Problem: Architecture:

When modern architecture was first practiced, it was an avant-garde movement with moral, philosophical, and aesthetic underpinnings. Immediately after World War I, pioneering modernist architects sought to develop a completely new style appropriate for a new post-war social and economic order, focused on meeting the needs of the middle and working classes. They rejected the architectural practice of the academic refinement of historical styles which served the rapidly declining aristocratic order. The approach of the Modernist architects was to reduce buildings to pure forms, removing historical references and ornament in favor of functionalist details. Buildings displayed their functional and structural elements, exposing steel beams and concrete surfaces instead of hiding them behind decorative forms.

What kind of movement was modern architecture in the beginning?

A: avant-garde movement


Problem: Similar organizations in other countries followed: The American Anthropological Association in 1902, the Anthropological Society of Madrid (1865), the Anthropological Society of Vienna (1870), the Italian Society of Anthropology and Ethnology (1871), and many others subsequently. The majority of these were evolutionist. One notable exception was the Berlin Society of Anthropology (1869) founded by Rudolph Virchow, known for his vituperative attacks on the evolutionists. Not religious himself, he insisted that Darwin's conclusions lacked empirical foundation.
Vienna created it's society in what year?

Answer: 1870


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Russell's ministry, though Whig, was not favoured by the Queen. She found particularly offensive the Foreign Secretary, Lord Palmerston, who often acted without consulting the Cabinet, the Prime Minister, or the Queen. Victoria complained to Russell that Palmerston sent official dispatches to foreign leaders without her knowledge, but Palmerston was retained in office and continued to act on his own initiative, despite her repeated remonstrances. It was only in 1851 that Palmerston was removed after he announced the British government's approval of President Louis-Napoleon Bonaparte's coup in France without consulting the Prime Minister. The following year, President Bonaparte was declared Emperor Napoleon III, by which time Russell's administration had been replaced by a short-lived minority government led by Lord Derby.
What position did Lord Palmerston hold?
A: Foreign Secretary


Context and question: After a visit to Brasília, the French writer Simone de Beauvoir complained that all of its superquadras exuded "the same air of elegant monotony," and other observers have equated the city's large open lawns, plazas, and fields to wastelands. As the city has matured, some of these have gained adornments, and many have been improved by landscaping, giving some observers a sense of "humanized" spaciousness. Although not fully accomplished, the "Brasília utopia" has produced a city of relatively high quality of life, in which the citizens live in forested areas with sporting and leisure structure (the superquadras) flanked by small commercial areas, bookstores and cafes; the city is famous for its cuisine and efficiency of transit.
What did the citizens complain after visiting Brasilia?
Answer: unanswerable

QUES: The vast majority of devices containing LEDs are "safe under all conditions of normal use", and so are classified as "Class 1 LED product"/"LED Klasse 1". At present, only a few LEDs—extremely bright LEDs that also have a tightly focused viewing angle of 8° or less—could, in theory, cause temporary blindness, and so are classified as "Class 2". The opinion of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) of 2010, on the health issues concerning LEDs, suggested banning public use of lamps which were in the moderate Risk Group 2, especially those with a high blue component in places frequented by children. In general, laser safety regulations—and the "Class 1", "Class 2", etc. system—also apply to LEDs.

 What does being a Class 2 LED product mean?
