You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

Create a query using an outer join to list out those countries which have no corresponding events.

If you succeed, you should get a country which has no events despite having the world's fourth largest population.

Save this query as Another country, then close it down.
