Peoples, culture, Coutry, sports.
I would like to know what you think of the people, culture, country, and sports.
This is a more complete way to explain what you want to know. In English, you can't start a sentence with a list. Good job using commas in the right places.
I don't know a lot about Brazil, but I think the language is interesting, and I think the cultural mix is really interesting to hear about. One of my students was from Brazil, and we talked about her country a little bit.
