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.
If you haven't already got it set up in SQL server, restore the Historical Events database from the above folder.
Create a query to show the name of each event, together with the length of its description, sorted so that the longest description appears first:
Why there was most to say about the founding of the UN, owl only knows
Save this query as Showing length of description, then close it down.
