Question: Question: What year did the Steelers appear in their first Super Bowl? Passage:The Pittsburgh Steelers compete in the National Football League (NFL) as a member club of the American Football Conference (AFC) North division. Founded in 1933, the Steelers are the oldest franchise in the AFC; seven franchises in the National Football Conference (NFC) have longer tenures in the NFL. The team struggled to be competitive in its early history, posting winning records in just 8 of its first 39 seasons. Since the AFLNFL merger in 1970, however, it has appeared in eight Super Bowls and one of only two teams, along with the New England Patriots have won the Super Bowl six times. The six championships place the Steelers fourth in the league in terms of total championships (including those prior to the first Super Bowl), trailing only the Green Bay Packers (13 championships), the Chicago Bears (9) and the New York Giants (8). The club's 15 AFC Championship Game appearances are second all-time, behind the Patriots (16). In addition, they have hosted the second-most conference championship games (11) than any franchise in either conference, and are tied for second with the Dallas Cowboys and Denver Broncos with eight Super Bowl appearances; the Patriots currently hold the record of eleven appearances, as of 2019.

Answer: Since the AFLNFL merger in 1970, however, it has appeared in eight Super Bowls and one of only two teams, along with the New England Patriots have won the Super Bowl six times

Question: Question: Do fewer than 10,000 people inhabit the town near the Oscarsborg Fortress? Passage:Meanwhile, at Oscarsborg Fortress near Drbak, Colonel Birger Eriksen prepares his undermanned and inexperienced garrison for combat, while receiving reports from the outlying fortresses of incoming German ships. Early on the morning of 9 April, Eriksen spots the German cruiser Blucher entering Drbak Sound. Despite having received no instructions from Oslo to engage, Eriksen considers the German ship to be hostile and gives the order to fire, and the fortress's guns and torpedo battery sink the Blucher. Prime Minister Nygaardsvold telephones the King, informing him of the impending invasion, and advises him to flee Oslo. The Royal Family boards a train for Hamar, where the Norwegian Parliament convenes to discuss negotiations with Germany. Brauer meets Oslo's police chief Kristian Welhaven, his intermediary with the Norwegian Cabinet, to reassure them of his desire to negotiate; at the same time, Pohlman receives orders from Berlin to send paratroopers to Hamar to capture the King and the Cabinet. Nasjonal Samling leader Vidkun Quisling proclaims himself Prime Minister over the national radio, and calls upon the Norwegian people to accept the German occupation forces. Brauer receives instructions from Hitler himself to go directly to the King and convince him to recognise Quisling's government, though Brauer is convinced that neither Haakon nor the Cabinet will accept this.
