Suppose 'Game of Thrones' is an American fantasy drama television series created by David Benioff and D. B. Weiss for HBO. It is an adaptation of A Song of Ice and Fire, George R. R. Martin's series of fantasy novels, the first of which is A Game of Thrones. The show was filmed in Belfast and elsewhere in Northern Ireland, Canada, Croatia, Iceland, Malta, Morocco, Scotland, Spain, and the United States.
Can we infer that "The show is based on a popular book series"? Yes, no, or maybe?
