Task: Question Generation
Input (English): Passage: The Chargers rallied from a 21-point deficit, and Novak kicked the game-winning 40-yard field goal in overtime to defeat the San Francisco 49ers 38-35. Rivers, who sat out practice earlier in the week with back and chest injuries, overcame three interceptions to throw for 356 yards and four TDs. The Chargers, who played the game without injured offensive stars Allen and Mathews, outscored the 49ers 31-7 after halftime. The win kept San Diego's slim playoff chances alive. The 49ers led 28-7 at halftime, aided by a 49-yard TD return of a Rivers interception by Antoine Bethea. San Francisco rushed for 365 yards, the most the Chargers had surrendered since Adrian Peterson set a single-game record of 296 in 2007. Running back Frank Gore had 158, and quarterback Colin Kaepernick added 151, including a 90-yard TD run in the third quarter. In the fourth, Gates caught one of his two touchdowns in the second half, and Rivers connected with Floyd with 29 seconds remaining for the game-tying score, set up by two long fourth-down conversions earlier in the drive. The game went into overtime after 49ers kicker Phil Dawson missed a 60-yard field goal attempt at the end of regulation. On the opening drive in overtime, Weddle forced a fumble by receiver Quinton Patton, which was recovered by San Diego's Sean Lissemore. The Chargers drove, and Novak hit the game-winner nearly five minutes into the extra period. Rivers completed 33 of 54 passes in the game. The Chargers were playing with their fifth-string center, and rookie right guard Jeremiah Sirles was making his NFL debut. The offense converted all three of their fourth-down conversions after entering the game with the worst conversions rate at 20% (1-of-5). It was the 49ers fourth consecutive loss. It was only the second time ever that San Francisco had lost after leading by 21 or more at the half.
