What is a period format of matches in Greco-Roman wrestling?
Correct answer: Two three-minute periods

Rusty,
I agree, I think there was a mistake in the answer (2 three minute rounds instead of 3 two minute rounds)
I got it right by eliminating what I think are impossibly long rounds ie. 30 minutes, 45 minutes and 60 minutes.
No wrestler could fight that length of time without a break.

How can you last 45 mins in each match? That's way impossible

Rusty
first you indicate 2 three minute periods, then you talk about 3 periods. Get your info together!

It would be really awkward if they would wrestle for 10 minutes and they would get tired so the 3 minutes makes sense.
