This quiz was generated using OpenAI's GPT-4o large language model, leveraging the reported, edited and vetted stories that garnered the most views over the past week. AI autonomously creates each quiz question, including multiple answer choices and a detailed explanation for the correct answer. Following this, a newsroom journalist reviews and edits each element for accuracy, appropriateness and sensitivity, ensuring the content remains reflective of the original article from which it's generated.
