Medicine was also studied, especially in southern Italy, where Islamic medicine influenced the school at Salerno.

The problem: Answer a question about this article:
In nature, the red color of blood comes from hemoglobin, the iron-containing protein found in the red blood cells of all vertebrates. The red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide. It also causes the red color of the planet Mars. The red sky at sunset and sunrise is caused by an optical effect known as Rayleigh scattering, which, when the sun is low or below the horizon, increases the red-wavelength light that reaches the eye. The color of autumn leaves is caused by pigments called anthocyanins, which are produced towards the end of summer, when the green chlorophyll is no longer produced. One to two percent of the human population has red hair; the color is produced by high levels of the reddish pigment pheomelanin (which also accounts for the red color of the lips) and relatively low levels of the dark pigment eumelanin.
What pigment is responsible for the color of leaves in fall?
****
The answer: anthocyanins

The Xbox 360 sold much better than its predecessor, and although not the best-selling console of the seventh-generation, it is regarded as a success since it strengthened Microsoft as a major force in the console market at the expense of well-established rivals. The inexpensive Nintendo Wii did sell the most console units but eventually saw a collapse of third-party software support in its later years, and it has been viewed by some as a fad since the succeeding Wii U had a poor debut in 2012. The PlayStation 3 struggled for a time due to being too expensive and initially lacking quality titles, making it far less dominant than its predecessor, the PlayStation 2, and it took until late in the PlayStation 3's lifespan for its sales and game titles to reach parity with the Xbox 360. TechRadar proclaimed that "Xbox 360 passes the baton as the king of the hill – a position that puts all the more pressure on its successor, Xbox One".
What problem hurt Nintendo's Wii console?
****
The answer: collapse of third-party software support in its later years


The problem: Answer a question about this article:
Red is the traditional color of warning and danger. In the Middle Ages, a red flag announced that the defenders of a town or castle would fight to defend it, and a red flag hoisted by a warship meant they would show no mercy to their enemy. In Britain, in the early days of motoring, motor cars had to follow a man with a red flag who would warn horse-drawn vehicles, before the Locomotives on Highways Act 1896 abolished this law. In automobile races, the red flag is raised if there is danger to the drivers. In international football, a player who has made a serious violation of the rules is shown a red penalty card and ejected from the game.
What is a football player shown before being ejected from a match?
****
The answer:
a red penalty card
