Problem: In the late 1970s many arterial roads were redesigned as ejes viales; high-volume one-way roads that cross, in theory, Mexico City proper from side to side. The eje vial network is based on a quasi-Cartesian grid, with the ejes themselves being called Eje 1 Poniente, Eje Central, and Eje 1 Oriente, for example, for the north-south roads, and Eje 2 Sur and Eje 3 Norte, for example, for east-west roads. Ring roads are the Circuito Interior (inner ring), Anillo Periferico; the Circuito Exterior Mexiquense ("State of Mexico outer loop") toll road skirting the northeastern and eastern edges of the metropolitan area, the Chamapa-La Venta toll road skirting the northwestern edge, and the Arco Norte completely bypassing the metropolitan area in an arc from northwest (Atlacomulco) to north (Tula, Hidalgo) to east (Puebla). A second level (where tolls are charged) of the Periferico, colloquially called the segundo piso ("second floor"), was officially opened in 2012, with sections still being completed. The Viaducto Miguel Aleman crosses the city east-west from Observatorio to the airport. In 2013 the Supervia Poniente opened, a toll road linking the new Santa Fe business district with southwestern Mexico City.
When were these second level roads opened?
The answer is the following: 2012

Problem: In the 2000s, more Venezuelans opposing the economic and political policies of president Hugo Chavez migrated to the United States (mostly to Florida, but New York City and Houston are other destinations). The largest concentration of Venezuelans in the United States is in South Florida, especially the suburbs of Doral and Weston. Other main states with Venezuelan American populations are, according to the 1990 census, New York, California, Texas (adding their existing Hispanic populations), New Jersey, Massachusetts and Maryland. Some of the urban areas with a high Venezuelan community include Miami, New York City, Los Angeles, and Washington, D.C.
What areas of America did the Venezuelans settle in?
The answer is the following: mostly to Florida, but New York City and Houston are other destinations). The largest concentration of Venezuelans in the United States is in South Florida

Problem: The doctrines of the Assumption or Dormition of Mary relate to her death and bodily assumption to Heaven. The Roman Catholic Church has dogmaically defined the doctrine of the Assumption, which was done in 1950 by Pope Pius XII in Munificentissimus Deus. Whether the Virgin Mary died or not is not defined dogmatically, however, although a reference to the death of Mary are made in Munificentissimus Deus. In the Eastern Orthodox Church, the Assumption of the Virgin Mary is believed, and celebrated with her Dormition, where they believe she died.
In which papal document was the dogma of the Assumption defined?
The answer is the following: Munificentissimus Deus

Problem: French historians traditionally place the Enlightenment between 1715, the year that Louis XIV died, and 1789, the beginning of the French Revolution. Some recent historians begin the period in the 1620s, with the start of the scientific revolution. The Philosophes, the French term for the philosophers of the period, widely circulated their ideas through meetings at scientific academies, Masonic lodges, literary salons and coffee houses, and through printed books and pamphlets. The ideas of the Enlightenment undermined the authority of the monarchy and the church, and paved the way for the revolutions of the 18th and 19th centuries. A variety of 19th-century movements, including liberalism and neo-classicism, trace their intellectual heritage back to the Enlightenment.
What year did the Enlightenment begin according to French historians?
The answer is the following:
1715
