Task: Question Generation
Input (English): Passage: The Bills scored first on a 74-yard kick return by Roscoe Parrish.  Denver then answered with a 10 play drive that led to a field goal by Jason Elam, making it 7-3. In the second quarter Denver scored first with a 48-yard field goal.  Bills kicker Rian Lindell then missed a 45-yard field goal.  The Broncos drove deep into Bills territory at the close of the half but Cutler threw an interception to end the drive.  The Bills then drove into Denver territory and tried a long field goal but failed due to a false start, then ended the half with an interception thrown to Elvis Dumervil. On the opening kickoff for the second half, a scary injury occurred to Bills TE Kevin Everett, as he suffered a cervical spine injury while making a tackle on Domenik Hixon. Everett later underwent surgery that day and is currently in intensive care.  He does have feeling and partial movement in his extremities and it is believed he will walk again. The Broncos began the second half with a drive that ended with a missed 50-yard field goal.  The Bills then made a nine play drive that ended with a 23-yard touchdown run by Marshawn Lynch.  The Broncos responded with a drive ending with a touchdown pass to Brandon Marshall.  They then attempted to tie the game with a two-point conversion but failed with an incomplete pass to Javon Walker. The fourth quarter had little scoring.  Elam missed a field goal, but the Bills failed to score or run out the clock, giving Denver the ball with a little over two minutes to play. After an ill-advised lateral bounced free, (saved by rookie back Selvin Young smartly batting the loose ball out of bounds) the Bronco's faced a seemingly insurmountable 3rd and 23 to go. Cutler immediately turned in the best clutch performance of his NFL career to date, one that drew comparisons to John Elway by both sportswriters and teammates. Cutler's drive included two fourth down conversions to drive deep into Bills' territory, where, with no time outs, they rushed the field goal unit onto the field with ten seconds left and the clock ticking down. Execution by the field goal unit allowed Jason Elam to kick the game winning 42-yard field goal just as the clock ticked to 0:00.  Buffalo ended up leading the game for over 51 minutes of the contest.  Denver lead for one second.
Output (English): How many points were the Bills ahead by in the first quarter?
