Context: Coming off huge home wins against the 49ers and Steelers, the Seahawks traveled to Minneapolis to take on the Minnesota Vikings. Despite being without both Marshawn Lynch and Jimmy Graham, the Seahawks dominated the Vikings 38-7. Going into the game, the Vikings were previously 8-3 and leading the NFC North, led the NFL in team rushing yards, and Adrian Peterson was the NFL's leading rusher. The Seahawks defense held Peterson to only 18 yards and the Vikings' offense failed to score (their only points coming on a special-teams kickoff return), while Russell Wilson and the Seattle offense racked up 433 yards, five total touchdowns, and no interceptions.

Question: How did the Vikings' score?

Answer:
a special-teams kickoff return
