Final answer:
The Archaic Indians did travel across the Bering Strait during the last ice age, according to the Bering Land Bridge migration model.
Step-by-step explanation:
The statement that the Archaic Indians traveled across the Bering Strait is true. The Bering Land Bridge migration model suggests that during the last ice age, humans migrated from Siberia to Alaska by crossing the land bridge between the continents, which had been revealed by dropping sea levels. This migration occurred between approximately 50,000-10,000 BP, and several migrations took place during this time. Therefore, the Archaic Indians did indeed travel across the Bering Strait.
