input: Make use of the article to answer the questions. Buenos Aires ( or ; ) 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 city of Buenos Aires is neither part of Buenos Aires Province nor the Province's capital; rather, it is an autonomous district. In 1880, after decades of political infighting, Buenos Aires was federalized and removed from Buenos Aires Province. The city limits were enlarged to include the towns of Belgrano and Flores; both are now neighborhoods of the city. The 1994 constitutional amendment granted the city autonomy, hence its formal name: Ciudad Autonoma de Buenos Aires (Autonomous City of Buenos Aires). Its citizens first elected a chief of government (i.e. mayor) in 1996; previously, the mayor was directly appointed by the President of the Republic. 1. What river is Buenos Aires near?
