instruction:
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.
question:
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 Enriquez, 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 realmsthe Crown of Aragonas 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.

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

question:
Passage: Salin turned out to be the last battle of the war. After the successive battlefield defeats, the bickering between the Confederation's two main powers broke out in full force. Sawlon II of Mohnyin, who had only grudgingly agreed to Hkonmaing's takeover of the Ava throne, blamed Hkonmaing for the defeats, and now planned to put Sithu Kyawhtin I of Salin on the Ava throne. In April/May 1545, Sawlon II sent Sithu Kyawhtin with an army , which went on to occupy Sagaing, the city directly across the Irrawaddy from Ava. During the rainy season, c. September 1545, Hkonmaing died, and was succeeded by his son Narapati III. The new king promptly sent a mission to Pegu to secure friendly relations in exchange for his recognition of the new de facto border between the two kingdoms. Tabinshwehti accepted the offer. Toungoo's decisive victory gave the upstart kingdom control of all of central Burma, and cemented its emergence as the largest polity in Burma since the fall of Pagan Empire in 1287. Indeed, "there was once more a king in Burma". In the following years, Ava and Mohnyin-backed Sagaing would be locked in a war until 1551, while an emboldened Toungoo would turn its attention to conquering Arakan in 1545-47, and Siam in 1547-49.
answer:
For how many years did Toungoo try to conquer Arakan?
