The problem: Answer a question about this article:
The Roman Empire reached its greatest territorial extent during the 2nd century AD; the following two centuries witnessed the slow decline of Roman control over its outlying territories. Economic issues, including inflation, and external pressure on the frontiers combined to make the 3rd century politically unstable, with emperors coming to the throne only to be rapidly replaced by new usurpers. Military expenses increased steadily during the 3rd century, mainly in response to the war with Sassanid Persia, which revived in the middle of the 3rd century. The army doubled in size, and cavalry and smaller units replaced the legion as the main tactical unit. The need for revenue led to increased taxes and a decline in numbers of the curial, or landowning, class, and decreasing numbers of them willing to shoulder the burdens of holding office in their native towns. More bureaucrats were needed in the central administration to deal with the needs of the army, which led to complaints from civilians that there were more tax-collectors in the empire than tax-payers.
What is another term for the Roman landowning class?
****
The answer: curial

So that the maximum number of colors can be accurately reproduced on your computer screen, each color has been given a code number, or sRGB, which tells your computer the intensity of the red, green and blue components of that color. The intensity of each component is measured on a scale of zero to 255, which means the complete list includes 16,777,216 distinct colors and shades. The sRGB number of pure red, for example, is 255, 00, 00, which means the red component is at its maximum intensity, and there is no green or blue. The sRGB number for crimson is 220, 20, 60, which means that the red is slightly less intense and therefore darker, there is some green, which leans it toward orange; and there is a larger amount of blue,which makes it slightly blue-violet.
What is the total number of possible sRGB colors?
****
The answer: 16,777,216
