Onuneven development of East and West Germany during the Cold War.
O All of the choices are correct.
O the release of the Stasi files.

All of the choices are correct.

Explanation:

All of the choices are correct.

The German reunification was a complicated process, and its consequences can be felt to this day.

The former German Democratic Republic (East Germany) was much poorer than Western Germany, so much that even today, the German regions that belonged to East Germany are still poorer than their western counterparts.

Higher unemployment in East Germany was obviously a consequence of this economic disparity.

The release of the Stasi files was also controversial, and many people disagreed with it. The Stasi files revealed that the former German Democratic Republic had spied on its citizens in order to keep societal control.
