Question: Which team has more NFC Championship wins, the Green Bay Packers or the Minnesota Vikings? Passage:In his first season in 1997, the 49ers went during the regular season, earning home-field advantage in the playoffs in the National Football Conference (NFC). After defeating the Minnesota Vikings in the divisional round, San Francisco hosted the Green Bay Packers in the NFC Championship Game, but in a muddy, rainy contest at Candlestick Park. The defeat was the 49ers' fourth NFC title loss of the 1990s, following losses to the New York Giants in 1990 and the Dallas Cowboys in 1992 and 1993, and it was their third playoff loss to the Packers in as many seasons. In 1998, the 49ers posted a 12–4 record and returned to the playoffs as a wild-card team, but to the eventual NFC champion Atlanta Falcons. Two losing seasons followed, but in 2001, the 49ers returned to the playoffs after season, once again to be eliminated by the Packers.

Question: What are earthwork mounds made of? Passage:Indigenous peoples inhabited Missouri for thousands of years before European exploration and settlement. Archaeological excavations along the rivers have shown continuous habitation for more than 7,000 years. Beginning before 1000 CE, there arose the complex Mississippian culture, whose people created regional political centers at present-day St. Louis and across the Mississippi River at Cahokia, near present-day Collinsville, Illinois. Their large cities included thousands of individual residences, but they are known for their surviving massive earthwork mounds, built for religious, political and social reasons, in platform, ridgetop and conical shapes. Cahokia was the center of a regional trading network that reached from the Great Lakes to the Gulf of Mexico. The civilization declined by 1400 CE, and most descendants left the area long before the arrival of Europeans. St. Louis was at one time known as Mound City by the European Americans, because of the numerous surviving prehistoric mounds, since lost to urban development. The Mississippian culture left mounds throughout the middle Mississippi and Ohio river valleys, extending into the southeast as well as the upper river.
