Our Geo quiz today was about mandatory voting laws around the world.
For the answer we consulted The International Institute for Democracy and Electoral Assistance based in Stockholm, Sweden.
The institute monitors elections worldwide.
It's no small job --- it estimates that there have been nearly 2,000 national elections since 1945.
The institute also says Belgium was the first country to enact a compulsory voting law way back in 1892.
Argentina did the same in 1914, and Australia made voting mandatory in 1924.
So Belgium, Argentina and Australia are the answers to today's Geo Quiz.
