Increasing state control over the oil sector, the RCC began a program of nationalization, starting with the expropriation of British Petroleum's share of the British Petroleum-N.B. Hunt Sahir Field in December 1971. In September 1973, it was announced that all foreign oil producers active in Libya were to be nationalized. For Gaddafi, this was an important step towards socialism. It proved an economic success; while gross domestic product had been $3.8 billion in 1969, it had risen to $13.7 billion in 1974, and $24.5 billion in 1979. In turn, the Libyans' standard of life greatly improved over the first decade of Gaddafi's administration, and by 1979 the average per-capita income was at $8,170, up from $40 in 1951; this was above the average of many industrialized countries like Italy and the U.K.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was Libya's per-capita income in 1951?
Ah, so.. $40

The United States joined World War II in December 1941 after the Japanese attack on Pearl Harbor. On the European front, U.S. Army troops formed a significant portion of the forces that captured North Africa and Sicily, and later fought in Italy. On D-Day, June 6, 1944, and in the subsequent liberation of Europe and defeat of Nazi Germany, millions of U.S. Army troops played a central role. In the Pacific War, U.S. Army soldiers participated alongside the United States Marine Corps in capturing the Pacific Islands from Japanese control. Following the Axis surrenders in May (Germany) and August (Japan) of 1945, army troops were deployed to Japan and Germany to occupy the two defeated nations. Two years after World War II, the Army Air Forces separated from the army to become the United States Air Force in September 1947 after decades of attempting to separate. Also, in 1948, the army was desegregated by order of President Harry S. Truman.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who was responsible for the desegregation of the army?
Ah, so.. Harry S. Truman

Science came to play a leading role in Enlightenment discourse and thought. Many Enlightenment writers and thinkers had backgrounds in the sciences and associated scientific advancement with the overthrow of religion and traditional authority in favour of the development of free speech and thought. Scientific progress during the Enlightenment included the discovery of carbon dioxide (fixed air) by the chemist Joseph Black, the argument for deep time by the geologist James Hutton, and the invention of the steam engine by James Watt. The experiments of Lavoisier were used to create the first modern chemical plants in Paris, and the experiments of the Montgolfier Brothers enabled them to launch the first manned flight in a hot-air balloon on 21 November 1783, from the Chateau de la Muette, near the Bois de Boulogne.

Ah, so..
chemist Joseph Black
