Task: Question Understanding
Input (English): Passage:  Following a rare tie with the Minnesota Vikings 26-26 at Lambeau Field, the Packers travelled to Ford Field to take on the Detroit Lions on Thanksgiving football. Due to Matt Flynn's performance the previous week, he replaces Scott Tolzien and makes his first start for the Packers in the 2013 season. The Lions' opening possession ended at the Green Bay 12 when Clay Matthews forced a Reggie Bush fumble that was recovered by Morgan Burnett. However, the Packers could not capitalize, and the Lions drew first blood with a 27-yard field goal. Following a kickoff that went out-of-bounds, the Packers answered with a 54-yard field goal to tie it at 3-3. The Packers quickly struck again when Nick Perry forced a Matthew Stafford fumble that was returned by Morgan Burnett for a TD for a 10-3 lead. The Lions answered by scoring two TDs, first a 5-yard TD pass to Jeremy Ross, then a 1-yard run by Reggie Bush. Detroit had opportunities for more points before the half, but David Akers missed a 31-yard field goal as the 1st half expired, keeping a 17-10 lead. Following a 3-and-out on Green Bay's opening possession in the 3rd quarter, the Lions scored on a 20-yard TD pass to Calvin Johnson, extending their lead 24-10. Late in the 3rd quarter, Ndamukong Suh sacked Matt Flynn in the endzone, forcing a safety that made it 26-10. The Lions capitalized on their next possession with a 1-yard run by Joique Bell. They followed that up with a 20-yard TD pass to Kevin Ogletree, which extended their lead 40-10. The Packers tried to rally with a 56-yard pass to James Jones, but Matt Flynn fumbled the snap on the next play, and Detroit recovered and ran out the clock. This loss marked Matthew Stafford's first career win against the Packers. It also snapped the Lions' 10-year losing streak on Thanksgiving Day. With the loss, the Packers fell to 5-6-1.
