Greetings! What can you tell me about Berlin and demographics? 
 Berlin is the capital city of Germany. It is also the biggest city in Germany with a population of 3,700,00.00. 
 Great! What more can you tell me about the population? 
 Berlin is the second most populous city proper in the EU. The Greater Berlin Act of 1920 incorporated many suburbs and surrounding cities of Berlin. 
 That's interesting information about the population. Is there more you can tell me about the Greater Berlin Act of 1920? 
 The Greater Berlin Act also included villages and estates to create large cities. 
 Ok that's interesting. I am really interested in information about the economy also, can you tell me anything about it? 
 The Science and Business Park in Adlershof is the largest technology park in Germany measured by revenue. 
 Huh, that makes me wonder... is there more you can tell me about the technology park in Adlershof? 
 Berlin is a world city of culture, politics, media and science. Generating a revenue of 15.6 billion Euro and 6% of all private economic sales the culture industry grew from 2009 o 2014 at average of 5.5% per year. 
 Wow, that's a lot of Euros! Is there anything more you can tell me?
