Task: Question Understanding
Input (English): Passage: Hoping to rebound from their overtime loss to the Patriots, the Broncos traveled to Arrowhead Stadium for an AFC West rematch with the Kansas City Chiefs. The Broncos and Chiefs entered the game tied for the AFC West division lead, both with 9-2 records. The Chiefs grabbed the lead late in the first quarter, with quarterback Alex Smith throwing a 17-yard touchdown pass to wide receiver Junior Hemingway. The Broncos responded at the beginning of the second quarter, with quarterback Peyton Manning throwing a 41-yard touchdown pass to wide receiver Eric Decker. However, Chiefs' running back Knile Davis returned the ensuing kickoff 108 yards for a touchdown, and following a Manning interception on the Broncos' next possession, Smith connected with tight end Anthony Fasano on a 12-yard touchdown pass to give the Chiefs a 21-7 lead. The Broncos then reeled off 28 unanswered points, beginning with a 3-yard touchdown pass from Manning to running back Knowshon Moreno. Manning then connected with Decker on three more touchdown passes &#8212; a 37-yarder and a 15-yarder in the third quarter, followed by a 1-yarder early in the fourth quarter. A 1-yard touchdown run by Chiefs' running back Jamaal Charles narrowed the Broncos' lead to 35-28 with 6:32 remaining in the fourth quarter, and the Chiefs' defense forced a punt on the Broncos' next possession. The Chiefs' offense had one last possession with 3:32 remaining in the fourth quarter, and Smith drove the Chiefs to as far as the Broncos' 13-yard line with 1:51 remaining. However, Broncos' safety Mike Adams deflected a fourth-down pass from Smith that was intended for wide receiver Dwayne Bowe near the goal line, and the Broncos' subsequently ran out the clock. With the win, the Broncos swept the Chiefs for a second consecutive season.
