Example Input: Question: Was the Social Democratic Party around when Knochel was conscripted into the Imperial Army? Passage:Wilhelm Knöchel was born into a Social Democratic working class family in Offenbach, a short distance upriver from Frankfurt. He qualified and worked as a factory machine operator ("Dreher"). In 1917 he was conscripted into the Imperial Army, shortly after which he was badly wounded. There are also references to his having worked as a mines maintenance engineer ("Grubenschlosser"). In 1919, with Germany affected by acute economic hardship and, especially in the cities, a succession of revolutionary uprisings, Knöchel joined the Social Democratic Party ("Sozialdemokratische Partei Deutschlands" / SPD). By 1920 he had relocated in search of work to the industrially vital and internationally critical Ruhr region. Sources differ over whether it was in 1920 or 1923 that he switched to the recently created Communist Party. Between 1924 and 1930 he was a member of the party leadership team for the Dortmund region ("...des Unterbezirk Dortmund"). In 1930, following the death of his first wife, he returned to Offenbach, where it was arranged that his daughter should be brought up by relatives. Knöchel was now employed as a party official.

Example Input: Question: Before the year 2000, which of the films Nikhil–Vinay's had the highest grossing box office sales? Passage:Nikhil and Vinay are both trained in classical music. Singer Anuradha Paudwal discovered the duo and recommended them to Gulshan Kumar, owner of T-Series music company, and director Chandra Barot, who signed them for the 1991 romantic film Pyar Bhara Dil. The song "Banke Kitab Teri" from the film became popular. The duo then went on to compose music for over 20 films. Their initial successes included Bewafa Sanam (1995), a film which was breakthrough for playback singer Sonu Nigam, English Babu Desi Mem (1996), Uff Yeh Mohabbat (1997) and Papa The Great (2000). The duo composed music for two of Sonu Nigam's successful music albums, Jaan (1999) and Yaad (2001). They went on to score music for Anubhav Sinha's box office success Tum Bin which included hit songs such as "Koi Fariyaad", "Chhoti Choti Raatein" and "Tumhare Siva". Some of their other successful ventures include Hum Tumhare Hain Sanam, Aapko Pehle Bhi Kahin Dekha Hai, Muskaan and Kuch Dil Ne Kaha. The duo have also been accused of plagiarism by Pakistani singer Faisal Latif.

Example Input: Question: Where there any other titles of horror-comics created by DC? Passage:Continuing to work for DC Comics during this sojourn, while also contributing the occasional story to Warren Publishing's black-and-white horror-comics magazines (including the Don Glut-scripted "Goddess from the Sea" in Vampirella #1, Sept. 1969), Adams had his first collaboration on Batman with writer Dennis O'Neil. The duo, under the direction of editor Julius Schwartz, would revitalize the character with a series of noteworthy stories reestablishing Batman's dark, brooding nature and taking the books away from the campy look and feel of the 1966–68 ABC TV series. Their first two stories were "The Secret of the Waiting Graves" in Detective Comics #395 (Jan. 1970) and "Paint a Picture of Peril" in issue #397 (March 1970), with a short Batman backup story, written by Mike Friedrich, coming in-between, in Batman #219 (Feb. 1970). Adams introduced new characters to the Batman mythos beginning with Man-Bat co-created with writer Frank Robbins in Detective Comics #400 (June 1970). O'Neil and Adams' creation Ra's al Ghul was introduced in the story "Daughter of the Demon" in Batman #232 (June 1971) and the character would later become one of Batman's most common adversaries. The same creative team would revive Two-Face in Batman #234 (Aug. 1971) and revitalize the Joker in "The Joker's Five-Way Revenge!" in Batman #251 (Sept. 1973), a landmark story bringing the character back to his roots as a homicidal maniac who murders people on a whim and delights in his mayhem.
