Problem: Please answer a question about the following article about Frederic Chopin:
The two became friends, and for many years lived in close proximity in Paris, Chopin at 38 Rue de la Chaussee-d'Antin, and Liszt at the Hotel de France on the Rue Lafitte, a few blocks away. They performed together on seven occasions between 1833 and 1841. The first, on 2 April 1833, was at a benefit concert organized by Hector Berlioz for his bankrupt Shakespearean actress wife Harriet Smithson, during which they played George Onslow's Sonata in F minor for piano duet. Later joint appearances included a benefit concert for the Benevolent Association of Polish Ladies in Paris. Their last appearance together in public was for a charity concert conducted for the Beethoven Memorial in Bonn, held at the Salle Pleyel and the Paris Conservatory on 25 and 26 April 1841.
What address did Frederic live at during his stay in Paris?
A: 38 Rue de la Chaussee-d'Antin
Problem: Please answer a question about the following article about Marshall Islands:
Following capture and occupation by the United States during World War II, the Marshall Islands, along with several other island groups located in Micronesia, passed formally to the United States under United Nations auspices in 1947 as part of the Trust Territory of the Pacific Islands established pursuant to Security Council Resolution 21.
What is the name of the broader region that the Marshall Islands are a part of?
A: Micronesia
Problem: Please answer a question about the following article about Capacitor:
Most types of capacitor include a dielectric spacer, which increases their capacitance. These dielectrics are most often insulators. However, low capacitance devices are available with a vacuum between their plates, which allows extremely high voltage operation and low losses. Variable capacitors with their plates open to the atmosphere were commonly used in radio tuning circuits. Later designs use polymer foil dielectric between the moving and stationary plates, with no significant air space between them.
What did the later designs of capacitors used in radio tuning circuits no longer have?
A: no significant air space
Problem: Please answer a question about the following article about History of science:
Ibn Khaldun can be regarded as the earliest scientific systematic sociologist. The modern sociology, emerged in the early 19th century as the academic response to the modernization of the world. Among many early sociologists (e.g., Emile Durkheim), the aim of sociology was in structuralism, understanding the cohesion of social groups, and developing an "antidote" to social disintegration. Max Weber was concerned with the modernization of society through the concept of rationalization, which he believed would trap individuals in an "iron cage" of rational thought. Some sociologists, including Georg Simmel and W. E. B. Du Bois, utilized more microsociological, qualitative analyses. This microlevel approach played an important role in American sociology, with the theories of George Herbert Mead and his student Herbert Blumer resulting in the creation of the symbolic interactionism approach to sociology.
When did modern sociology surface?
A:
early 19th century
