People who lived in eastern bloc countries after World War II could not:

a Participate in government.

b Travel on street cars.

c Send children to school.

People who lived in Eastern bloc countries after World War II could not participate in government. The correct answer is A. It was forbidden to them to take any part in the government, while it would be breaching basic human rights not to allow them to travel on street cars and send their children too school, so those answers are incorrect.
