Problem: Please answer a question about the following article about Nutrition:
In 1816, Francois Magendie discovered that dogs fed only carbohydrates (sugar), fat (olive oil), and water died evidently of starvation, but dogs also fed protein survived, identifying protein as an essential dietary component. William Prout in 1827 was the first person to divide foods into carbohydrates, fat, and protein. During the 19th century, Jean-Baptiste Dumas and Justus von Liebig quarrelled over their shared belief that animals get their protein directly from plants (animal and plant protein are the same and that humans do not create organic compounds). With a reputation as the leading organic chemist of his day but with no credentials in animal physiology, Liebig grew rich making food extracts like beef bouillon and infant formula that were later found to be of questionable nutritious value. In the 1860s, Claude Bernard discovered that body fat can be synthesized from carbohydrate and protein, showing that the energy in blood glucose can be stored as fat or as glycogen.
Who did Justus von Liebig argue with over the belief that animals get protein from plants?
A: Jean-Baptiste Dumas
Problem: Please answer a question about the following article about Russian Soviet Federative Socialist Republic:
The economy of Russia became heavily industrialized, accounting for about two-thirds of the electricity produced in the USSR. It was, by 1961, the third largest producer of petroleum due to new discoveries in the Volga-Urals region and Siberia, trailing only the United States and Saudi Arabia. In 1974, there were 475 institutes of higher education in the republic providing education in 47 languages to some 23,941,000 students. A network of territorially-organized public-health services provided health care. After 1985, the restructuring policies of the Gorbachev administration relatively liberalised the economy, which had become stagnant since the late 1970s, with the introduction of non-state owned enterprises such as cooperatives. The effects of market policies led to the failure of many enterprises and total instability by 1990.
How many institutions of higher education did Russia possess in 1974?
A:
475
