The term 'Certain Olympian' can refer to three different athletes: a DIVER, an EPEEIST, and a bobsledder. A DIVER is an athlete who competes in the sport of diving, which involves performing acrobatic maneuvers while jumping or falling into water from a platform or springboard. An EPEEIST is a fencer who specializes in the epee, a type of fencing sword. Finally, a bobsledder is an athlete who competes in the sport of bobsleigh, which involves racing down an icy track in a two- or four-person sled. All three of these athletes compete in the Olympic Games.
