Definition: This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning).
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.
Input: Passage: King Ottokar II of Bohemia improved fortifications and rebuilt the royal palace for the purposes of representation and housing. In the 14th century, under the reign of Charles IV the royal palace was rebuilt in Gothic style and the castle fortifications were strengthened. In place of rotunda and basilica of St. Vitus began building of a vast Gothic church, that were completed almost six centuries later. During the Hussite Wars and the following decades, the castle was not inhabited. In 1485, King Ladislaus II Jagello began to rebuild the castle. The massive Vladislav Hall was added to the Royal Palace. New defence towers were also built on the north side of the castle. A large fire in 1541 destroyed large parts of the castle. Under the Habsburgs, some new buildings in Renaissance style were added. Ferdinand I built the Belvedere as a summer palace for his wife Anne. Rudolph II used Prague Castle as his main residence. He founded the northern wing of the palace, with the Spanish Hall, where his precious art collections were exhibited. The Second Defenestration of Prague in 1618 took place at the castle and began the Bohemian Revolt. During the subsequent wars, the Castle was damaged and dilapidated. Many works from the collection of Rudolph II were looted by Swedes in 1648, in the Battle of Prague which was the final act of the Thirty Years' War. The last major rebuilding of the castle was carried out by Empress Maria Theresa in the second half of the 18th century. Following his abdication in 1848, and the succession of his nephew, Franz Joseph, to the throne, the former emperor, Ferdinand I, made Prague Castle his home.
Output:
A fire destroyed part of what castle?
