Task: Question Generation
Input (English): Passage: Coming off an upset win over the Green Bay Packers, the Steelers hosted the Baltimore Ravens in their second matchup of the season.  There was much at stake, as the Ravens needed to win to get into the playoffs, and the Steelers needed to win in order to keep their faint playoff hopes alive as well. Jeff Reed booted 26-yard and 39-yard field goals and Billy Cundiff kicked a 27-yarder to give the Steelers a 6-3 lead as they started the second quarter.  The Steelers offense would start rolling, scoring on a 4-yard run by Rashard Mendenhall. Joe Flacco responded with a 30-yard TD pass to Todd Heap. But in the final seconds of the first half, Ben Roethlisberger found Santonio Holmes for a 24-yard TD pass, and the Steelers carried a 20-10 lead with them into halftime. Baltimore controlled the third quarter.  Flacco hit Heaps for a seven-yard TD pass and Cundiff kicked a 35-yard field goal to tie the game. The fourth quarter saw both defenses step up.  Jeff Reed kicked a 38-yard field goal with 5:25 remaining to give the Steelers a 23-20 lead.  Baltimore had one more chance to score, but rookie defensive end Ziggy Hood recorded his first career sack and then recovered Flacco's fumble on a fourth and 10 play from the Steelers' 39 with 2:27 remaining. An apparent interception thrown by Roethlisberger was negated by an "illegal block in the back" penalty and the Steelers ran out the clock, securing the win. The win not only prevented Baltimore from clinching a wild card, but kept Pittsburgh's playoff hopes alive as well. They would need to win at Miami in their season finale and also need other teams to lose.
Output (English): How many touchdown passes did Joe Flacco throw?
