Final answer:
Brazil's government, which includes an elected president and legislative bodies, aligns with a presidential democracy, a form of government where the chief executive and legislature are elected separately with distinct powers.
Step-by-step explanation:
The government described in the student's question, where a president is elected by the citizens and where there is also an elected legislative body, is most commonly referred to as a presidential democracy. Brazil, like the United States, operates under this system. In a presidential democracy, the chief executive (the president) and the legislative branches are elected separately by the citizens, and while they work together to run the government, they operate with distinct powers. In Brazil, the president has the authority to veto laws passed by the legislative branch, and the legislature can overturn such a veto, generally requiring a supermajority. This form of governance is characterized by its checks and balances, separating the powers of the different branches of government to prevent any one part from becoming too powerful.
