The first topic is: What are some interesting rules of etiquette in your country? 여러분 나라의 흥미로운(재미있는) 매너(예절 또는 에티켓)는 어떤 것들이 있나요? Etiquette could be 에티켓, 매너 or 예절. It seems google is not that bad for this. Have you ever done any volunteer work? 여러분은 자원봉사활동을 해보신 적이 있나요? Volunteer work is 자원 봉사 활동. Yes, you can say that 자봉 as the abbreviation. How competitive are you? 여러분은 얼마나 경쟁력이 있나요? competitive is 경쟁력있는 아니면 경쟁의. Yes, it is. It seems google is quite correct in case of the words. I hope it is helpful for you. Cheers.
