Question: The most commonly given starting point for the Middle Ages is 476, first used by Bruni.[A] For Europe as a whole, 1500 is often considered to be the end of the Middle Ages, but there is no universally agreed upon end date. Depending on the context, events such as Christopher Columbus's first voyage to the Americas in 1492, the conquest of Constantinople by the Turks in 1453, or the Protestant Reformation in 1517 are sometimes used. English historians often use the Battle of Bosworth Field in 1485 to mark the end of the period. For Spain, dates commonly used are the death of King Ferdinand II in 1516, the death of Queen Isabella I of Castile in 1504, or the conquest of Granada in 1492. Historians from Romance-speaking countries tend to divide the Middle Ages into two parts: an earlier "High" and later "Low" period. English-speaking historians, following their German counterparts, generally subdivide the Middle Ages into three intervals: "Early", "High", and "Late". In the 19th century, the entire Middle Ages were often referred to as the "Dark Ages",[B] but with the adoption of these subdivisions, use of this term was restricted to the Early Middle Ages, at least among historians.

Question: That year, Queen began The Works Tour, the first tour to feature keyboardist Spike Edney as an extra live musician. The tour featured nine sold-out dates in October in Bophuthatswana, South Africa, at the arena in Sun City. Upon returning to England, they were the subject of outrage, having played in South Africa during the height of apartheid and in violation of worldwide divestment efforts and a United Nations cultural boycott. The band responded to the critics by stating that they were playing music for fans in South Africa, and they also stressed that the concerts were played before integrated audiences. Queen donated to a school for the deaf and blind as a philanthropic gesture but were fined by the British Musicians' Union and placed on the United Nations' blacklisted artists.
Is there an answer to this question: Which Queen tour was the first to feature Spike Edney?

Answer: Spike Edney

Question: The use of the term Lander (Lands) dates back to the Weimar Constitution of 1919. Before this time, the constituent states of the German Empire were called Staaten (States). Today, it is very common to use the term Bundesland (Federal Land). However, this term is not used officially, neither by the constitution of 1919 nor by the Basic Law (Constitution) of 1949. Three Lander call themselves Freistaaten (Free States, which is the old-fashioned German expression for Republic), Bavaria (since 1919), Saxony (originally since 1919 and again since 1990), and Thuringia (since 1994). There is little continuity between the current states and their predecessors of the Weimar Republic with the exception of the three free states, and the two city-states of Hamburg and Bremen.
Is there an answer to this question: What are the two city-states in Germany?

Answer:
Hamburg and Bremen
