Teacher: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.
Teacher: Now, understand the problem? Solve this instance: Passage: The Conquest of Wales by Edward I, sometimes referred to as the Edwardian Conquest of Wales, took place between 1277 and 1283. It resulted in the defeat and annexation of the Principality of Wales, and the other last remaining independent Welsh principalities, by Edward I, King of England. By the 13th century Wales was divided between native Welsh principalities and the territories of the Anglo-Norman Marcher lords. The leading principality was Gwynedd whose princes had gained control of the greater part of the country, making the other remaining Welsh princes their vassals, and had taken the title Prince of Wales. Although English monarchs had made several attempts to seize control of the native Welsh territories, it was not until Edward's war of conquest against Llywelyn ap Gruffudd of 1277 to 1283 that this was achieved on a lasting basis. In two campaigns, in 1277 and 1282/1283 respectively, Edward first significantly reduced the territory of the Principality of Wales and then completely overran it, as well as the other remaining Welsh principalities. Most of the conquered territory was retained as a royal fief, and these lands subsequently became, by custom, the territorial endowment of the heir to the English throne with the title Prince of Wales. The remainder would be granted to Edward's supporters as new Marcher lordships. Although the territories would not be effectively incorporated into the Kingdom of England until the Laws in Wales Acts 1535-1542, Edward's conquest marked the end of Welsh independence.
Student:
How many years after Welsh independence ended was Wales effectively incorporated into the Kingdom of England with the Laws in Wales Acts?
