Problem: Great Plains:

With the arrival of Francisco Vazquez de Coronado, a Spanish conquistador, the first recorded history of encounter between Europeans and Native Americans in the Great Plains occurred in Texas, Kansas and Nebraska from 1540-1542. In that same time period, Hernando de Soto crossed a west-northwest direction in what is now Oklahoma and Texas. Today this is known as the De Soto Trail. The Spanish thought the Great Plains were the location of the mythological Quivira and Cibola, a place said to be rich in gold.

Problem: Galicia (Spain):

Topographically, a remarkable feature of Galicia is the presence of many firth-like inlets along the coast, estuaries that were drowned with rising sea levels after the ice age. These are called rias and are divided into the smaller Rias Altas ("High Rias"), and the larger Rias Baixas ("Low Rias"). The Rias Altas include Ribadeo, Foz, Viveiro, Barqueiro, Ortigueira, Cedeira, Ferrol, Betanzos, A Coruna, Corme e Laxe and Camarinas. The Rias Baixas, found south of Fisterra, include Corcubion, Muros e Noia, Arousa, Pontevedra and Vigo. The Rias Altas can sometimes refer only to those east of Estaca de Bares, with the others being called Rias Medias ("Intermediate Rias").

What does Rias Altas mean?

A: High Rias

Problem: Heian period:

A struggle for succession in the mid-twelfth century gave the Fujiwara an opportunity to regain their former power. Fujiwara no Yorinaga sided with the retired emperor in a violent battle in 1156 against the heir apparent, who was supported by the Taira and Minamoto (Hogen Rebellion). In the end, the Fujiwara were destroyed, the old system of government supplanted, and the insei system left powerless as bushi took control of court affairs, marking a turning point in Japanese history. In 1159, the Taira and Minamoto clashed (Heiji Rebellion), and a twenty-year period of Taira ascendancy began.

In what year did no Yorinaga side with the emerors heir apparent?

Problem: Beer:

Cask-conditioned ales (or cask ales) are unfiltered and unpasteurised beers. These beers are termed "real ale" by the CAMRA organisation. Typically, when a cask arrives in a pub, it is placed horizontally on a frame called a "stillage" which is designed to hold it steady and at the right angle, and then allowed to cool to cellar temperature (typically between 1113 C or 5255 F), before being tapped and venteda tap is driven through a (usually rubber) bung at the bottom of one end, and a hard spile or other implement is used to open a hole in the side of the cask, which is now uppermost. The act of stillaging and then venting a beer in this manner typically disturbs all the sediment, so it must be left for a suitable period to "drop" (clear) again, as well as to fully conditionthis period can take anywhere from several hours to several days. At this point the beer is ready to sell, either being pulled through a beer line with a hand pump, or simply being "gravity-fed" directly into the glass.
