The office of censorship is like when your mom or dad checks your TV shows, movies or books before you watch or read them, to make sure they are appropriate for you.
The office of censorship is a group of people who check books, movies, TV shows and other things to make sure that they are also appropriate for adults. This means they make sure that there is nothing bad like violence, bad language, sex or other things that adults shouldn't see or hear.
The office of censorship checks these things before they are allowed to be shown or sold to people so that everyone can enjoy them without being exposed to anything that might be harmful.
