Explanation:

Features of Presidential Systems: ? Single Executive: In a presidential system of Government, one of the features is the existence of a single executive which means that the executive arm of the government is headed by a single person who is the head of state and the head of the government which means he performs both the ceremonial functions and the governmental functions, he is known as the president. (Hence statement 1 is correct) ? Fixed Term of Office: In a presidential system of government, the president is elected for a particular term of office, which differs in countries as each country has a different constitution; it is usually four years but it could also be five or seven in other countries. The president is therefore elected for a constitutionally accepted fixed term in office. ? Executive accountability: The president is always directly elected by the people (citizens), hence the president drives his mandate from the people, and he is accountable to them directly for his actions and in-actions in office. ? Recognized Opposition: Another feature of the presidential system of government is that the role of the opposition is clear; it is expressly stated by the constitution. Party discipline is, therefore, not very strong. ? Supremacy of the Constitution: In a presidential system of government, the constitution is the supreme law of the land. Anyone who exercises his powers outside the constitutional mandate is deemed to be in contravention of the constitution. Such actions would be nullified by the judiciary. ? Executive Branch of the Government is Unipersonal: The members of the presidential candidate serve at the command of the president and must carry out the rules of the executive and legislative branches. In the presidential system of government, the president often needs the approval of the legislature of the executive nominations of the cabinet, judiciary, and various lower governmental posts. A president can generally direct the military, members of the cabinet, or any officer or employee of the executive branch, but cannot dismiss the judges or direct them. ? Checks and Balances: Another feature of the presidential system of government is the principle of checks and balances. An example of checks and balances is the right to veto power. The veto power was derived traditionally from the British tradition of royal assent, in which the parliament could only be enacted with the assent of the monarch. The president (executives) could veto legislatives acts and actions, and in return, a great majority of the legislative arm of government could override the veto. ? Presidential Pardon: A feature of a presidential system of government is presidential pardon. A president can grant pardon to a convict who has a life sentence, death sentence or a long sentence and this is solely at his own discretion. ? Separation of powers: The principle of separation of power solely vests in the presidential system of government as powers are shared between the Executives, Legislatures, and the Judiciary. These arms of government a separate from each other but they see to the smooth running of the government. (Hence statement 2 is correct) ? Power of Appointment and Execution: Another feature of the presidential system of government is that the president has the power to appoint Supreme Court judges, (the highest members of the judiciary). ? Stable government: This type of Government is stable. Since the term of the President is fixed and not subject to majority support in the Legislative, he need not worry about losing the government. There is no danger of a sudden fall of the government. There is no political pressure on the president to take decisions. (Hence statement 3 is Incorrect)
