Task: Question Understanding
Input (English): Passage: Carolina's Cam Newton made a successful comeback from a rib injury that kept him out of action in Week 1, but the story of the day was the Panthers' defense. Carolina forced three Detroit turnovers, two of which led to scores. Graham Gano opened the scoring for Carolina in the second quarter with field goals of 29 and 53 yards.  The Lions took a 7-6 lead in the third quarter when Matthew Stafford hit fullback Jed Collins with a 1-yard TD pass. But the rest of the game was all Carolina. Newton closed the third with a 14-yard TD pass to Jason Avant to retake the lead, 13-7. In the fourth quarter, Jonathan Stewart found the end zone on a 2-yard TD run, with the ensuing 2-point conversion giving the Panthers a 21-7 lead.  Gano finished the scoring with a 38-yard field goal.
