Here is a question about this article: Korea was ruled by Japan from 1910 until the closing days of World War II. In August 1945, the Soviet Union declared war on Japan and—by agreement with the United States—occupied Korea north of the 38th parallel. U.S. forces subsequently occupied the south and Japan surrendered. By 1948, two separate governments had been set up. Both governments claimed to be the legitimate government of Korea, and neither side accepted the border as permanent. The conflict escalated into open warfare when North Korean forces—supported by the Soviet Union and China—invaded South Korea on 25 June 1950. On that day, the United Nations Security Council recognized this North Korean act as invasion and called for an immediate ceasefire. On 27 June, the Security Council adopted S/RES/83: Complaint of aggression upon the Republic of Korea and decided the formation and dispatch of the UN Forces in Korea. Twenty-one countries of the United Nations eventually contributed to the defense of South Korea, with the United States providing 88% of the UN's military personnel.

Here is a question about this article: 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.
What is the answer to this question: How many institutions of higher education did Russia possess in 1974?

So...
475
