Input: Dialect
The extent to which the dialects are spoken varies according to a number of factors: In Northern Germany, dialects are less common than in the South. In cities, dialects are less common than on the countryside. In a public environment, dialects are less common than in a familiar environment.

In what environment are dialects less common?
Output: public

Input: Sumer
According to Archibald Sayce, the primitive pictograms of the early Sumerian (i.e. Uruk) era suggest that "Stone was scarce, but was already cut into blocks and seals. Brick was the ordinary building material, and with it cities, forts, temples and houses were constructed. The city was provided with towers and stood on an artificial platform; the house also had a tower-like appearance. It was provided with a door which turned on a hinge, and could be opened with a sort of key; the city gate was on a larger scale, and seems to have been double. The foundation stones or rather bricks of a house were consecrated by certain objects that were deposited under them."

What were the foundation stones of Sumerian houses consecrated by?
Output: objects that were deposited under them

Input: Napoleon
On 1 April, Alexander addressed the Senat conservateur. Long docile to Napoleon, under Talleyrand's prodding it had turned against him. Alexander told the Senat that the Allies were fighting against Napoleon, not France, and they were prepared to offer honorable peace terms if Napoleon were removed from power. The next day, the Senat passed the Acte de decheance de l'Empereur ("Emperor's Demise Act"), which declared Napoleon deposed. Napoleon had advanced as far as Fontainebleau when he learned that Paris was lost. When Napoleon proposed the army march on the capital, his senior officers and marshals mutinied. On 4 April, led by Ney, they confronted Napoleon. Napoleon asserted the army would follow him, and Ney replied the army would follow its generals. While the ordinary soldiers and regimental officers wanted to fight on, without any senior officers or marshals any prospective invasion of Paris would have been impossible. Bowing to the inevitable, on 4 April Napoleon abdicated in favour of his son, with Marie-Louise as regent. However, the Allies refused to accept this under prodding from Alexander, who feared that Napoleon might find an excuse to retake the throne. Napoleon was then forced to announce his unconditional abdication only two days later.

Where had Napoleon advanced to when he received word that Paris was lost?
Output: Fontainebleau

Input: History of science
Perhaps the most prominent, controversial and far-reaching theory in all of science has been the theory of evolution by natural selection put forward by the British naturalist Charles Darwin in his book On the Origin of Species in 1859. Darwin proposed that the features of all living things, including humans, were shaped by natural processes over long periods of time. The theory of evolution in its current form affects almost all areas of biology. Implications of evolution on fields outside of pure science have led to both opposition and support from different parts of society, and profoundly influenced the popular understanding of "man's place in the universe". In the early 20th century, the study of heredity became a major investigation after the rediscovery in 1900 of the laws of inheritance developed by the Moravian monk Gregor Mendel in 1866. Mendel's laws provided the beginnings of the study of genetics, which became a major field of research for both scientific and industrial research. By 1953, James D. Watson, Francis Crick and Maurice Wilkins clarified the basic structure of DNA, the genetic material for expressing life in all its forms. In the late 20th century, the possibilities of genetic engineering became practical for the first time, and a massive international effort began in 1990 to map out an entire human genome (the Human Genome Project).

What was the name of the book that Darwin wrote about evolution?
Output:
On the Origin of Species
