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.
Input: Passage: Friedrich Engels wrote The Peasant War in Germany , which opened up the issue of the early stages of German capitalism on later bourgeois "civil society" at the level of peasant economies. Engels' analysis was picked up in the middle 20th century by the French Annales School, and Marxist historians in East Germany and Britain. Using Karl Marx's concept of historical materialism, Engels portrayed the events of 1524-1525 as prefiguring the 1848 Revolution. He wrote, "Three centuries have passed and many a thing has changed; still the Peasant War is not so impossibly far removed from our present struggle, and the opponents who have to be fought are essentially the same. We shall see the classes and fractions of classes which everywhere betrayed 1848 and 1849 in the role of traitors, though on a lower level of development, already in 1525." Engels ascribed the failure of the revolt to its fundamental conservatism. This led both Marx and Engels to conclude that the communist revolution, when it occurred, would be led not by a peasant army but by an urban proletariat.
Output:
How many centuries passed without things changing, according to Engels?
