Task: Question Answering
Input (English): Passage: Hoping to rebound from their embarrassing home loss to the Lions, the Raiders flew to Invesco Field at Mile High for an AFC West duel with the Denver Broncos.  In the first quarter, Oakland trailed early as Broncos QB Jay Cutler completed a 9-yard TD pass to WR Brandon Stokley for the only score of the period.  In the second quarter, the Raiders got on the board with kicker Sebastian Janikowski getting a 38-yard field goal.  However, Denver continued to pound away as RB Cecil Sapp got a 4-yard TD run, while kicker Jason Elam got a 23-yard field goal. In the third quarter, Oakland began to come back as QB Josh McCown (who was a gametime decision heading into the game) completed a 46-yard TD pass to WR Jerry Porter for the only score of the period.  In the fourth quarter, the Raiders took the lead as DT Gerard Warren sacked Cutler in the end zone for a safety, while LB Thomas Howard returned an interception 44 yards for a touchdown (followed by a successful two-point conversion pass from McCown to WR Ronald Curry).  However, the Broncos tied the game up with Elam's 20-yard field goal.  In overtime, Oakland managed to make Denver go three-and-out on their first possession.  A 33-yard run by RB LaMont Jordan helped set up Janikowski for a game-winning 52-yard field goal. Broncos head coach Mike Shanahan called timeout before the kick could begin.  Janikowski's second try hit off the very tip of the left goal post and was no good, giving Denver a chance to win the game.  The Broncos won with Elam getting a 23-yard field goal. With the loss, not only did the Raiders fall to 0-2, but they had lost 11-straight games (currently the NFL's longest losing streak) dating back to Week 9 of the 2006 season. 
Question: How many field goals did Elam kick in the second quarter?
