Sovereignty refers to the right that confers the authority to rule over a certain territory.
The question refers to France, which has sovereignty to rule in their department in South America, know as the French Guiana, which is a region of France and therefore part of the European Union.

The GI Bill of Rights was passed in 1944, and it encouraged veterans to go back to school. It gave them money to go back to school if they wanted to. So, I would say that the answer would be C. It provided financial aid for veterans going to college. Hope this helps! :)
