Task: Question Answering
Input (English): Passage: Coming off their home win over the Buccaneers, the Eagles flew to the Oakland-Alameda County Coliseum for a Week 6 interconference duel with the Oakland Raiders. In the first quarter, both defenses played well, with the Eagles getting on the board first with a 45-yard field goal from kicker David Akers. However, the Raiders responded as QB JaMarcus Russell hooked up with TE Zach Miller on an 86-yard touchdown pass. In the second quarter, Oakland kicker Sebastian Janikowski hit a 29-yard field goal and Akers would hit a 43 yarder. Philadelphia got the ball back before the half but sputtered as they got close to the Oakland end zone and the half ended with the Raiders up 10-6. In the third quarter, the defenses battled back and forth and neither team scored. The final quarter's first points were scored by Oakland as Janikowski hit on a 46-yard field goal. David Akers scored on a 45-yard field goal for the Eagles, but when they got the ball back late in the fourth quarter, they turned it over on downs and the Raiders ran the clock out. 
Question: How many yards was the shortest field goal of the first half?
