Answer:</h3><h2><em>
BRAZIL:</em></h2><h3><em>
Following more than three centuries under Portuguese rule, Brazil gained its independence in 1822, maintaining a monarchical system of government until the abolition of slavery in 1888 and the subsequent proclamation of a republic by the military in 1889. Brazilian coffee exporters politically dominated the country until populist leader Getulio VARGAS rose to power in 1930. By far the largest and most populous country in South America, Brazil underwent more than a half century of populist and military government until 1985, when the military regime peacefully ceded power to civilian rulers. Brazil continues to pursue industrial and agricultural growth and development of its interior. Having successfully weathered a period of global financial difficulty in the late 20th century, Brazil was seen as one of the world's strongest emerging markets and a contributor to global growth. The awarding of the 2014 FIFA World Cup and 2016 Summer Olympic Games, the first ever to be held in South America, was seen as symbolic of the country's rise. However, from about 2013 to 2016, Brazil was plagued by a sagging economy, high unemployment, and high inflation, only emerging from recession in 2017. Former President Dilma ROUSSEFF (2011-2016) was removed from office in 2016 by Congress for having committed impeachable acts against Brazil's budgetary laws, and her vice president, Michel TEMER, served the remainder of her second term. In October 2018, Jair BOLSONARO won the presidency with 55 percent of the vote and assumed office on 1 January 2019.</em></h3><h3 /><h2><em>
ARGENTINA: </em></h2><h3><em>
In 1816, the United Provinces of the Rio Plata declared their independence from Spain. After Bolivia, Paraguay, and Uruguay went their separate ways, the area that remained became Argentina. The country's population and culture were heavily shaped by immigrants from throughout Europe, with Italy and Spain providing the largest percentage of newcomers from 1860 to 1930. Up until about the mid-20th century, much of Argentina's history was dominated by periods of internal political unrest and conflict between civilian and military factions.</em></h3><h3 /><h3><em>
After World War II, an era of Peronist populism and direct and indirect military interference in subsequent governments was followed by a military junta that took power in 1976. Democracy returned in 1983 after a failed bid to seize the Falkland Islands (Islas Malvinas) by force, and has persisted despite numerous challenges, the most formidable of which was a severe economic crisis in 2001-02 that led to violent public protests and the successive resignations of several presidents. The years 2003-15 saw Peronist rule by Nestor and Cristina FERNANDEZ de KIRCHNER, whose policies isolated Argentina and caused economic stagnation. With the election of Mauricio MACRI in November 2015, Argentina began a period of reform and international reintegration.</em></h3>
