Answer:
3. The mastodon lived after the Ice Age when the sea levels were high.
Explanation:
The "Manis Mastodon Site" is an area where bones and teeth of mastodon remains were found in Manis Farm, Washington. The evidence also gave a hint that the early humans were already using tools to hunt the mastodon. This proved that the the earliest inhabitants on earth lived 800 years earlier than that of the "Clovis people."
The Clovis people were believed to have lived after the Ice Age when the sea levels were low, for this allowed them to cross the Beringia land bridge from Siberia going to the Rocky Mountains. If the evidence showed that the mastodon lived before the Clovis people (around 15,000 years ago when the sea level rose), then it goes to show that the mastodon lived after the Ice Age when the sea levels were high. Thus, the remains proved that there were early inhabitants before the Clovis People.
So, this explains the answer.
