Example Input: Question: Where is the company that Bech worked as a developer during 1990 located? Passage:Joergen Bech, who previously worked as a developer at Innerprise Software during 1990, decided to work once again as a game programmer after dropping out of international marketing studies in 1994 and landed for the job by one of his contacts who had connection with an employee at Bethesda Softworks, who are best known for The Elder Scrolls and their most recent Fallout titles. Bethesda was interested in expanding their business to video game consoles and Joergen was hired for work on the Jaguar, due to the company receiving free Alpine Development Kits from Atari Corporation and for its superior hardware compared with other systems at the time such as the Sega Genesis and Super NES. Originally he was tasked in making a conversion of a basketball game from PC but decided to create a 2D title in order to understand the Jaguar's hardware, along with another programmer who already was familiarized with the system, after Joergen deemed the PC basketball game as a "steep learning curve" to convert, due to it being in pseudo-3D and being written on C language, which he had little to no experience with them and it was then decided that he should port Protector to Genesis, which was a conversion of Datastorm for Amiga alongside with the original authors of the game at Bethesda's Media Technology division on Denmark, with him providing the sound driver for the port, but otherwise he was not fully involved with the project and although completed it was ultimately never published due to many console, PC and multimedia titles competing for shelf space, with no prototypes of the Genesis version of Protector being found to date.

Example Input: Question: What was the population of Norwood the year that Ken Livingstone got elected to represent it? Passage:Born in Lambeth, South London, to a working-class family, Livingstone joined Labour in 1968 and was elected to represent Norwood at the GLC in 1973, Hackney North and Stoke Newington in 1977, and Paddington in 1981. That year, Labour representatives on the GLC elected him as the council's leader. Attempting to reduce London Underground fares, his plans were challenged in court and declared unlawful; more successful were his schemes to benefit women and underprivileged minorities, despite stiff opposition. The mainstream media gave him the moniker "Red Ken" in reference to his socialist beliefs and heavily criticised him for supporting controversial issues like republicanism, LGBT rights, and a United Ireland. Livingstone was a vocal opponent of the Conservative Party government of Prime Minister Margaret Thatcher, which in 1986 abolished the GLC. Elected as MP for Brent East in 1987, he became closely associated with anti-racist campaigns. He unsuccessfully stood for Labour Party leader on a leftist platform in 1992 and 1994, in the latter losing to Tony Blair. Livingstone became a vocal critic of Blair's New Labour project that pushed the party closer to the centre and won the 1997 general election.
