Task: Question Understanding
Input (English): Passage: The Packers broke their three-game losing streak with a victory in Minnesota. Green Bay held Minnesota to two scores, including a 47-yard pass from Teddy Bridgewater to Kyle Rudolph for the game's first touchdown. The Vikings' extra point try went wide, and after three Green Bay field goals, the Packers closed out the first half with a TD pass from Rodgers to Cobb to take a 10-point lead. Adrian Peterson scored in the third quarter to bring the Vikings within six points of the Packers, but Green Bay got it back with a long pass from Rodgers to James Jones in the corner of the end zone. Two second-half Crosby field goals brought Green Bay's total to 30, and the Vikings relinquished their brief first-place standing in the NFC North back to the Pack.
Question: How many field goals were kicked in the first half?
