Task: Question Generation
Input (English): Passage: Coming off their divisional home win over the Rams, the 49ers flew to Texas Stadium for a Week 12 game with the throwback-clad Dallas Cowboys.  In the first quarter, the Niners struck first as kicker Joe Nedney got a 23-yard and a 22-yard field goal.  In the second quarter, the Cowboys took the lead as QB Tony Romo completed a 75-yard TD pass to former 49ers WR Terrell Owens.  Dallas continued its domination as LB Carlos Polk blocked punter Andy Lee's punt into the back of the endzone for a safety.  The Cowboys closed out its period of power as kicker Nick Folk got a 48-yard and a 41-yard field goal, along with Romo completing a 1-yard TD pass to TE Martellus Bennett. In the third quarter, Dallas increased its lead with Romo completing a 10-yard TD pass to WR Patrick Crayton.  San Francisco tried to rally as Nedney got a 35-yard field goal.  In the fourth quarter, the Cowboys answered with Folk getting a 47-yard field goal.  The 49ers tried to come back as QB Shaun Hill completed an 18-yard TD pass to WR Isaac Bruce, but Dallas replied with Folk nailing a 42-yard field goal.  The Niners tried to rally as Hill completed a 9-yard TD pass to RB DeShaun Foster, but that would be as close as San Francisco's comeback would get.
Output (English): How many yards shorter was Joe Nedney's second field goal compared to his first?
