original_response: If you practice the different styles of swim you can partake in either freestyle or a medley relay.
history: I just signed up for swimming lessons!  I've always wanted to learn how to swim! Awesome. A lot of countries require the children to have a minimun level of swimming by the ending of their primary education Interesting!  Do you know some swimming techniques, like the back stroke? I don't have much information about those. But I know that kids can develop confidence through swimming lessons I had no Idea. What else do you know? Well, I also know that kids are viewed as not able to swim alone until 4 years old I see. So babies can't swim? What I know is that babies can't hold their heads above the water or hold their breath on purpose Good to know. I would love to participate in a relay
knowledge: In addition to these individual events, four swimmers can take part in either a freestyle or medley relay.
