[EX Q]: How was access gained to Alaska, Context: The specifics of Paleo-Indian migration to and throughout the Americas, including the exact dates and routes traveled, provide the subject of ongoing research and discussion. According to archaeological and genetic evidence, North and South America were the last continents in the world with human habitation. During the Wisconsin glaciation, 5017,000 years ago, falling sea levels allowed people to move across the land bridge of Beringia that joined Siberia to north west North America (Alaska). Alaska was a glacial refugia because it had low snowfall, allowing a small population to exist. The Laurentide Ice Sheet covered most of North America, blocking nomadic inhabitants and confining them to Alaska (East Beringia) for thousands of years.
[EX A]: the land bridge

[EX Q]: How vain was Rousseau?, Context: In November 1790, Francois-Louis-Thibault de Menonville, a member of the National Assembly of France, wrote to Burke, praising Reflections and requesting more "very refreshing mental food" that he could publish. This Burke did in April 1791 when he published A Letter to a Member of the National Assembly. Burke called for external forces to reverse the revolution and included an attack on the late French philosopher Jean-Jacques Rousseau, as being the subject of a personality cult that had developed in revolutionary France. Although Burke conceded that Rousseau sometimes showed "a considerable insight into human nature" he mostly was critical. Although he did not meet Rousseau on his visit to Britain in 17667 Burke was a friend of David Hume, with whom Rousseau had stayed. Burke said Rousseau "entertained no principle either to influence of his heart, or to guide his understandingbut vanity"which he "was possessed to a degree little short of madness". He also cited Rousseau's Confessions as evidence that Rousseau had a life of "obscure and vulgar vices" that was not "chequered, or spotted here and there, with virtues, or even distinguished by a single good action". Burke contrasted Rousseau's theory of universal benevolence and his having sent his children to a foundling hospital: "a lover of his kind, but a hater of his kindred".
[EX A]: possessed to a degree little short of madness

[EX Q]: What people played a role in the Japanese military prior to modernization?, Context: Around the end of the 19th century and into the 20th century, the Meiji era was marked by the reign of the Meiji Emperor. During this time, Japan started its modernization and rose to world power status. This era name means "Enlightened Rule". In Japan, the Meiji Restoration started in the 1860s, marking the rapid modernization by the Japanese themselves along European lines. Much research has focused on the issues of discontinuity versus continuity with the previous Tokugawa Period. In the 1960s younger Japanese scholars led by Irokawa Daikichi, reacted against the bureaucratic superstate, and began searching for the historic role of the common people . They avoided the elite, and focused not on political events but on social forces and attitudes. They rejected both Marxism and modernization theory as alien and confining. They stressed the importance of popular energies in the development of modern Japan. They enlarged history by using the methods of social history. It was not until the beginning of the Meiji Era that the Japanese government began taking modernization seriously. Japan expanded its military production base by opening arsenals in various locations. The hyobusho (war office) was replaced with a War Department and a Naval Department. The samurai class suffered great disappointment the following years.
