Hi can you tell me something about Cambodia? 
 You bet! The "Kingdom of Cambodia" is the official English name of the country. 
 Thanks. Can you tell me about the history of Cambodia? 
 The first mention of Cambodia in European documents was in 1511 by the Portuguese. 
 I didn't know that! Do you have any more information about the history? 
 In November 1978, Vietnamese troops invaded Cambodia in response to border raids by the Khmer Rouge. 
 Interesting. Lets switch topics. Can you tell me about the science and technology of Cambodia? 
 I'm sorry, I don't have that information at this time. 
 What other interesting facts do you have about Cambodia? 
 English is mostly used in Cambodia's international relationships and has replaced French in Cambodia's stamps and currency since 2002. 
 Do you have anything on science and technology yet? If not, can you tell me one more fun fact about Cambodia? 
 I'm sorry, I still don't have any information on science and technology. But did you know? Soccer was brought to Cambodia by the French and became popular with the locals. 
 Great - thanks for the info 
 Your welcome.
Cambodia
