PART A: Which statement best expresses the central idea of the text? A)Scientists continue to study the plague’s spread through Europe in the 14th century because they can’t understand how it spread so aggressively.
B)Upper-class people lost their influence over lower classes of people as it became clear that even they would not be spared from the plague.
C)The plague modernized health and medicine in Europe as people realized that doctors were unintentionally spreading the plague rather than treating it.
D)While the plague was devastating to Europe’s population, it also reshaped their social order to allow for greater equality.

PART B: Which detail from the text best supports the answer to Part A?
A)“Common medicinal practices of the time period, like bloodletting, would have also contributed to the spread of the disease. For example, high standards of hygiene were not practiced; physicians didn’t even wash their hands.”
B)“Many lost faith in the Catholic Church as people continued to die from the plague. Some converted to Protestantism, while others became more interested in secular ideas about the world.”
C)“Scientists and historians today still study the Black Death. They continue to develop vaccines, but with our current knowledge of bacteria, it is no longer the threat it once was.”
D)“The plague upended traditional structures like religion and feudalism that were once the cornerstones of medieval life. It redirected the path of European history, propelling it towards the modern age, though at the cost of millions of lives.”

hello,

your answer whould be 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."

the emancipation proclamation was the aim of the war change to include the freeing of slaves in addition to preserving the union. the 13th amendment, which abolished slavery in the u.s. was passed on december 6th 1865.

as promised, lincoln waited to unveil the proclamation until he could do so with success from the union military advance. on september 22nd 1862, after a victory at antietam, he publicly announced a preliminary emancipation proclamation, declaring all slaves free in the rebellious states as of january 1st 1863.
