Problem: However, William Woodthorpe Tarn, between World War I and World War II and the heyday of the League of Nations, focused on the issues of racial and cultural confrontation and the nature of colonial rule. Michael Rostovtzeff, who fled the Russian Revolution, concentrated predominantly on the rise of the capitalist bourgeoisie in areas of Greek rule. Arnaldo Momigliano, an Italian Jew who wrote before and after the Second World War, studied the problem of mutual understanding between races in the conquered areas. Moses Hadas portrayed an optimistic picture of synthesis of culture from the perspective of the 1950s, while Frank William Walbank in the 1960s and 1970s had a materialistic approach to the Hellenistic period, focusing mainly on class relations. Recently, however, papyrologist C. Preaux has concentrated predominantly on the economic system, interactions between kings and cities and provides a generally pessimistic view on the period. Peter Green, on the other hand, writes from the point of view of late 20th century liberalism, his focus being on individualism, the breakdown of convention, experiments and a postmodern disillusionment with all institutions and political processes.
Who studied the problem mutual understanding between races in conquered areas?
The answer is the following: Arnaldo Momigliano

Problem: However, during this period, major figures and artists in the scene began leaning away from underground aesthetics. In the music press, the increasingly esoteric writing of post-punk publications soon began to alienate their readerships; it is estimated that within several years, NME suffered the loss of half its circulation. Writers like Paul Morley began advocating "overground brightness" instead of the experimental sensibilities promoted in early years. Morley's own musical collaboration with engineer Gary Langan and programmer J. J. Jeczalik, the Art of Noise, would attempt to bring sampled and electronic sounds to the pop mainstream. A variety of more pop-oriented groups, including ABC, the Associates, Adam and the Ants and Bow Wow Wow (the latter two managed by former Sex Pistols manager Malcolm McLaren) emerged in tandem with the development of the New Romantic subcultural scene. Emphasizing glamour, fashion, and escapism in distinction to the experimental seriousness of earlier post-punk groups, the club-oriented scene drew some suspicion from denizens of the movement.
What did the Art of Noise hope to accomplish?
The answer is the following:
attempt to bring sampled and electronic sounds to the pop mainstream
