Answer:
The two predominant forms of democratic governments in Eastern Asia are parliamentary and presidential systems. In a parliamentary system, the head of government is typically the leader of the largest party or coalition of parties in the parliament. The parliament is responsible for selecting and appointing the executive branch of government, including the Prime Minister or equivalent position. In contrast, a presidential system features a separation of powers between the executive and legislative branches of government. The President is elected separately from the parliament and is not a member of the legislature. They serve as both the head of state and the head of government. Additionally, presidential systems often have a more rigid separation of powers between the branches, while parliamentary systems tend to have more overlap and interaction between them. Overall, the differences between the two systems lie in the balance of power and relationships between the executive and legislative branches of government.
