I want to know the answer to the following question:
Of all the countries in South America, which provided the most legal immigrants in 2013?
All the background I'm provided with is that "Ecuador, Colombia, Guyana, Peru, and Brazil were the top source countries from South America for legal immigrants to the New York City region in 2013; the Dominican Republic, Jamaica, Haiti, and Trinidad and Tobago in the Caribbean; Egypt, Ghana, and Nigeria from Africa; and El Salvador, Honduras, and Guatemala in Central America.". Is that enough to answer the question?
