Task: Question Generation
Input (English): Passage: Hoping to rebound from their road loss to the Falcons, the Lions played their Week 2 home opener against their NFC North foe, the Green Bay Packers. In the first quarter, Detroit trailed as Packers QB Aaron Rodgers completed a 9-yard TD pass to WR James Jones.  In the second quarter, the Lions continued to trail as Rodgers completed a 2-yard TD pass to WR Donald Driver and a 29-yard TD pass to WR Jordy Nelson.  Detroit closed out the first half when kicker Jason Hanson nailed a 38-yard field goal. In the third quarter, the Lions continued to hack away at Green Bay's lead with Hanson kicking 49-yard and then 53-yard field goals. The Packers responded when kicker Mason Crosby nailed a 25-yard field goal. In the fourth quarter, Detroit clawed away at the Pack's lead when QB Jon Kitna completed a 38-yard TD pass to WR Calvin Johnson. The Lions closed in as the snap to Packers punter Derrick Frost was high, causing it to go through the back of his end zone, giving Detroit a safety. The Lions took the lead on Kitna's 47-yard TD pass to Calvin Johnson.  However, Green Bay rebounded with Crosby's 39-yard field goal, RB Brandon Jackson's 19-yard TD run, CB Charles Woodson's 41-yard interception return for a touchdown, and safety Nick Collins' 42-yard interception return for a touchdown.
Output (English): Which team gave away a safety in the fourth quarter?
