Problem: Please answer a question about the following article about Paris:
Bal-musette is a style of French music and dance that first became popular in Paris in the 1870s and 1880s; by 1880 Paris had some 150 dance halls in the working-class neighbourhoods of the city. Patrons danced the bourrée to the accompaniment of the cabrette (a bellows-blown bagpipe locally called a "musette") and often the vielle à roue (hurdy-gurdy) in the cafés and bars of the city. Parisian and Italian musicians who played the accordion adopted the style and established themselves in Auvergnat bars especially in the 19th arrondissement, and the romantic sounds of the accordion has since become one of the musical icons of the city. Paris became a major centre for jazz and still attracts jazz musicians from all around the world to its clubs and cafés.
in 1880, how many dance halls were in Paris?
A: 150


Question: Read this and answer the question

Russia feared losing Russian America without compensation in some future conflict, especially to the British. While Alaska attracted little interest at the time, the population of nearby British Columbia started to increase rapidly a few years after hostilities ended. Therefore, the Russian emperor, Alexander II, decided to sell Alaska. In 1859 the Russians offered to sell the territory to the United States, hoping that its presence in the region would offset the plans of Russia's greatest regional rival, the United Kingdom.

What did the Russians fear losing without compensation?
Answer: British Columbia


Problem: C trigraphs were created to solve this problem for ANSI C, although their late introduction and inconsistent implementation in compilers limited their use. Many programmers kept their computers on US-ASCII, so plain-text in Swedish, German etc. (for example, in e-mail or Usenet) contained "{, }" and similar variants in the middle of words, something those programmers got used to. For example, a Swedish programmer mailing another programmer asking if they should go for lunch, could get "N{ jag har sm|rg}sar." as the answer, which should be "Nä jag har smörgåsar." meaning "No I've got sandwiches."
What did many programmers keep their computers on?
The answer is the following: US-ASCII


Solar energy may be used in a water stabilisation pond to treat waste water without chemicals or electricity. A further environmental advantage is that algae grow in such ponds and consume carbon dioxide in photosynthesis, although algae may produce toxic chemicals that make the water unusable.
For what reason would solar energy be used in a water stabilisation pond?
to treat waste water without chemicals or electricity


Input: Annelid
Nearly all polychaetes have parapodia that function as limbs, while other major annelid groups lack them. Parapodia are unjointed paired extensions of the body wall, and their muscles are derived from the circular muscles of the body. They are often supported internally by one or more large, thick chetae. The parapodia of burrowing and tube-dwelling polychaetes are often just ridges whose tips bear hooked chetae. In active crawlers and swimmers the parapodia are often divided into large upper and lower paddles on a very short trunk, and the paddles are generally fringed with chetae and sometimes with cirri (fused bundles of cilia) and gills.

What kind of parapodia do burrowing annelids often have?
Output: ridges whose tips bear hooked chetae


Problem: Please answer a question about the following article about MP3:
When performing lossy audio encoding, such as creating an MP3 file, there is a trade-off between the amount of space used and the sound quality of the result. Typically, the creator is allowed to set a bit rate, which specifies how many kilobits the file may use per second of audio. The higher the bit rate, the larger the compressed file will be, and, generally, the closer it will sound to the original file.
What would an example of lossy audio encoding be?
A:
creating an MP3 file
