Trying to snap a two-game skid, the Bears flew to the Hubert H. Humphrey Metrodome for a Week 15 Monday night NFC North rematch with the Minnesota Vikings. In the first quarter, Chicago struck first as kicker Robbie Gould got a 29-yard field goal for the only score of the period. In the second quarter, the Vikings tied the game with kicker Ryan Longwell getting a 42-yard field goal. Afterwards, the Bears would take the halftime lead as Gould kicked a 47-yard field goal and FB Jason McKie managed to get a 1-yard TD run. In the third quarter, Minnesota started to creep closer as RB Adrian Peterson got a 1-yard TD run (with a failed PAT) for the only score of the period. In the fourth quarter, the Vikings took the lead with Peterson getting an 8-yard TD run. Chicago tried to rally, but Minnesota's defense was too much. With their third-straight loss, not only did the Bears fall to 5-9, but they were knocked out of playoff contention. On a positive note, LB Brian Urlacher had a good day with 4 tackles, 2 sacks, and an interception. It was also the first time since 2004 that Urlacher had a sack and an interception in the same game.
Question: How many more field goals did Gould make than Longwell in the first half?
Answer: 1
