Task: Question Generation
Input (English): Passage: The Saints opened the regular season on the road against the Cleveland Browns on September 10.  In the first half, kicker John Carney provided all of the Saints' first 9 points.  He put up a 43-yarder in the first, along with a 25 and a 21-yarder in the second quarter.  In the third quarter, the Browns offense finally got going as Cleveland quarterback Charlie Frye hooked up with TE Kellen Winslow on an 18-yard touchdown pass.  Fortunately, the Saints would respond with a 12-yard touchdown pass from quarterback Drew Brees to WR Marques Colston.  In the fourth quarter, the Browns came close with Frye getting a 1-yard touchdown run.  However, the Saints put the game away with Carney kicking a 20-yard FG to give the Saints the win. Despite not scoring a touchdown, RB Reggie Bush had a sound NFL debut, as he ran 14 times for 61 yards, caught 8 passes for 58 yards, and returned three punts for 22 Yards.  In total, he piled up 141 all-purpose yards.
Output (English): How many field goals did Carney kick at halftime?
