PROBLEM: Passage: The February Revolution had toppled Tsar Nicolas II of Russia, and replaced his government with the Russian Provisional Government. However, the provisional government was weak and riven by internal dissension. It continued to wage World War I, which became increasingly unpopular. A nationwide crisis developed in Russia, affecting social, economic, and political relations. Disorder in industry and transport had intensified, and difficulties in obtaining provisions had increased. Gross industrial production in 1917 had decreased by over 36% from what it had been in 1914. In the autumn, as much as 50% of all enterprises were closed down in the Urals, the Donbas, and other industrial centers, leading to mass unemployment. At the same time, the cost of living increased sharply. Real wages fell about 50% from what they had been in 1913. Russia's national debt in October 1917 had risen to 50 billion rubles. Of this, debts to foreign governments constituted more than 11 billion rubles. The country faced the threat of financial bankruptcy.
Question: When did the February Revolution occur?

SOLUTION: date

PROBLEM: Passage: Joaquín de Montserrat was named viceroy of New Spain early in 1760. The transfer of power was made September 19, 1760 in Otumba, and his formal entry into Mexico City was October 6, 1760. Among his immediate and most important concerns was the organization of a true colonial army. As he passed through Puebla he reviewed a battalion of militia formed of Negroes and Mulattoes. Their arms were very irregular, and the new viceroy made a formal request to Spain for new rifles to arm them. In 1761 there was an epidemic of smallpox that principally attacked the Indians. Estimates were 14,600 dead in Mexico City and up to 80,000 in Puebla. The government nearly emptied its coffers  to provide what palliative assistance was possible. Viceroy Montserrat took economy measures, ordered the collection of back taxes, and prohibited hoarding of foodstuffs and merchandise. On November 20, 1761, Mayas under Jacinto Canek rose in rebellion in Cisteil, Yucatan. Canek was captured, and on December 14, 1761 he was tortured and quartered in the plaza of Valladolid. Other disasters during Montserrat's term of office included a major flood in Guanajuato that paralyzed the operation of the silver mines , and another epidemic  that caused many deaths . He also had to send military assistance to Sonora, where a revolt of Pimas and Seris had broken out against their maltreatment by the Spanish colonists. The rebels had killed the garrisons of two presidios and the governor before escaping to the mountains, where they were finally subdued.
