There are now forty-seven evening classes meeting at the House weekly, twenty-five evening clubs for adults, seventeen afternoon clubs for children, the Hull-House Music School, a choral society for adults, a children's chorus, a children's sewing school, a training school for kindergartners, a trades union for young women. In daily use are the nursery, the kindergarten, the playground, the penny provident bank, an employment bureau, a sub-station of the Chicago post office. A trained nurse reports to the house every morning and noon, to take charge of the sick-calls for the neighborhood; a kindergartner visits daily sick and crippled children. The coffeehouse serves an average of 250 meals daily, and furnishes noonday lunches to a number of women's clubs; soups and broths and wholesome food are brought by neighbors from its kitchen, and bread from its bakery, adorned with the label of the bakers' unions, goes out to the Lewis Institute, to grocery stores, to neighbors' tables. Using this statement, describe at least four different services that were provided for the poor by Hull House in Chicago, and explain how these services would improve living conditions.

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."
