In the latter half of his career Hayek made a number of contributions to social and political philosophy, which he based on his views on the limits of human knowledge, and the idea of spontaneous order in social institutions. He argues in favour of a society organised around a market order, in which the apparatus of state is employed almost (though not entirely) exclusively to enforce the legal order (consisting of abstract rules, and not particular commands) necessary for a market of free individuals to function. These ideas were informed by a moral philosophy derived from epistemological concerns regarding the inherent limits of human knowledge. Hayek argued that his ideal individualistic, free-market polity would be self-regulating to such a degree that it would be 'a society which does not depend for its functioning on our finding good men for running it'.

What would Hayek's free-market not require in order to function properly?
Answer: good men

In the final days of World War II in Yugoslavia, units of the Partisans were responsible for atrocities after the repatriations of Bleiburg, and accusations of culpability were later raised at the Yugoslav leadership under Tito. At the time, Josip Broz Tito repeatedly issued calls for surrender to the retreating column, offering amnesty and attempting to avoid a disorderly surrender. On 14 May he dispatched a telegram to the supreme headquarters Slovene Partisan Army prohibiting "in the sternest language" the execution of prisoners of war and commanding the transfer of the possible suspects to a military court.

What did Tito offer to the retreating column?
Answer: amnesty

Incandescent bulbs are much less efficient than most other types of electric lighting; incandescent bulbs convert less than 5% of the energy they use into visible light, with standard light bulbs averaging about 2.2%. The remaining energy is converted into heat. The luminous efficacy of a typical incandescent bulb is 16 lumens per watt, compared with 60 lm/W for a compact fluorescent bulb or 150 lm/W for some white LED lamps. Some applications of the incandescent bulb deliberately use the heat generated by the filament. Such applications include incubators, brooding boxes for poultry, heat lights for reptile tanks, infrared heating for industrial heating and drying processes, lava lamps, and the Easy-Bake Oven toy. Incandescent bulbs typically have short lifetimes compared with other types of lighting; around 1,000 hours for home light bulbs versus typically 10,000 hours for compact fluorescents and 30,000 hours for lighting LEDs.

Are incandescent bulbs more or less efficient than most electric lighting?
Answer:
less efficient
