Thomson Reuters is a big company that shares lots of information with other people. It's like when you share toys with your friends, but instead of toys they share news articles, stock prices, and other important information with people around the world.
Thomson Reuters makes sure that the information is accurate and up-to-date, so that people who use the information can make good decisions. This is kind of like when your mom makes sure that your shoes fit properly before you go outside to play, so that you don't trip and fall.
Thomson Reuters also has different parts to their company, like one part that works with businesses and another part that works with people who work in science and medicine. So it's kind of like how you have different toys in your toy box, but you play with some toys with your friends and other toys by yourself.
Overall, Thomson Reuters is like a really big helper that shares important information with people who need to know it, and makes sure that the information is correct and helpful.
