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.

Passage: When Elizabeth I succeeded her half-sister Mary as Queen of England in 1558, her accession was disputed due to the questioned legitimacy of the marriage of the Queen's parents - Henry VIII and Anne Boleyn. Under Henry VIII and his advisor Thomas Cromwell, power was gradually shifted from regional institutions to royal control. This course was encouraged by Elizabeth's counsellors such as William Cecil and a policy of centralization was the approach favoured by Elizabeth herself at least in regards to the northern border region. Opponents of Elizabeth looked to Mary, Queen of Scots, as the descendant of Henry's sister Margaret Tudor. The claims were initially put forward by Mary's father-in-law, King Henry II of France, but Mary upheld them after her return to Scotland in 1561. Many English Catholics, then a significant portion of the population, supported Mary's claim as a way to restore Catholic ideology. This position was especially strong in Northern England, where several powerful nobles were Catholics; there had been similar risings against Henry VIII; the Pilgrimage of Grace of 1536 and Bigod's Rebellion of 1537. Supporters of Mary hoped for aid from France and possibly Spain . Mary's position was strengthened by the birth of her son, James, in 1566 but weakened again when she was deposed in July 1567.
How many years between Mary's position was strengthened by the birth of her son, James until she was diposed?
