Suppose Game of Thrones is an American fantasy drama television series created by David Benioff and D. B. Weiss. 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".
Can we infer that "Game of Thrones is based on a series of fantasy novels written by George R. R. Martin"? Yes, no, or maybe?
