Input: Article: St. John's, and the province as a whole, was gravely affected in the 1990s by the collapse of the Northern cod fishery, which had been the driving force of the provincial economy for hundreds of years. After a decade of high unemployment rates and depopulation, the city's proximity to the Hibernia, Terra Nova and White Rose oil fields has led to an economic boom that has spurred population growth and commercial development. As a result, the St. John's area now accounts for about half of the province's economic output.

Now answer this question: How long did unemployment rates and depopulation suffer in St. John's?

Output: decade

Here is a question about this article: Digestion begins in the mouth with the secretion of saliva and its digestive enzymes. Food is formed into a bolus by the mechanical mastication and swallowed into the esophagus from where it enters the stomach through the action of peristalsis. Gastric juice contains hydrochloric acid and pepsin which would damage the walls of the stomach and mucus is secreted for protection. In the stomach further release of enzymes break down the food further and this is combined with the churning action of the stomach. The partially digested food enters the duodenum as a thick semi-liquid chyme. In the small intestine, the larger part of digestion takes place and this is helped by the secretions of bile, pancreatic juice and intestinal juice. The intestinal walls are lined with villi, and their epithelial cells is covered with numerous microvilli to improve the absorption of nutrients by increasing the surface area of the intestine.
What is the answer to this question: What is food formed into before it is swallowed?
****
So... a bolus

The word "emotion" dates back to 1579, when it was adapted from the French word emouvoir, which means "to stir up". The term emotion was introduced into academic discussion to replace passion.

Another line of research asks about languages other than English, and one interesting finding is that many languages have a similar but not identical term
When did the word emotion enter the English language?

Problem: Please answer a question about the following article about Czech language:
One study showed that Czech and Slovak lexicons differed by 80 percent, but this high percentage was found to stem primarily from differing orthographies and slight inconsistencies in morphological formation; Slovak morphology is more regular (when changing from the nominative to the locative case, Praha becomes Praze in Czech and Prahe in Slovak). The two lexicons are generally considered similar, with most differences in colloquial vocabulary and some scientific terminology. Slovak has slightly more borrowed words than Czech.
How much do the lexicons of Czech and Slovak differ, according to on study?
A: by 80 percent

Question: Read this and answer the question

All of Chopin's compositions include the piano. Most are for solo piano, though he also wrote two piano concertos, a few chamber pieces, and some songs to Polish lyrics. His keyboard style is highly individual and often technically demanding; his own performances were noted for their nuance and sensitivity. Chopin invented the concept of instrumental ballade. His major piano works also include mazurkas, waltzes, nocturnes, polonaises, etudes, impromptus, scherzos, preludes and sonatas, some published only after his death. Influences on his compositional style include Polish folk music, the classical tradition of J. S. Bach, Mozart and Schubert, the music of all of whom he admired, as well as the Paris salons where he was a frequent guest. His innovations in style, musical form, and harmony, and his association of music with nationalism, were influential throughout and after the late Romantic period.

What instrument did every composition by Frederic include?
Answer:
piano
