Q. On which of the following the economy of Brazil is mostly dependent?
Answer: Coffee
Notes: Coffee production in Brazil is responsible for about a third of all coffee, making Brazil by far the world's largest producer. It is a position the country has held for the last 150 years. Coffee plantations, covering some 27,000 km² are mainly located in the southeastern states of Minas Gerais, Sao Paulo and Parana where the environment and climate provide ideal growing conditions. So coffee is the main reason of Brazil’s economy.
