Problem: Mandolin:

These styles generally have either two f-shaped soundholes like a violin (F-5 and A-5), or an oval sound hole (F-4 and A-4 and lower models) directly under the strings. Much variation exists between makers working from these archetypes, and other variants have become increasingly common. Generally, in the United States, Gibson F-hole F-5 mandolins and mandolins influenced by that design are strongly associated with bluegrass, while the A-style is associated other types of music, although it too is most often used for and associated with bluegrass. The F-5's more complicated woodwork also translates into a more expensive instrument.

 Why is the F-5 mandolin less expensive?

Problem: Dissolution of the Soviet Union:

Thousands of Muscovites came out to defend the White House (the Russian Federation's parliament and Yeltsin's office), the symbolic seat of Russian sovereignty at the time. The organizers tried but ultimately failed to arrest Yeltsin, who rallied opposition to the coup with speech-making atop a tank. The special forces dispatched by the coup leaders took up positions near the White House, but members refused to storm the barricaded building. The coup leaders also neglected to jam foreign news broadcasts, so many Muscovites watched it unfold live on CNN. Even the isolated Gorbachev was able to stay abreast of developments by tuning into BBC World Service on a small transistor radio.

Where was Yeltsin during the coup?

A: atop a tank


Problem: Estonia:

Estonia lies on the eastern shores of the Baltic Sea immediately across the Gulf of Finland from Finland on the level northwestern part of the rising East European platform between 57.3° and 59.5° N and 21.5° and 28.1° E. Average elevation reaches only 50 metres (164 ft) and the country's highest point is the Suur Munamägi in the southeast at 318 metres (1,043 ft). There is 3,794 kilometres (2,357 mi) of coastline marked by numerous bays, straits, and inlets. The number of islands and islets is estimated at some 2,355 (including those in lakes). Two of them are large enough to constitute separate counties: Saaremaa and Hiiumaa. A small, recent cluster of meteorite craters, the largest of which is called Kaali is found on Saaremaa, Estonia.

What is Estonia's highest mountain point?
---
A: the Suur Munamägi


Problem: Washington University in St. Louis:

Although Chancellor Wrighton had noted after the 2004 debate that it would be "improbable" that the university will host another debate and was not eager to commit to the possibility, he subsequently changed his view and the university submitted a bid for the 2008 debates. "These one-of-a-kind events are great experiences for our students, they contribute to a national understanding of important issues, and they allow us to help bring national and international attention to the St. Louis region as one of America's great metropolitan areas," said Wrighton.

Who said "These common events are a great experience for our students..." in 2008?
