Problem: In 1913 the Zliten mosaic, a Roman mosaic famous for its many scenes from gladiatorial contests, hunting and everyday life, was discovered in the Libyan town of Zliten. In 2000 archaeologists working in Leptis Magna, Libya, uncovered a 30 ft length of five colorful mosaics created during the 1st or 2nd century AD. The mosaics show a warrior in combat with a deer, four young men wrestling a wild bull to the ground, and a gladiator resting in a state of fatigue, staring at his slain opponent. The mosaics decorated the walls of a cold plunge pool in a bath house within a Roman villa. The gladiator mosaic is noted by scholars as one of the finest examples of mosaic art ever seen a "masterpiece comparable in quality with the Alexander Mosaic in Pompeii."
When was the Zliten mosaic discovered?
The answer is the following: 1913

Problem: From 1904 to 1907, the Herero and the Namaqua took up arms against the Germans and in calculated punitive action by the German occupiers, the 'first genocide of the Twentieth Century' was committed. In the Herero and Namaqua genocide, 10,000 Nama (half the population) and approximately 65,000 Hereros (about 80% of the population) were systematically murdered. The survivors, when finally released from detention, were subjected to a policy of dispossession, deportation, forced labour, racial segregation and discrimination in a system that in many ways anticipated apartheid.
What was the war against the German occupiers considered?
The answer is the following: first genocide of the Twentieth Century

Problem: Although inefficient, incandescent light bulbs have an advantage in applications where accurate color reproduction is important, since the continuous blackbody spectrum emitted from an incandescent light-bulb filament yields near-perfect color rendition, with a color rendering index of 100 (the best possible). White-balancing is still required to avoid too "warm" or "cool" colors, but this is a simple process that requires only the color temperature in Kelvin as input for modern, digital visual reproduction equipment such as video or still cameras unless it is completely automated. The color-rendering performance of incandescent lights cannot be matched by LEDs or fluorescent lights, although they can offer satisfactory performance for non-critical applications such as home lighting. White-balancing such lights is therefore more complicated, requiring additional adjustments to reduce for example green-magenta color casts, and even when properly white-balanced, the color reproduction will not be perfect.
What is the color rendering index of an incandescent light?
The answer is the following: 100

Problem: The German Renaissance has bequeathed the city some noteworthy buildings (especially the current Chambre de commerce et d'industrie, former town hall, on Place Gutenberg), as did the French Baroque and Classicism with several hotels particuliers (i.e. palaces), among which the Palais Rohan (1742, now housing three museums) is the most spectacular. Other buildings of its kind are the "Hotel de Hanau" (1736, now the city hall), the Hotel de Klinglin (1736, now residence of the prefet), the Hotel des Deux-Ponts (1755, now residence of the military governor), the Hotel d'Andlau-Klinglin (1725, now seat of the administration of the Port autonome de Strasbourg) etc. The largest baroque building of Strasbourg though is the 150 m (490 ft) long 1720s main building of the Hopital civil. As for French Neo-classicism, it is the Opera House on Place Broglie that most prestigiously represents this style.
How many museums does the Palais Rohan hold?
The answer is the following:
three
