Task: Question Answering
Input (English): Passage: The game would start with a Rob Bironas field goal to take a 3 nothing lead. However, to end the first half, Tennessee was holding the defending NFC champs 6-3, but an extended play with 5 seconds left on Arizona's 20 or so, would diminish Tennessees chances for a field goal. Tennessee scored the first touchdown during the second half to take a 13-3 lead, but Arizona scored 14 straight points with the help of Lerod Stevens-Howling returning a kickoff for a touchdown. Facing a 17-13 deficit at their own 1-yard line, Vince Young led the Titans on an 18 play drive which featured him throwing for 94 yards, running for 5 and converting three 4th downs including a 4th & goal to Kenny Britt as time expired for a touchdown to win 20-17.  The win improved the team to 5-6 and marked the first time in NFL history that a team won five-straight games after losing their first six.
