Answer:
Explanation:
The definition of artifact is an object made by a human being, typically an item of cultural or historical interest. Thus, an artifact must be made by a human being to be qualified to be an artifact. So, I believe the first: An ancient Native American spear found at a dig site and fourth: A piece of pottery found at the Ozette Dig site, are the best answers that fit the definition of artifact.
I hope this helps :)
