Could you tell me about European Union 
 Located mostly in Europe, it's a political and economic union of member states. 
 Good. Can you tell me more about the Economy 
 Two of the objective there were to develop a customs union between its member states and developing a common market which eventually became a single market. 
 I am interested in knowing more about this place 
 The Maastricht Treaty was signed in 1992. The member states were legally bound to fulfill the agreed-on rules if they wanted to become part of the monetary union 
 I did'nt get that can you explain me in detail 
 The only information provided is that the treaty was a negotiation of the structure and procedures of a currency union. 
 Ok. I would like to know about the Demographics of this place 
 It consists of around 40 urban areas with over one million people. There are also two so-called megacities of London and Paris. These cities have over 10 million people each. 
 Interesting. I would like to know more about London and Paris 
 I'm sorry I do not have any additional information on London and Paris. Here is a fact on demographics. Back in 2009, there were an estimated over a million Jewish people and the Muslim population was around 13 million.
