The best answer is, A. The United States' interests in Latin America have often led to intervention.
For decades the United States has pursued a foreign policy agenda of democracy building, this is especially present in developing countries such as those in Latin America, Africa, and the Middle East. When the United States has been unsuccessful in influencing the political structure to its benefit through diplomatic means it often turns to military and revolutionary means. The headlines reinforce this foreign policy agenda which has played out in many Latin American countries.
The steps that countries must take to transition to a mixed-market economy are: they must establish a fair labor market, and they must open up trade to other countries.
A mixed economy is an economic system which mixes elements of market economies with elements of planned economies. It's a mixture of public and private enterprise.
So, to have a country with a mixed-market economy, countries must establish fair labor market to have adequate conditions for the labor market. Moreover, they must open up trade to other international countries. That is to say, to have free trade which doesn't restrict exports or imports.
