Task: Question Answering
Input (English): Context: Coming off their Monday night road win over the Saints, the Vikings went home for a Week 6 NFC North duel with the Detroit Lions.

In the second quarter, Detroit got the lead as kicker Jason Hanson got a 40-yard field goal. In the third quarter, the Lions increased their lead as Orlovsky completed a 12-yard TD pass to WR Calvin Johnson. The Vikings answered with QB Gus Frerotte completing an 86-yard TD pass to WR Bernard Berrian.

The Vikes sealed the win with kicker Ryan Longwell nailing the game-winning 26-yard field goal.
