Problem: I know that the answer to the question "What did Hayek call 'that unobtainable book'?" is in "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.". Can you tell me what it is?

Problem: I know that the answer to the question "Where is Popper's ideas criticized?" is in "In 2004, philosopher and psychologist Michel ter Hark (Groningen, The Netherlands) published a book, called Popper, Otto Selz and the rise of evolutionary epistemology, in which he claimed that Popper took some of his ideas from his tutor, the German psychologist Otto Selz. Selz never published his ideas, partly because of the rise of Nazism, which forced him to quit his work in 1933, and the prohibition of referring to Selz' work. Popper, the historian of ideas and his scholarship, is criticised in some academic quarters for his rejection of Plato, Hegel and Marx.". Can you tell me what it is?

Problem: I know that the answer to the question "The Ottomans, like the Russians, had a?" is in "The Russians sent a fleet to Sinop in northern Anatolia. In the Battle of Sinop on 30 November 1853 they destroyed a patrol squadron of Ottoman frigates and corvettes while they were anchored in port. Public opinion in the UK and France was outraged and demanded war. Sinop provided the United Kingdom and France with the casus belli ("cause for war") for declaring war against Russia. On 28 March 1854, after Russia ignored an Anglo-French ultimatum to withdraw from the Danubian Principalities, the UK and France formally declared war.". Can you tell me what it is?
