Input: Consider Input: 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.

Input: Consider Input: Question: Who did Eintracht Frankfurt defeat in the 1959 German Championship? Passage:His club was Eintracht Frankfurt with whom he won the 1959 German Championship, and in 1960 reached the finals of Champion's Cup against Real Madrid. The left-footed Don Alfredo was the head of the team. Pfaff was a true playmaker with exceptionally good ball control and great skills at free kicks. Pfaff probably would have accumulated more than seven caps if Fritz Walter had not played the same role for West Germany as Pfaff played for Eintracht Frankfurt. In 1954, Atlético Madrid offered him 180,000 D-Mark but his wife Edith was against a move to Spain. Possibly Pfaff's greatest game was the 6–1 against Rangers F.C. in the 1959–60 semifinal first leg of the European Champion Clubs' Cup, which was followed by a 6–3 win of Eintracht Frankfurt in Glasgow in the second leg. He ended his career in 1962 at the age of 36.

Input: Consider Input: Question: When did the person who von Blumenthal served under  in the First Schleswig War first achieve their rank?  Passage:Brought up on his grandfather's estate at Reddentin, where his uncle Gustav von Below was founding what would become the Pentecostal movement, von Blumenthal was educated at the military schools of Culm and Berlin. He entered the Guards as 2nd lieutenant in 1827. He studied at the Berlin General War School (later called the Prussian Military Academy). After serving in the Rhine Province, he joined the topographical division of the general staff in 1846. As lieutenant of the 31st foot, he took part in 1848 in the suppression of the Berlin riots, and in 1849 was promoted captain on the general staff. The same year he served on the staff of General Eduard von Bonin in the First Schleswig War, and so distinguished himself, particularly at Fredericia, that he was appointed chief of the staff of the Schleswig-Holstein army, when the previous chief of staff, Captain von Delius, was killed.
