Which best explains how galileo defended himself against persecution by the catholic church?
a. he considered it a sin to speak out against the church.
b. he preferred to let his experiments speak for themselves.
c. he accused the church of favoring opinion over truth.
d. he blamed the church for squashing scientific freedom.

C. He accused the Church of favoring opinion over truth.

Explanation:

Galileo was a Catholic, but he despised above all things arguments based on the principle of authority. Apparently, this irreducible critical spirit had inherited it from his father who taught him to freely doubt of anything in order to seek the truth. On the other side, the Church was concerned about modern science for two reasons: the first is that it promoted free interpretations of the Holy Scriptures, and the second is that the Heliocentric model, supported by Galileo's observations, was associated with an ancient pagan influence. In the trial, Galileo said that the Catholic elites were favoring opinion and the principle of authority over truth. However, in the end, he had to deny his observed evidence in order to save his life from being burnt at the bonfire under the charge of heresy.

a. there was serious competition for tech jobs at the downtown clinic.

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."
