Article: The May Fourth Movement helped to rekindle the then-fading cause of republican revolution. In 1917 Sun Yat-sen had become commander-in-chief of a rival military government in Guangzhou in collaboration with southern warlords. Sun's efforts to obtain aid from the Western democracies were ignored, however, and in 1920 he turned to the Soviet Union, which had recently achieved its own revolution. The Soviets sought to befriend the Chinese revolutionists by offering scathing attacks on Western imperialism. But for political expediency, the Soviet leadership initiated a dual policy of support for both Sun and the newly established Chinese Communist Party (CCP).

Question: What did Sun Yat-Sen hope to get from western democracies?
Ans: aid


Here is a question about this article: In Canada, the Royal Newfoundland Constabulary was founded in 1729, making it the first police force in present-day Canada. It was followed in 1834 by the Toronto Police, and in 1838 by police forces in Montreal and Quebec City. A national force, the Dominion Police, was founded in 1868. Initially the Dominion Police provided security for parliament, but its responsibilities quickly grew. The famous Royal Northwest Mounted Police was founded in 1873. The merger of these two police forces in 1920 formed the world-famous Royal Canadian Mounted Police.
What is the answer to this question: What was Canada's first police force?
****
So... Royal Newfoundland Constabulary

During his years in Paris he was to become acquainted with, among many others, Hector Berlioz, Franz Liszt, Ferdinand Hiller, Heinrich Heine, Eugène Delacroix, and Alfred de Vigny. Chopin was also acquainted with the poet Adam Mickiewicz, principal of the Polish Literary Society, some of whose verses he set as songs.
Who was the principal of the Polish Literary Society that Frédéric became acquainted with?
****
The answer: Adam Mickiewicz


Problem: Please answer a question about the following article about Switzerland:
Between two thirds and three quarters of the population live in urban areas. Switzerland has gone from a largely rural country to an urban one in just 70 years. Since 1935 urban development has claimed as much of the Swiss landscape as it did during the previous 2,000 years. This urban sprawl does not only affect the plateau but also the Jura and the Alpine foothills and there are growing concerns about land use. However, from the beginning of the 21st century, the population growth in urban areas is higher than in the countryside.
From the beginning of the 21st century, how does the population growth in urban areas compare to the countryside?
A: higher

The most popular term in English-speaking Canada used for a drinking establishment was "tavern", until the 1970s when the term "bar" became widespread as in the United States. In the 1800s the term used was "public house" as in England but "pub culture" did not spread to Canada. A fake "English looking" pub trend started in the 1990s, built into existing storefronts, like regular bars. Most universities in Canada have campus pubs which are central to student life, as it would be bad form just to serve alcohol to students without providing some type of basic food. Often these pubs are run by the student's union. The gastropub concept has caught on, as traditional British influences are to be found in many Canadian dishes. There are now pubs in the large cities of Canada that cater to anyone interested in a "pub" type drinking environment.[citation needed]

In the 19th century, what term was used in English-speaking Canada to describe a drinking establishment?
Answer: public house


Infrared vibrational spectroscopy (see also near-infrared spectroscopy) is a technique that can be used to identify molecules by analysis of their constituent bonds. Each chemical bond in a molecule vibrates at a frequency characteristic of that bond. A group of atoms in a molecule (e.g., CH2) may have multiple modes of oscillation caused by the stretching and bending motions of the group as a whole. If an oscillation leads to a change in dipole in the molecule then it will absorb a photon that has the same frequency. The vibrational frequencies of most molecules correspond to the frequencies of infrared light. Typically, the technique is used to study organic compounds using light radiation from 4000–400 cm−1, the mid-infrared. A spectrum of all the frequencies of absorption in a sample is recorded. This can be used to gain information about the sample composition in terms of chemical groups present and also its purity (for example, a wet sample will show a broad O-H absorption around 3200 cm−1).
What do the vibrational frequencies of molecules usually correspond to?

the frequencies of infrared light
