Example Input: Question: Were the Oz books the only books L. Frank Baum ever wrote? Passage:The Land of Ev is a fictional country in the Oz books of L. Frank Baum and his successors. Its exact location is unclear between text and maps. The Road to Oz states that Ev is to the north of the Land of Oz, and in Ozma of Oz, Princess Ozma of Oz and her procession enter the Munchkin Country and meet the King of the Munchkins upon leaving the palace at Evna, the capital city. Subsequent books place Ev nearer to the Winkie Country, and the map on the endpapers of Tik-Tok of Oz shows the Munchkin Country as having no northern border with the desert that surrounds Oz, as a thin strip of the Gillikin Country extends even farther east than most of the Munchkin Country. This map depicts Ev as a small country to the northwest (the compass rose is reversed) of Oz, with the Dominions of the Nome King as a separate area. James E. Haff and Dick Martin's map, following the text, place the Nome Kingdom under an Ev that takes up the entire portion allotted to the Nome King's dominions on Baum's map.

Example Input: Question: How old was Kashmira Shah went she was confirmed as part of Bruce Lee -The Fighter's cast? Passage:Samantha was replaced by Rakul Preet Singh at the same time.

Vaitla considered Ramya Krishnan, Tulasi and Jeevitha from Telugu cinema and also searched for yesteryear heroines in Tamil and Kannada cinema for the role of Charan's mother which was very crucial for the film's story. Kriti Kharbanda made a comeback to Telugu cinema with this film after the makers narrated her character sketch and the film's story. The second female lead was yet to be finalised. Nadhiya and Kashmira Shah were confirmed as a part of the film's cast in early June 2015. Impressed by his performance in Velaiyilla Pattathari (2014), the makers cast Amitash Pradhaan to play a supporting role marking his Telugu debut. Similarly, Tamil Actor Arun Vijay was chosen to play the film's lead antagonist making his debut in Telugu after the makers were impressed with his performance in Yennai Arindhaal. Brahmaji inclusion in the film's cast was confirmed in late June 2015. Rao Ramesh confirmed his inclusion in the film's cast in early August 2015 before leaving for Bangkok for the film's shoot. Days later, Prudhviraj confirmed his inclusion in the film's cast. On 20 August 2015, Vaitla confirmed that Chiranjeevi would make a cameo appearance in the film. He added that Chiranjeevi would appear for fifteen minutes in the film. Tisca Chopra was signed to play a supporting role marking her debut in Telugu cinema.
