[EX Q]: Passage: By the end of the 12th century, samurai became almost entirely synonymous with bushi, and the word was closely associated with the middle and upper echelons of the warrior class. The samurai were usually associated with a clan and their lord, were trained as officers in military tactics and grand strategy, and they followed a set of rules that later came to be known as the bushido. While the samurai numbered less than 10% of then Japan's population, their teachings can still be found today in both everyday life and in modern Japanese martial arts. Question: What did samurai mean nearly the same thing as?
[EX A]: bushi

[EX Q]: Passage: Energy gives rise to weight when it is trapped in a system with zero momentum, where it can be weighed. It is also equivalent to mass, and this mass is always associated with it. Mass is also equivalent to a certain amount of energy, and likewise always appears associated with it, as described in mass-energy equivalence. The formula E = mc, derived by Albert Einstein (1905) quantifies the relationship between rest-mass and rest-energy within the concept of special relativity. In different theoretical frameworks, similar formulas were derived by J. J. Thomson (1881), Henri Poincare (1900), Friedrich Hasenohrl (1904) and others (see Mass-energy equivalence#History for further information). Question: In what year did Einstein create E = mc2?
[EX A]: 1905

[EX Q]: Passage: 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. Question: How did Japan rise to be a world power during the Meja era?
[EX A]:
modernization
