Task: Question Understanding
Input (English): Passage: Trying to build on their win over the Cardinals, the Vikings flew to Soldier Field for an NFC North rematch with the Chicago Bears. After a scoreless first quarter, the Bears drew first blood in the second quarter with DB Devin Hester returning a punt 45 yards for a touchdown. Afterwards, Minnesota had kicker Ryan Longwell nail a 23-yard field goal. In the third quarter, Longwell would kick a 30-yard field goal, but that would be as close as the Vikings got to Chicago in the game, because after Longwell's field goal, the Bears took over with DB Ricky Manning, Jr. returning an interception 54 yards for a touchdown, while RB Cedric Benson got a 24-yard TD run. By the time the fourth quarter came around, QB Brad Johnson was benched for the game, due to throwing four interceptions. Back-Up QB Brooks Bollinger took over, but he fare any better, as he got sacked in his own end zone by NT Tank Johnson for a safety. Afterwards, the Vikings would have their only successful drive of the game with RB Ciatrick Fason getting a 4-yard TD run. Afterwards, Bollinger would get his left arm sprained during a sack, so rookie QB Tarvaris Jackson came in to finish the game. With the loss, Minnesota fell to 5-7.
Question: How many field goals did Longwell kick in the first half?
