Select all correct answers: the following items are examples of "artifacts":

1.an ancient native american spear found at a dig site

2.a leaf preserved in stone

3.the skull of the kennewick man

4.a piece of pottery found at the ozette dig site

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 :)

the group i'm selecting: greeks.

a first group of greek immigrants came to the us in the 1850s. the second group came to america starting in the 1890s due to economic opportunities they didn't have back in their home caused by the hardships of ottoman rule. greek immigration was 90% male, many of them expected to work and return to greece after earning enough capital, but ultimately had to remain in the us after the greek genocide.
