Instructions Competition Mode: For each correct answer, you get points based on how many other players get the question wrong. Your score is the sum of all correct answers.

Example: If you get a question correct that only 10% of all players get correct, you get 90 points for that question.

You can choose 5 questions to "Double". If you get it correct, your score is doubled for that question.

TIP: Easy questions aren't usually worth doubling since you are likely doubling a small number of points. You're better off doubling the hardest questions that you think you have correct (80 points possibly doubled is a lot better than 10 points definitely doubled).

You will not lose points for incorrect answers, so feel free to guess.

You can enter up to three group names, separated by commas, in the "Private Group" input. After you submit, when you view your results you can see the leaderboards for just your group(s). You will also get links you can share with others so they can play in those groups.
Feel free to create your own group name, such as your company or town, and pass the links along to friends, family, and coworkers.

Good luck!     
 
Question #5: Geography: What city is estimated to have passed Beijing, becoming the world's most populous urban area, in the mid-1820s, and held the title until passed by New York City 100 years later? It had an estimated population of 6.5 million at the turn of the 20th Century.

Answer: London
According to Tertius Chandler's 1987 work "Four Thousand Years of Urban Growth: An Historical Census", London grew nearly five-fold in the 100 years it held the title. Based on urban areas, New York, which was the first urban area with a population of 10 million, held the title until passed by Tokyo in the late 1950s or early 1960s. In 2020, Tokyo's urban area is approaching 40 million.
