Input: Article: Since the 19th century, the built-up area of Paris has grown far beyond its administrative borders; together with its suburbs, the whole agglomeration has a population of 10,550,350 (Jan. 2012 census). Paris' metropolitan area spans most of the Paris region and has a population of 12,341,418 (Jan. 2012 census), or one-fifth of the population of France. The administrative region covers 12,012 km² (4,638 mi²), with approximately 12 million inhabitants as of 2014, and has its own regional council and president.

Now answer this question: What is the aggregate population of Paris?

Output: 10,550,350

Input: Article: In the human digestive system, food enters the mouth and mechanical digestion of the food starts by the action of mastication (chewing), a form of mechanical digestion, and the wetting contact of saliva. Saliva, a liquid secreted by the salivary glands, contains salivary amylase, an enzyme which starts the digestion of starch in the food; the saliva also contains mucus, which lubricates the food, and hydrogen carbonate, which provides the ideal conditions of pH (alkaline) for amylase to work. After undergoing mastication and starch digestion, the food will be in the form of a small, round slurry mass called a bolus. It will then travel down the esophagus and into the stomach by the action of peristalsis. Gastric juice in the stomach starts protein digestion. Gastric juice mainly contains hydrochloric acid and pepsin. As these two chemicals may damage the stomach wall, mucus is secreted by the stomach, providing a slimy layer that acts as a shield against the damaging effects of the chemicals. At the same time protein digestion is occurring, mechanical mixing occurs by peristalsis, which is waves of muscular contractions that move along the stomach wall. This allows the mass of food to further mix with the digestive enzymes.

Now answer this question: What is the definition of bolus?

Output: a small, round slurry mass

Input: Article: When a historic document survives only in translation, the original having been lost, researchers sometimes undertake back-translation in an effort to reconstruct the original text. An example involves the novel The Saragossa Manuscript by the Polish aristocrat Jan Potocki (1761–1815), who wrote the novel in French and anonymously published fragments in 1804 and 1813–14. Portions of the original French-language manuscript were subsequently lost; however, the missing fragments survived in a Polish translation that was made by Edmund Chojecki in 1847 from a complete French copy, now lost. French-language versions of the complete Saragossa Manuscript have since been produced, based on extant French-language fragments and on French-language versions that have been back-translated from Chojecki’s Polish version.

Now answer this question: When had Edmund Chojecki translated portions of the Saragossa Manuscript into Polish from French?

Output:
1847
