Question: What were the points made in the program Arafat wrote to promote diplomacy in the 1970s? 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: How old was Pope Urban VI when Nerio Acciaioli was captured near Vostitsa? Passage:On 6 September that year, Pope Urban VI declared that as James of Baux's successors had forfeited their rights to the Holy See, the principality belonged to him and he devolved its government on Paul Foscari, the archbishop of Patras, who in turn made Pedro vicar general. Pedro was constantly at war with the Despotate of Morea, against whom he even used Ottoman pirates, and the Duchy of Athens under Nerio I Acciaioli. The latter was captured near Vostitsa on 10 September 1389 while trying to sit to talks with Pedro concerning Argos and Nauplia. He had to buy his freedom with concessions to the Navarrese ally, Venice. Late in 1394 or early in 1395, the Turkish general Evrenos Beg invaded the despotate and met Pedro's forces at Leontari. Together the two besieged and took Akova (28 February). After Evrenos returned to Thessaly, Pedro was defeated by the Greeks and taken captive with the grand constable Andronico Asano Zaccaria, his brother-in-law. In December, Venice paid 50,000 hyperpers for the release of her allies.
