Answer:
There aren't any items to classify.
Step-by-step explanation:
Public domain refers to the state of belonging or being available to the public as a whole, so there is not copyright. Some examples include classical music works, artwork such as the Mona Lisa, literature works like the ones written by Shakespeare, Poe and some others.
Copyright is a mean of protecting an author's work; this type of intellectual property provides exclusive publication, distribution and usage rights for the author. Some examples are poems, books, plays, films and artwork.
