One category. Four countries. Pick the world leader.
How to play & scoring
Choose the country with the highest value — the one with the best global rank.
Worked example
If the four options have values 12, 80, 45 and 31 in the same unit and year, the option with 80 wins. It need only lead these four choices, not every country in the world.
Examples illustrate the rules. They are not real country statistics or answers to your round.
What to watch for
Read whether the category measures a total, a percentage or a value per person. Population size may help with a total, but does not by itself tell you which country leads a rate or share.
