Hello. Please educate me about Africa. 
 That's sad. Please tell me more about it. 
 Where did Africa got its name? 
 I see. What information do you have about their economy? 
 The only fact, while not extremely informative, I can give you about etymology is that. as Europeans came to understand the real extent of the continent, the idea of "Africa" expanded with their knowledge.
