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.

1st query should not return 4 rows but 1

select * from tblEvent
where EventDetails like '% train %' and CategoryID != 14

i guess your query is:

EventDetails like '%train%'          

which is incorrect as it will return words such as training...etc
