1- The Soviet forces constructed
the Berlin Wall to prevent the
escape of East Germans into
West Germany.
2- US president Ronald Reagan
delivered a famous speech
challenging Soviet leader
Mikhail Gorbachev to tear
down the Berlin Wall.
3- Newly independent Hungary
opened its border with Austria.
4- East German leaders gave
orders to open the gates
of the Berlin Wall.
5- The representatives of East
and West Germany signed
the Reunification Treaty.
That is the PLATO answer
To keep up with the demands of industrialization
When a hole in the ground is formed by chemical waste.
The colonists could get property and move up the social scale.
Hope this helped!
