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.

Write as many of the following queries as your mean trainer gives you time for:

Query to show Returns
Events which aren't in the Transport category (number 14), but which nevertheless include the word Train in the EventDetails column. 4 rows
Events which are in the Space country (number 13), but which don't mention Space in either the event name or the event details columns. 6 rows
Events which are in categories 5 or 6 (War/conflict and Death/disaster), but which don't mention either War or Death in the EventDetails column. 91 rows

Save this query listing possible anomalies as Primeval, then close it down.
