1. What is a presidential system?
A government where the president is elected independently of the legislature and holds significant executive powers, with a separation of powers.
Explication
A presidential system is characterized by an independently elected president who serves as both head of state and head of government, with a clear separation of powers between the executive, legislative, and judicial branches. This setup ensures that the president is not dependent on the legislature for their appointment or confidence, unlike parliamentary systems. The other options describe features of parliamentary or hybrid systems, not a presidential system.
