Prehistoric people (version larousse)

How does prehistoric people kill some enormous mammoths?

Well they didn't want to hurt themselves so they made traps to not hurt themselves. First they dig a hole then they covered the hole with branches and leaves. After that they wait for a mammoth to fall in their trap and when a mammoth fall in their trap they would all take stones and branches to throw on the mammoth until the mammoth die.
