Step 1 : Introduction to the question "In which sport is "Greco-Roman" a style?"
Greco-Roman wrestling is a style of wrestling that is practiced worldwide. It was contested at the first modern Olympic Games in 1896 and has been included in every edition of the summer Olympics held since 1908. This style of wrestling forbids holds below the waist; this is the major difference from freestyle wrestling, the other form of wrestling at the Olympics. Many believe that Greco-Roman Wrestling is the oldest sport on the planet, with ancient cave drawings suggesting that competitions may have been held way back in 3000 BC.
