Task: Question Answering
Input (English): passage: The Other Boleyn Girl (2001) is a historical novel written by British author Philippa Gregory, loosely based on the life of 16th-century aristocrat Mary Boleyn (the sister of Anne Boleyn) of whom little is known. Inspired by Mary's life story, Gregory depicts the annulment of one of the most significant royal marriages in English history (that of King Henry VIII and Catherine of Aragon) and conveys the urgency of the need for a male heir to the throne. Much of the history is highly distorted in her account.
