I seem to remember one of these type puzzles from a while back.
Boxing is one of the answers.
Annette (a net) is the girl that holds the cards up with "Round 1/2/3" on. I suggest you go and give the guy who set you the question a good thump.
The question was "Which 10 olympic sports use a net?"
Answer is:
Badminton, basketball, tennis, table tennis, volleyball, football, hockey, netball, waterpolo and boxing (then the awful line about Annette holding the numbers up...) (Ice hockey is a Winter Olympic sports)
