Teacher: Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.
Teacher: Now, understand the problem? If you are still confused, see the following 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.
Solution: In what year did francis, duke of anjou leave the netherlands?
Reason: The generated question is perfect. Because the question is based on second sentence of the input passage and its answer is 1583.

Now, solve this instance: The Rebellion was the career highlight for both leaders; Cumberland resigned from the Army in 1757 and died of a stroke in 1765. Charles was initially treated as a hero on his return to Paris but the Stuarts were once again barred from France by the 1748 Treaty of Aix-la-Chapelle. Henry Stuart's entry into the Catholic Church in June 1747 was seen as tacit acceptance the Jacobites were finished and Charles never forgave him. He continued attempts to reignite the cause, including a secret visit to London in 1750 but habitual heavy drinking made him argumentative and hard to work with. In 1759, he met French Chief Minister de Choiseul to discuss another invasion attempt but Choiseul dismissed him as incapable through drink. When his father James died in 1766, Pope Clement XIII refused to recognise him as Charles III, despite the strong objections of his brother Henry. Charles never visited Britain again and died in Rome in January 1788, a disappointed and embittered man.
Student:
Which happened first, Charles secret visit to London or his meeting with French Chief Minister de Choiseul?
