Who is most likely to have said the following:

" blacks must learn job-specific skills that will them escape the plight of the sharecropper."

The sentence "Blacks must learn job-specific skills that will help them escape the plight of the sharecropper."  was said by Booker T. Washington.

Explanation:

Booker Taliaferro Washington (1856 - 1915) was born in Virginia, United States. He was a writer and educator, and was a remarkable African-American leadership who achieved a prominent position in the history of the formation of black population thinking in the US. Washington acted in an atmosphere of uncertainty, after the American Civil War, defending the technical education of the black population. His thoughts are clear in the quoted sentence. He had an enviable oratory and his public pronouncements were well received by the conciliatory and pleasant words addressed to the public. In all, Washington contributed a lot to African Americans’ life, mainly by forming a hand that specializes in technical works and raising their self-esteem.

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."
