PROBLEM: Though much of Enlightenment political thought was dominated by social contract theorists, both David Hume and Adam Ferguson criticized this camp. Hume's essay Of the Original Contract argues that governments derived from consent are rarely seen, and civil government is grounded in a ruler's habitual authority and force. It is precisely because of the ruler's authority over-and-against the subject, that the subject tacitly consents; Hume says that the subjects would "never imagine that their consent made him sovereign", rather the authority did so. Similarly, Ferguson did not believe citizens built the state, rather polities grew out of social development. In his 1767 An Essay on the History of Civil Society, Ferguson uses the four stages of progress, a theory that was very popular in Scotland at the time, to explain how humans advance from a hunting and gathering society to a commercial and civil society without "signing" a social contract.

SOLUTION: In what work did Ferguson explain how humans advanced from a hunting and gathering society to a commercial and civil society without "signing" a social contract?

PROBLEM: Tito became increasingly ill over the course of 1979. During this time Vila Srna was built for his use near Morović in the event of his recovery. On 7 January and again on 11 January 1980, Tito was admitted to the Medical Centre in Ljubljana, the capital city of the SR Slovenia, with circulation problems in his legs. His left leg was amputated soon afterward due to arterial blockages and he died of gangrene at the Medical Centre Ljubljana on 4 May 1980 at 15:05, three days short of his 88th birthday. His funeral drew many world statesmen. Based on the number of attending politicians and state delegations, at the time it was the largest state funeral in history; this concentration of dignitaries would be unmatched until the funeral of Pope John Paul II in 2005 and the memorial service of Nelson Mandela in 2013. Those who attended included four kings, 31 presidents, six princes, 22 prime ministers and 47 ministers of foreign affairs. They came from both sides of the Cold War, from 128 different countries out of 154 UN members at the time.

SOLUTION: During what year did Tito become increasingly ill?
