Problem: Greeks:

The classical period of Greek civilization covers a time spanning from the early 5th century BC to the death of Alexander the Great, in 323 BC (some authors prefer to split this period into 'Classical', from the end of the Persian wars to the end of the Peloponnesian War, and 'Fourth Century', up to the death of Alexander). It is so named because it set the standards by which Greek civilization would be judged in later eras. The Classical period is also described as the "Golden Age" of Greek civilization, and its art, philosophy, architecture and literature would be instrumental in the formation and development of Western culture.

What did the Greeks do that made it possible for the contraction of the opposite of the Western Civilization ?

Problem: The earliest known document in Galician-Portuguese dates from 1228. The Foro do bo burgo do Castro Caldelas was granted by Alfonso IX of León to the town of Burgo, in Castro Caldelas, after the model of the constitutions of the town of Allariz. A distinct Galician Literature emerged during the Middle Ages: In the 13th century important contributions were made to the romance canon in Galician-Portuguese, the most notable those by the troubadour Martín Codax, the priest Airas Nunes, King Denis of Portugal and King Alfonso X of Castile, Alfonso O Sabio ("Alfonso the Wise"), the same monarch who began the process of establishing the hegemony of Castilian. During this period, Galician-Portuguese was considered the language of love poetry in the Iberian Romance linguistic culture. The names and memories of Codax and other popular cultural figures are well preserved in modern Galicia and, despite the long period of Castilian linguistic domination, these names are again household words.
During what era did Galician literature emerge?

Answer: Middle Ages

Sociocultural anthropology has been heavily influenced by structuralist and postmodern theories, as well as a shift toward the analysis of modern societies. During the 1970s and 1990s, there was an epistemological shift away from the positivist traditions that had largely informed the discipline.[page needed] During this shift, enduring questions about the nature and production of knowledge came to occupy a central place in cultural and social anthropology. In contrast, archaeology and biological anthropology remained largely positivist. Due to this difference in epistemology, the four sub-fields of anthropology have lacked cohesion over the last several decades.
When was there a shift towards the positivist traditions?
A: unanswerable

Brass, which is an alloy of copper and zinc, has been used since at least the 10th century BC in Judea and by the 7th century BC in Ancient Greece. Zinc metal was not produced on a large scale until the 12th century in India and was unknown to Europe until the end of the 16th century. The mines of Rajasthan have given definite evidence of zinc production going back to the 6th century BC. To date, the oldest evidence of pure zinc comes from Zawar, in Rajasthan, as early as the 9th century AD when a distillation process was employed to make pure zinc. Alchemists burned zinc in air to form what they called "philosopher's wool" or "white snow".
Brass is an alloy of what two elements?
A:
copper and zinc
