The name of which chemical element derives from the Greek word for 'lazy'? And to which province of Canada does Cape Breton Island belong?

Russell Davies puts these and a plethora of other general knowledge questions to today's competitors, who come from Cardiff, Ayrshire, Northumberland and North Yorkshire. They're hoping to win a place in the 2014 semi-finals which begin in a few weeks' time.

Russell's questions cover history, music, science, literature, mythology, popular culture and more besides. There's also a chance for an ingenious listener to 'Beat the Brains' with questions of his or her own devising - with a prize on offer if the contestants' combined brainpower can't work them out.
