An exemplified copy is like a special type of copy that is made official by the government. Let's say you have an important document, like a birth certificate or a marriage certificate. You might need to show this document to someone, like your school or your job, but they need to make sure it's the real deal. So, you can go to a government office and ask for an exemplified copy.
They will make a copy of your document, but it's not just any old copy. They will put a special stamp or seal on it, and sign it to show that it's real. This makes it official and proves that the information on the document is true. It's like a fancy way to show off your important papers to other people, with the government's approval.
