Task: Question Generation
Input (English): Passage: After a convincing win over a struggling Redskins team in Week 7, the Colts faced one of their toughest opponents of the year in the Denver Broncos. The Broncos sat atop the AFC West standings with a 5-1 record thanks in large part to a strong running game and a dominating defense that had only allowed two touchdowns on the season. Both defenses played well in the first quarter, which ended with the Colts leading 3-0. Denver took the lead early in the second quarter on a Jake Plummer one-yard touchdown run. Indianapolis cut the lead to one on their next drive, which ended in a 30-yard Adam Vinatieri field goal, but the Broncos answered with a 15-yard touchdown pass from QB Jake Plummer to WR Javon Walker just before halftime to expand their lead to 14-6. On their first drive of the half Indianapolis came within one point of the lead on a 12-yard touchdown pass from QB Peyton Manning to WR Reggie Wayne. On the Colts' next possession, Wayne and Manning hooked up again for another touchdown, this one a 5-yard TD pass to take the lead 20-14. But the Broncos came back with a one-yard touchdown run by Mike Bell, giving them a one-point lead at the end of the third quarter. After a Vinatieri field goal and another Denver touchdown, the Colts were down by 5 points with a little over half of the fourth quarter remaining. After the Colts received the kickoff, they marched down the field. The drive ended with a 19-yard touchdown pass from Manning to Wayne, the third time they hooked up for a touchdown in the game. The Colts were now up by one point and decided to go for the two-point conversion to go up by a field goal. The conversion was a success as Manning found Reggie Wayne in the end zone again. Jason Elam came through for Denver and made a 49-yard field goal to tie the game at 31. The final drive of the game resulted in an Adam Vinatieri field goal with two seconds left to put Indianapolis up by three. Manning ended the game with three touchdown passes, all of them to Reggie Wayne. Rookie RB Joseph Addai had a career-high 93 yards rushing on only 17 carries. DE Dwight Freeney was credited with half a sack, his first of the season.
Output (English): What type of score caused the game to tie at 31?
