Task: Question Answering
Input (English): Passage: The Steelers entered their first matchup with the Cleveland Browns having won 15 of the last 16&#160;games between the two teams. Ben Roethlisberger started the game despite missing practice time during the week due to a shoulder injury suffered in Week One. The Steelers' defense held the Browns to 16&#160;yards on their first four drives, as the teams played to a scoreless tie after the first quarter. After a Bryant McFadden interception the Steelers drove 70&#160;yards and Roethlisberger connected with Hines Ward for their third touchdown combination of the season. Cleveland responded with a 14&#160;play, 71&#160;yard drive, but Troy Polamalu intercepted a Cleveland pass as time expired in the first half solidifying Pittsburgh's seven point halftime lead. A 48-yard pass from Roethlisberger to Santonio Holmes and a 48-yard field goal from Jeff Reed on the team's second drive of the second half brought the score to 10-0. The Browns' Phil Dawson converted two consecutive field goals, to pull Cleveland within four points with 3:21&#160;remaining. After a fourth down stop, Cleveland's offense took over with 26&#160;seconds remaining, but failed to gain yardage as time expired. With the win, the Steelers increased their win streak over the Browns to 10&#160;consecutive games&#8212;the longest current winning streak over a single opponent in the NFL. With the win the Steelers improved to 2-0 and led the AFC North by 1/2 a game ahead of the Ravens.
