Based on the app's description, I've identified three topics that players of sports quizzes might discuss online. Here are the topics with three questions each, each with exactly 20 words: **Topic 1: Favorite Sports** What is the most popular sport in the US? Which European country has the most successful soccer teams? Who is the most dominant athlete in tennis, past or present? **Topic 2: Quirky Sports Trivia** What is the only Olympic sport where the competitor keeps their rifle in the playing area? In which sport do athletes compete to be the fastest while sitting down? Which sport has the most countries participating in the Olympics? **Topic 3: Unconventional Sports** What is the smallest sport played at the Olympics, in terms of participant numbers? In which sport do athletes wear full-body animal costumes to compete? What sport is also known as "gutknot")
