Q: The minimum wage, public-sector wages, and old-age pensions are routinely raised twice a year to ensure that base income is not eroded by inflation. Although no statistics are published on average wages in Uzbekistan, pensions as a proxy for the average wage increased significantly between 1995 and 2006, both in real terms and in U.S. dollars. The monthly old-age pension increased in real (CPI-adjusted) sums by almost a factor of 5 between 1995 and 2006. The monthly pension in U.S. dollars was around $20$25 until 2000, then dropped to $15$20 between 2001 and 2004, and now is $64. The minimum wage was raised to $34.31 in November 2011. Assuming that the average wages in the country are at a level of 3-4 times the monthly pension, we estimate the wages in 2006 at $100$250 per month, or $3$8 per day.
How many years did it take for pensions to increase by a factor of almost 5?

A: 11

Q: In 1900, the Mexican population was 13.6 million. During the period of economic prosperity that was dubbed by economists as the "Mexican Miracle", the government invested in efficient social programs that reduced the infant mortality rate and increased life expectancy. These measures jointly led to an intense demographic increase between 1930 and 1980. The populations annual growth rate has been reduced from a 3.5% peak in 1965 to 0.99% in 2005. While Mexico is now transitioning to the third phase of demographic transition, close to 50% of the population in 2009 was 25 years old or younger. Fertility rates have also decreased from 5.7 children per woman in 1976 to 2.2 in 2006. The average annual population growth rate of the capital, the Mexico City, was the first in the country at 0.2%. The state with the lowest population growth rate over the same period was Michoacan (-0.1%), whereas the states with the highest population growth rates were Quintana Roo (4.7%) and Baja California Sur (3.4%), both of which are two of the least populous states and the last to be admitted to the Union in the 1970s. The average annual net migration rate of the Federal District over the same period was negative and the lowest of all political divisions of Mexico, whereas the states with the highest net migration rate were Quintana Roo (2.7), Baja California (1.8) and Baja California Sur (1.6). While the national annual growth rate was still positive (1.0%) in the early years of the 2000s, the national net migration rate was negative (-4.75/1000 inhabitants), given the former strong flow of immigrants to the United States; an estimated 5.3 million undocumented Mexicans lived in the United States in 2004 and 18.2 million American citizens in the 2000 Census declared having Mexican ancestry. However, as of recent years in the 2010s, the net migration rate reached 0, given the strong economy of Mexico and a weakening American economy, causing many of its former residents to return. However, Mexico is the second country in the total number of immigrants to the United States from 1830 to 2000, after Germany.
How many points has the fertility rates decreased from 1976 to 2006?

A: 3.5

Q: In 1344, Momchil, the independent Bulgarian ruler of the Rhodope and Aegean regions, whose army grew to 2,000 men, took an important role in the Byzantine civil war. While at first he supported John Kantakouzenos, from the spring of 1344 Momchil reneged, provoked by the aggression of the Ottoman allies. In June he defeated the Ottoman fleet near the Portogalos bay. According to sources, at night the Bulgarian ruler sent boats to burn the anchored Ottoman ships and soon after he defeated the army of Kantakouzenos at Mosynopolis. Probably the first local ruler to become aware of the impending Ottoman threat, Momchil unsuccessfully pleaded with the emperors of Bulgaria and Byzantium for help. Even though his troops continued the resistance in the Eastern Rhodopes, in May 1345 the Turks led by Umur Beg marched from Asia Minor and devastated Bulgarian territories driving away people and livestock. Soon after, on 7 July 1345, Ottoman forces under Umur Beg defeated Momchil's army in the battle of Peritor near his capital Xanthi. Sources attest that the independent ruler perished in the battle without leaving asuccessor, and with little political will or leadership left to counter the Ottoman invasion.
