Answer 2

Known as a 'Full Daley', after Daley Thompson, the first man to do it in 1983. The female equivalent is a 'Full Gunnell' after Sally Gunnell (who also held Goodwill Gams and world cup titles at the same time). Winning all the titles in the same event, but not simultaneously is a 'Career Daley' or 'Career Gunnell'
