I would go with letter b. Armenia/Republic
of Georgia.<span> Prior to
the First World War, its name was Armenia.
When the war ended it was known as the Republic of Armenia. The choices were correct in the pre and post
war names.</span>
Choose B: a book written by a historian who is an expert on medieval Europe.
I trust that book because the book was written by an EXPERT. Someone who is trustworthy and knows more about a student-produced website.
