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.

Q: Passage: When the war started, John II had been King of Navarre since 1425 through his first wife, Blanche I of Navarre, who had married him in 1420. When Blanche died in 1441, John retained the government of her lands and dispossessed his own eldest son, Charles , who was made Prince of Viana in 1423. John tried to assuage his son with the lieutenancy of Navarre, but his son's French upbringing and French allies, the Beaumonteses, brought the two into conflict. In the early 1450s they were engaged in open warfare in Navarre. Charles was captured and released; and John tried to disinherit him by illegally naming his daughter Eleanor, who was married to Gaston IV of Foix, his successor. In 1451 John's new wife, Juana Enríquez, gave birth to a son, Ferdinand. In 1452 Charles fled his father first for France, later for the court of his uncle, John's elder brother, Alfonso V at Naples. From 1454 John governed his brother's Spanish realms—the Crown of Aragon—as lieutenant. When Alfonso died in 1458, Charles was arrested and brought to Majorca. John succeeded Alfonso as ruler of the Crown of Aragon. In his will John named Charles as his heir. Among John's early unpopular acts was to quit the war against Genoa, upsetting the merchants of Barcelona. He also refused to aid his nephew, Ferdinand I of Naples, in securing his throne.

A: How many years after Blanche died did John II have his son Ferdinand?

Q: Passage: Today, on the site of the martyrdom of the hot throne, there is the statue of The Virgin Mary, built by architect László Székely and sculptor György Kiss. According to the legend, during György Dózsa's torture, some monks saw in his ear the image of Mary. The first statue was raised in 1865, with the actual monument raised in 1906.  Hungarian opera composer Ferenc Erkel wrote an opera, Dózsa György, about him. His revolutionary image and Transylvanian background were drawn upon during the Communist regime of Gheorghe Gheorghiu-Dej. The Hungarian component of his movement was downplayed, but its strong anti-feudal character was emphasized. In Budapest, a square, a busy six-lane avenue, and a metro station bear his name, and it is one of the most popular street names in Hungarian villages. A number of streets in several cities of Romania were named Gheorghe Doja. Also, a number of streets in serval cities of Serbia were named "Ulica Doža Đerđa".Two Postage stamps were issued in his honor by Hungary on 12 June 1919 and on 15 March 1947, the latter in the "social revolutionists" series.

A: How many places in Budapest bear Gheorghe Gheorghiu-Dej name?
