Context and question: Before the reign of Henry VIII, the sovereign always granted his or her assent in person. The sovereign, wearing the Imperial State Crown, would be seated on the throne in the Lords chamber, surrounded by heralds and members of the royal court—a scene that nowadays is repeated only at the annual State Opening of Parliament. The Commons, led by their speaker, would listen from the Bar of the Lords, just outside the chamber. The Clerk of the Parliaments presented the bills awaiting assent to the monarch, save that supply bills were traditionally brought up by the speaker. The Clerk of the Crown, standing on the sovereign's right, then read aloud the titles of the bills (in earlier times, the entire text of the bills). The Clerk of the Parliaments, standing on the sovereign's left, responded by stating the appropriate Norman French formula.
Nowadays, when is the only time a formal assention ceremony occurs?
Answer: the annual State Opening of Parliament
Context and question: Beginning with the Paris Exposition of 1878, the instrument's popularity rebounded. The Exposition was one of many stops for a popular new performing group the Estudiantes Españoles (Spanish Students). They danced and played guitars, violins and the bandurria, which became confused with the mandolin. Along with the energy and awareness created by the day's hit sensation, a wave of Italian mandolinists travelled Europe in the 1880s and 1890s and in the United States by the mid-1880s, playing and teaching their instrument. The instrument's popularity continued to increase during the 1890s and mandolin popularity was at its height in "early years of the 20th century." Thousands were taking up the instrument as a pastime, and it became an instrument of society, taken up by young men and women. Mandolin orchestras were formed worldwide, incorporating not only the mandolin family of instruments, but also guitars, double basses and zithers.
 What popular group didn't perform at the Paris Exposition?
Answer: unanswerable
Context and question: Rurik led the Rus' until his death in about 879, bequeathing his kingdom to his kinsman, Prince Oleg, as regent for his young son, Igor. In 880-82, Oleg led a military force south along the Dnieper river, capturing Smolensk and Lyubech before reaching Kiev, where he deposed and killed Askold and Dir, proclaimed himself prince, and declared Kiev the "mother of Rus' cities." Oleg set about consolidating his power over the surrounding region and the riverways north to Novgorod, imposing tribute on the East Slav tribes. In 883, he conquered the Drevlians, imposing a fur tribute on them. By 885 he had subjugated the Poliane, Severiane, Vyatichi, and Radimichs, forbidding them to pay further tribute to the Khazars. Oleg continued to develop and expand a network of Rus' forts in Slav lands, begun by Rurik in the north.
What year did Oleg conquer the Drevlians?
Answer:
883
