Visit Frau Richardson's homepage to take a virtual look 
at some of the places you read about in your brochure. 
For example, you read and answered questions about Schloss Charlottenburg, 
the Reichstag building, and the Brandenburg Gate.  You could choose to look
at pictures of any of those.  Or take a look at Checkpoint Charlie, Kreuzberg, or
Kurfürstendamm.  It's your choice!  There are no specific questions to answer; 
all you have to do is keep a list of the pictures you looked at.  
How many? That's up to you, too - but I'd suggest at least 4 or 5.
