QUES: Controversy persists over whether the Rus’ were Varangians (Vikings) or Slavs. This uncertainty is due largely to a paucity of contemporary sources. Attempts to address this question instead rely on archaeological evidence, the accounts of foreign observers, legends and literature from centuries later. To some extent the controversy is related to the foundation myths of modern states in the region. According to the "Normanist" view, the Rus' were Scandinavians, while Russian and Ukrainian nationalist historians generally argue that the Rus' were themselves Slavs. Normanist theories focus on the earliest written source for the East Slavs, the Russian Primary Chronicle, although even this account was not produced until the 12th century. Nationalist accounts have suggested that the Rus' were present before the arrival of the Varangians, noting that only a handful of Scandinavian words can be found in modern Russian and that Scandinavian names in the early chronicles were soon replaced by Slavic names. Nevertheless, archaeological evidence from the area suggests that a Scandinavian population was present during the 10th century at the latest. On balance, it seems likely that the Rus' proper were a small minority of Scandinavians who formed an elite ruling class, while the great majority of their subjects were Slavs. Considering the linguistic arguments mounted by nationalist scholars, if the proto-Rus' were Scandinavians, they must have quickly become nativized, adopting Slavic languages and other cultural practices.

QUES: There is a close connection between machine learning and compression: a system that predicts the posterior probabilities of a sequence given its entire history can be used for optimal data compression (by using arithmetic coding on the output distribution) while an optimal compressor can be used for prediction (by finding the symbol that compresses best, given the previous history). This equivalence has been used as a justification for using data compression as a benchmark for "general intelligence."

What has been used as a benchmark for "general intelligence"?

ANS: data compression
QUES: Nevertheless, although a distinction between lawful and unlawful hunting is undoubtedly permissible, it is certain that a bishop can absolutely prohibit all hunting to the clerics of his diocese, as was done by synods at Milan, Avignon, Liège, Cologne, and elsewhere. Benedict XIV (De synodo diœces., l. II, c. x) declared that such synodal decrees are not too severe, as an absolute prohibition of hunting is more conformable to the ecclesiastical law. In practice, therefore, the synodal statutes of various localities must be consulted to discover whether they allow quiet hunting or prohibit it altogether.

What did Synods at Milan, Avignon, Liege, Cologne, and elsewhere do?
What is the answer?
ANS:
prohibit all hunting to the clerics
