Task: Question Generation
Input (English): Passage: at M&T Bank Stadium, Baltimore, Maryland TV Time: CBS 1:00pm eastern The Chargers went to Baltimore for the first time since 2000. The Chargers led down the field first with a 31-yard touchdown pass to WR Malcom Floyd. However, this was followed two drives later by an interception by OLB Bart Scott (who was named September's Defensive Player of the Month recently before the game), which led to a 5-yard touchdown pass from QB Steve McNair to TE Daniel Wilcox. In the second quarter, 2 Chargers field goals from kicker Nate Kaeding put San Diego in the lead at the half. In the third quarter, the Ravens' defense held the Chargers to no points. They were assisted by a loud stadium, which led to a fourth quarter intentional safety by Chargers punter Mike Scifres. The Ravens took the ball at the 40-yard line with 3:12 to go. After Derrick Mason dropped a possible touchdown pass early in the drive, a 10-yard pass to TE Todd Heap won the game with 30 seconds to play. On the touchdown catch, Heap broke a tackle from Shawne Merriman. With the win, the Ravens were 4-0 for the first time in their 11-year history. However, Guard Edwin Mulitalo was injured for the entire season with a triceps injury.
