Input: Consider 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.

Input: Consider Input: Question: Who lived a longer life, Lucius Cornelius Sulla or Caecilius Metellus Pius? Passage:Lagos is an ancient maritime town with more than 2000 years of history. The name Lagos comes from a Celtic settlement, derived from the Latin Lacobriga, the name of the settlement was established during the pre-Punic civilizations. It became an early settlement of the Carthaginians, who recruited Celtic tribesmen in their war against the Romans (the Punic Wars). Owing to its already important harbour, it was colonized by the Romans and integrated into the Roman province of Lusitania, becoming known as Lacobriga. Quintus Sertorius, a rebellious Roman general, helped by the Lusitanians of Lacobriga (who had been oppressed under Roman Generals and members of Lucius Cornelius Sulla party), successfully defeated the Roman army of Caecilius Metellus Pius probably at nearby Monte Moliao.
