her money winnings qualified her again for the NFR, where she placed in 7 out of 10 rounds at the 2013 finals. She placed 6th in the average, and finished as the reserve world champion. She won $92,248. She was inducted into the National Cowgirl Museum and Hall of Fame this year. 
 Passage 3:"Online" is a moderate up-tempo song whose lyrics satirize the online world, specifically MySpace. Here, the song's protagonist is a geek who lives at home with his parents, holds a job at the local Pizza Pitt pizzeria, and claims limited success in the dating world. Actually "five-foot-three and overweight", a fan of science fiction, and a mild asthmatic, the main character has an account on MySpace. There, he assumes a much more desirable personality: "Online, I'm out in Hollywood / I'm six-foot-five and I look damn good / I drive a Maserati / I'm a black-belt in karate / And I love a good glass of wine". Later in the song, he claims to live in Malibu, California, have a sexy, finely sculptured body, and pose for Calvin Klein Inc. and GQ. The fictitious alternate personalities make the geek claim that he is "so much cooler online". The album version of the song ends with a marching band playing the melody of the chorus, a reference to an earlier line where the protagonist claims to play tuba in a marching band.
