Question

what happened when hungary opened its borders? west germans began to move to hungary. hungarians fled for east and west germany. germans fought over hungarian territory. thousands of people left east germany.

Explanation:

In 1989, Hungary opened its border with Austria, which allowed East German citizens (who had traveled to Hungary as tourists) to escape to West Germany via Austria. This was a key event leading to the fall of the Berlin Wall. The other options are incorrect: West Germans did not move to Hungary in this context, Hungarians did not flee to Germany in this scenario, and there was no fighting over Hungarian territory.

Answer:

Thousands of people left East Germany.
