Question: On what date did Recitation win its maiden race at Newbury Racecourse? Passage:After finishing third over five furlongs on his racecourse debut, Recitation won a maiden race over the same distance at Newbury Racecourse, beating I'll See You by half a length. The colt was then moved up sharply in class for the Group Three Coventry Stakes over six furlongs at Royal Ascot in June in which he was ridden by Greville Starkey and started at odds of 11/1. In a performance which Timeform described as "a revelation", Recitation took the lead a quarter mile from the finish and drew clear of the field to win easily by five lengths from Motavato, Bel Bolide and Another Realm. The form of the race was subsequently boosted when the third and fourth placed horses won the Gimcrack Stakes and the Richmond Stakes respectively. In the July Stakes at Newmarket Racecourse Recitation started 2/5 favourite against two opponents, but was beaten two and a half lengths by Age Quod Agis.

Question: Is the person who served as Lebanese President during 1982 still alive? Passage:According to historians William Cleveland and Martin Bunton, Beirut became an international banking center because of its "laissez-faire economic system". Business owners from Cairo, Damascus, and Baghdad moved to Beirut for economic opportunities. Despite Lebanon's cultural liberalism and economic prosperity, sectarian tensions remained as citizens identified themselves through their sects. With Muslims calling for greater representation and with Cold War tensions, Lebanese leadership had to decide whether to ally with the West or with Egypt, Syria and its Arab history. Christians wanted to continue alliances with the West but Muslims were drawn to Nasser's pan-Arabism. Multiple factors including sectarian tensions and Palestinian refugee settlement in southern Lebanon contributed to the beginnings of the Lebanese Civil War. In 1976, Syrian President Hafez al-Assad sent troops into Lebanon to fight PLO forces on behalf of Christian militias. This led to escalated fighting until a cease-fire agreement later that year that allowed for the stationing of Syrian troops within Lebanon. The Syrian presence in Lebanon quickly changed sides; soon after they entered Lebanon they had flip-flopped and began to fight the Christian nationalists in Lebanon they allegedly entered the country to protect. The Kateab Party and the Lebanese Forces under Bachir Gemayel strongly resisted the Syrians in Lebanon. Following the Israeli invasion into Lebanon in 1982, new Lebanese President Amine Gemayel sought the support of Syrian troops to stabilize the region. Syria fought Israeli troops after the latter's invasion of Lebanon.
