Problem: Crucifixion of Jesus:

Although almost all ancient sources relating to crucifixion are literary, the 1968 archeological discovery just northeast of Jerusalem of the body of a crucified man dated to the 1st century provided good confirmatory evidence that crucifixions occurred during the Roman period roughly according to the manner in which the crucifixion of Jesus is described in the gospels. The crucified man was identified as Yehohanan ben Hagkol and probably died about 70 AD, around the time of the Jewish revolt against Rome. The analyses at the Hadassah Medical School estimated that he died in his late 20s. Another relevant archaeological find, which also dates to the 1st century AD, is an unidentified heel bone with a spike discovered in a Jerusalem gravesite, now held by the Israel Antiquities Authority and displayed in the Israel Museum.

What was the average age of Roman soldiers?

Problem: 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?

Answer: 16,777,216

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Traditionally the annelids have been divided into two major groups, the polychaetes and clitellates. In turn the clitellates were divided into oligochaetes, which include earthworms, and hirudinomorphs, whose best-known members are leeches. For many years there was no clear arrangement of the approximately 80 polychaete families into higher-level groups. In 1997 Greg Rouse and Kristian Fauchald attempted a "first heuristic step in terms of bringing polychaete systematics to an acceptable level of rigour", based on anatomical structures, and divided polychaetes into:
When did Greg Rouse begin trying to categorize planets?

Context and question: Witherspoon et al. (2007) have argued that even when individuals can be reliably assigned to specific population groups, it may still be possible for two randomly chosen individuals from different populations/clusters to be more similar to each other than to a randomly chosen member of their own cluster. They found that many thousands of genetic markers had to be used in order for the answer to the question "How often is a pair of individuals from one population genetically more dissimilar than two individuals chosen from two different populations?" to be "never". This assumed three population groups separated by large geographic ranges (European, African and East Asian). The entire world population is much more complex and studying an increasing number of groups would require an increasing number of markers for the same answer. The authors conclude that "caution should be used when using geographic or genetic ancestry to make inferences about individual phenotypes." Witherspoon, et al. concluded that, "The fact that, given enough genetic data, individuals can be correctly assigned to their populations of origin is compatible with the observation that most human genetic variation is found within populations, not between them. It is also compatible with our finding that, even when the most distinct populations are considered and hundreds of loci are used, individuals are frequently more similar to members of other populations than to members of their own population."
Studying increasing number of groups require an increasing number of what?
Answer: markers

Question: The evolutionary relationships and heredity of a group of organisms is called its phylogeny. Phylogenetic studies attempt to discover phylogenies. The basic approach is to use similarities based on shared inheritance to determine relationships. As an example, species of Pereskia are trees or bushes with prominent leaves. They do not obviously resemble a typical leafless cactus such as an Echinocactus. However, both Pereskia and Echinocactus have spines produced from areoles (highly specialised pad-like structures) suggesting that the two genera are indeed related.
Is there an answer to this question: What would be an indication of a shared inheritance in two cacti?

Answer: spines produced from areoles

Problem: Germans:

The Nazis, led by Adolf Hitler, attempted to unite all the people they claimed were "Germans" (Volksdeutsche) into one realm, including ethnic Germans in eastern Europe, many of whom had emigrated more than one hundred fifty years before and developed separate cultures in their new lands. This idea was initially welcomed by many ethnic Germans in Sudetenland, Austria, Poland, Danzig and western Lithuania, particularly the Germans from Klaipeda (Memel). The Swiss resisted the idea. They had viewed themselves as a distinctly separate nation since the Peace of Westphalia of 1648.

The Swiss has viewed themselves as their own country since what year?

A:
1648
