TASK DEFINITION: In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
PROBLEM: Which of the following did not occur in the 20th century: urbanization, the spread of the Ottoman Empire, or wars?, Context: South Slavic historically formed a dialect continuum, i.e. each dialect has some similarities with the neighboring one, and differences grow with distance. However, migrations from the 16th to 18th centuries resulting from the spread of Ottoman Empire on the Balkans have caused large-scale population displacement that broke the dialect continuum into many geographical pockets. Migrations in the 20th century, primarily caused by urbanization and wars, also contributed to the reduction of dialectal differences.

SOLUTION: spread of Ottoman Empire

PROBLEM: Universal's parent company purchased Universal from whom?, Context: Matsushita provided a cash infusion, but the clash of cultures was too great to overcome, and five years later Matsushita sold an 80% stake in MCA/Universal to Canadian drinks distributor Seagram for $5.7 billion. Seagram sold off its stake in DuPont to fund this expansion into the entertainment industry. Hoping to build an entertainment empire around Universal, Seagram bought PolyGram in 1999 and other entertainment properties, but the fluctuating profits characteristic of Hollywood were no substitute for the reliable income stream gained from the previously held shares in DuPont.

SOLUTION: Matsushita

PROBLEM: What was protested?, Context: Democratic Party candidates were consistently elected to local office, increasing the city's ties to the South and its dominant party. In 1861, Mayor Fernando Wood called on the aldermen to declare independence from Albany and the United States after the South seceded, but his proposal was not acted on. Anger at new military conscription laws during the American Civil War (1861–1865), which spared wealthier men who could afford to pay a $300 (equivalent to $5,766 in 2016) commutation fee to hire a substitute, led to the Draft Riots of 1863, whose most visible participants were ethnic Irish working class. The situation deteriorated into attacks on New York's elite, followed by attacks on black New Yorkers and their property after fierce competition for a decade between Irish immigrants and blacks for work. Rioters burned the Colored Orphan Asylum to the ground, but more than 200 children escaped harm due to efforts of the New York City Police Department, which was mainly made up of Irish immigrants. According to historian James M. McPherson (2001), at least 120 people were killed. In all, eleven black men were lynched over five days, and the riots forced hundreds of blacks to flee the city for Williamsburg, Brooklyn, as well as New Jersey; the black population in Manhattan fell below 10,000 by 1865, which it had last been in 1820. The white working class had established dominance. Violence by longshoremen against black men was especially fierce in the docks area. It was one of the worst incidents of civil unrest in American history.

SOLUTION:
Draft
