Okay kiddo, there is a place called the Center for Research and Documentation on World Language Problems. This is a place where grown-ups go to learn and study about problems that people have with languages all over the world. A language is a way of communicating with other people by speaking, reading, and writing.
So, why do people have problems with languages? Well, sometimes people from different places speak different languages, and they might not understand each other. That's why we have translators and interpreters to help us communicate with people who speak another language.
The center helps people all over the world to understand more about different languages and how they can better help people who speak different languages communicate with each other. They also study how languages change over time, and how people use language in different ways.
So, in short, the Center for Research and Documentation on World Language Problems is a place where grown-ups study and learn about how to help people who have trouble communicating because of different languages, and how to make communication easier for everyone.
