Question: Of the two massacres that took place in 1976, who was the PLO targeting? 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.

Question: When was the stadium where Olympique Lyonnais began their league campaign constructed? Passage:Olympique Lyonnais began their league campaign on the road taking on Le Mans at the Stade Léon-Bollée. Lyon started off the match very slow and eventually allowed a goal that was scored by Modibo Maïga in just the 21st minute. Lyon responded just seven minutes later with a goal from the converted defender Mathieu Bodmer, who equalized on a shot at the top of the box as a result of a great pass from Lisandro López. Following the break, Le Mans came out quickly in the attack and were awarded a questionable penalty by referee Lionel Jaffredo. The young Mathieu Coutadeur converted the penalty giving the home team a 2–1 lead. In the ensuing minutes, Lyon slowly lost focus, but were eventually revived when new signing Bafétimbi Gomis came on in the 77th minute. Their newfound attack still drew no goals and heading into the injury time session, Lyon were awarded a free kick just outside the penalty box. With new signings and free kick specialists Michel Bastos and López both standing over the ball, it was the latter who took it and placed the ball easily into the back of the net drawing the match at 2–2 and giving Lyon their first point of the season. Lyon's first at home was against Valenciennes. With a pivotal Champions League match coming up early next week and Jérémy Toulalan also going on international duty, he was partially rested for the match, which featured the midfield combination of Jean Makoun and Kim Källström. Lyon won the match 1–0 with a goal from Gomis, his first with the club, in the 37th minute. The goal was assisted on by Michel Bastos. The victory initially moved Lyon into fourth-place, but after the next day's matches, Lyon fell to eighth. The following week, Lyon faced Auxerre on the road. After their strong performance mid-week in the Champions League, manager Claude Puel implemented exactly the same formation, albeit with different players in certain positions. Despite missing several goal opportunities mid-week, César Delgado responded by dishing out two assists, the first on the club's opening goal scored by Jean-Alain Boumsong, who was making his season debut, and the club's second goal, scored by Miralem Pjanić, his first career league goal for the club. Lyon won the match 3–0. The Auxerre match was notable as it marked the debut of the highly rated 17-year-old Ishak Belfodil, who came on as a substitute in the 84th minute. The next week, Lyon returned home and were victors again claiming a 3–1 victory over Nancy, with all three Lyon goals coming from new signings Bastos, López and Gomis.
