Task: Question Generation
Input (English): Passage: The Raiders off-field fortunes have varied considerably over the years. The teams first three years of operation (1960 Oakland Raiders season–1962 Oakland Raiders season) were marred by poor on-field performance, financial difficulties, and spotty attendance. In 1963 Oakland Raiders season, however, the Raiders fortunes improved dramatically with the introduction of head coach (and eventual owner) Al Davis. In 1967 Oakland Raiders season, after several years of improvement, the Raiders reached the postseason for the first time. The team would go on to win its first (and only) 1967 American Football League Championship Game that year; in doing so, the Raiders advanced to Super Bowl II, where they were soundly defeated by the Green Bay Packers. Since 1963, the team has won 15 division titles (three AFL and 12 NFL), four AFC Championships (1976–77 NFL playoffs, 1980–81 NFL playoffs, 1983–84 NFL playoffs, and 2002–03 NFL playoffs), one AFL Championship (1967 American Football League Championship Game), and three Super Bowl Championships (Super Bowl XI, Super Bowl XV, and Super Bowl XVIII). At the end of the NFLs 2017 NFL season, the Raiders boasted a lifetime regular season record of 462 wins, 411 losses, and 11 ties; their lifetime playoff record currently stands at 25 wins and 19 losses.
Output (English): How many years after they began operation did the Raiders win the American Football League Championship Game?
