What were the great powers before World War I? Which do you think was the most powerful? The weakest? Why? In 1897, the German foreign secretary stated, "In one word: We wish to throw no one into the shade, but we demand our own place in the sun." What did he mean? How might his statement be considered fair? How might someone today criticize the statement? What were the alliances among the great powers before World War I? Why did the alliances exist? Why didn't they prevent the war? Why do you think losing Bulgaria as an ally was a loss for Serbia and Russia? Why were the Balkans such a problem area in Europe? Do you see other areas of the world today with problems similar to those that existed in the Balkans? Explain. What was the annexation crisis of 1908? How important do you think it was in leading to World War I? Explain.

explanation:

answer:   migrations were important in the neolithic period. "two major migrations passing through southeastern europe were confirmed by the means of archaeo-genetic studies."

the first migration was the early neolithic period -- 6,000 before common era (bce) -- when the first farmers, from anatolia -- asia minor -- spread through europe. the second migration occurred during the early bronze age (3,000-2,500 bce) when the so-called "steppe population," from the eurasian steppe, replaced much of northern europe's previous population.

the first farmers of northern and western europe passed through southeastern europe with limited hunter-gatherer genetic admixture, which occurs when two or more previously isolated populations begin interbreeding. however, some groups that remained mixed extensively -- without the male-biased, hunter-gatherer admixture that prevailed later in the north and west, according to latest discoveries. southeastern europe continued to be a nexus between east and west, with intermittent genetic contact with the steppe people up to 2,000 years before the migrations that replaced much of northern europe's population.

"in some places, hunter-gatherers and incoming farmers seem to have mixed very quickly," says iain mathieson, a geneticist at the university of pennsylvania, who was first author of the paper. "but, mostly, the two groups remained isolated, at least for the first few hundred years. these hunter-gatherers had been living there for thousands of years, and it must have been quite a shock to have these new people show up -- with a completely different lifestyle and appearance."

the correct answer is 50.
