Input: Franco-Prussian War
The causes of the Franco-Prussian War are deeply rooted in the events surrounding the unification of Germany. In the aftermath of the Austro–Prussian War of 1866, Prussia had annexed numerous territories and formed the North German Confederation. This new power destabilized the European balance of power established by the Congress of Vienna in 1815 after the Napoleonic Wars. Napoleon III, then the emperor of France, demanded compensations in Belgium and on the left bank of the Rhine to secure France's strategic position, which the Prussian chancellor, Otto von Bismarck, flatly refused. Prussia then turned its attention towards the south of Germany, where it sought to incorporate the southern German kingdoms, Bavaria, Württemberg, Baden and Hesse-Darmstadt, into a unified Prussia-dominated Germany. France was strongly opposed to any further alliance of German states, which would have significantly strengthened the Prussian military.

What established the European balance of power in 1815?
Output: the Congress of Vienna

Article: Lighting design as it applies to the built environment is known as 'architectural lighting design'. Lighting of structures considers aesthetic elements as well as practical considerations of quantity of light required, occupants of the structure, energy efficiency and cost. Artificial lighting takes into account the amount of daylight received in an internal space by using Daylight factor calculation. For simple installations, hand-calculations based on tabular data are used to provide an acceptable lighting design. More critical or optimized designs now routinely use mathematical modeling on a computer using software such as Radiance which can allow an Architect to quickly undertake complex calculations to review the benefit of a particular design.

Question: What type of factor calculation can be used to find out how much daylight is received in a internal space.
Ans: Daylight factor calculation.

The problem: Answer a question about this article:
Queen drew artistic influence from British rock acts of the 1960s and early 1970s, such as the Beatles, the Kinks, Cream, Led Zeppelin, Pink Floyd, the Who, Black Sabbath, Slade, Deep Purple, David Bowie, Genesis and Yes, in addition to American guitarist Jimi Hendrix, with Mercury also inspired by the gospel singer Aretha Franklin. May referred to the Beatles as being "our bible in the way they used the studio and they painted pictures and this wonderful instinctive use of harmonies." At their outset in the early 1970s, Queen's music has been characterised as "Led Zeppelin meets Yes" due to its combination of "acoustic/electric guitar extremes and fantasy-inspired multi-part song epics".
