Example Input: Question: What were the combined ages of Joseph Urban and Benjamin Wistar Morris the year that they were both hired to come up with blueprints for the house? Passage:The construction of Rockefeller Center occurred between 1932 and 1940 on land that John D. Rockefeller Jr. leased from Columbia University. The Rockefeller Center site was originally supposed to be occupied by a new opera house for the Metropolitan Opera. By 1928, Benjamin Wistar Morris and designer Joseph Urban were hired to come up with blueprints for the house. However, the new building was too expensive for the opera to fund by itself, and it needed an endowment, and the project ultimately gained the support of John D. Rockefeller Jr. The planned opera house was canceled in December 1929 due to various issues, with the new opera house eventually being built at Lincoln Center, opening in 1966.

Example Input: Question: How many copies have sold of most famous work by the author who provided the blurb for The Divine? Passage:The Divine was published in the U.S. by First Second Books, featuring a blurb by author Yann Martel, best known for the international bestseller Life of Pi. It was released in July 2015 and has hit the New York Times Best Sellers list. It has since received highly positive reviews. Publishers Weekly had chosen The Divine for "top ten graphic novel for spring 2015", describing it later on as: "Heady, hellacious, and phantasmagoric". Jesse Karp on his Booklist review wrote: "Stunning artwork and creeping dread weave together in this satisfying and moving page-turner". Douglas Wolk from The New York Times described it as "a too rare example of artists getting top billing", referring to the artwork by Asaf and Tomer Hanuka. Joshua Rivera from GQ wrote: "The Divine's story is unflinching and raw, and its art is quite possibly the most beautiful of any comic this year". Michael Mechanic from Mother Jones called it "beautifully rendered", while io9 defined it as "Your next comics obsession". Rich Barrett from Mental Floss chose it for "The most interesting comics of the week" and praised it for being "stunning, cohesive combination [of elements]". Terry Hong, from The Smithsonian Asian Pacific American Center blog, wrote: "can’t-turn-away riveting [...] Unrelenting and uninterruptible", and the Eisner nominated comics blog Comics & Cola dubbed it "superb" and chose it for its pick of the month.

Example Input: Question: In what town was the person born who was mentally challenged and in police custody in 1952? Passage:One of the most notorious cases of this type was the 1952 case in England involving Derek Bentley, a mentally challenged man who was in police custody when his sixteen-year-old companion, Christopher Craig, shot and killed a police constable during a botched break-in. Craig was sentenced to be detained at Her Majesty's Pleasure, since as a juvenile offender he could not be sentenced to death (he was released after serving ten years), but Bentley was hanged despite popular protest. The incident was dramatized in the film Let Him Have It, which is what Bentley allegedly said to Craig during the incident, which can be interpreted either as telling Craig to shoot the policeman, or to give him the gun. The hanging of Bentley led to public outrage and sparked the MP Sydney Silverman's campaign to abolish capital punishment in the United Kingdom, achieved c. 1965.
