Q: I know that the answer to the question "In what country were there nearly 24 million students in the 1970s?" is in "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.". Can you tell me what it is?

Q: I know that the answer to the question "If someone is talking about it, what words would they use to reference it?" is in "26 March 1991 is the day that marks the clash between military soldiers and peaceful demonstrating students which climaxed in the massacre of dozens under the orders of then President Moussa Traoré. He and three associates were later tried and convicted and received the death sentence for their part in the decision-making of that day. Nowadays, the day is a national holiday in order to remember the tragic events and the people that were killed.[unreliable source?] The coup is remembered as Mali's March Revolution of 1991.".

Q: I know that the answer to the question "Who goes to war in the air force?" is in "Daniel L. Magruder, Jr defines USAF culture as a combination of the rigorous application of advanced technology, individualism and progressive airpower theory. Major General Charles J. Dunlap, Jr. adds that the U.S. Air Force's culture also includes an egalitarianism bred from officers perceiving themselves as their service's principal "warriors" working with small groups of enlisted airmen either as the service crew or the onboard crew of their aircraft. Air Force officers have never felt they needed the formal social "distance" from their enlisted force that is common in the other U.S. armed services. Although the paradigm is changing, for most of its history, the Air Force, completely unlike its sister services, has been an organization in which mostly its officers fought, not its enlisted force, the latter being primarily a rear echelon support force. When the enlisted force did go into harm's way, such as members of multi-crewed aircraft, the close comradeship of shared risk in tight quarters created traditions that shaped a somewhat different kind of officer/enlisted relationship than exists elsewhere in the military.". Can you tell me what it is?
A: officers
