The problem: Answer a question about this article:
The Reinvent the Toilet Challenge is a long-term research and development effort to develop a hygienic, stand-alone toilet. This challenge is being complemented by another investment program to develop new technologies for improved pit latrine emptying (called by the foundation the "Omni-Ingestor") and fecal sludge processing (called "Omni-Processor"). The aim of the "Omni Processor" is to convert excreta (for example fecal sludge) into beneficial products such as energy and soil nutrients with the potential to develop local business and revenue.

Problem: Please answer a question about the following article about Napoleon:
The initial military maneuvers began in September 1806. In a notable letter to Marshal Soult detailing the plan for the campaign, Napoleon described the essential features of Napoleonic warfare and introduced the phrase le bataillon-carré ('square battalion'). In the bataillon-carré system, the various corps of the Grande Armée would march uniformly together in close supporting distance. If any single corps was attacked, the others could quickly spring into action and arrive to help. Napoleon invaded Prussia with 180,000 troops, rapidly marching on the right bank of the River Saale. As in previous campaigns, his fundamental objective was to destroy one opponent before reinforcements from another could tip the balance of the war. Upon learning the whereabouts of the Prussian army, the French swung westwards and crossed the Saale with overwhelming force. At the twin battles of Jena and Auerstedt, fought on 14 October, the French convincingly defeated the Prussians and inflicted heavy casualties. With several major commanders dead or incapacitated, the Prussian king proved incapable of effectively commanding the army, which began to quickly disintegrate. In a vaunted pursuit that epitomized the "peak of Napoleonic warfare," according to historian Richard Brooks, the French managed to capture 140,000 soldiers, over 2,000 cannons and hundreds of ammunition wagons, all in a single month. Historian David Chandler wrote of the Prussian forces: "Never has the morale of any army been more completely shattered." Despite their overwhelming defeat, the Prussians refused to negotiate with the French until the Russians had an opportunity to enter the fight.
How many troops did Napoleon use for the invasion of Prussia?
A: 180,000

Video data may be represented as a series of still image frames. The sequence of frames contains spatial and temporal redundancy that video compression algorithms attempt to eliminate or code in a smaller size. Similarities can be encoded by only storing differences between frames, or by using perceptual features of human vision. For example, small differences in color are more difficult to perceive than are changes in brightness. Compression algorithms can average a color across these similar areas to reduce space, in a manner similar to those used in JPEG image compression. Some of these methods are inherently lossy while others may preserve all relevant information from the original, uncompressed video.

What may be represented as a series of still image frames?
Answer: Video data

Roman Catholicism was the sole established religion in the Holy Roman Empire until the Reformation changed this drastically. In 1517, Martin Luther challenged the Catholic Church as he saw it as a corruption of Christian faith. Through this, he altered the course of European and world history and established Protestantism. The Thirty Years' War (1618–1648) was one of the most destructive conflicts in European history. The war was fought primarily in what is now Germany, and at various points involved most of the countries of Europe. The war was fought largely as a religious conflict between Protestants and Catholics in the Holy Roman Empire.
Who was the thirty year war between?
Protestants and Catholics


Here is a question about this article: Shifts of international power have most notably occurred through major conflicts. The conclusion of the Great War and the resulting treaties of Versailles, St-Germain, Neuilly, Trianon and Sèvres witnessed the United Kingdom, France, Italy, Japan and the United States as the chief arbiters of the new world order. In the aftermath of World War I the German Empire was defeated, the Austria-Hungarian empire was divided into new, less powerful states and the Russian Empire fell to a revolution. During the Paris Peace Conference, the "Big Four"—France, Italy, United Kingdom and the United States—held noticeably more power and influence on the proceedings and outcome of the treaties than Japan. The Big Four were leading architects of the Treaty of Versailles which was signed by Germany; the Treaty of St. Germain, with Austria; the Treaty of Neuilly, with Bulgaria; the Treaty of Trianon, with Hungary; and the Treaty of Sèvres, with the Ottoman Empire. During the decision-making of the Treaty of Versailles, Italy pulled out of the conference because a part of its demands were not met and temporarily left the other three countries as the sole major architects of that treaty, referred to as the "Big Three".
What is the answer to this question: What marked the conclusion of The Great War?
****
So...
treaties of Versailles, St-Germain, Neuilly, Trianon and Sèvres
