I'm sorry, but I still do not have that information. 
 Do you have any information regarding their educational system? 
 I'm sorry, I don't have that information at the moment. Would you like to know a fact about the economy? 
 Yes. After the Berlin Wall was built in 1961, very few people were allowed to cross from East into West Berlin. The Berlin Wall divided the city until 1989, when the East German government decided to allow anybody to cross, resulting in people deciding to destroy the wall. 
 I didn't know that. What can you tell me about Berlin's education?
Yes. After the Berlin Wall was built in 1961, very few people were allowed to cross from East into West Berlin. The Berlin Wall divided the city until 1989, when the East German government decided to allow anybody to cross, resulting in people deciding to destroy the wall.
