Example Input: Question: What is the location of the headquarters for the company Bremer Broadcasting sold its station to in 1957? Passage:On October 6, 1957, Bremer Broadcasting announced it had sold its stations for $3.5 million to National Telefilm Associates (NTA), an early distributor of motion pictures for television, joining its NTA Film Network. On May 7, 1958, channel 13's call sign was changed to WNTA-TV to reflect the new ownership; the radio stations also adopted these call letters. NTA's cash resources enabled WNTA-TV to produce a schedule of programming with greater emphasis on the people and events of New Jersey, compared to the other commercial television stations. NTA also sought to make channel 13 the center of a new commercial network, though during its run the NTA Film Network offered only one night of "in-pattern" network programming, Friday nights in 1957–58, and for most purposes WNTA served as the New York showcase for nationally syndicated programming and produced several such entries, notably the anthology drama series Play of the Week; the talk show Open End, hosted by David Susskind; children's show The Magic Clown; and a popular dance program emceed by Clay Cole. The station continued to lag behind New York's other independent stations—WNEW-TV (channel 5), WOR-TV (channel 9) and WPIX (channel 11)—in terms of audience size, and NTA incurred a large debt load. National Telefilm Associates put the WNTA stations up for sale in February 1961.

Example Input: Question: How many Boy Wonder's have there been? Passage:Besides the aforementioned death of Stephanie Brown, many other side effects came about from this event. The biggest of these included Black Mask becoming the single crime boss in Gotham, something that would remain until his death at the hands of Catwoman. Another would be Commissioner Akins effectively making all vigilantes criminals, a move that would stay in place for over a year until the return of Commissioner Gordon to the Gotham City Police Department. The more controversial effect, not seen until the follow-up story War Crimes, was turning Doctor Leslie Thompkins against Batman, when she allows Stephanie Brown to die from her wounds as Batman's "punishment" for including children in his war on crime. Jason Todd, a former Boy Wonder, confirmed to be alive on  as a violent vigilante the Red Hood who waged a one-man war against Black Mask and successfully crippling his criminal operation in the city before seeking revenge towards Batman and the Joker. Finally, the citizens of Gotham City no longer consider Batman to be an urban legend (which has been in place since Zero Hour), as he was caught on camera trying to save the life of a wounded student at the end of Act One. Additionally, Barbara Gordon lost the clock tower that served as her home and headquarters and left Gotham City, eventually moving to Metropolis. She would later re-establish her ties to Batman.
