question:
Passage: The Treaty of Paris stood until 1871, when France was defeated by Prussia in the Franco-Prussian War of 1870–1871. While Prussia and several other German states united to form a powerful German Empire, the Emperor of the French, Napoleon III, was deposed to permit the formation of a Third French Republic. During his reign, Napoleon III, eager for the support of the United Kingdom, had opposed Russia over the Eastern Question. Russian interference in the Ottoman Empire, however, did not in any significant manner threaten the interests of France. Thus, France abandoned its opposition to Russia after the establishment of a republic. Encouraged by the decision of the French, and supported by the German minister Otto von Bismarck, Russia renounced the Black Sea clauses of the treaty agreed to in 1856. As the United Kingdom alone could not enforce the clauses, Russia once again established a fleet in the Black Sea. Question: Between what years did the  Franco-Prussian War take place?
answer:
1870–1871


question:
Passage: Because of the acceptance of miscegenation, Brazil has avoided the binary polarization of society into black and white. In addition, it abolished slavery without a civil war. The bitter and sometimes violent racial tensions that have divided the US are notably absent in Brazil. According to the 2010 census, 6.7% of Brazilians said they were black, compared with 6.2% in 2000, and 43.1% said they were racially mixed, up from 38.5%. In 2010, Elio Ferreira de Araujo, Brazil's minister for racial equality, attributed the increases to growing pride among his country's black and indigenous communities. Question: How do the US and Brazil vary after slavery has ended?
answer:
violent racial tensions that have divided the US are notably absent in Brazil.


question:
Passage: After just 100 hours of ground combat, and with all of Kuwait and much of southern Iraq under coalition control, US President George H. W. Bush ordered a cease-fire and negotiations began resulting in an agreement for cessation of hostilities. Some US politicians were disappointed by this move, believing Bush should have pressed on to Baghdad and removed Hussein from power; there is little doubt that coalition forces could have accomplished this if they had desired. Still, the political ramifications of removing Hussein would have broadened the scope of the conflict greatly, and many coalition nations refused to participate in such an action, believing it would create a power vacuum and destabilize the region. Question: Coalition nations did what with regards to invading Northern Iraq to precipitate the cease fire?
answer:

refused to participate
