[Q]: Question: How many people lived in Milan when Diocletian restored political stability after the Crisis of the Third Century? Passage:During the Crisis of the Third Century the Roman Empire nearly collapsed under the combined pressures of invasions, military anarchy and civil wars, and hyperinflation. In 284, emperor Diocletian restored political stability. He carried out thorough administrative reforms to maintain order. He created the so-called Tetrarchy whereby the empire was ruled by two senior emperors called Augusti and two junior vice-emperors called Caesars. He decreased the size of the Roman provinces by doubling their number to reduce the power of the provincial governors. He grouped the provinces into several dioceses (Latin: diocesis) and put them under the supervision of the imperial vicarius (vice, deputy), who was the head of the diocese. During the Crisis of the Third Century the importance of Rome declined because the city was far from the troubled frontiers. Diocletian and his colleagues usually resided in four imperial seats. The Augusti, Diocletian and Maximian, who were responsible for the East and West respectively, established themselves at Nicomedia, in north-western Anatolia (closer to the Persian frontier in the east) and Milan, in northern Italy (closer to the European frontiers) respectively. The seats of the Caesars were Augusta Treverorum (on the River Rhine frontier) for Constantius Chlorus and Sirmium (on the River Danube frontier) for Galerius who also resided at Thessaloniki.

[Q]: Question: Comparing the places Naipaul visited while writing his book, what is the difference in population between the two? Passage:Black & White is a non-fiction book written by Shiva Naipaul and published by Hamish Hamilton in the U.K. in 1980. It was published with the title Journey to Nowhere: A New World Tragedy in the U.S. The book is based on Naipaul's trip to Guyana in the aftermath of the Jonestown Massacre, and his subsequent trip to the United States, in which he explored links between the People's Temple and other groups and individuals. Naipaul attempted to connect Rev. Jim Jones, founder of the People's Temple, with disparate parts of California's counterculture, and Guyanese and other Third World governments and the revolutionary ideologies which supported them. Naipaul was highly critical of these and other movements, including black theology, the nascent New Age movement and EST, in as much as they helped, in his analysis, to create fertile ground for the People's Temple to flourish on the two continents. The book's US paperback cover tagline reads "How American ideas and ideologies led to the mass suicide of 900 people in Jonestown, Guyana."
 Links: a. Guyana b. Jonestown c. Liberation movement d. Shiva Naipaul
