Human society as a large system includes three systems: economy, politics, and culture. The economic system provides material benefits to society and optimizes the allocation of resources. The political system provides society with legal system, order, and justice. The cultural system provides social production and communication. Knowledge provides spiritual motivation and moral cohesion. The three are intertwined and indispensable. What can be inferred from this passage? ['Economic system cannot operate without cultural system.', 'Political and economic systems are irrelevant.', 'Cultural systems can also provide material benefits to society.', 'Economic systems can be dominated by political and cultural systems.']
