Hello: I would like to learn about Berlin> 
 Certainly! Berlin is the capital city of Germany located along its east side, with a population of over 3,700,000. What specifically would you like to know? 
 I would like to learn about the government of Berlin, please. 
 The government of Germany was in Berlin for many years. Berlin's executive body is the Senate of Berlin. The governing Mayor of the city is Michael Muller 
 Sounds very much like our system of government. Do you have any additional information on Berlin's government. 
 Yes! Interestingly enough, the Mayor also serves simultaneously as Lord Mayor of the city of Berlin, and Minister President of the Federal State of Berlin. 
 The Mayor is the Mayor and Lord Mayor? Any info on the difference betwwen the two? 
 The Mayor is also, the Lord Mayor AND Minister President. And, I'm sorry, but I don't have information differentiating the two. Would you like to hear more about their government? 
 If you have additional information on the government of Berlin, that'd be great. 
 There has been a coalition between the Greens, the Left Party, and the Social Democratic Party, since the 2016 state elections. 
 Thank you again, switching topics, do you have any information on the culture of Berlin? 
 Berlin is home to three major Opera Houses. They are also well known for the cultural festival jazz festival, Berliner Festspiele. 
 Nice, I want to thank you for all of the good information. 
 You're welcome.
