Task: Question Generation
Input (English): Passage: With the loss the Steelers dropped to 7-6 overall, 4-2 in home games, 1-3 against the AFC West, and 14-1 all-time at home against the San Diego Chargers despite Big Ben returning to the field from injury. They became the only AFC North team to lose to the Chargers, win less than three games against all four AFC West teams, and not win any of those matchups in regulation. With losses by the Ravens and Bengals on the same day, the AFC North title remains in sight for Pittsburgh, who will travel to Dallas next week to take on the Cowboys, a team they have faced three times out of their eight appearances in the Super Bowl. Both teams share the NFL-record number of Super Bowl appearances for a franchise, tied at eight, and remain the only two teams to face each other more than twice in Super Bowl matchups.
Output (English): How many Super Bowl appearances do the Steelers and Cowboys have combined?
