Input: Article: Hydropower is produced in 150 countries, with the Asia-Pacific region generating 32 percent of global hydropower in 2010. China is the largest hydroelectricity producer, with 721 terawatt-hours of production in 2010, representing around 17 percent of domestic electricity use. There are now three hydroelectricity plants larger than 10 GW: the Three Gorges Dam in China, Itaipu Dam across the Brazil/Paraguay border, and Guri Dam in Venezuela. The cost of hydroelectricity is low, making it a competitive source of renewable electricity. The average cost of electricity from a hydro plant larger than 10 megawatts is 3 to 5 U.S. cents per kilowatt-hour.

Now answer this question: Which country is the largest hydroelectricity producer?

Output: China

Input: Article: Plato describes the priestesses of Delphi and Dodona as frenzied women, obsessed by "mania" (, "frenzy"), a Greek word he connected with mantis (, "prophet"). Frenzied women like Sibyls from whose lips the god speaks are recorded in the Near East as Mari in the second millennium BC. Although Crete had contacts with Mari from 2000 BC, there is no evidence that the ecstatic prophetic art existed during the Minoan and Mycenean ages. It is more probable that this art was introduced later from Anatolia and regenerated an existing oracular cult that was local to Delphi and dormant in several areas of Greece.

Now answer this question: Who describes Delphi and Dodona as frenzied women?

Output: Plato

Input: Article: On 12 September 1944, King Peter II called on all Yugoslavs to come together under Tito's leadership and stated that those who did not were "traitors", by which time Tito was recognized by all Allied authorities (including the government-in-exile) as the Prime Minister of Yugoslavia, in addition to commander-in-chief of the Yugoslav forces. On 28 September 1944, the Telegraph Agency of the Soviet Union (TASS) reported that Tito signed an agreement with the Soviet Union allowing "temporary entry" of Soviet troops into Yugoslav territory which allowed the Red Army to assist in operations in the northeastern areas of Yugoslavia. With their strategic right flank secured by the Allied advance, the Partisans prepared and executed a massive general offensive which succeeded in breaking through German lines and forcing a retreat beyond Yugoslav borders. After the Partisan victory and the end of hostilities in Europe, all external forces were ordered off Yugoslav territory.

Now answer this question: In 1944 who called on all Yuboslavs to come together under Tito's leadership?

Output:
King Peter II
