Step-by-step explanation:
Based on the description provided, the economic system in the lost city of Atlantis is characterized by "Free markets" and "Pure capitalism." In a system with free markets, the factors of production are privately owned, and economic activity is primarily driven by market forces of supply and demand. The absence of government intervention or coordination of prices indicates a lack of central planning or socialism. Additionally, the mention of privately owned factors of production aligns with the principles of capitalism, where private individuals or entities own and control the means of production.
