Answer the following question: Information: - Head of government is a generic term used for either the highest or second highest official in the executive branch of a sovereign state, a federated state, or a self-governing colony, (commonly referred to as countries, nations or nation-states) who often presides over a cabinet, a group of ministers or secretaries who lead executive departments. The term "head of government" is often differentiated from the term "head of state", (e.g. as in article 7 of the Vienna Convention on the Law of Treaties, article 1 of the Convention on the Prevention and Punishment of Crimes against Internationally Protected Persons, including Diplomatic Agents and the United Nations protocol list), as they may be separate positions, individuals, and/or roles depending on the country. - Buenos Aires ("Provincia de Buenos Aires"; English: "good airs") is the largest and most populous Argentinian province. It takes the name from the city of Buenos Aires, which used to be the provincial capital until it was federalized in 1880. The current capital of the province is the city of La Plata, founded in 1882. - Commuter rail, also called suburban rail, is a passenger rail transport service that primarily operates between a city centre, and the middle to outer suburbs beyond 15km (10 miles) and commuter towns or other locations that draw large numbers of commuterspeople who travel on a daily basis. Trains operate following a schedule, at speeds varying from 50 to 200km/h (30 to 125mph). Distance charges or zone pricing may be used. - Buenos Aires is the capital and most populous city of Argentina. The city is located on the western shore of the estuary of the Rio de la Plata, on the South American continent's southeastern coast. "Buenos aires" can be translated as "fair winds" or "good airs", but the first one was the meaning intended by the founders in the 16th century, by the use of the original name "Real de Nuestra Senora Santa Maria del Buen Ayre". The Greater Buenos Aires conurbation, which also includes several Buenos Aires Province districts, constitutes the fourth-most populous metropolitan area in the Americas, with a population of around 17 million. - The Mitre line is an Argentine broad gauge commuter rail service in Buenos Aires Province as part of Ferrocarril General Bartolome Mitre . The service is currently operated by State - owned company Operadora Ferroviaria Sociedad del Estado after the Government of Argentina rescinded contract with Corredores Ferroviarios in March 2015 . - The government of Argentina, within the framework of a federal system, is a presidential representative democratic republic. The President of Argentina is both head of state and head of government. Executive power is exercised by the President. Legislative power is vested in both the Executive and the National Congress. The Judiciary is independent from the Executive and from the Legislature. - A head of state (or chief of state) is the public persona that officially represents the national unity and legitimacy of a sovereign state. In developing the current Constitution of France (1958), former French president Charles de Gaulle said the head of state should embody "the spirit of the nation" (""). In some countries, typically those with parliamentary governments, the head of state is a ceremonial figurehead that does not actually guide day-to-day government activities and may not even be empowered to exercise any kind of political authority (e.g., Queen Elizabeth II in the United Kingdom). In other countries, the head of state is also the head of government, such as in the U.S., where the president is both a public figurehead and the actual highest ranking political leader who, in practice, oversees the executive branch. - The President of the Argentine Nation, usually known as the President of Argentina, is both head of state and head of government of Argentina. Under the national Constitution, the President is also the chief executive of the federal government and Commander-in-Chief of the armed forces. - Executive Power is Vince Flynn's fifth novel, and the fourth to feature Mitch Rapp, an American agent that works for the CIA as an operative for a covert counter terrorism unit called the "Orion Team." - La Plata is the capital city of the Province of Buenos Aires, Argentina, and of the partido La Plata. According to the , it has a population of 765,378 and its metropolitan area has 899,523 inhabitants. - The judiciary (also known as the judicial system or court system) is the system of courts that interprets and applies the law in the name of the state. The judiciary also provides a mechanism for the resolution of disputes. In some nations, under doctrines of separation of powers, the judiciary generally does not make law (which is the responsibility of the legislature) or enforce law (which is the responsibility of the executive), but rather interprets law and applies it to the facts of each case. In other nations, the judiciary can make law, known as Common Law, by setting precedent for other judges to follow, as opposed to Statutory Law made by the legislature. The Judiciary is often tasked with ensuring equal justice under law. - A republic (from ) is a sovereign state, country, or government which is organized with a form of government in which power resides in elected individuals representing the citizen body and government leaders exercise power according to the rule of law. In modern times, the definition of a republic commonly refers to a government which excludes a monarch. Currently, 147 of the world's 206 sovereign states use the word "republic" as part of their official names; not all of these are republics in the sense of having elected governments, nor do all nations with elected governments use the word "republic" in their names. - A suburb is a residential area or a mixed use area, either existing as part of a city or urban area or as a separate residential community within commuting distance of a city. In most English-speaking regions, suburban areas are defined in contrast to central or inner city areas, but in Australian English and South African English, "suburb" has become largely synonymous with what is called a "neighborhood" in other countries and the term extends to inner city areas. In some areas, such as Australia, China, New Zealand, the United Kingdom, and a few U.S. states, new suburbs are routinely annexed by adjacent cities. In others, such as Arabia, Canada, France, and much of the United States, many suburbs remain separate municipalities or are governed as part of a larger local government area such as a county.
