Task: Question Generation
Input (English): Passage: Coming off their dominant win over the 49ers, the Broncos remained on home ground for an AFC West duel against the San Diego Chargers on Thursday Night Football. After a scoreless first quarter, a 2-yard touchdown pass from quarterback Peyton Manning to wide receiver Emmanuel Sanders gave the Broncos the lead early in the second quarter. After the two teams traded punts on their next possessions, the Chargers tied the game with a time-consuming drive, culminating with 2-yard touchdown pass from quarterback Philip Rivers to wide receiver Keenan Allen. On the ensuing kickoff, Chargers' linebacker Kavell Conner forced a fumble off Broncos' return specialist Andre Caldwell, and it was recovered by Chargers' tight end Ladarius Green deep in Broncos' territory. However, it was overturned after an instant replay review. The Broncos then re-claimed the lead just before halftime, with another touchdown pass from Manning to Sanders &#8212; from 31 yards out. On the Chargers' opening possession of the second half, Rivers was intercepted by Broncos' cornerback Chris Harris, Jr., and six plays later, the Broncos added to their lead, with Manning throwing his third touchdown pass to Sanders &#8212; from 3 yards out. After the Broncos' defense forced a Chargers' punt, the Broncos increased their lead to 28-7 midway through the third quarter, with running back Juwan Thompson rushing for a 2-yard touchdown. The Chargers responded on their next possession, with a 4-yard touchdown pass from Rivers to tight end Antonio Gates on 4th-and-goal. The Broncos countered early in the fourth quarter, with Thompson rushing for a 1-yard touchdown. The drive was kept alive by a defensive holding penalty on Chargers' safety Marcus Gilchrist that negated an Eric Weddle interception of Manning near the goal line. The Chargers once again had a response, with another touchdown pass from Rivers to Gates &#8212; from 10 yards out. The Broncos tried to add to their lead on their next possession, however, placekicker Brandon McManus missed on a 53-yard field goal attempt. The Chargers attempted a rally, but Rivers was intercepted by Broncos' safety Rahim Moore near the goal line with five minutes remaining in the game. The Broncos' offense then ran out most of the clock, aided by a crucial 5-yard pass completion from Manning to wide receiver Wes Welker on 3rd-and-4 from their own 10-yard line that forced the Chargers to burn the last two of their three team timeouts, sealing the win for the Broncos.
