Problem: Alaska:

On March 27, 1964, the massive Good Friday earthquake killed 133 people and destroyed several villages and portions of large coastal communities, mainly by the resultant tsunamis and landslides. It was the second-most-powerful earthquake in the recorded history of the world, with a moment magnitude of 9.2. It was over one thousand times more powerful than the 1989 San Francisco earthquake. The time of day (5:36 pm), time of year and location of the epicenter were all cited as factors in potentially sparing thousands of lives, particularly in Anchorage.

How did the Good Friday earthquake compare to other documented earthquakes in the world?

A: second-most-powerful earthquake in the recorded history of the world

Problem: Portugal:

Portugal's national energy transmission company, Redes Energeticas Nacionais (REN), uses sophisticated modeling to predict weather, especially wind patterns, and computer programs to calculate energy from the various renewable-energy plants. Before the solar/wind revolution, Portugal had generated electricity from hydropower plants on its rivers for decades. New programs combine wind and water: wind-driven turbines pump water uphill at night, the most blustery period; then the water flows downhill by day, generating electricity, when consumer demand is highest. Portugal's distribution system is also now a two-way street. Instead of just delivering electricity, it draws electricity from even the smallest generators, like rooftop solar panels. The government aggressively encouraged such contributions by setting a premium price for those who buy rooftop-generated solar electricity.

How did the Portuguese government encourage rooftop solar panels?

A: setting a premium price

Problem: Charleston, South Carolina:

Violent incidents occurred throughout the Piedmont of the state as white insurgents struggled to maintain white supremacy in the face of social changes after the war and granting of citizenship to freedmen by federal constitutional amendments. After former Confederates were allowed to vote again, election campaigns from 1872 on were marked by violent intimidation of blacks and Republicans by white Democratic paramilitary groups, known as the Red Shirts. Violent incidents took place in Charleston on King Street in September 6 and in nearby Cainhoy on October 15, both in association with political meetings before the 1876 election. The Cainhoy incident was the only one statewide in which more whites were killed than blacks. The Red Shirts were instrumental in suppressing the black Republican vote in some areas in 1876 and narrowly electing Wade Hampton as governor, and taking back control of the state legislature. Another riot occurred in Charleston the day after the election, when a prominent Republican leader was mistakenly reported killed.

The Cainhoy Incident occurred on what day?

A: October 15

Problem: Middle Ages:

Strong, royalty-based nation states rose throughout Europe in the Late Middle Ages, particularly in England, France, and the Christian kingdoms of the Iberian Peninsula: Aragon, Castile, and Portugal. The long conflicts of the period strengthened royal control over their kingdoms and were extremely hard on the peasantry. Kings profited from warfare that extended royal legislation and increased the lands they directly controlled. Paying for the wars required that methods of taxation become more effective and efficient, and the rate of taxation often increased. The requirement to obtain the consent of taxpayers allowed representative bodies such as the English Parliament and the French Estates General to gain power and authority.

What English representative body provided consent for royal taxation?

A:
Parliament
