Instructions: 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.
Input: Question: When did the expedition that John Colter was apart of in 1807 begin? Passage 1:Bobby Ross coached the Chargers from 1992 to 1996, and is the only coach to win awards while coaching the Chargers. In 1992, Ross won the Pro Football Weekly NFL Coach of the Year, the Maxwell Football Club NFL Coach of the Year and the UPI NFL Coach of the Year. The Pro Football Weekly NFL Coach of the Year is presented annually by various news and sports organizations to the National Football League (NFL) head coach who has done the most outstanding job of working with the talent he has at his disposal. The Maxwell Football Club NFL Coach of the Year was created in 1989 and is originally titled the Earle "Greasy" Neale Award for Professional Coach of the Year. The United Press International (UPI) NFL Coach of the Year award was first presented in 1955. Before the AFL-NFL merger, an award was also given to the most outstanding coach from the AFL. When the leagues merged in 1970, separate awards were given to the best coaches from the AFC and NFC conferences. The UPI discontinued the awards after 1996.
 Passage 2:Suffocation was formed in 1988 on Long Island, New York, by vocalist Frank Mullen, guitarists Guy Marchais and Todd German, bassist Josh Barohn, and an unknown drummer. By 1990, the band had hired guitarists Terrance Hobbs and Doug Cerrito along with drummer Mike Smith, who were members of a local band called Mortuary, which had already disbanded. The quintet was mainly influenced by fellow American death metal bands as well as the British band Napalm Death and Brazilian Sepultura. Smith commented on meeting Hobbs for the first time: "That's where I first noticed, 'Wow, theres another black guy playing this kind of stuff'". The band's first EP, Human Waste, was released through Relapse Records in 1991. The full-length debut album, Effigy of the Forgotten, recorded by producer Scott Burns at Tampa's Morrisound Studios and released by Roadrunner Records the same year. In July 1991, Barohn was replaced by Chris Richards, as the album became substantially influential in extreme metal music.
 Passage 3:Europeans may have ventured into the northern sections of the state in the late 18th century. Most of the southern part of modern-day Wyoming was nominally claimed by Spain and Mexico until the 1830s, but they had no presence. John Colter, a member of the Lewis and Clark Expedition, was probably the first American to enter the region in 1807. His reports of thermal activity in the Yellowstone area were considered at the time to be fictional. Robert Stuart and a party of five men returning from Astoria, Oregon discovered South Pass in 1812. The route was later followed by the Oregon Trail. In 1850, Jim Bridger located what is now known as Bridger Pass, which was later used by both the Union Pacific Railroad in 1868, and in the 20th century by Interstate 80. Bridger also explored the Yellowstone region and like Colter, most of his reports on that region of the state were considered at the time to be tall tales. During the early 19th century, fur trappers known as mountain men flocked to the mountains of western Wyoming in search of beaver. In 1824, the first mountain man rendezvous was held in Wyoming. The gatherings continued annually until 1840, with the majority of them held within Wyoming territory.
