Question: When was Taylor's place of birth founded? Passage:Taylor was born in 1861 in Peckham, to John and Mary Jane Cash. He worked in stockbroker's office in London and in 1880s he emigrated to South Africa and than to Western Australia in early 1890 following the Ashburton rush. In January 1891, he settled in Southern Cross, where he worked as a merchant and stockbroker. Three years later, he moved his operations at Coolgardie, where a promising gold field had been just discovered. Sitting at the town council, he was elected on 3 August 1896 one of the three members of the Western Australian Legislative Council for the East Province. He was one of the ten Western Australia representatives at the 1897-1898 Australasian Federal Convention, which prepared the federation. He left the council in 1899 to focus on speculative developments. He made estimated 250,000 pounds in speculating in Australia, before moving back to Europe to speculate on London Stock Exchange.

Question: How many years after the Clairvaux was found, was the Margam Abbey founded? Passage:The abbey was founded in 1147 as a daughter house of Clairvaux by Robert, Earl of Gloucester, and was dedicated to the Blessed Virgin Mary. Early Christian crosses found in the close vicinity and conserved in the nearby Margam Stones Museum suggest the existence of an earlier Celtic monastic community. The founding abbot was William of Clairvaux. The third abbot, Conan, enjoyed the praise of Giraldus Cambrensis, whom he appears to have entertained prior to his official visit with Baldwin of Forde, Archbishop of Canterbury, to preach the Crusade in 1188. Conan (or Cunan) contributed to Patristic literature, as he is credited with the capitula or chapter-headings prefixing each section of St. Bernard's Sermons on the Song of Songs, one of the works for which that author was titled a Doctor of the Church.

Question: What was the population of the town attacked by the PLO and Lebanese National Movement? Passage:By the mid-1970s, Arafat and his Fatah movement found themselves in a tenuous position. Arafat increasingly called for diplomacy, perhaps best symbolized by his Ten Point Program and his support for a UN Security Council resolution proposed in 1976 calling for a two-state settlement on the pre-1967 borders. But the Rejectionist Front denounced the calls for diplomacy, and a diplomatic solution was vetoed by the United States. In 1975, the increasing tensions between Palestinian militants and Christian militias exploded into the Lebanese Civil War, involving all factions. On 20 January 1976, the PLO took part in the Damour massacre in retaliation to the Karantina massacre. The PLO and Lebanese National Movement attacked the Christian town of Damour, killing 684 civilians and forcing the remainder of the town's population to flee. In 1976 Syria joined the war by invading Lebanon, beginning the 29‑year Syrian occupation of Lebanon, and in 1978 Israel invaded South Lebanon in response to the Coastal Road Massacre, executed by Palestinian militants based in Lebanon.
