Problem: Late Middle Ages:

As the European population was severely reduced, land became more plentiful for the survivors, and labour consequently more expensive. Attempts by landowners to forcibly reduce wages, such as the English 1351 Statute of Laborers, were doomed to fail. These efforts resulted in nothing more than fostering resentment among the peasantry, leading to rebellions such as the French Jacquerie in 1358 and the English Peasants' Revolt in 1381. The long-term effect was the virtual end of serfdom in Western Europe. In Eastern Europe, on the other hand, landowners were able to exploit the situation to force the peasantry into even more repressive bondage.

Problem: Ruben Studdard emerged as the winner, beating Clay Aiken by a small margin. Out of a total of 24 million votes, Studdard finished just 134,000 votes ahead of Aiken. This slim margin of victory was controversial due to the large number of calls that failed to get through. In an interview prior to season five, executive producer Nigel Lythgoe indicated that Aiken had led the fan voting from the wildcard week onward until the finale.
How many votes were cast for the finale?

The two travel to the hotel and discover White's secret room where they find co-ordinates pointing to Oberhauser's operations base in the desert. They travel by train to the nearest station, but are once again confronted by Hinx; they engage in a fight throughout the train in which Mr Hinx is eventually thrown off the train by Bond with Swann's assistance. After arriving at the station, Bond and Swann are escorted to Oberhauser's base. There, he reveals that Spectre has been staging terrorist attacks around the world, creating a need for the Nine Eyes programme. In return Spectre will be given unlimited access to intelligence gathered by Nine Eyes. Bond is tortured as Oberhauser discusses their shared history: after the younger Bond was orphaned, Oberhauser's father, Hannes, became his temporary guardian. Believing that Bond supplanted his role as son, Oberhauser killed his father and staged his own death, subsequently adopting the name Ernst Stavro Blofeld and going on to form Spectre. Bond and Swann escape, destroying the base in the process, leaving Blofeld to apparently die during the explosion.
Who will be given unlimited access to intelligence gathered by Ten Eyes?
A: unanswerable

Context and question: The range is mostly located in the United States but extends into southeastern Canada, forming a zone from 100 to 300 mi (160 to 480 km) wide, running from the island of Newfoundland 1,500 mi (2,400 km) southwestward to Central Alabama in the United States.[discuss] The range covers parts of the islands of Saint Pierre and Miquelon, which comprise an overseas territory of France. The system is divided into a series of ranges, with the individual mountains averaging around 3,000 ft (910 m). The highest of the group is Mount Mitchell in North Carolina at 6,684 feet (2,037 m), which is the highest point in the United States east of the Mississippi River.
What country do the Appalachian mountains extend into?

Question: The style and role of any minority leader is influenced by a variety of elements, including personality and contextual factors, such as the size and cohesion of the minority party, whether his or her party controls the White House, the general political climate in the House, and the controversy that is sometimes associated with the legislative agenda. Despite the variability of these factors, there are a number of institutional obligations associated with this position. Many of these assignments or roles are spelled out in the House rule book. Others have devolved upon the position in other ways. To be sure, the minority leader is provided with extra staff resourcesbeyond those accorded him or her as a Representativeto assist in carrying out diverse leadership functions. Worth emphasis is that there are limits on the institutional role of the minority leader, because the majority party exercises disproportionate influence over the agenda, partisan ratios on committees, staff resources, administrative operations, and the day-to-day schedule and management of floor activities.

QUES: A sample rate of 44.1 kHz is almost always used, because this is also used for CD audio, the main source used for creating MP3 files. A greater variety of bit rates are used on the Internet. The rate of 128 kbit/s is commonly used, at a compression ratio of 11:1, offering adequate audio quality in a relatively small space. As Internet bandwidth availability and hard drive sizes have increased, higher bit rates up to 320 kbit/s are widespread.
