Answer:
look for ways to reduce our dependence on oil
Explanation:
Look for ways to reduce our dependence on oil would be the best option. The United States is currently self sufficient in oil, and does not depend on the OPEC anymore. However, the OPEC can still represent a geopolitical adversary or threat, and for this reason, energy self-sufficiency should be used to look for ways to phase out oil for other energy sources, like nuclear, geothermal, or solar.
In the United States, the three main factors that make up the system of checks and balances would be the Executive Branch, the Legislative Branch, and the Judicial Branch, since the goal is to separate these powers so that no single power becomes too powerful.
If by South Africa you are referring to the Republic of South Africa, then their transition to Democracy was a bit rocky. It was a part of the British empire before they gained their independence as a free republic. This free republic however was not a democratic one due to things like apartheid rules where a minority of rich people who were mostly white controlled the government at the expense of the local African majority. As the fight for democracy continued many things started coming up like huge unemployment and infringement of human rights. Apartheid ended and currently the country is a democracy with suffrage, but there is evidence of high corruption among the government employees and the administration. Expand those ideas into an entire essay.
