Input: Read this: The Classical era, from about 1750 to 1820, established many of the norms of composition, presentation, and style, and was also when the piano became the predominant keyboard instrument. The basic forces required for an orchestra became somewhat standardized (although they would grow as the potential of a wider array of instruments was developed in the following centuries). Chamber music grew to include ensembles with as many as 8 to 10 performers for serenades. Opera continued to develop, with regional styles in Italy, France, and German-speaking lands. The opera buffa, a form of comic opera, rose in popularity. The symphony came into its own as a musical form, and the concerto was developed as a vehicle for displays of virtuoso playing skill. Orchestras no longer required a harpsichord (which had been part of the traditional continuo in the Baroque style), and were often led by the lead violinist (now called the concertmaster).
Question: How many muscians, at most, could make up a chamber ensemble during the classical period?

Output: 10

Input: Read this: 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.
Question: In what year did the Duke of Anjou conquered the United provinces?
