Task: Question Answering
Input (English): passage: There is a great deal of debate as to where the boundaries lie between fact and fiction in the book. Roberts has stated the characters in the story are largely invented, and that he merged different elements taken from true events and people into such events and characters like Prabaker 'of the big smile'. Prabhakar Kisan Khare was a real-life individual, as are the members of Khare family from the book (Kisan, Rukhma, Kishor and Parvati Khare) whose names appear on government issued identity cards. The family resides in the Navy Nagar slum where the lead character Shantaram also lived. The Khare family disputes many of Roberts' claims, although they acknowledge close association with Gregory Roberts in the 1980s. Prabhakar died in an accident in 1988 in circumstances matching the event in the book. In March 2006, the Mumbai Mirror reported they may have discovered the inspiration for the big smile of the character Prabhakar as belonging to a still living cab driver called Kishore, who took Roberts to his home village. Kishore Khare, brother of Prabhakar, who drives tourists around Mumbai, has told his story.
 question: is the book shantaram based on a true story?
Output (English): Yes
