Task: Question Answering
Input (English): Passage: Coming off their bye week, the Ravens flew to Heinz Field for a Monday Night divisional duel with the throwback-clad Pittsburgh Steelers.  In the first quarter, Baltimore fell behind early as Steelers QB Ben Roethlisberger completed a 17-yard TD pass to TE Heath Miller and a 15-yard TD pass to WR Santonio Holmes.  In the second quarter, the Ravens continued to struggle as Roethlisberger completed a 30-yard TD pass to WR Nate Washington, a 35-yard TD pass to Holmes, and 7-yard TD pass to Washington.  Afterwards, Baltimore got its only score of the game as RB Willis McGahee got a 33-yard TD run.  In the third quarter, Pittsburgh increased its lead with kicker Jeff Reed nailing a 22-yard field goal.  Afterwards, the Steelers' defense continued to shut down any hope of a comeback. The Ravens offense committed four turnovers and 11 penalties, and was held to a franchise-worst 104 total yards.  QB Steve McNair had a dismal night, as he completed 13 out of 22 passes for only 63 yards and an interception.
