      "question": "How did the police respond to the 2011 Norway attacks?",
      "answer": "The police response faced significant delays, including challenges with boat transport to reach the island of Utøya, which resulted in the 22. juli-kommisjonen identifying critical failures in emergency readiness and communication."

      "question": "Was the perpetrator of the 2011 Norway attacks acting alone?",

      "answer": "The 22. juli-kommisjonen report concluded that security measures were inadequate, specifically citing that the government quarter in Oslo should have been closed to traffic and that the perpetrator could have been stopped earlier if existing intelligence had been acted upon."
