question:
Passage: After a punt from both teams, Carolina got on track with a 9-play, 73-yard scoring drive. Newton completed 4 of 4 passes for 51 yards and rushed twice for 25 yards, while Jonathan Stewart finished the drive with a 1-yard touchdown run, cutting the score to 10–7 with 11:28 left in the second quarter. Later on, Broncos receiver Jordan Norwood received Brad Nortman's short 28-yard punt surrounded by Panthers players, but none of them attempted to make a tackle, apparently thinking Norwood had called a fair catch. Norwood had not done so, and with no resistance around him, he took off for a Super Bowl record 61-yard return before Mario Addison dragged him down on the Panthers 14-yard line. Despite Denver's excellent field position, they could not get the ball into the end zone, so McManus kicked a 33-yard field goal that increased their lead to 13–7. Question: Who scored the Panthers first touchdown? 
answer:

Jonathan Stewart
