1. The problem asks to identify the type of government described: citizens vote every two years for representatives to make laws and every four years for a leader. 2. Recall the definitions: - A direct democracy has no single leader; decisions are made by majority vote of all citizens. - A representative democracy elects representatives to make decisions. - A limited monarchy has a monarch with limited power and representatives governing. - A presidential system elects representatives and a president as leader. 3. The description matches a system where representatives are elected to make laws and a leader is separately elected every four years. 4. This matches the definition of a presidential system. 5. Therefore, the government described is a presidential system. Final answer: **a presidential system**
