Problem: Given the question: Question: "What kind of people liked The Road to Serfdom?" Context: "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." Answer:

The answer is:
those advocating individualism and classical liberalism

Problem: Given the question: Question: "What is the irregularities of the surface smaller than for specular reflection?" Context: "The net quality of a ground reflection depends on the topography of the surface. When the irregularities of the surface are much smaller than the wavelength, we are in the regime of specular reflection, and the receiver sees both the real antenna and an image of the antenna under the ground due to reflection. But if the ground has irregularities not small compared to the wavelength, reflections will not be coherent but shifted by random phases. With shorter wavelengths (higher frequencies), this is generally the case." Answer:
++++++++++++++++++++++++++++++++
The answer is:
wavelength

Problem: Given the question: Question: "When was the second widespread invasion of Red crossbills Loxia curvirostra across England?" Context: "Sometimes circumstances such as a good breeding season followed by a food source failure the following year lead to irruptions in which large numbers of a species move far beyond the normal range. Bohemian waxwings Bombycilla garrulus well show this unpredictable variation in annual numbers, with five major arrivals in Britain during the nineteenth century, but 18 between the years 1937 and 2000. Red crossbills Loxia curvirostra too are irruptive, with widespread invasions across England noted in 1251, 1593, 1757, and 1791." Answer:
++++++++++++++++++++++++++++++++
The answer is:
1593
