Example Input: Question: Do dragons appear in Greek Mythology outside of the chimera? Passage:The chimera of Greek mythology appeared in Marvel Comics. It is depicted as a fire-breathing monster with the heads of a lion and a goat next to each other, the front legs of a lion, the wings of a dragon, the hindquarters of a goat, and a snake-headed tail, while also possessing the power of speech. Its history of being the offspring of Echidna and being slain by Bellerophon is still mentioned. At some point, the Chimera was restored to life by Hera to guard the caverns underneath New Olympus. It was accompanied in this job by a Cyclops and some Skeleton Warriors. The Chimera encountered the Agents of Atlas. When it didn't see that they were Olympians, Chimera breathed fire at them, sparking a fight between the heroes and the minions of Hera. Gorilla-Man forced the chimera to set its second head ablaze, causing it to flail around until it was knocked unconscious.

Example Input: Question: What team did the captain that left Stoke in 2007 go to? Passage:He joined fellow Championship side Stoke City for a £225,000 fee in August 2006. He was made captain when Michael Duberry left in January 2007 and Stoke went on to narrowly miss out on a play-off place. With Stoke not being promoted Higginbotham again decided to hand in a transfer request to help force through a move to Sunderland. He spent one season at the Stadium of Light before returning to Stoke in 2008. He became a vital member of Tony Pulis' squad as Stoke established themselves in the Premier League. He scored the winning goal in the FA Cup quarter-final against West Ham United but missed out on both the semi-final and the final due to a knee injury. After his recovery he struggled to force his way back into the side and spent time out on loan to Nottingham Forest and Ipswich Town before joining Sheffield United on a free transfer in January 2013. After eight months at Bramall Lane, he left to join Conference Premier side Chester before ending his career with a short spell at Altrincham.

Example Input: Question: How many copies of the duet produced by Gary Klein were sold? Passage:Having left Casablanca Records, with whom she had had some of the biggest selling and most popular hits of the disco era in the 1970s, Summer had signed to Geffen Records in 1980 and had continued working with Giorgio Moroder and Pete Bellotte, with whom she had written the vast majority of her hits. However, label owner David Geffen had been disappointed with the chart performance of the 1980 The Wanderer, Summer's debut album for Geffen and rather than release the followup; I'm a Rainbow which Summer had recorded with Moroder/Bellotte in 1981. Geffen had Summer record a new album with Quincy Jones from whom a production credit – given Jones' track record particularly his work with Michael Jackson – Geffen felt would guarantee a commercial smash. The resultant Donna Summer album was the first time the singer had worked with a producer other than Moroder and Bellotte since 1974 save for the one-off track "Down Deep Inside (Theme from "The Deep")" which was produced by John Barry for the film The Deep, and the "No More Tears (Enough is Enough)" duet with Barbra Streisand which was co-produced by Gary Klein of The Entertainment Company.
