I would like to learn about London. 
 Sure! London is the capital and largest city of England and the United Kingdom. The River Thames runs through the city. London is the biggest city in western Europe, and the world's largest financial centre. 
 Wow, I didn't know London had the world's biggest finance centre. 
 Would you like to know more about London's economy? 
 Sure, that'd be great. 
 London is one of the world's most important cities for business, finance, and politics. It is also the world's biggest currency trading centre. It accounts for some 37% of the $5.1 trillion average daily volume. 
 Interesting. How are the sports there? 
 The Wimbledon Tennis Championships is one of London's best known annual sports competitions. It is held at the All England Club in the south western suburb of Wimbledon. 
 Any other sports competitions in London? 
 Rugby is also a popular sport in England. Though it is more popular in north England, there are two professional league clubs in London, The London Broncos in the top tier Super League, and the third tier team League 1 team, the London Skolars.
