Problem: Friedrich Hayek:

Hayek was concerned about the general view in Britain's academia that fascism was a capitalist reaction to socialism and The Road to Serfdom arose from those concerns. It was written between 1940 and 1943. The title was inspired by the French classical liberal thinker Alexis de Tocqueville's writings on the "road to servitude." It was first published in Britain by Routledge in March 1944 and was quite popular, leading Hayek to call it "that unobtainable book," also due in part to wartime paper rationing. When it was published in the United States by the University of Chicago in September of that year, it achieved greater popularity than in Britain. At the arrangement of editor Max Eastman, the American magazine Reader's Digest also published an abridged version in April 1945, enabling The Road to Serfdom to reach a far wider audience than academics. The book is widely popular among those advocating individualism and classical liberalism.

Whose works served as inspiration for the title of Road to Serfdom?
---
A: Alexis de Tocqueville


Problem: Everton F.C.:

Everton were relegated to the Second Division two years later during internal turmoil at the club. However, the club was promoted at the first attempt scoring a record number of goals in the second division. On return to the top flight in 1931–32, Everton wasted no time in reaffirming their status and won a fourth League title at the first opportunity. Everton also won their second FA Cup in 1933 with a 3–0 win against Manchester City in the final. The era ended in 1938–39 with a fifth League title.

What was the score of the final game that resulted in Everton winning its fifth league title?

A: unanswerable


Problem: Guam:

The Northern Mariana Islands had become a Japanese protectorate before the war. It was the Chamorros from the Northern Marianas who were brought to Guam to serve as interpreters and in other capacities for the occupying Japanese force. The Guamanian Chamorros were treated as an occupied enemy by the Japanese military. After the war, this would cause resentment between the Guamanian Chamorros and the Chamorros of the Northern Marianas. Guam's Chamorros believed their northern brethren should have been compassionate towards them, whereas having been occupied for over 30 years, the Northern Mariana Chamorros were loyal to Japan.

Who were the Guamanian Chamorro loyal to?

A: unanswerable


Problem: Railway electrification system:

In the former Soviet Union, electric traction eventually became somewhat more energy-efficient than diesel. Partly due to inefficient generation of electricity in the USSR (only 20.8% thermal efficiency in 1950 vs. 36.2% in 1975), in 1950 diesel traction was about twice as energy efficient as electric traction (in terms of net tonne-km of freight per kg of fuel). But as efficiency of electricity generation (and thus of electric traction) improved, by about 1965 electric railways became more efficient than diesel. After the mid 1970s electrics used about 25% less fuel per ton-km. However diesels were mainly used on single track lines with a fair amount of traffic  so that the lower fuel consumption of electrics may be in part due to better operating conditions on electrified lines (such as double tracking) rather than inherent energy efficiency. Nevertheless, the cost of diesel fuel was about 1.5 times more (per unit of heat energy content) than that of the fuel used in electric power plants (that generated electricity), thus making electric railways even more energy-cost effective.

Due to the inefficient generation of electricity in the US, diesel traction was twice as energy efficient in what year?
