Task: Question Generation
Input (English): Passage: The Browns played their home opener against the Kansas City Chiefs looking to bounce back from a close loss in Week 1 against the Buccaneers. With starting QB Jake Delhomme out with an ankle injury, Seneca Wallace started the game for the Browns. Chiefs K Ryan Succop started the scoring with an early field goal. In the second quarter, the Browns scored on a 1-yard run by RB Peyton Hillis, but soon gave the lead back on an interception returned by CB Brandon Flowers. However, the Browns took a 14-10 lead into halftime on a deep touchdown pass from Wallace to WR Josh Cribbs. After the half, the Browns' offense stalled, and Succop kicked two more field goals to give the Chiefs a 16-14 victory.
Output (English): How many defensive touchdowns were scored?
