Problem: Cubism:

Cubism was relevant to an architecture seeking a style that needed not refer to the past. Thus, what had become a revolution in both painting and sculpture was applied as part of "a profound reorientation towards a changed world". The Cubo-Futurist ideas of Filippo Tommaso Marinetti influenced attitudes in avant-garde architecture. The influential De Stijl movement embraced the aesthetic principles of Neo-plasticism developed by Piet Mondrian under the influence of Cubism in Paris. De Stijl was also linked by Gino Severini to Cubist theory through the writings of Albert Gleizes. However, the linking of basic geometric forms with inherent beauty and ease of industrial applicationwhich had been prefigured by Marcel Duchamp from 1914was left to the founders of Purism, Amedee Ozenfant and Charles-Edouard Jeanneret (better known as Le Corbusier,) who exhibited paintings together in Paris and published Apres le cubisme in 1918. Le Corbusier's ambition had been to translate the properties of his own style of Cubism to architecture. Between 1918 and 1922, Le Corbusier concentrated his efforts on Purist theory and painting. In 1922, Le Corbusier and his cousin Jeanneret opened a studio in Paris at 35 rue de Sevres. His theoretical studies soon advanced into many different architectural projects.

Problem: Parallel to events in Germany, a movement began in Switzerland under the leadership of Huldrych Zwingli. Zwingli was a scholar and preacher, who in 1518 moved to Zurich. Although the two movements agreed on many issues of theology, some unresolved differences kept them separate. A long-standing resentment between the German states and the Swiss Confederation led to heated debate over how much Zwingli owed his ideas to Lutheranism. The German Prince Philip of Hesse saw potential in creating an alliance between Zwingli and Luther. A meeting was held in his castle in 1529, now known as the Colloquy of Marburg, which has become infamous for its failure. The two men could not come to any agreement due to their disputation over one key doctrine.
What Prince hosted the Colloquy of Marburg?

Answer: Prince Philip of Hesse

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Although the Canadian Armed Forces are a single service, there are three similar but distinctive environmental uniforms (DEUs): navy blue (which is actually black) for the navy, rifle green for the army, and light blue for the air force. CAF members in operational occupations generally wear the DEU to which their occupation "belongs." CAF members in non-operational occupations (the "purple" trades) are allocated a uniform according to the "distribution" of their branch within the CAF, association of the branch with one of the former services, and the individual's initial preference. Therefore, on any given day, in any given CAF unit, all three coloured uniforms may be seen.
What are the "red" trades?
A: unanswerable

Problem: States of Germany:

During the Allied occupation of Germany after World War II, internal borders were redrawn by the Allied military governments. No single state comprised more than 30% of either population or territory; this was intended to prevent any one state from being as dominant within Germany as Prussia had been in the past. Initially, only seven of the pre-War states remained: Baden (in part), Bavaria (reduced in size), Bremen, Hamburg, Hesse (enlarged), Saxony, and Thuringia. The states with hyphenated names, such as Rhineland-Palatinate, North Rhine-Westphalia, and Saxony-Anhalt, owed their existence to the occupation powers and were created out of mergers of former Prussian provinces and smaller states. Former German territory that lie east of the Oder-Neisse Line fell under either Polish or Soviet administration but attempts were made at least symbolically not to abandon sovereignty well into the 1960s. However, no attempts were made to establish new states in these territories as they lay outside the jurisdiction of West Germany at that time.
