Task: Question Answering
Input (English): Passage: Hoping to rebound from their home loss to the Patriots, the Cowboys stayed at home for a Week 7 intraconference game against the Minnesota Vikings.  In the first quarter, Dallas scored first as QB Tony Romo completed a 5-yard TD pass to WR Terrell Owens.  The Vikings would respond with RB Adrian Peterson getting a 20-yard TD run.  In the second quarter, Minnesota took the lead after a turnover.  WR Patrick Crayton fumbled a pass, which was picked up LB Ben Leber, who later lateraled the ball to CB Cedric Griffin, who would eventually fumble and recover the ball at the Cowboys 28-yard line and run it into the end zone for a touchdown. In the third quarter, RB Marion Barber got a 1-yard TD run, while Safety Pat Watkins returned a blocked field goal by Chris Canty 68 yards for a touchdown.  It would mark the first time that a Cowboy player returned a blocked field goal since Ed "Too Tall" Jones in 1983 against the New Orleans Saints on Sept. 25, 1983.  In the fourth quarter, Dallas sealed the victory with rookie Nick Folk getting a 45-yard field goal. With the win, the Cowboys entered their bye week at 6-1.
