Explanation:
1- Civil rights are those that protect individual liberties from their illegal breakdown (repression) by the power (be it that of governments or any other public or private political agent), and guarantee the citizen's ability to participate in politics in conditions of equality, without discrimination.
2- The Cold War was a political, economic, social, military, informative and scientific confrontation initiated after the end of World War II between the Western bloc led by the United States, and the Eastern bloc led by the Soviet Union. Neither of the two blocks ever took direct actions against the other, which is why the conflict was called "cold war".
3- Containment was a policy adopted by the United States towards the Soviet Union during the early years of the Cold War. The purpose of this policy was to defeat the Soviet Union by preventing the expansion of the territory under the control of communist regimes.
4- Cosmonaut is the name given to space travelers from the Soviet Union and, currently, Russia.
5- Draft generally indicates the registration, provided for by the law, of the citizens of a State in special lists, in order to allow the latter to call for compulsory military service with the armed forces.
6- Segregation consists in the separation of different groups from the majority. These groups are stripped of their rights and discriminated against, isolating them from the rest of society.
