1. Answer = The Magna Carta (which is Latin for Great Paper, or Great Charter) was so important because it effectively forced the reigning monarch to grant his English subjects rights. It laid the foundations for Parliament and constitutional governments.
2. Answer = Social contract theory, nearly as old as philosophy itself, is the view that persons' moral and/or political obligations are dependent upon a contract or agreement among them to form the society in which they live.
3. Answer = The difference between a democracy and a dictatorship is that in a democracy you vote first and take orders later; in a dictatorship you don't have to waste your time voting. 
4. Answer = The major difference between these two systems is that in a Presidential system, the executive leader, the President, is directly voted upon by the people (Or via a body elected specifically for the purpose of electing the president, and no other purpose), and the executive leader of the Parliamentary system.
5. Answer = The United States is a sovereign nation. Sovereignty is a simple idea: the United States is an independent nation, governed by the American people, that controls its own affairs. The American people adopted the Constitution and created the government. They elect their representatives and make their own laws.

Hope this helps!
