Example Input: The second Diadochi war began following the death of Antipater in 319 BC. Passing over his own son, Cassander, Antipater had declared Polyperchon his successor as Regent. Cassander rose in revolt against Polyperchon (who was joined by Eumenes) and was supported by Antigonus, Lysimachus and Ptolemy. In 317, Cassander invaded Macedonia, attaining control of Macedon, sentencing Olympias to death and capturing the boy king Alexander IV, and his mother. In Asia, Eumenes was betrayed by his own men after years of campaign and was given up to Antigonus who had him executed.
Example Output: When did Antipater die?

Example Input: Some new immigrants arrived as refugees with no possessions and were housed in temporary camps known as ma'abarot; by 1952, over 200,000 immigrants were living in these tent cities. During this period, food, clothes and furniture had to be rationed in what became known as the Austerity Period. The need to solve the crisis led Ben-Gurion to sign a reparations agreement with West Germany that triggered mass protests by Jews angered at the idea that Israel could accept monetary compensation for the Holocaust.
Example Output: What were temporary camps known as?

Example Input: The current 8–4–4 system was launched in January 1985. It put more emphasis on vocational subjects on the assumption that the new structure would enable school drop-outs at all levels either to be self-employed or to secure employment in the informal sector. In January 2003, the Government of Kenya announced the introduction of free primary education. As a result, primary school enrolment increased by about 70%. Secondary and tertiary education enrolment has not increased proportionally because payment is still required for attendance. In 2007 the government issued a statement declaring that from 2008, secondary education would be heavily subsidiszed, with the government footing all tuition fees.
Example Output:
When was the 8-4-4 system launched?
