Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.

Let me give you an example: In 1582 the united provinces invited francis, duke of anjou to lead them; but after a failed attempt to take antwerp in 1583, the duke left the netherlands again. after the assassination of william of orange (10 july 1584), both henry iii of france and elizabeth i of england declined the offer of sovereignty. however, the latter agreed to turn the united provinces into a protectorate of england (treaty of nonsuch, 1585), and sent the earl of leicester as governor-general. this was unsuccessful and in 1588 the provinces became a confederacy. the union of utrecht is regarded as the foundation of the republic of the seven united provinces, which was not recognized by the spanish empire until the peace of westphalia in 1648.
The answer to this example can be: In what year did francis, duke of anjou leave the netherlands?
Here is why: The generated question is perfect. Because the question is based on second sentence of the input passage and its answer is 1583.

In 1545, Polin was on his way to fight against the English in the area of Boulogne. While in Marseilles in 1545, Polin was involved as a leader in the massacre of the Protestant Waldensians . Outside the Piedmont the Waldenses joined the local Protestant churches in Bohemia, France and Germany. After they came out of clandestinity and reports were made of sedition on their part, the French king, Francis I issued on 1 January 1545 the "Arret de Merindol", and armed a crusade against the Waldensians of Provence. The leaders in the 1545 massacres were Jean Maynier d'Oppede, First President of the parlement of Provence, and Antoine Escalin des Aimars who was returning from the Italian Wars with 2,000 veterans, the Bandes de Piemont. Deaths ranged from hundreds to thousands, depending on the estimates, and several villages were devastated.
Answer:
