Task: Question Answering
Input (English): Context: The Amazon River (or ; Spanish and ) in South America is the largest river by discharge of water in the world, and according to some experts, the longest in length.
The headwaters of the Apurímac River on Nevado Mismi had been considered for nearly a century as the Amazons most distant source, until a 2014 study found it to be the Cordillera Rumi Cruz at the headwaters of the Mantaro River in Peru. The Mantaro and Apurímac confluence, and with other tributaries form the Ucayali River, which in turn confluences with the Marañón River upstream of Iquitos, Peru, to form what countries other than Brazil consider to be the main stem of the Amazon. Brazilians call this section the Solimões River above its confluence with the Rio Negro to form what Brazilians call the Amazon at the Meeting of Waters at Manaus, the river's largest city., The right of nations to self-determination (from ) is a cardinal principle in modern international law (commonly regarded as a "jus cogens" rule), binding, as such, on the United Nations as authoritative interpretation of the Charters norms. It states that nations, based on respect for the principle of equal rights and fair equality of opportunity, have the right to freely choose their sovereignty and international political status with no interference. This principle can be traced to the Atlantic Charter, signed on 14 August 1941, by Franklin D. Roosevelt, President of the United States of America, and Winston Churchill, Prime Minister of the United Kingdom, who pledged The Eight Principal points of the Charter. It also is derived from principles espoused by United States President Woodrow Wilson following World War I, after which some new nation states were formed, or previous states were revived after the dissolution of empires. The principle does not state how the decision is to be made, nor what the outcome should be, whether it be independence, federation, protection, some form of autonomy or full assimilation. Neither does it state what the delimitation between nations should benor what constitutes a nation. There are conflicting definitions and legal criteria for determining which groups may legitimately claim the right to self-determination., Colombia (or ), officially the Republic of Colombia, is a transcontinental country largely situated in the northwest of South America, with territories in Central America.

These are often described as stateless societies, although several authors have defined them more specifically as institutions based on non-hierarchical free associations.

While anti-statism is central, anarchism entails opposing authority or hierarchical organization in the conduct of all human relations, including, but not limited to, the state system., South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere. It is also considered a subcontinent of the Americas, which is the model used in nations that speak Romance languages. The reference to South America instead of other regions (like Latin America or the Southern Cone) has increased in the last decades due to changing geopolitical dynamics (in particular, the rise of Brazil)., Luis Miguel Sánchez Cerro (August 12, 1889, Piura  April 30, 1933, Lima) was a high-ranking Peruvian army officer and President of Peru from 1931 to 1933.

More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history. Over nine million combatants and seven million civilians died as a result of the war (including the victims of a number of genocides), a casualty rate exacerbated by the belligerents' technological and industrial sophistication, and the tactical stalemate caused by gruelling trench warfare. It was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved., Nationalism is a complex, multidimensional concept involving a shared communal identification with one's nation. It is a political ideology oriented towards gaining and maintaining self-governance, or full sovereignty, over a territory of historical significance to the group (such as its homeland). Nationalism therefore holds that a nation should govern itself, free from unwanted outside interference, and is linked to the concept of self-determination. Nationalism is further oriented towards developing and maintaining a national identity based on shared characteristics such as culture, language, religion, political goals and/or a belief in a common ancestry.

The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Argentina and Chile., Fascism is a form of radical authoritarian nationalism that came to prominence in early 20th-century Europe.

Opposed to liberalism, Marxism, and anarchism, fascism is usually placed on the far-right within the traditional leftright spectrum., Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America.
