Which group benefited most directly from the
supreme court decision in dred scott v. sanford
(1857)?
(1) abolitionists (3) slave owners
(2) immigrants (4) enslaved persons

The correct answer here is 3: slave owners. Dred Scott v. Sanford was a landmark case of the US Supreme Court. The Court had to decide whether an African-American, slaves or not, whose ancestors were bought and imported into the United States as slaves and were later sold as such could be counted as citizens of the United States. This also included their right to be represented in the federal court and that the government could not in the federal territories that were admitted in the Union after the original creation of the United States regulate slavery. Scott was in the free, brought there by his slavers and he wanted to sue them there for his freedom. The court rejected his request. This case one of the many things that contributed to the Civil War as the abolitionists movements in the North were against this verdict.

i believe the answer is d.

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."
