Detailed Instructions: 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.
Problem:Passage: Under the Capetian dynasty the French monarchy slowly began to expand its authority over the nobility, growing out of the Ile-de-France to exert control over more of the country in the 11th and 12th centuries. They faced a powerful rival in the Duke of Normandy, who in 1066 under William the Conqueror (duke 10351087), conquered England (r. 106687) and created a cross-channel empire that lasted, in various forms, throughout the rest of the Middle Ages. Normans also settled in Sicily and southern Italy, when Robert Guiscard (d. 1085) landed there in 1059 and established a duchy that later became the Kingdom of Sicily. Under the Angevin kings of England of (r. 115489) and his son Richard I of England (r. 118999), the kings of England ruled over England and large areas of France, brought to the family by Henry IIs marriage to Eleanor of Aquitaine (d. 1204), heiress to much of southern France. Richards younger brother John, King of England (r. 11991216) lost Normandy and the rest of the northern French possessions in 1204 to the French King Philip II of France (r. 11801223). This led to dissension among the English nobility, while Johns financial exactions to pay for his unsuccessful attempts to regain Normandy led in 1215 to Magna Carta, a charter that confirmed the rights and privileges of free men in England. Under (r. 121672), Johns son, further concessions were made to the nobility, and royal power was diminished. The French monarchy continued to make gains against the nobility during the late 12th and 13th centuries, bringing more territories within the kingdom under the kings personal rule and centralising the royal administration. Under Louis IX of France (r. 122670), royal prestige rose to new heights as Louis served as a mediator for most of Europe.
Solution:
How many years later did the Duke of Normandy conquer England after Robert Guiscard landed in Sicily?
