Task: Question Generation
Input (English): Passage: Marco Antonio Barbaro, the Venetian bailo who had been imprisoned since 1570, conducted the negotiations. In view of the Republic's inability to regain Cyprus, the resulting treaty, signed on 7 March 1573, confirmed the new state of affairs: Cyprus became an Ottoman province, and Venice paid an indemnity of 300,000 ducats. In addition, the border between the two powers in Dalmatia was modified by the Turkish occupation of small but important parts of the hinterland that included the most fertile agricultural areas near the cities, with adverse effects on the economy of the Venetian cities in Dalmatia. Peace would continue between the two states until 1645, when a long war over Crete would break out. Cyprus itself remained under Ottoman rule until 1878, when it was ceded to Britain as a protectorate. Ottoman sovereignty continued until the outbreak of World War I, when the island was annexed by Britain, becoming a crown colony in 1925.
Output (English): How many years passed between the resulting treaty and the long war over Crete?
