Answer:
False
Explanation:
Only one of the two are true. Works in the public domain have a copyright that has expired only. E.g. Works of classical music artist, are almost always expired, in accorance with American Copyright law. Abandoning a copyright doesn't do anything because so long the copyright has remained unexpired, the copyright remains. Thats why it can take decades for a new movie in a series to release, like "IT" by Stephen King. The copyright hasn't expired but rather was 'abandoned'. Before "IT" 2017 was relasesed, the copyright was abandoned.
