Question

what was the most important effect of opening east germany’s borders? east and west germany merged into one nation. people traveled freely between east and west germany. germany’s political differences finally were resolved. thousands of west germans moved to east germany.

Explanation:

To determine the most important effect of opening East Germany’s borders, we analyze each option:

• Option "East and West Germany merged into one nation": The opening of borders was a key step that led to the eventual reunification (merging) of East and West Germany. This was a long - term and very significant outcome.
• Option "People traveled freely between East and West Germany": While this was an immediate effect of opening the borders, the long - term and more far - reaching effect was the reunification of the two Germanys.
• Option "Germany’s political differences finally were resolved": The opening of borders was part of the process, but the main tangible and major effect was the reunification, not just the resolution of political differences in an abstract sense.
• Option "Thousands of West Germans moved to East Germany": In reality, the movement was more from East to West, and this was not the most important effect. The reunification of the two countries was a much more significant outcome.

Answer:

A. East and West Germany merged into one nation.
