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.

Example Input: Question: Of the two bandmembers that left P-Funk with Haskins, which was the oldest? Passage:By 1970, the five Parliaments singers were touring with five backing musicians known separately as Funkadelic. The highly rehearsed performances and suited look of The Parliaments gave way to the members dressing in their own outrageous styles. Haskins wore long johns on stage. Due to the contractual issues surrounding the group name, Clinton signed the band as Funkadelic to Westbound Records. The ensemble released their first album Funkadelic in 1970. Clinton also renamed his group of singers Parliament (but still with the Funkadelic musicians as official members) and signed that act to the Holland-Dozier-Holland-owned record label, Invictus. Parliament released their first album Osmium in 1970. Clinton now had two groups that were actually one entity. Under the name Funkadelic, the ensemble was geared towards a rock audience, and as Parliament it was aimed at a soul music audience. Collectively, they became known as Parliament-Funkadelic, or P-Funk. Haskins contributed to P-Funk as a writer through 1972. He toured and appeared on P-Funk albums as a singer, and occasionally as a guitarist, throughout the 1970s. In June 1977 at the height of P-Funk's popularity, Haskins (along with other original Parliaments Calvin Simon and Grady Thomas) left the ensemble over financial and management disputes with Clinton.
