Q: Question: When did the expedition that John Colter was apart of in 1807 begin? Passage: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.

Q: Question: How many teams were a part of the league that ran from 2001-2003 and featured many World Cup stars? Passage:The first women's professional soccer league in the U.S. formed after the success of the 1999 Women's World Cup. The Women's United Soccer Association (WUSA) ran from 2001–2003 and featured many of the World Cup stars, including Mia Hamm, Michelle Akers and Brandi Chastain. Its successor Women's Professional Soccer (WPS) ran from 2009–2012. Currently, the National Women's Soccer League (NWSL) is the top professional league in the country and was formed in 2012. The NWSL season runs from spring to early fall (typically April – October). In 2017, A&E Networks bought an equity stake in the league and broadcasts a game of the week on Lifetime, and formerly streamed all games online via the go90 platform. During the 2018 season, the NWSL moved some of the games originally scheduled to air on Lifetime to evening slots on ESPNews (both channels being part of the Disney family), and when go90 owner Verizon shut down that platform at the end of July, the NWSL streamed the games that were intended for go90 on its own website.

Q: Question: What year was the defensive tackle that was used as a running back born? Passage:Mike Ditka, a tight end for the Bears from 1961 to 1966, was hired to coach the team by George Halas in 1982. His gritty personality earned him the nickname "Iron Mike". The team reached the NFC Championship game in 1984. In the 1985 season the fire in the Bears–Packers rivalry was re-lit when Ditka used 315 pound defensive tackle "Refrigerator" Perry as a running back in a touchdown play at Lambeau Field, against the Packers. The Bears won their ninth NFL Championship, first since the AFL-NFL merger, in Super Bowl XX after the 1985 season in which they dominated the NFL with their then-revolutionary 46 defense and a cast of characters that recorded the novelty rap song "The Super Bowl Shuffle". The season was notable in that the Bears had only one loss, the "unlucky 13th" game of the season, a Monday night affair in which they were defeated by the Miami Dolphins. At the time, much was made of the fact that the Dolphins were the only franchise in history to have had an undefeated season and post-season. The Dolphins came close to setting up a rematch in the Super Bowl, but lost to the New England Patriots in the AFC title game. "The Super Bowl Shuffle" was videotaped the day after that Monday night loss in Miami.
