Input: Economy of Greece
Energy production in Greece is dominated by the Public Power Corporation (known mostly by its acronym , or in English DEI). In 2009 DEI supplied for 85.6% of all energy demand in Greece, while the number fell to 77.3% in 2010. Almost half (48%) of DEI's power output is generated using lignite, a drop from the 51.6% in 2009. Another 12% comes from Hydroelectric power plants and another 20% from natural gas. Between 2009 and 2010, independent companies' energy production increased by 56%, from 2,709 Gigawatt hour in 2009 to 4,232 GWh in 2010.

Input: Kievan Rus%27
The expansion of the Rus' put further military and economic pressure on the Khazars, depriving them of territory, tributaries, and trade. In around 890, Oleg waged an indecisive war in the lands of the lower Dniester and Dnieper rivers with the Tivertsi and the Ulichs, who were likely acting as vassals of the Magyars, blocking Rus' access to the Black Sea. In 894, the Magyars and Pechenegs were drawn into the wars between the Byzantines and the Bulgarian Empire. The Byzantines arranged for the Magyars to attack Bulgarian territory from the north, and Bulgaria in turn persuaded the Pechenegs to attack the Magyars from their rear. Boxed in, the Magyars were forced to migrate further west across the Carpathian Mountains into the Hungarian plain, depriving the Khazars of an important ally and a buffer from the Rus'. The migration of the Magyars allowed Rus' access to the Black Sea, and they soon launched excursions into Khazar territory along the sea coast, up the Don river, and into the lower Volga region. The Rus' were raiding and plundering into the Caspian Sea region from 864, with the first large-scale expedition in 913, when they extensively raided Baku, Gilan, Mazandaran and penetrated into the Caucasus.

What year did the Rus raid Baku, Gilan,Mazandaran, and Caucasus?
Output: 913

Input: Cyprus
The Ottomans abolished the feudal system previously in place and applied the millet system to Cyprus, under which non-Muslim peoples were governed by their own religious authorities. In a reversal from the days of Latin rule, the head of the Church of Cyprus was invested as leader of the Greek Cypriot population and acted as mediator between Christian Greek Cypriots and the Ottoman authorities. This status ensured that the Church of Cyprus was in a position to end the constant encroachments of the Roman Catholic Church. Ottoman rule of Cyprus was at times indifferent, at times oppressive, depending on the temperaments of the sultans and local officials, and the island began over 250 years of economic decline.

Who was invested as the leader of the Greek Cypriot population?
Output: head of the Church of Cyprus

Input: Central African Republic
The per capita income of the Republic is often listed as being approximately $400 a year, one of the lowest in the world, but this figure is based mostly on reported sales of exports and largely ignores the unregistered sale of foods, locally produced alcoholic beverages, diamonds, ivory, bushmeat, and traditional medicine. For most Central Africans, the informal economy of the CAR is more important than the formal economy.[citation needed] Export trade is hindered by poor economic development and the country's landlocked position.[citation needed]

Which item that poachers kill elephants for can be obtained in CAR?
Output:
ivory
