Input: Frederic Chopin
At the age of 21 he settled in Paris. Thereafter, during the last 18 years of his life, he gave only some 30 public performances, preferring the more intimate atmosphere of the salon. He supported himself by selling his compositions and teaching piano, for which he was in high demand. Chopin formed a friendship with Franz Liszt and was admired by many of his musical contemporaries, including Robert Schumann. In 1835 he obtained French citizenship. After a failed engagement to Maria Wodzinska, from 1837 to 1847 he maintained an often troubled relationship with the French writer George Sand. A brief and unhappy visit to Majorca with Sand in 183839 was one of his most productive periods of composition. In his last years, he was financially supported by his admirer Jane Stirling, who also arranged for him to visit Scotland in 1848. Through most of his life, Chopin suffered from poor health. He died in Paris in 1849, probably of tuberculosis.

At what age did Chopin move to Paris?
Output: 21

Input: Article: Despite these detailed standard definitions, cameras typically do not clearly indicate whether the user "ISO" setting refers to the noise-based speed, saturation-based speed, or the specified output sensitivity, or even some made-up number for marketing purposes. Because the 1998 version of ISO 12232 did not permit measurement of camera output that had lossy compression, it was not possible to correctly apply any of those measurements to cameras that did not produce sRGB files in an uncompressed format such as TIFF. Following the publication of CIPA DC-004 in 2006, Japanese manufacturers of digital still cameras are required to specify whether a sensitivity rating is REI or SOS.[citation needed]

Now answer this question: What measures might the user "ISO" setting correspond to?

Output: the noise-based speed, saturation-based speed, or the specified output sensitivity, or even some made-up number for marketing purposes

Article: Western Europe's largest Jewish community, and the third-largest Jewish community in the world, can be found in France, home to between 483,000 and 500,000 Jews, the majority of whom are immigrants or refugees from North African Arab countries such as Algeria, Morocco, and Tunisia (or their descendants). The United Kingdom has a Jewish community of 292,000. In Eastern Europe, there are anywhere from 350,000 to one million Jews living in the former Soviet Union, but exact figures are difficult to establish. In Germany, the 102,000 Jews registered with the Jewish community are a slowly declining population, despite the immigration of tens of thousands of Jews from the former Soviet Union since the fall of the Berlin Wall. Thousands of Israelis also live in Germany, either permanently or temporarily, for economic reasons.

Question: What is the population of Jews in the United Kingdom?
Ans: 292,000

Here is a question about this article: Pumped-storage hydroelectricity stores energy in the form of water pumped when energy is available from a lower elevation reservoir to a higher elevation one. The energy is recovered when demand is high by releasing the water, with the pump becoming a hydroelectric power generator.
What is the answer to this question: When water is released due to high demand, the pump become swhat?
****
So... a hydroelectric power generator

Article: Although night air defence was causing greater concern before the war, it was not at the forefront of RAF planning. Most of the resources went into planning for daylight fighter defences. The difficulty RAF bombers had navigating in darkness, led the British to believe German bombers would suffer the same problems and would be unable to reach and identify their targets. There was also a mentality in all air forces that, if they could carry out effective operations by day, night missions and their disadvantages could be avoided.

Question: What did the Air Force believe they could avoid if they carried out effective day missions?
Ans:
night missions and their disadvantages
